OPERATIVE AND PREVENT REFRIGERANT FROM
ACCUMULATING IN OIL.
The control center off-on switch should be turned to
the “Off” position any time compressor operation is
not desired.
If the control voltage is supplied by a transformer, the
transformer should be rated at 2 KVA, with an inrush
rating of 12 KVA minimum at 80% power factor and
95% secondary voltage. For control wire sizing, refer
to the N.E.C. article 215 and 310. In the absence of
complete information to permit calculations, the volt-
age drop should be physically measured.
Control Interlocks
Water flow interlock terminals are provided on the
control center terminal strip. See field connection
diagram in the Electrical Data or in cover of control
center for proper connections.
The purpose of the water flow interlocks is to prevent
compressor operation until both the source water and
condenser water pumps are running and flow is
proven.

Operation of the source water pump may be to cycle
the pump with the compressor or it may be operated
continuously. The hot water (condenser) pump nor-
mally will be run continuously. The holding coil of
the cooling tower pump motor starter must be rated at
115 volts 60 Hz with a maximum 25 volt-ampere rating.
All interlock contacts must be rated for no less than 10
inductive amps. The alarm circuit provided in the
control center utilizes 115 volts. The alarm used should
not draw more than 10 volt-amperes.
TESTING CONTROL CIRCUIT
The installing contractor should complete all field
connections to the Templifier control panel after which
he should check out all remote interlocks for proper
operation. Do not disturb the internal wiring of the
control center or change the factory settings of
operating and safety controls.
At the time of startup the McQuay Service Technician
will completely check out the power and control
circuits. Final power connections to the compressor
should be made only after the McQuay pre-startup
inspection.
