6 5. Run refrigerant piping as directly as possi ble and avoid any unnecessary turns or bends. 6. Condensate piping can b e directed t hrough the insi de wall to an approved drain or straight outside. NOTE: The piping hole for condensate line must slope at a minimum pitch of 1 / 4 in.
7 TO I NST ALL THERMOST A T : If there is at least 3 / 8 in. of space between the back of indoor unit and wall: 1. Route thermostat wires (field-supplied) throu gh slot in right side or rear panel of indoo r unit (Fig. 3). 2. Route wires over refrigerant and drain piping as shown in Fig.
8 f. Refer to the outdoor unit Installation, Start-Up and Service Instructions for add itional information . g. Install a factory-supplied filter drier near the out- door unit. On heat pump systems, a bi-flow filter drier must be used. 3. Insulate and caulk wall ope nings to reduce air in filtra- tion and refrigerant pipe vibrations on structure.

All piping must follo w standard refr igerant piping techniques. 2. All wiring must comply with the applicab le local and national codes.
12 Step 7 — Install Thermostat — These systems use a 3-speed thermostat. The thermostat monitors the system opera- tion and controls the operating mode. T o change settings or re- fer to the thermostat Operating Instructions. Mount thermostat to a wall in the occupied space using 2 field-supplied screws.
13 Step 8 — Make Connections Between Indoor and Outdoor Units — The thermostat is wired between the indoor and outdoor units to make the system com plete. CHECK ACCURA TER METERING DEVICE — Th e co r- rect AccuRater (bypass type) refri gerant control is required for system capacity optimization.
