Open SV2.• Connect a pressure-proof hose to the outlet of thepressure regulator, then slightly open the valve at thetop of the cylinder in order to purge the air from thehose. After purging, close the valve.• Connect the other end of the hose to SV1 and fix itwith a hose band.• Check that V1, V2, V3, B, SV1 are fully closed.• Open the V3 and B-valve and then open SV1.Liquid trapPurge pumpNote: B-valve should be closed after the solution ischarged to the chiller.• Using the pressure regulator, charge a small amount ofN 2gas into the chiller.• Watch the vacuum gauge while N 2gas is charged.When the pressure inside the chiller reaches therequired pressure, close SV1, V3, and B-valve. Thenclose the valve of the cylinder.• Remove the hose from SV1 and attach the service valvecap to the service valve with sealant.• Remove the pressure regulator and the vacuum gauge.• Close SV2.11

1.9 - Piping1.9.1 - Connect each pipe according to exhibit LE and thespecification drawings.• Make all necessary connections to the building chilled andcooling water systems. Ensure that all piping is adequatelysupported and that no strain is placed on the chillernozzles and connecting flanges.• Provide adequate temperature and pressure sockets or tapson all supply and return piping.1.9.2 - FlushingAll water system pipes must be flushed before the water iscirculated in the chiller.1.10 - Field wiringCE markingPower supply connections should be in accordance with CEand comply with overvoltage category III (IEC 60664). Allother connections should be in accordance with overvoltagecategory II. All wiring must be in accordance with CErequirements.• Refer to exhibit LF and the specification drawings forwiring connections.• Supply power to the hot water control valve and hot watershut-off valve.• Refer to chapter 2.3 - Electrical check.• A properly qualified electrician should carry out theelectrical wiring.1.11 - Purging (see Fig. 5)• Ensure that the power supply is continuous.• Remove nitrogen gas (refer to chapter 1.8.3.)• Fill the purge oil pump to the centre of the red mark ofpurge pump level gauge.• Turn on the control panel main breaker and the purgepump switch. Check the direction of rotation. If thedirection is wrong, turn off the power supply to the chiller.• Then change any two of the wires of main power supplysource. The chiller was connected with all wires meetingthe same phase. Run the purge pump continuously.• Connect the vacuum gauge (1 kPa) to SV2.- Open SV2.- Open V1, V3, and B-valve to purge the chiller.- After one hour open V2.• Operate the purge pump until the vacuum gauge shows 0.5kPa.

Fit a vinyl hoseto the attachment as shown in Fig. 5 and Fig. 7.• Open V1, close V2 and V3.• Continue operating the purge pump for one minute underthe conditions above. Then measure the volume of bubbles(the measured volume is called A ml). Do not submergethe vinyl hose more than 10 mm during this measurement.If bubbles collect, inspect and tighten the connectionsdownstream of V2 and V3. If bubbles still appear aftertightening, measure the volume collected for 10 minutes.• Open V1 and V3. Close V2. The gas ballast valve and theoil delivery valve should be closed.• Continue operating the purge pump under the conditionsabove. Measure the volume of bubbles for 10 minutes(the measured volume is called B ml). The measurementshould be repeated at least three times. During thesemeasurements the attained purge pump vacuum should bekept below 0.5 kPa.• B ml - A ml is the result of the bubble test.• After the bubble test, the gas ballast valve should beopened. The oil delivery valve should be opened to checkif any water is contained in the purge pump oil. If water isobserved, drain the water and charge with new oil.12

For the same reason the chilledwater volume must be higher than 10.5 litres/kW.General remarks on piping1. Equipment and parts outside the area surrounded bythe broken line are not supplied by Carrier. A hot watercontrol valve and a hot water shut-off valve shall beprovided, if specified in the scope of supply.2. For pipe connections and diameters refer to the dimensionaldrawings and specification tables.3. Ensure that the chilled water flow rate and cooling waterflow rate are in conformity with the standard value. If thechilled water flow rate sinks to under 50% of the standardvalue, the chiller will stop.4. Position the chilled water pump, cooling water pump, hotwater pump and expansion water tank correctly so that thechiller pressure does not exceed the set value.5. For cooling water temperature control refer to the chapter"Cooling water temperature control method".6. Separate chilled and cooling and hot water pumps shouldbe provided for each chiller.7. Provide a cooling water blow-down valve in the coolingtower inlet for water quality control.8. Install a filter in the chilled water, cooling water and hotwater pipes (10 mesh).9. Install stop valves on the chilled, cooling and hot waterinlet/outlet.10. Provide a thermometer and pressure gauge at the chilled,cooling and hot water inlet and outlet.11. Provide an air vent valve in each of the chilled and coolingwater lines at a point higher than the header.12. Install drain valves at the lowest positions betweenabsorption chiller and the stop valves of the chilled water,cooling water and hot water, and pipe them to the drainchannel.13. Install stop valves between the absorption chiller and stopvalves of all inlets and outlets for chemical cleaning of thewater circuit system.14. Install a cooling tower away from any exhaust gas outlet.28

4.4 - Exhibit LE (cont.)4.4.2 - Water treatmentAbsorption chillers use copper pipes to prevent corrosion dueto the use of fresh water (pipe material: JIS H 3300 C1201TS)But there is a possibility of corrosion due to water pollution orpoor water quality.Please follow the points below to prevent problems:• For chilled and cooling water refer to water qualitystandard JRA GL-02-1994 (see below). If the water doesnot comply with this standard, please contact a watertreatment specialist.• If coated steel pipe is used in the chilled and cooling waterlines, add corrosion inhibitor to the steel pipes and makesure that the rust does not adhere to the copper pipes.Please contact a water treatment specialist.If corrosive gas exists near the cooling tower, the corrosivecomponents can dissolve into the cooling water. Please ensurethat it is not located near a source of corrosive gas.If a heat storage tank is used in the chilled water line, pipecorrosion may occasionally occur due to dissolved oxygen orrust in the tank. In this case install a heat exchanger betweenchiller and tank, or contact a water treatment specialist.If the pipes are flushed before commissioning ensure that noforeign materials get into the chiller. Always flush the pipesusing the bypass piping for the chiller.If the chiller is installed in an existing system, rust in theexisting pipes may prevent the formation of the corrosioninhibitingfilm in the pipe.

In typical applicationsthe chiller is selected on the basis of the cooling watertemperature available at full load. This is 29.4°C.Case BIf the chiller operates during an intermediate season or inwinter, provide an automatic three-way control valve shown asabove.During operation of the chiller/heater keep the cooling waterentering temperature between 29.4°C and 18°C.During start-up however, a lower temperature is allowable untilthe operating conditions are reached.NOTES1.
