UNIT IDENTIFICATION

Each unit is assigned a unique series of identifying numbers which are stamped on the unit nameplate. As soon as the unit is received, these identifications should be checked with the shipping papers and project infor­mation. If any discrepancies exist, contact your McQuay representative immediately.
Some McQuay Templifiers are equipped with a second condenser as required by project conditions.
In addition to the unit nameplate shown in Figure 1, each component has a nameplate affixed with certain data for the installer, including electrical data for the compressors and oil pumps.
sentatives, and normally consists of properly setting the unit in place and connecting the necessary wiring and piping services to the machine.
All McQuay Templifiers must be started only by a
McQuay Service Representative. The installer should make no attempt to start the machine before the complete system checkout has been made by McQuay and the unit has been initially started.

SAFETY CONSIDERATIONS

McQuay equipment is designed to provide safe and reliable service when properly installed and operated within the design specifications. The installer and operator should observe good safety precautions to prevent damage to the equipment or injury ‘to per­sonnel. Particular attention should be given to the following:
.
Do not climb on the unit or step on electrical or refrigerant lines.
.
Never exceed specified test pressures. Verify allow­able test pressures by checking the instruction literature and/or the equipment nameplates.
.
Do not use oxygen to purge or to pressurize the unit.
.
Do not obstruct or valve off any safety or relief devices.
Never open valves or connections under pressure in a way that can cause loss of refrigerant or oil or create a personnel hazard.
Nameplate and warning/instruction tags should not be removed.
Fluorocarbon refrigerants must be handled with caution and release to the atmosphere should be minimized.
Use only the correct refrigerant nameplate.
Only qualified electricians should make electrical installations.
Make certain that rigging equipment is adequate for the unit weights.

RECEIVING AND HANDLING

INSTALLATION

The unit should be inspected immediately after receipt for possible shipping damage.
All
McQuay
Centrifugal Templifier Heat Pumps are
shipped F.O.B. factory and all claims for handling and
shipping damage are the responsibility of the consignee.
Leave the shipping skid in place until the unit is in its final position. This will aid in handling the equipment.
Extreme care should be used when rigging the equip­ment to prevent damage to the control center, or refrigerant piping.
On units with top mounted compressors, the unit can
be lifted by fastening the rigging hooks to the 4
corners of the evaporator where the rigging eyes are
located. (See Figure 2.) Spreader bars should be used
between the rigging lines to prevent damage to the control center and other components.
On units with side mounted compressors, the unit can be lifted by the three corner fitting eyes and the extended eye at the compressor end. The center of gravity is located approximately where the discharge line enters the upper condenser shell. Adjust cable or chain lenghs accordingly. The compressor support is not designed to support the full weight of the unit. Therefore, unit must be lifted so that it is level or canted to assure that the compressor supports leave the ground first and touch down last. Spreader
bars are a must. (See Figure 3). For equipment weights for rigging and installation
requirements, refer to the certified equipment data.
