DUCT WORK All duct work, supply and return, must be properly sized for the design airflow requirement of the equipment. Air Conditioning Contractors of America (ACCA) is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage. Refer to Maximum ESP of operation Electric Heat Tabl ...

FIGURE 4 ELECTRIC HEAT CLEARANCE W30H1, W36H1, W42H1, W48H1, W60H1 WARNING A minimum of 1/4 inch clearance must be maintained between the supply air duct and combustible materials. This is required for the first 3 feet of ducting. It is important to insure that the 1/4 inch minimum spacing is maintained at all points. Failure to do this could result in overheating the combustible material and may result in a fire ca ...

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. If this is the case, the unit serial p ...

START UP THESE UNITS REQUIRE R-410A REFRIGERANT AND POLYOL ESTER OIL. GENERAL: 1. Use separate service equipment to avoid cross contamination of oil and refrigerants. 2. Use recovery equipment rated for R-410A refrigerant. 3. Use manifold gauges rated for R-410A (800 psi/250 psi low). 4. R-410A is a binary blend of HFC-32 and HFC-125. 5. R-410A is nearly azeotropic - similar to R-22 and R-12. Although nearly azeotropic, charg ...

START UP (Continued) IMPORTANT INSTALLER NOTE For improved start up performance wash the indoor coil with a dish washing detergent. HIGH & LOW PRESSURE SWITCH All W**H wall mounted air conditioner series models are supplied with a remote reset for the high and low pressure switch. If tripped, this pressure switch may be reset by turning the thermostat off then back on again. THREE PHASE SCROLL COMPRESSOR START UP INFORMATION ...

SEQUENCE OF OPERATION COOLING – Circuit R-Y makes at thermostat pulling in compressor contactor, starting the compressor and outdoor motor. The G (indoor motor) circuit is automatically completed on any call for cooling operation or can be energized by manual fan switch on subbase for constant air circulation. HEATING – A 24V solenoid coil on reversing valve controls heating cycle operation. Two thermostat options, one ...

TROUBLESHOOTING SOLID STATE HEAT PUMP CONTROL TROUBLESHOOTING PROCEDURE 1. NOTE: A thorough understanding of the defrost cycle sequence is essential. Review that section earlier in this manual prior to troubleshooting the control. Turn on AC power supply to unit. 2. Turn thermostat blower switch to “fan on” – the indoor blower should start. (If it doesn’t, troubleshoot indoor unit and correct problem.) 3. Turn therm ...

CHECKING TEMPERATURE SENSOR OUTSIDE UNIT CIRCUIT 1. Disconnect temperature sensor from board and from outdoor coil. 2. Use an ohmmeter and measure the resistance of the sensor. Also use ohmmeter to check for short or open. 3. Check resistance reading to chart of resistance. Use sensor ambient temperature. (Tolerance of part is ± 10%.) 4. If sensor resistance reads very low, then sensor is shorted and will not allow proper ...
