9 Connect drain hose
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.
NOTE ON PURCHASING PIPES
Installation requires a polyethylene tube
(exterior diameter = 3.7-3.9cm, interior
diameter = 3.2cm), which can be obtained
at your localhardware store or dealer.
Indoor Drainpipe Installation
Install the drainpipe as illustrated in the following
Figure.
Cover the drainpipe with heat insulation to
1.
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. These units operate with a negative pressure
at the drain connections and a drain trap is
required. The trap needs to be installed as
close to the unit as possible. Make sure the
top of the trap is below the connection to
the drain pan to allow complete drainage
of the pan.

NOTE ON DRAINPIPE INSTALLATION
• When using an extended drainpipe,
tightenthe indoor connection with
an additionalprotection 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.
To prevent the pipe from sagging,
•
space hanging wires every 1-1.5m
(39-59").
If the outlet of the drainpipe is
•
higher than the body's pump joint,
use a lift pipe for the indoor unit's
exhaust outlet. The lift pipe must be
installed no higher than 55cm (21.7")
from the ceiling board. The distance
between the unit and the lift pipe
must be less than 20cm (7.9").
Incorrect installation could cause
water to flow back into the unit and
flood.
To prevent air bubbles, keep the
•
drain hose level or slightly tiled up
(<75mm / 3").
