Brief Introduction Of Installation
The installation of air-conditioner should meet with the “Installation Instruction”. The machine
must be installed correctly by professional technicians according to the “Installation
Instruction”.
(1) Guide to customer
①The customer should provide a suitable power supply source, its voltage should be in the
range of 90-110% of its rated voltage.
②The power supply circuit should have MCB leakage protection. The capacity should be
more than 1.5 times of the maximum current.
③Must use independent circuit and suitable grounding socket matching with the plug of
air-conditioner.
④The wiring must be installed by qualified electrician according to the electrical safety
requirements.
⑤The air-conditioner must be well grounded, the switch of the main power of air-conditioner
must be reliably grounded.
⑥The power supply wire, must be changed by qualified electrician.
(2) Installation Instruction
1. Installation order
Selection of the installation position Installing the air-conditioner
Expelling the air in the pipes and the indoor unit Connecting the pipes and wires
Testing
2. Selection of the installation position
Indoor Unit:
①There is no heating and steaming source nearby.
②No obstacles for installation position from nearby.
③Keep good air circulation.
④Convenient to adopt measures to reduce noises.
⑤Don’t install them near the doorway.
⑥Make sure to have the distance specified in the picture between the ceiling, wall, furniture
and other obstacles.
⑦2 meters high above the floor.
Outdoor Unit:
①In case that you put up a canopy to protect it from rains and sunrays, pay attention not to
cause any obstacles for the heating dispersion for the condenser.
②Don’t keep animals or plants near the installation location for the hot air from the outdoor
unit will affect them.
③Make sure to have the distance specified in the picture between ceiling, wall, furniture and
other obstacles.
④Stay away from heating source and inflammable air.
⑤The installation base and supporting frame should be strong and secure. The machine
should be at a level surface.

3. Installation
Outdoor Unit:
①The outdoor unit must be firmly fixed to avoid falling in
strong wind.
②Install on the cement base as in the drawing.
③If it is installed at seaside or at a place high above the
ground and with strong wind, the AC should be installed
against the wall to ensure the normal operation of the fan
and the blocking plate should be used.
④If it is an overhanging installation, the structure of the
mounting wall should be made of solid, cement or materials
with equivalent strength, and of sufficient support capacity.
Otherwise, measures such as reinforcement, support or
vibration damping should be adopted.
Indoor Unit
①First make changes to wall and make sure that is hard
and secure. Using four “+” type screws to fasten the
installation board onto the wall. Keep it level in horizontal
direction and perpendicular in vertical direction.
Otherwise it might cause water drips when air-conditioner
is running in cooling operation.
②Drill 70mm diameter pipe hole at the left lower or right
lower side of the installation board. The hole shall slant
outward slightly.
③Hang the indoor unit to the oard and make sure the
machine is in the middle of the board.
④Push the machine towards the left lower and right lower
side of the installation board until the hangers enter tightly
into the grooves (it produces “click” sound)
4. Check the water discharge
(1)Take off the frame from the unit cover.
Take off the front frame for maintenance according to the
following steps:
①As shown in the picture on the right, take off two covers
from the front frame and then unfasten two fixture screws.
②Pull the front frame towards yourself and take it off.
To put the front frame back, reverse the steps.
You should check whether the front frame is firmly fixed
into the fixture groove on the top.
(2)Check the water discharge
①Pour a cup of water into groove.
②Check whether the water flow through the water
discharge hole.

5. Pipe Connection
①Connect the pipe to the unit: point to the center of
pipe and fasten the connection screw at first by hand
and then by wrench until it is tightly fastened. The
fastening direction is shown in the picture.
②Pointing towards the center of pipe, fasten the screw
with strength.
③Wrench the screw in the end until you hear the “click”
sound.
6. The fixing of pipe
①Wrap up all pipe, water discharge and connection wire
from top to below.
②Cover the connection parts with insulation material and fix
them with two plastic rings.
③Wrap up the pipes with tape alongside the wall and fix
them to the wall with clips. These steps are usually adopted
when outdoor unit is installed below the indoor unit.
④In case that you want to have additional water discharge
pipe, the end of pipe should be within certain distance from
the floor (to prevent water from draining back into the pipe).
Fix it onto the wall so it won’t be swayed by wind.
⑤Wrap the pipes and connection wire well from below to top.
⑥Wrap up the pipes that are rounded up in the way shown in
the picture so it can prevent water from entering the room.
⑦Use clips or other fixture to fasten the pipes to the walls.

7. Expelling the air in the pipes and the indoor unit
Expelling the air: humid air in the refrigerating system might cause
trouble of compressor.
①Take off the cover from the stop valve and T-branch valve.
②Take off the auxiliary cover from the T-branch valve.
③Turn the stop valve rod anti-clock wise to an angle of 90 degree,
keep it open for 8 seconds and close the valve.
④Check whether there is air leakage at all connection parts of
pipes.
⑤Push the top rod of T-branch valve by hexagon wrench to expel
air.
⑥Repeat the third and fifth steps.
⑦Open the stop and T-branch valve with a hexagon wrench to
make the unit operate.
⑧No leakage is allowed, please check all the piping connection
parts. You must test the leakage, generally, it can be tested by soap
water.
8. Electrical connection
①Unscrew the screw, take off the control panel cover
from the unit.
②Cooling type: connect the wire to the related
connection point on the panel and connect the signal
connection plug.
Remarks: yellow and green cord should be connected to
connection point with mark.
③Fasten the fixture of wire to control panel.
④Screw up the control panel cover to its original place.
9. Test running
①Make sure that the pipes and wires are connected.
②Make sure that both the liquid valve and gas
valve on the side are completely open.
The connection of power source
¾Connect the wire to independent power source
socket.
¾Preparation of remote control.
¾Run the air-conditioner in cooling operation
mode for 30 minutes or longer.
Performance evaluation
¾Test the out and in air temperature.
¾Make sure that the temperature difference
between the out and in air is greater than 8oC.
10. Items of attention
①Fix the machine firmly, otherwise it will produce noise and vibration.
②Install the outdoor unit where it will not disturb your neighbor.
