F. To Install Thermostat: 3 If there is at least / in. of space between the back of indoor 8 unit and wall: 1. Route thermostat wires (field-supplied) through slot in right side or rear panel of indoor unit (Fig. 3). 2. Route wires over refrigerant and drain piping as shown in Fig. 12. IMPORTANT: Do not route wires under the piping, or wires a40-620 could impede air filter removal. Fig. 6 — Installing Hex-Head Mounting Bolts IV.

3. Attach plate with screws under piping hole. 3. Insulate and caulk wall openings to reduce air infil- tration and refrigerant pipe vibrations on structure. 4. Attach drain pipe with nylon wire tie passing through hole (Fig. 15). 4. Evacuate piping, if necessary. If either refrigerant piping or the indoor coil is exposed to atmospheric NOTE: Do not fasten nylon wire ties tight enough to conditions, it must be evacuated to 1000 microns to deform the insulation, as this affects its performance. e

VII. STEP 7 — INSTALL THERMOSTAT These systems use a 3-speed thermostat. The thermostat monitors the system operation and controls the operating mode. To change settings or refer to the thermostat Operat- ing Instructions. Mount thermostat to a wall in the occupied space using 2 field-supplied screws. Locate the thermostat in an area that is not subjected to drafts or direct sunlight through windows. Locate thermostat on an interior wall whenever possible. Figure 18 shows available thermostats.

The DFB logic checks the 10-minute defrost timer and the DFT. If the DFT opens in less than 10 minutes, the DFB switches the unit back to normal heating operation. If the DFT remains closed, the DFB switches the unit back to heating operation after 10 minutes. When the DFB changes back to heating mode, the RVR (reversing valve relay) is deenergized and the reversing valve switches back to heating operation. Both the outdoor and indoor fans come back on, and if necessary, the electric heater also

III. CLEAN INDOOR UNIT BOTTOM PANEL If the bottom panel of the unit becomes dirty or smudged, wipe the outside of the panel with a soft dry cloth. Use a mild liquid detergent and wipe off carefully with a dry cloth. IV. CLEAN INDOOR COIL To clean the coil, remove indoor unit bottom panel and vac- uum the coil fins, using care not to bend or damage fins. V. CLEAN OUTDOOR COIL (OUTDOOR UNIT) WARNING: Some metal parts and sharp fins of outdoor unit coil can cause personal injury during cleaning.
