—6— 5. Run refrigerant piping as directly as possible and avoid any unnecessary turns or ben ds . 6. Condensate piping can be dir ected through the inside wall to an approved drain or straight o utside. NO TE: The piping hole for condensate line must slope at a minimum pitch of 1 / 4 in.
—7— F . T o Install Thermostat: If there is at least 3 / 8 in. of space between the back of indoor unit and wall: 1. Route thermostat wires (fi eld-supplied) through slot in right side or rear panel of indoor unit (F ig. 3). 2. Route wires over refr igerant and drain piping as shown in Fig .
—8— 3. Insulate and caulk wall openings to reduce air infil- tration and refrigerant pipe vibrations on structure. 4. Evacuate piping, if necessary . If either refrigerant piping or the indoor coil is exposed to atmospheric conditions , it must be ev acua ted to 1000 microns to eliminate contamination and moisture in the system.
