12. Drainpipe Installation
The drainpipe is used to drain water from the unit. Improper installation may cause unit and property damage.
CAUTION
• Insulate all piping to prevent condensation, which could lead to water damage.
• If the drainpipe is bent or installed incorrectly, water may leak and cause a malfunction of the water-level switch.
• In
HEAT
mode, the outdoor unit will discharge water. Ensure that the drain hose is placed in an appropriate area to avoid
water damage and slippage due to frozen drain water.
• DO NOT pull the drainpipe forcefully as this could cause it to disconnect.
Indoor Drainpipe Installation
Install the drainpipe as illustrated below.
1. Cover the drainpipe with heat insulation to prevent condensation and leakage.
2. Attach the mouth of the drain hose to the unit’s outlet pipe. Sheath the mouth of the hose and clip it firmly with a pipe
clasp.
3. Ensure the drain pipe has flex by installing clear tube or similar to prevent drain breakage or cracking.
