in the holes.
(3) Fix the wall-mounting frame on the wall with tapping screws
(ST4.2X25TA) and then check if the frame is firmly installed by
pulling the frame. If the plastic expansion particle is loose,
please drill another fixing hole nearby.
3. Install Wall-mounting Frame
(1) Choose the position of piping hole according to the direction
of outlet pipe. The position of piping hole should be a little
lower than the wall-mounted frame.(As show
n
in Fig.1)
4. Outlet Pipe
(1) The pipe can be led out in the direction of right, rear right,
left or rear left.(As show
n
in Fig.3)
(2) When selecting leading out the pipe from left or right, please
cut off the corresponding hole on the bottom case.(As show in
Fig.4)
(2) Open a piping hole with the diameter of Φ2
3/4inch on the
selected outlet pipe position.In order to drain smoothly, slant
the piping hole on the wall slightly downward to the
outdoor side with the gradient of 5-10°.(As show

(5) If a 18k indoor unit is to be connected with
a DHM or
DHW
outdoor unit, a transitional pipe joint (provided)
should be added at the pipe joint of indoor unit evaporator
assy as the
pipe joint of evaporator assy adopts pipe
diameter of Φ5/8.
Please refer to step 1-4 during installation.
6. Install Drain Hose
(1) Connect the
condensate
hose to the outlet pipe of indoor
unit.(As show
