2.6 Pipework & Brazing
Pipework to and from the unit should be selected to suit the application and not the connection size of
the unit. Pipework sizes should be selected to ensure pressure drop does not exceed an equivalent of 2K
at full load conditions.
Pipework must be designed to ensure good oil return, especially during low load conditions.
Pipework should be supported independently from the condensing unit in a way that prevents the
transmission of vibration to the units.
A competent engineer should install the refrigerant pipework to a high standard of refrigeration
practice. All pipework used must be clean and to refrigeration quality, all cuts should be made using a
pipe cutter, never a hacksaw, and care must be taken to remove all burrs and swarf.
Braze using silver bearing brazing rod and ensure that all joints are cleaned before brazing.
During brazing care should be taken to ensure that all components near joints should not be excessively
overheated, a wet cloth should be applied where necessary. Dry nitrogen should be passed through the
pipework during brazing to minimise oxidisation.
During brazing ensure the temperature of coils with vinyl coated fins does not exceed 150°C
as toxic fumes would be produced.
The Suction inlet and Discharge outlet connection stubs are located towards the rear of the, the suction
stub is 2 5/8”, the Discharge stub is 1 5/8”, ensure the holding charge has been safely released and cut
back the stubs and prepare the connections as required to match the system pipework, and braze
accordingly.
When brazing and leak testing are complete the suction line should be insulated with 3/4" thick Class ‘O’
insulation.
2.7 Pressure Testing
The unit has been thoroughly pressure tested during manufacture however after on site brazing is
complete all pipework should be pressure tested for leaks.
When pressure testing it is imperative that low and high side components are not over pressurised.
Low side components must not be subjected to any pressure greater than 12.6 Barg, high side
components must not be subjected to any pressure greater than 22.5 Barg.
Failure to adhere to these pressures will activate the safety bursting discs and relief valves, requiring
replacement.
During pressure testing the main Manual Reset High pressure switches may trip, ensure all switches are
reset, if required, after pressure testing.
Pressure testing must be by a currently recognised method.
Pressure testing using refrigerant must never be undertaken.

2.8 Electrical
NOTE : All Electrical connections to the unit should be made in accordance with IEE
regulations, 16 th Edition, with further attention to applicable local by-laws.
The units have been designed to accept multiple incoming 63A feeds, or with a single sub-main
supply with the Busbars, fitted to the unit.
IMPORTANT : If Separate incoming feeds are used the Busbars MUST BE REMOVED,
before wiring commences.
For a multiple supply 5 separate feeds are required as follows :
3 x TP&N for Compressor’s
1 x SP&N for Controls
1 x SP&N for RCD Socket, Lighting and Housing Evaporator.
All cabling should be of the correct rating and type, also adhering to M&S specifications.
Incoming connections should be made via the Main’s Incoming compartment situated on the far left of
the pack control panel. Cables should be routed through the bottom Glanding plate as shown in Fig. 2.
Cables should also be glanded or restrained to the glanding plate incorporated in the base of the mains
incoming termination panel.
Fig 2
The glanding plates may be removed for ease
of working.
Note : the glanding plates are not rated
to support weight of the incoming
supply cables, which must be supported
independently from the unit.
Incoming supplies should be connected to the
post terminals ensuring correct phase rotation
in all cases.
All incoming supplies should be properly
identified with special care being taken to
prevent any cross phasing between supplies.
IMPORTANT :
The supply to the RCD Socket MUST be
disconnected before any High Voltage
Insulation tests are carried out. Failure
to so will irrevocably damage the RCD
Socket.
See wiring diagram on page 39 for further
details.

2.9 EVACUATION
2.9.1 Holding Charge : The unit has been leak tested, dehydrated and filled with a holding charge of
‘dry air’ during manufacture. The holding charge should be released to atmosphere in a controlled
manner via the suction stub, liquid stub, and receiver service ports, not into the housing
compartment. Any valve opened to atmosphere must be closed after releasing the holding
charge.
2.9.2 Ensure that all system shut off valves are open as follows :
1. 2 5/8” Suction Ball Valve, under control panel, open.
2. Compressor Suction Service valves (Back seated with sealing cap on), on rear or top of
compressors.
3. Compressor Discharge Service valves (Back seated with sealing cap on) on top of compressors.
4. Compressor Oil return line shut off valves (Back seated with sealing cap on), on top of oil return
header x4.
5. All Valves in the condensing circuit installation.
6. Receiver service valves, (Back seated with sealing cap on).
7. Liquid filter bypass arrangement, top valve open, centre valve shut, bottom valve open. The
refrigerant flow must go through the drier.
8. Solenoid valves on the oil level floats and compartment cooler should be opened with manual solenoid
valve operating magnets.
Warning : Never energise any Solenoid coil when not fitted to its solenoid stem.
2.9.3 Compressor crank case heaters should be on during evacuation as follows :
1. Turn off all Isolators on the electrical cabinet compartment doors.
2. Open each compressor compartment door.
3. Switch all Compressor Overloads to the Off or ‘0’ position.
4. Switch MCB’s 1CB1, 2CB1, and 3CB1 to the on position
5. Switch all other MCB’s to the off position.
6. Close all electrical compartment doors.
7. Turn on Compressor 1, 2, and 3 isolators ONLY, do not turn on the common controls or Condenser
compartment isolators. The crank case heaters will now be energised.
2.9.4 The entire system should be evacuated prior to charging as follows:
Connect vacuum pump to the 1/4” flare connections on the suction and discharge service valves of
compressor 1 and 2, and if possible the receiver service valves. Ensure each service valve is mid seated,
the valve spindles should be screwed in a few turns from the back seated position to open the ports, and
the sealing caps replaced.
Evacuate the system to below 225 microns (0.3 mbar). The pump should be isolated and the system
pressure monitored. A rapid continuous rise could indicate a leak in the system.
Warning : DO NOT Start or Insulation Test the Compressors under Vacuum.
After evacuation all Solenoid coils MUST be replaced on their solenoid stems.

2.10 Refrigerant Charging
The unit should be charged with the specified refrigerant R404A until the sight glass is just clear at the
normal operating condition. R404A refrigerant must be charged as a Liquid, and never as a gas.
Charge the unit whilst under vacuum with liquid refrigerant via the access valve on top of the liquid
filter drier. Additional charge should be added at the evaporator distributor or immediately after
the expansion valve.
Liquid charging direct to the suction line is not permitted under any circumstances.
If after charging the unit is left with the power supply turned off, the compressor crankcase heaters
should be switched on for a minimum of 3 hours before the unit is started. This will ensure that the
compressor sumps are free from liquid refrigerant, see section 2.10.3 p12 for further info.
Warning : DO NOT allow Compressors to Short Cycle under low pressure whilst Charging.
2.11 Oil Recovery and Oil Charging
The unit is fitted with a High Pressure oil management system, which must be charged to its final oil
level during initial system operation. The oil separator incorporates an oil reservoir, which is pre-charged
with Polyolester oil, each compressor is also pre-charged with Polyolester oil.
If the unit is installed into a new installation some oil will be lost into the system pipework.
If the unit is installed into an existing installation oil may return to the separator from the rest of the
system due to the increased efficiency of the separator.
For a new installation add oil to maintain a level in the upper sight glass of the reservoir.
For an existing installation maintain an oil level in the lower sight glass of the reservoir.
After two days of system operation the oil level should be checked, and if required add or remove oil to
maintain a level in the upper sight glass of the reservoir for new and existing installations.
Add oil into the service connection on the shut off valve at the base of the separator/reservoir, ensure
the valve is back seated before removing the flare cap. Only suitable Polyolester oil, such as Bitzer BSE
32, or equivalent should be used. During normal operation each oil management float should show a
level between ½ and ¾ full sight glass.
2.12 Compressor Mounting Feet
All compressor mounting feet fixings should be checked to ensure they are
fully tightened, and re-tightened if necessary.
Check the fittings on the top of each compressor foot (1), the fitting (2)
should be firmly screwed on to the centre studding, and not be able to be
moved. See Fig 3.

2.13 Initial Starting / Running
Before operating the unit for the first time, check that components, motors, compressors, mountings and
electrical covers are secure.
When the unit has been installed, the relevant oil and refrigerant charges have been added, and the
correct controller settings entered it may be set in to normal operation as follows :
1. Ensure all shut off valves are open, (suction line, liquid line, condenser inlet valves, receiver inlet
and outlet valves, compartment cooler liquid and suction (MSHP only), and compressor discharge,
suction and oil return shut off valves).
2. Ensure the liquid filter drier bypass valve is closed and the refrigerant directed to pass through the
filter drier.
3. Ensure all solenoid-operating coils removed during evacuation have been replaced.
4. Turn off all electrical compartment isolators.
5. Open all compartments and ensure all MCB’s and Overloads are switched on or in the ‘1’ position.
Close all Compartment doors but leave isolators switched off.
6. Turn on the main control panel isolator and condenser panel isolator (if fitted), leaving compressor
isolators off.
7. Allow the controller to initialise, the suction pressure will be shown on the display, the discharge
pressure can be monitored on the backup millennium controller inside the common controls panel.
8. Turn on the isolator for compressor 1, and energise the evaporator liquid line solenoids. After the
compressor on delay the first stage will start under inverter control, increasing from low speed. Ensure
correct compressor operation.
9. Repeat step 7 one stage at a time until all compressors are running. If all compressors will not run at
the desired suction setting ensure all evaporators are running and that the system is adequately
charged. Ambient temperature conditions may also affect the number of stages required.
10. Check that the remote condenser fans operate and rotate in the correct direction. The airflow
direction is commonly across the motor and out through the fan guard.
11. Allow the unit to operate as normal for 48 hours and then carry out the 48 hours operation after
Initial Start-up Maintenance, as described in section 4.0.

Multiple Evaporator Applications
Where one unit is connected to multiple evaporators, operated independently from one another, it is vital
that the minimum saturated suction temperature remains within the operating envelope when the unit is
operating in low load conditions.
Staging of Compressors
The sequence controller incorporates a maximum number of starts for each compressor stage. This is
factory set to 10 starts per hour for all compressors and must not be raised.
Should plant pressures change rapidly during operation the controller will react accordingly starting and
stopping compressors as required.
Number of starts per hour higher than those above will reduce plant stability, increase power
consumption and lead to reduced component life and possible failure.
Failure to observe these limits will void the compressor warranty.

closed, to divert the refrigerant around the filter drier, see fig 6.
2. Connect a reclaim/recovery unit from the Drier service valve to the Suction schraeder, back seat the
drier service valve and recover any residual gas in the separator. Front seat the drier service valve when
complete.
3. Undo the central bolt 1 turn on the filter cap, rotate the cap and remove
4. Remove the core & cage assembly and unscrew the end.
5. Open the new cores and re-assemble onto the cage.
6. Insert the new core & cage into the drier shell, replacing the holding spring in front of the cage.
7. Replace the cap and turn until the alignment marks meet, tighten the centre bolt until hand tight, then
tighten one full turn.
8. Connect a vacuum pump to the Drier service valve, and run to remove air in the filter. Front seat
the drier service valve when complete, and replace it’s sealing cap.
9. Changeover the liquid bypass valve arrangement, Top Valve open, Centre valve shut, bottom
valve open, to restore the refrigerant flow through the filter.
Warning : The bypass arrangement must not be used for long periods of time as
contaminants and moisture will be allowed to pass through to the rest of the system.
The relative moisture level of the system can be monitored via the KMC (Wetech) detection alarm light
on the main control panel door.
After commissioning the moisture level Alarm light should not illuminate. If the moisture level increases
and the Alarm light illuminates action must be undertaken to reduce system moisture levels.

4.2 Every 3-6 months
The remote condensers should be cleaned to ensure correct operation of the condensing unit. When the
condenser coil is obstructed by dirt or rubbish, the unit will experience high condensing temperatures
which will result in higher running costs, loss of compressor efficiency and ultimately overheating of the
compressor and/or condenser fans.
The pressure drop across all filters should be measured, if above 0.5 Bar the filter elements should be
changed.
The sight glass moisture indicator and Wetech monitor should also be checked, and appropriate action
taken if moisture is shown to be present.
Warning : Safety Goggles must be worn when
inspecting or changing any pressure device.
The pressure relief valves and burst discs should be
inspected for any pressure release.
All burst discs are fitted with indicator gauges, and will
show system pressure if a release has occurred, see Fig 7.
Suction PRV’s should be manually inspected for a release.
Rupture Disc
Intact, No Release
(Needle at zero)
Rupture Disc blown,
Release has occurred
(Needle in Red band)
If a release has occurred or there is a requirement by the
customer maintenance schedule the relief valves and burst discs should be changed.
Main receiver and suction relief devices are connected via a changeover valve.
The changeover valve should be ‘back’ seated to the side requiring maintenance, the burst disc and/or
pressure relief valve can then be changed.
Warning : Beware of any residual refrigerant charge when removing PRV’s and Burst Discs,
Safety Goggles and Gloves must be worn.
The pressure relief valve and burst disc on the liquid filter bypass arrangement should be changed in a
similar fashion to the liquid filter cores, by first putting the liquid path into bypass, then reclaiming any
refrigerant. See section 4.1.4, p18 for further details.
A suitable thread sealant should be applied when fitting replacement equipment. Care must be taken
when tightening the replacement parts, by always using two spanners in a ‘scissor’ motion on the correct
area of the parts. Any replacement parts used must be of an equivalent specification and compliant with
applicable EC Directives.
Note : All PRV’s and Bursting Discs MUST be changed every 3 years , whether they have
vented or not.
4.3 Every 12 months
Check security of fixings, especially fans, motor and compressor mountings.
Check fan motors (fans should rotate freely).
Check refrigerant pipeline for damage and leaks.
Check tightness of all screwed components, including compressor service valves, component service
valves, and all pressure switch connections and hoses.

MSP-INV Installation and Operating Manual 7. Controls Logic
7.1 Compressor Sequencing
Issue 3 Page - 58 -
September 2007
The MSP-INV range consists of 4 models, each with nominal capacities of 50, 60, 80 and 100 kw, fitted
with RDM Mercury controls, hence named MSP050-INV, MSP60-INV, MSP80-INV, MSP100-INV.
The controls are effectively the same for all three units, with the only difference being the MSP080 and
100, which include a Cylinder Head unloader on the second compressor.
All main controls are 24V AC 50Hz.
Units also incorporate 240V and 415V Components.
7.1.1 Main Control – RDM Controller
The main control for MSP–INV unit’s compressor sequencing is the RDM Mercury 11-10V controller. The
controller monitors the suction pressure transducer, it outputs a 0-10V signal to the inverter which runs
the first compressor’s speed from 20Hz to 60Hz in response to the suction pressure changes.
When the first compressor is running at full speed the controller stages in the second and third
compressors as required to achieve the required duty. When a new compressor stage is bought in the
inverter compressor drops back to minimum speed, and then modulates as required.
Compressors 2 and 3 are fixed single speed units.
Compressor control is achieved using the ‘Section 1’ parameters of the controller.
The controller is factory set to maintain a suction pressure of 3.5 Barg (-9°C R404A).
The RDM controller uses ‘Fuzzy-Logic’ to determine which compressors to run based on their equivalent
size and deviation from the measured pressure to the set point.
Fig. 8 RDM Main control
7.1.2 Backup Control, all units
Should the main controller fail or if the millennium controller detects an out of range suction pressure the
backup controller is initiated and control transferred over from the main controller.
The compressor backup controller uses an RDM step controller type 6-10.
RDM 6-10 : the controller receives a signal from the Millennium controller to Stage Down or Stage Up.
When a Stage up signal is received the next compressor stage is brought in after the delay on time,
when a stage down signal is received the last compressor stage running is brought out after the delay

7.2 Compressor Safety Pressure Switches
All compressors are protected by a pair of safety pressure switches directly mounted to the compressor
heads. The LP switch (200-404-031), will cut the compressor out at 0.7 BarG, and cut back in at 2.2
BarG. The HP switch (200-404-032), will cut the compressor out at 22.0 BarG, and cut back in at 16.0
BarG. Both switches are Auto-Reset.
Compressors fitted with an oil pump are also protected with a Oil Pressure monitoring sensor.
(MSP100 = 2 & 3, MSP080 = Comp 3, MSP060 & MSP050 no oil sensors), this device monitors the pump
outlet pressure and trips out should the pressure fall below a set level. The device is factory set and can
not be adjusted. Should an Oil Differential switch trip a manual reset is required.
In addition to this, all compressors are protected by a combined HP/LP switch, which trips should the
unit try to operate outside of its application envelope.
All compressor switches are directly mounted to the compressor HP and LP connections They are
connected to the relevant compressor via a ¼” Schraeder connection.
Should a switch require replacement or disconnection follow the procedure in 4.5.2 on page 21.
Note : When removing a pressure switch from the compressor body take care not to unscrew the
1/8” NPT to 1/4" flare adapter beneath the hose connection.

7.3.6 MSP Main Controller Alarm Alias’s (RDM) – All Units
All MSP main controllers are factory set with the alarm names or ‘Aliases’ as shown in the tables above,
these relate to the controller input that the alarm is ‘hard-wired’ into.
To simplify identification it is recommended that these alarm Aliases are changed to reflect the nature of
the alarm. This can be done on the Front End Data Director terminal, via the set-up options.
Alarm aliases are as follows :
RDM Controller Reading Alarm Delay Function
(Factory Setting)
(New Alarm Alias)
Section 1 Stage 1 None Compressor No 1 Fault
Section 1 Stage 2 None Compressor No 2 Fault
Section 1 Stage 3 None Compressor No 3 Fault
General Fault 1 45 Mins Low Liquid Level
General Fault 2 45 Mins Moisture Detected
Important : Changes to the Front End information must only be made by authorised
personnel, if in doubt please contact RDM.
The ‘Run Smallest’ setting in the compressor controls options should not be enabled as it
will continue to hold off all other compressors if compressor 1 is held out on it’s anti cycle
timer. This will cause the backup system to intervene and flag up an alarm on the network.
The settings shown in this document must be adhered to, changes to the controller settings
that cause undesirable operation will invalidate the unit warranty.
7.3.7 Millennium Backup Controller
7.3.7.1 General
The Controller will monitor the operation of the Pack arrangement and if the Suction or Discharge
pressures stray above the pre-set limits the controller will intervene and take over control of the Pack. If
and when the suction pressure returns and remains within or below the preset dead band parameters
the MSP will return to main control after a period of 10 minutes. Backup can be forced in or cancelled
from the Main Controls panel front switch and reset button. The moisture content of the refrigerant is
also monitored via the KMC moisture sensor, commonly known as Wet Tech and the controller will
provide an alarm to the main RDM controller and controls panel above a preset level.
For MSHP units the controller will monitor the Housing temperature and run the Unit Cooler if required.
