INSTALLATION INSTRUCTIONS

Step 3: Drill Wall Hole For Connective Piping

A hole must be drilled through the wall to the outside to accommodate the refrigerant piping, the drainage pipe and the signal cable that will connect the indoor and outdoor units.

1. Determine the location of the wall hole based on the position of the mounting plate. See Step 2 for mounting plate dimensions.
2. The wall hole should have a 65mm (2.5 in) diameter and it should be drilled on a downward angle to facilitate drainage. The outdoor end of the hole should be lower than the indoor end of the hole by 5 - 7 mm (0.2 - 0.275 in).
3. Place the protective wall cuff in the hole. This will protect the edges of the hole and will help seal the hole once the installation is complete.

Note: When drilling the wall hole, make sure to avoid wires, plumbing and other sensitive components that could be within the wall.

INSTALLATION INSTRUCTIONS

Step 4: Prepare Refrigerant Piping

The refrigerant piping is inside an insulating sleeve attached to the back of the unit. The piping must be prepared before passing it through the hole in the wall. Refer to the Refrigerant Piping Connection section for detailed instructions on pipe flaring and fl are torque requirements, etc.

1. Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit.
2. If the wall hole is behind the unit, leave the knock out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock out panel from the side of the unit. This will create a slot through which the piping can exit the unit. Use needle nose pliers if the plastic panel is difficult to remove.
3. Use scissors to cut down the length of the insulating sleeve to reveal approximately 15cm (6 in) of the refrigerant piping. This serves two purposes:
4. To facilitate the Refrigerant Piping Connection process
5. To facilitate gas leaks checks and allow a check for dents in the pipe
6. If existing connective piping is already embedded in the wall, proceed directly to Step 5: Connect The Drain Hose. If there is no embedded piping, connect the indoor unit's refrigerant piping to the connective piping that will join the indoor and outdoor units.
7. Based on the position of the wall hole relative to the mounting plate, determine the necessary angle of the piping. Grip the refrigerant piping at the base of the bend.
8. Slowly, with even pressure, bend the piping toward the wall hole. Do not dent or damage the pipe during the process.

Note on Piping Angle

Refrigerant piping can exit the indoor unit from four different angles:

• Left-hand side
• Left rear Be extremely careful not to dent or damage the piping
  Right-hand side while bending them away from the unit. Any dents in
• Left rear the piping will affect the unit's performance.

If electrical leakage is detected, turn off the unit immediately and call a licensed electrician to find and resolve the cause of the leakage.

WARNING

ALL WIRING MUST COMPLY WITH LOCAL AND NATIONAL ELECTRICAL CODES AND MUST BE INSTALLED BY A LICENSED ELECTRICIAN.

Gas Leak Checks

There are two acceptable methods of checking for gas leaks.

Soap and Water Method

Using a soft brush, apply soapy water or liquid detergent to all pipe connection points on the indoor and outdoor units. The presence of bubbles indicates a leak.

Leak Detector Method

If using a leak detector, refer to the device's operation manual for proper usage instructions.

Note: After completing gas leak checks, confirm that all piping connection points do not leak and make sure to replace the valve cover on the outdoor unit.
