* Either the right rear or right side of the unit is suitable for fixing the drainpipe.
* The diameter of the drainpipe should be equal to or greater than that of the connecting pipe.
* Take the drainpipe as short as possible and slope downward at a gradient of at least 1/100
to prevent air pockets.(Refer to Fig.10)
* Use the attached drain hose ④ and clamp ⑤ .
* Insert the drain hose completely into the drain socket. Tighten the clamp within the range of
gray tape until the screw head is less than 4mm from the hose. (Refer to Fig.11,Fig.12)

(1). Align the flared end of the copper tube with the threaded connector, and then hand-tighten
the flared nut.
(2). Further tighten the flared nut with a torque wrench until the torque wrench sounds a “crack”.
(3). The bending of the pipe shall not be too small, otherwise the pipe may crack. A pipe bender
must be used when bending the pipe.
(4). Wrap the thermally untreated pipe and connectors with sponge and then tighten the sponge
with plastic tape.
Notes:
① .During the piping, do not pull any connector forcefully to prevent the capillary and other
pipes from cracking, which then would result in leakage.
② .The pipe should be properly supported in the way that its weight will not be borne by the
unit.
If the specification of the outdoor unit pipe joint does not conform to that of the indoor unit, then
the joint specification of the outlet pipe of the indoor unit takes precedence. A reducing nipple shall
be installed at the joint of the outdoor unit so as to make the joint of the outdoor unit compatible
with that of the indoor unit.

to prevent heat source from sunlight when
the unit is cooling, which helps to reduce
energy consumption.
* In case of ineffective ventilation,
open the window to ventilate room air
occasionally, meanwhile, close the window
timely for saving energy.
13
Free Match for North America
* Check electrical system (voltage and
frequency). Use the power supply indicated
on the nameplate of the unit to operate the
air conditioner and only fuses with specified
capacity should be done by technicians. Do
not use pieces of wire instead of fuse.
* If electric shock suddenly happens, turn
off the unit. If the unit is not to be used
for a long period, cut off the main power
supply.
* Do not insert objects into the air inlet or
outlet when the air conditioner is running
as it may cause damage or personal injury.
Also pay special attention when children
are around.
* Do not place any obstacles around
the indoor and outdoor unit to avoid of
inefficient performance or malfunction.
