SAFETY CONSIDERATIONS Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start-up, and service this equipment. Untrained personnel can perform basic maintenance functions such as cleaning coils. All other operations should be performed by trained service personnel.

SYSTEM REQUIREMENTS Allow sufficient space for airflow and servicing unit. See Fig. 7 — on page 8 for minimum required distances between unit and walls or ceilings. Piping IMPORTANT: Both refrigerant lines must be insulated separately. Table 3 lists the pipe sizes for the indoor unit. Refer to the outdoor unit installation instructions for other allowed piping lengths and refrigerant information.

INSTALLATION TIPS Mounting Plate Dimensions Ideal installation locations include: Different model sizes have different mounting plates. Ensure there’s enough room to mount the indoor unit (refer to Fig. 3−6).

Prepare the Refrigerant Piping The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall. NOTE: (Piping Angle) Refrigerant piping can exit the indoor unit from four different angles (see Fig. 12): 1. 2. 3. 4. 2. Prepare the Refrigerant Piping 1. Dissemble the louver. Left−hand side Left rear Right−hand side Right rear Fig. 14 — Dissemble the Louver 2. Open and fix the position of the panel.

3. Use the holder in the mounting plate to prop up the unit, allowing you enough space to connect the refrigerant piping, signal cable, and the drain hose. If there is no refrigerant piping embedded in the wall, perform the following steps: 1. 2. Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit. If the wall hole is behind the unit, keep the knock−out panel in place.

Bar 1. 2. 3. 4. 5. 6. 7. 8. Run the interconnecting piping and wiring from the outdoor unit to indoor unit. Run the interconnecting cable through hole in wall (outside to inside). Lift the indoor unit into position and route piping and drain through the hole in wall (inside to outside). Fit the interconnecting wiring into back side of indoor unit. Put the upper claw at back of indoor unit on upper hook of Mounting Plate, move indoor unit from side to side to see that it is securely hooked.

FINAL TUBING CHECK IMPORTANT: Ensure certain factory tubing on the indoor unit has not shifted during shipment. Ensure tubes are not rubbing against each other or any sheet metal. Pay close attention to feeder tubes, making sure wire ties on feeder tubes are secure and tight. Drain Connections Connect the drain line. The drain line must not have a trap anywhere in its length, must pitch downwards, and must be insulated up to the outside wall (see Fig. 27).

4. Connect the wired remote controller cable to the multi-function board using: a. X—Brown b. Y—Yellow c. E—Black (ground) d. 5V—Red (power) START-UP Test Operation Perform a test operation after completing gas leak and electrical safety check (see Fig. 36). 1. Push ON/OFF on the remote control to begin testing. NOTE: A protection feature prevents air conditioner from being activated for approximately 3 to 4 minutes. 2.

SYSTEM CHECKS 1. 2. 3. 4. 5. Conceal the tubing where possible. Make sure that the drain tube slopes downward along its entire length. Ensure all tubing and connections are properly insulated. Fasten tubes to the outside wall, when possible. Seal the hole through which the cables and tubing pass. Indoor Unit 1. 2. 3. 4.
