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.
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.

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
-
consult the unit
nameplate.
Only qualified electricians should make electrical
installations.
Make certain that rigging equipment is adequate for
the unit weights.
INSTALLATION
RECEIVING AND HANDLING
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.
