TABLE 5
COOLING PRESSURE TABLE
Air Temperature Entering Outdoor Coil °F
Low side pressure ± 4 PSIG
High side pressure ± 10 PSIG
Tables are based upon rated CFM (airflow) across the evaporator coil. If there is any doubt as to correct operating charge
being in the system, the charge should be removed, system evacuated and recharged to serial plate charge weight.
NOTE:
Pressure table based on high speed condenser fan operation. If condensing pressures appear elevated check
condenser fan wiring. See “Condenser Fan Operation”.

Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
2
Based on 75C copper wire. All wiring must conform to the National Electrical Code and all local codes.
3
These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article
310 for power conductor sizing.
Caution
: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to note 8 of Table 310
regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a raceway.
* Top outlet supply option is available only factory installed and only on the selected models.
IMPORTANT:
While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in
accordance with the National Electrical Code and all local codes.
