NOTE ON DRAINPIPE INS
TALLATION
•
When using an extended drainpipe, tighten
the indoor connection with an additional
protection tube. This prevents 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.
•
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 will
discharge water. Ensure that the drain hose
is placed in an appropriate area to avoid
water damage and slippage.
•
DO NOT
pull the drainpipe forcefully. This
could disconnect it.
