Air conditioner INSTallATION General Information The S4BE series air conditioner is designed only for outdoor rooftop or ground level installations. This unit has been tested for capacity and efficiency in accordance with AHRI Standards and will provide many years of safe and dependable comfort, providing it is properly installed and maintained. Abuse, improper use, and/or improper maintenance can shorten the life of the appliance and create unsafe hazards.

Connecting Refrigerant Tubing Between the Indoor & Outdoor Unit CAUTION: ELECTRICAL WIRING WARNING: ELECTRICAL SHOCK OR FIRE HAZARD When servicing, cover or seal openings to minimize the exposure of the refrigerant system to air to prevent accumulation of moisture and other contaminants. To avoid risk of electrical shock, personal injury, or death, disconnect all electrical power to the unit before performing any maintenance or service. The unit may have more than one electrical supply.

• Provide power supply for the unit in accordance with the unit wiring diagram, and the unit rating plate. Connect the line-voltage leads to the terminals on the contactor inside the control compartment. • Use only copper wire for the line voltage power supply to this unit as listed in Table 1. Use proper code agency listed conduit and a conduit connector for connecting the supply wires to the unit. Use of rain tight conduit is recommended.

2. Verify blower wheel is spinning in direction indicated by arrow. Feel the air being circulated by the indoor blower and verify that it is cooler than ambient temperature. Listen for any unusual noises. If unusual sounds occur, determine the source of the noise and correct as necessary. 3. Verify HI and LO refrigerant pressures. 4. Allow the system to operate for several minutes and then set the temperature selector above room temperature. Verify the fan and compressor cycle off with the thermostat.

Charging the Unit in AC mode (At outdoor temperatures above 55° F for optimized sub-cooling of 10° F - 12° F.) 1. With the system operating at steady-state, measure the liquid refrigerant pressure (in psig) at the outdoor unit service valve. 2. Measure the liquid refrigerant temperature (in Fahrenheit) at the service valve. 3. Determine the required liquid refrigerant pressure from Table 3, (page 10), Table 4, (page 10), Table 5, (page 11), or Table 6, (page 11).
