NOTE: These capacities are gross ratings. For net capacities, determine the KW requirement of the supply air blower motor per the published BLOWER PERFORMANCE data. Convert
KW to MBH per the following equation and deduct this equivalent heat from the gross cooling ratings.
The KW input ratings listed above include the compressor and condenser fan motor(s).
UNIT OPERATION - 7-1/2, 10 & 12-1/2 TON
When the external control calls for cooling at terminal Y1:
1. The system controller (SC) is energized. The system con-
troller starts the tandem compressors and enables the
condenser fans by energizing contactor 1M (and 2M on
the 10 and 12-1/2 ton, 208/230 volt models).
The single condenser fan is energized with the compres-
sors on the 7-1/2 ton models.
Condenser fan motor #1 is energized with the compres-
sors on the 10 and 12-1/2 ton models while fan #2 is en-
abled with compressor operation. Fan motor #2 operation
is controlled through the Ambient Temperature Switch
(ATS) which will de-energize the motor when the ambient
temperature falls below 70
°F.
2. Safety Lockout: The system controller (SC) has a lockout
circuit to prevent compressor short-cycling on a safety
control with automatic reset. If the high or low refrigerant
pressure switches (HP or LP) open, the SC will enter
lockout mode.
SC provides a 90 second bypass of the low pressure switch
LP to prevent nuisance lockouts during unit start-up.
A malfunction light (24V, 2 A max. resistive load) can be en-
ergized through SC, by connecting the light between termi-
nals X and B on TB1.
NOTE: To reset the unit after a lockout:
A. Turn the system switch on the thermostat to the ‘‘OFF’’
position and back to the ‘‘COOL’’ position.
OR
B. Increase the set point of the room thermostat above the
temperature in the conditioned space and returning it to its
original setting.
If the unit continues to be shut down by one of its safety controls,
a service man should be called to determine the cause of the
problem. Repeated resetting of the lockout circuit may damage
the unit.
