Your neighborhood will not feel uncomfortable with the
noise or expelled air.
It is easy to install the connecting pipes or cables.
Determine the air outlet direction where the discharged
air is not blocked.
There is no danger of fire due to leakage of inflammable
gas.
The piping length between the outdoor unit and the indoor
unit may not exceed the allowable piping length.
In the case that the installation place is exposed to strong
wind such as a seaside, make sure the fan operating
properly by putting the unit lengthwise along the wall or
using a dust or shield.(Refer to Fig.6-1)
If possible, do not install the unit where it is exposed to
direct sunlight.
If necessary, install a blind that does not interfere with the
air flow.

outdoor unit ,The condensate should be well drained
away by the drain hole to an appropriate place, so as not
to interfere other people.
Select the position where it will not be subject to snow
drifts, accumulation of leaves or other seasonal debris. If
unavoidable, please cover it with a shelter.
Locate the outdoor unit as close to the indoor unit as
possible.
If possible, please remove the obstacles nearby to
prevent the performance from being impeded by too little
of air circulation.
The minimum distance between the outdoor unit and
obstacles described in the installation chart does not
mean that the same is applicable to the situation of an
airtight room. Leave open two of the three
directions.(Refore to Fig.6-4, Fig.6-5)

Stop the heat pump, turn off the power, and reset the test cover
to its original position.
NOTE
The drain plug is used to empty the water-receiver for
maintenance of the heat pump. Please stuff it imposition
at all times during operation to avoid leakage.
Install the drain joint of the outdoor unit
8. CONNECT THE DRAIN PIPE
Install the drainpipe of the indoor unit
You can use a polyethylene tube as the drainpipe
(out-dia.37-39mm, in-dia.32mm). It could be bought at local
market or from your dealer.
Set the mouth of the drainpipe onto the root of the body's
pump-pipe, and clip the drainpipe and the out-let pipe sheath
(fittings) together firmly with the out-let pipe clasp (fitting).
The body's pump pipe and the drainpipe (especially the
indoor part) should be covered evenly with the out-let pipe
sheath (fittings) and be bound tightly with the constrictor to
prevent condensation caused by entered air.
To prevent water from flowing backwards into the heat pump
while the heat pump stops, please lean the drainpipe down
toward outdoor (outlet-side) at a degree of over 1/ 50. And
please avoid any bulge or water deposit. ( Refer to Fig.5-17.a
in the figure page)
Do not drag the drainpipe violently when connecting to
prevent the body from being pulled. Meanwhile, one
supportpoint should be set every 1~1.5m to prevent the
drainpipe from yielding (Refer to Fig.5-17a in the figure page).
Or you can tie the drainpipe with the connecting pipe to fix
it.(Refer to Fig.5-17.c in the figure page)
In the case of prolonged drainpipe, you had better tighten its
indoor part with a protection tube to prevent it from loosing.
If the outlet of the drainpipe is higher than the body's pump
joint, the pipe should be arranged as vertically as possible.
And the lift distance must be less than 200mm, otherwise the
water will overflow when the heat pump stops. (Refer to
Fig.5-18 in the figure page)
The end of the drainpipe should be over 50mm higher than
the ground or the bottom of the drainage chute, and do not
immerse it in water. If you discharge the water directly into
sewage, be sure to make a U-form aquaseal by bending the
pipe up to prevent the smelly gas entering the house through
the drain pipe.
Fit the seal into the drain joint, then insert the drain joint into the
base pan hole of outdoor, rotate 90° to securely assemble them.
Fit the seal into the drain joint, then insert the drain joint into the
base pan hole of outdoor, rotate 90° to securely assemble them.
Connect the drain joint with an extension drain hose (Locally
purchased), in case of the condensate draining off the outdoor
unit during the heating mode.
