3.3.3. Installing the wall hook bracket
(1) Install the wall hook bracket so that it is correctly positioned horizontally and vertically.
If the wall hook bracket is titled, water will drip to the floor.
(2) Install the wall hook bracket so that it is strong enough to support the weight of the unit.
• Fasten the wall hook bracket to the wall with 5 or more screws through the holes near
the outer edge of the bracket.
• Check that there is no rattle at the wall hook bracket.

CAUTION
Install the wall hook bracket both horizontally and vertically aligned.
Misaligned installation may cause water leakage.
3.3.4. Forming the drain hose and pipe
CAUTION
• Insert drain hose and drain cap securely. Drain should slope down to avoid water leakage.
• When inserting the drain hose, no other material than water should be applied.
Application of other material than water will cause deterioration of the hose, and may
cause water leakage.
• After you remove a drain hose, be sure to attach the drain cap.
• For drain hose piping in low temperature environment, you need to apply freeze
protection to prevent a frozen drain hose.
After cooling operation is performed in low temperature environment (when outdoor
temperature under 32 °F [0 °C]), water in the drain hose could be frozen. Frozen
drain water will block the water flow in the hose, and may cause water leakage at the
indoor unit.
