Drainpipe
Installation
NOTE ON DRAINPIPE INSTALLATION
•
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 1/100 to prevent water
from flowing back into the air conditioner.
•
To prevent the pipe from sagging, space
hanging wires every 1-1.5m (39-59”).
•
Incorrect installation could cause water to
flow back into the unit and flood it.
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
and 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.
NOTE ON PURCHASING PIPES
This installation requires a polyethylene tube
(outside diameter = 3.7-3.9cm, inside diameter
= 3.2cm), which can be obtained at your local
hardware store or dealer.
