Installing Vertical Runs (new construction shown) Line Set Isolation The following illustrations demonstrate procedures which ensure proper refrigerant line set isolation. This shows how to install line sets on vertical runs. NOTE: Similar installation practices should be used if line set is to be installed on exterior of outside wall. IMPORTANT: Refrigerant lines must not contact structure. Installing Horizontal Runs B This shows how to install line sets on horizontal runs.

■ All field wiring must be done in accordance with National Electrical Code requirements, applicable requirements of UL, or local codes, where applicable. ■ Electrical wiring, disconnect means and over-current protection are to be supplied by the installer. Refer to the rating plate for the maximum over-current protection, minimum circuit ampacity, and operating voltage. See the wiring diagrams in “Make Electrical Connections.

Charge Using Sub-cooling Method (Fixed Orifice/Thermal Expansion Valve Systems)—Outdoor Temperatures 65°F (18ºC) or Above Use this method if charging a fixed orifice or Thermal Expansion Valve system when the outdoor ambient temperature is 65°F (18ºC) or above. 1. Attach the manifold gauge hose to the liquid service port. 2. If the condensing unit pressures are stable, use a digital thermometer to record the liquid line temperature. 3. Record the liquid line pressure reading. 4.

Charge Using Approach Method (Thermal Expansion Valve Systems)—Outdoor Temperatures 65°F (18ºC) or Above Use this method if charging a Thermal Expansion Valve system when the outdoor ambient temperature is 65ºF (18ºC) or above. NOTES: ■ The following procedure is intended as a general guide. ■ Use on Thermal Expansion Valve systems only. ■ For best results, indoor temperature should 70°F (21ºC) to 80°F (27ºC). ■ Monitor system pressures while charging. 1.

SEQUENCE OF OPERATION Cooling Cycle Upon cooling demand, the thermostat closes circuit R to O and Y. Closing R to O and Y energizes the reversing valve for cooling operation and closes the heat pump contactor, starting the compressor and outdoor fan. The thermostat automatically closes R to G circuit, which also brings on the indoor fan at the same time. Upon satisfying cooling demand, the thermostat will open the above circuits and open the main contactor, stopping the compressor and outdoor fan.
