8.5 Name Description of Components
in the Accessory Box
Note:
1. The after-sales installation personnel select the required parts
according to the different installation environment. Therefore,
some parts may not be needed for the installation. Please refer to
the actual installation.
2. No air out assembly for the models without the air discharge
function.
8.6 Installation of Indoor Unit
1. Install wall-mounted plate
● Use the hanging line method or leveling instrument to find the
level. The indoor unit must be installed horizontally and must not
be tilted left or right to prevent water leak.
● Fix the wall-mounted plate to the wall with screw after treatment
(such as pre-embedded plastic particles).
● After installation, pull the wall-mounted plate by hand to confirm
whether it is firmly fixed. After installation, the wall-mounted plate
should be able to withstand a weight of 60 kg, and the stress of
each fixing screw should be relatively uniform.

2. Connect the drain pipe
● Connect the drain pipe in the accessory to the outlet pipe of the
indoor unit, and fix it with two rounds of electrical tape.
● Take out the insulation tube in the accessory and wrap it on the
drain pipe.
● Wrap the insulation tube with wrapping tape. During the
wrapping, start from the connection between the outlet pipe of the
indoor unit and the insulation tube to avoid the movement of the
insulation tube after installation. The drain pipe should be inclined
from the inside to the outside to ensure that the condensate can
be discharged smoothly.
Note:
That the drain part of insulation pipe that wrapped in the indoor
side should be tightly connected with the casing outside the outlet
pipe of the indoor unit; the drain pipe should be inclined, and
there should be no twists, bumps, undulations, etc., and the outlet
should not be placed in the water, the pipelines which is prone to
corrosion or odor.
3. Indoor unit wiring
● The indoor unit has been connected to the power cord and
power cable, you only need to check for looseness.
Warning:
Because one end of the power cable is connected in the unit,
when the single unit conducts power-on test, the other end of
the power cable may be live, please pay attention to insulation
to avoid short circuit or electric shock. When the length of
the connecting wire is not enough, please contact the local
Service Center to reequip a dedicated wire with sufficient
length, and additional connection between the wires is not
allowed.
4. Install connecting pipe (subject to actual distribution)
● Due to the technical innovation and improvement of product,
there are currently two installation status and installation methods
for R32 refrigerant connection pipe parts: temper-evident nuts or
temper-evident boxes. Which will not affect the performance, use
and other effects of product due to improvement.
● Installation method:
Unfold the connecting pipe, bend the connecting pipe according
to the required length, open the nut on the indoor unit pipe,
align the cone mouth of the connecting pipe to the center of the
corresponding indoor unit pipe, tighten the nut by hand, and then
tighten with a torque wrench. Once the tamper-evident nut or
tamper-evident box is installed, it cannot be removed. If you need
to disconnect the indoor and outdoor units, cut and replace the
connector and re-weld.
1. For the indoor unit using temper-evident nut, a special non-
removable connector is used.
2. For the connecting pipe of indoor unit using the temper-evident
box, the delivered temper-evident box must be installed.
