Page 12: Wiring - Main Power
WIRING – MAIN POWER Refer to the unit rating plate for wire sizing information and maximum fuse or “HACR” type circuit breaker size. Each outdoor unit is marked with a “Minimum Circuit Ampacity”. This means that the field wiring used must be sized to carry that amount of current. Depending on the installed KW of electric heat, there may be two field power circuits required. -

WIRING – LOW VOLTAGE WIRING 230/208V, 1 phase and 3 phase equipment dual primary voltage transformers. All equipment leaves the factory wired on 240V tap. For 208V operation, reconnect from 240V to 208V tap. The acceptable operating voltage range for the 240 and 208V taps are: RANGE 253 - 216 220 - 187... -
Page 14: Heat Anticipation
HEAT ANTICIPATION Group A and Group B thermostats shown in Table 4 have a fixed heat anticipator for stage 1 with no adjustment required. Stage 2 has an adjustable anticipator for the W2 connection and fixed for the W3 connection. Both the W2 and W3 circuits are controlled by the stage 2 bulb. -
Page 15: Figure 9 Start Up Procedure Decal
IMPORTANT INSTALLER NOTE For improved start up performance, wash the indoor coil with a dish detergent. CRANKCASE HEATERS WH241 units are provided with compressor crankcase heat. These models have an insertion well-type heater located in the lower section of the compressor housing. This is a self-regulating type heater that draws only enough power to maintain the compressor at a safe temperature. -

Page 19: Figure 11 Fan Blade Setting
FAN BLADE SETTING DIMENSIONS Shown in the drawing below are the correct fan blade setting dimensions for proper air delivery across the outdoor coil. Any service work requiring removal or adjustment in the fan and/or motor area will require that the dimensions below be check and blade adjusted in or out on the motor shaft accordingly. -
Page 20: Pressure Tables
COOLING HEATING Low Side Pressure ± 2 PSIG High Side Pressure ± 5 PSIG Tables are based upon rated CFM (airflow) across the evaporator coil and should be found under section titled “Refrigerant Charge” elsewhere in manual. If there is any doubt as to correct operation charge being in the system, the charge should be removed, system evacuated, and recharged to serial plate instructions. -
