During refrigerant removal and storage operations followapplicable regulations. These regulations, permitting conditioningand recovery of halogenated hydrocarbons under optimumquality conditions for the products and optimum safetyconditions for people, property and the environment aredescribed in standard NFE 29795.Any refrigerant transfer and recovery operations must becarried out using a transfer unit. A 3/8” SAE connector onthe manual liquid line valve is supplied with all units forconnection to the transfer station. The units must never bemodified to add refrigerant and oil charging, removal andpurging devices. All these devices are provided with the units.Please refer to the certified dimensional drawings for the units.Do not drain water circuits containing industrial brines,without informing the technical service department at theinstallation site or a competent body first.Close the entering and leaving water shutoff valves andpurge the unit hydronic circuit, before working on thecomponents installed on the circuit (screen filter, pump, waterflow switch, etc.).Periodically inspect all valves, fittings and pipes of therefrigerant and hydronic circuits to ensure that they do notshow any corrosion or any signs of leaks.Do not re-use disposable (non-returnable) cylinders orattempt to refill them. It is dangerous and illegal. Whencylinders are empty, evacuate the remaining gas pressure,and move the cylinders to a place designated for theirrecovery. Do not incinerate.Do not attempt to remove refrigerant circuit components orfittings, while the machine is under pressure or while it isrunning. Be sure pressure is at 0 kPa before removingcomponents or opening a circuit.Any manipulation (opening or closing) of a shut-off valvemust be carried out by a qualified and authorised engineer.These procedures must be carried out with the unit shut-down.NOTE: The unit must never be left shut down with the liquidline valve closed, as liquid refrigerant can be trapped betweenthis valve and the expansion device. (This valve is situated onthe liquid line before the filter drier box.)Do not attempt to repair or recondition any safety deviceswhen corrosion or build-up of foreign material (rust, dirt,scale, etc.) is found within the valve body or mechanism. Ifnecessary, replace the device. Do not install safety valves inseries or backwards.CAUTION: Do not step on refrigerant lines. The lines canbreak under the weight and release refrigerant, causingpersonal injury.No part of the unit must use feet, racks or supports duringoperation. Periodically monitor and repair or if necessaryreplace any component or piping that shows signs of damage.Do not climb on a machine. Use a platform, or staging towork at higher levels.Use mechanical lifting equipment (crane, hoist, etc.) to lift ormove heavy components such as compressors or plate heatexchangers. For lighter components, use lifting equipmentwhen there is a risk of slipping or losing your balance.Use only original replacement parts for any repair or componentreplacement. Consult the list of replacement parts thatcorresponds to the specification of the original equipment.6
2 - PRELIMINARY CHECKS2.1 - Check equipment received• Inspect the unit for damage or missing parts. If damage isdetected, or if shipment is incomplete, immediately file aclaim with the shipping company.• Confirm that the unit received is the one ordered.Compare the name plate data with the order.• The unit name plate must include the followinginformation:- Version number- Model number- CE marking- Serial number- Year of manufacture and test date- Refrigerant used and refrigerant class- Refrigerant charge per circuit- Containment fluid to be used- PS: Min./max. allowable pressure (high and lowpressure side)- TS: Min./max. allowable temperature (high and lowpressure side)- Globe valve cut-out pressure- Pressure switch cut-out pressure- Unit leak test pressure- Voltage, frequency, number of phases- Maximum current drawn- Maximum power input- Unit net weightHigh pressure Low pressureMin.

If necessary, thedamaged parts must be repaired or replaced. See alsochapter “Maintenance”.2.2 - Moving and siting the unit2.2.1 - MovingSee chapter "Installation safety considerations"2.2.2 - Siting the unitAlways refer to the chapter "Dimensions and clearances" toconfirm that there is adequate space for all connections andservice operations. For the centre of gravity coordinates, theposition of the unit mounting holes, and the weight distributionpoints, refer to the certified dimensional drawing suppliedwith the unit.CAUTION: Only use slings at the designated lifting pointswhich are marked on the unit.Before siting the unit check that:• the permitted loading at the site is adequate or thatappropriate strengthening measures have been taken;• the surface is horizontal, flat and intact;• a channel is provided all the way around the unit to collectthe condensate water.• if the unit is not equipped with the accessory condensaterecovery pan, reference is made to the installation conditionsin chapter 10.4;• there is adequate space above the unit for air flow;• there are adequate support points and that they are in theright places;• the location is not subject to flooding;• units with the outdoor installation option should not beinstalled where there is a risk of snow build-up. In areasthat are subject to long periods of sub-zero temperaturesraise the unit to a higher level.Baffles may be necessary to deflect strong winds and toprevent snow from blowing directly into the unit. Theymust not restrict air flow into the unit.CAUTION: Before lifting the unit, check that all casingpanels are securely fixed in place. Lift and set down the unitwith great care. Tilting and jarring can damage the unit andimpair unit operation.The 30RY units can be hoisted with rigging. Coils shouldalways be protected against crushing while a unit is beingmoved. Use struts or spreader bars to spread the slings abovethe unit. Do not tilt a unit more than 15°.WARNING: Never push or lever on any of the enclosurepanels of the unit. Only the base of the unit frame is designedto withstand such stresses.7
