DRAIN PIPE INSTALLATION
The drainpipe is used to drain water away 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 water-level switch malfunction.
In HEAT mode, the outdoor unit discharges water. Ensure that
the drain hose is placed in an appropriate area to avoid water
damage and slippage. DO NOT pull the drainpipe forcefully,
doing so may disconnect it.
NOTE: Installation requires a PVC tube (exterior diameter = 1in
(25mm)) (depending on models), which can be obtained at
your local hardware store or dealer.
Indoor Pipe Installation
Install the drain pipe as shown in Figure 19.

NOTE: When using an extended drainpipe, tighten the indoor connection with an
additional protection tube to prevent it from pulling loose. The
drainpipe should slope downward at a gradient of at least 1/8" per foot
to prevent water from flowing back into the air conditioner. To prevent
the pipe from sagging, space hanging wires every 39-59"(1-1.5m). If the
outlet of the drainpipe is higher than the body's pump joint, provide a
lift pipe for the exhaust outlet of the indoor unit. The lift pipe must be
installed no higher than 29.5"(75cm) from the ceiling board and the
distance between the unit and the lift pipe must be less than 11.8"
(30cm) (depending on models). Incorrect installation could cause water
to flow back into the unit and flood. To prevent air bubbles, keep the
drain hose level or slightly tilted up (3"/<75mm) (some models).

1. Pass the drain hose through the wall hole. Ensure the water drains to a
safe location where it will not cause water damage or a slipping hazard.
NOTE: The drain pipe outlet should be at least 1.9" (5cm) above the ground.
If the drain pipe touches the ground, the unit may become blocked
and malfunction. If you discharge the water directly into a sewer, be
sure the drain has a U or S pipe to catch odors that might otherwise
come back into the house.
