Installing the pipes
Use suitable connecting pipes and equipment for
the refrigerant R410A.
Tighten the connections using two wrenches wor-
king in opposite directions.
Wrap all the refrigerant pipes and joints.
Use bolts to secure the unit to a flat, solid floor.
When mounting the unit on a wall or the roof, make
sure the support is firmly secured so that it cannot
move in the event of intense vibrations or a strong
wind.
Do not install the outdoor unit in pits or air vents
The refrigerant pipes must not exceed the maximum
heights 15m(18K&24K), 25m(30K&36K&42K).

Caution: Installation Must be Performed in
Accordance with the NEC/CEC by Authorized
Personnel Only.
Install the drain fitting and the drain hose
(for model with heat pump only)
Condensation is produced and flows from the out-
door unit when the appliance is operating in the
heating mode. In order not to disturb neighbours
and to respect the environment,install a drain fitting
and a drain hose to channel the condensate water.
Install the drain fitting and rubber washer on the
outdoor unit chassis and connect a drain hose to it
as shown in the figure.
When the adaptor is required for the connection of indoor
unit and the 24K、30K、36K、42K outdoor unit, the method
of pipe connection as follows:

Use suitable instruments for the refrigerant R410A.
Do not use mineral oils to clean the unit.
Ensure that the recommended space is left around the appliance.
When picking up and moving the units, you must be guided by trained and qualified person.
Do not use any other refrigerant than R410A.
MAINTENANCE INSTALLER
The installation must be done by trained and qualified service personnel with reliability according to this
manual.
Contact service center before installation to avoid the malfunction due to unprofessional installation.

INSTALLATION DIMENSION DIAGRAM
1.
Fix the support of outdoor unit (select it according to the actual installation situation)
Select installation location according to the house structure.
2. Fix the support of outdoor unit on the selected location with expansion
screws.
INSTALLER
NOTICE:
Take sufficient protective measures when installing the outdoor unit.
Make sure the support can withstand at least four times of the unit
weight.
The outdoor unit should be installed at least 3cm above the floor in
order to install drain joint. (for the model with heating tube, the
installation height should be no less than 20cm.)
For the unit with cooling capacity of 2300W ~ 5000W, 6 expansion
screws are needed; for the unit with cooling capacity of 6000W~
8000W, 8 expansion screws are needed; for the unit with cooling
capacity of 10000W~16000W, 10 expansion screws are needed.
As for the shape of drainage joint, please refer to the current product.
Do not install the drainage joint in the severe cold area. Otherwise,
it will be frosted and then cause malfunction.

Check Items
Is the installation reliable?
Has the gas leakage been checked?
Is the thermal insulation of the unit
sufficient?
Is the drainage smooth?
Does the power supply voltage accord
with the rated voltage specified on the
nameplate?
Are the lines and pipelines correctly
installed?
Are the models of lines in conformity
with requirements?
Are there any obstacles near the air
inlet and outlet of the indoor and out-
door units?
Have the length of refrigerating pipe
and refrigerant charge amount been
recorded?
Has the unit been safely grounded?
Problems Owing to Improper Installation
The unit may drop, vibrate or make noises
May cause unsatisfactory cooling (heating)
effect
May cause condensation and water dropping
May cause condensation and water dropping
The unit may bread down or the components
