User guideline
Precautions
The air conditioner must be correctly installed by installation technicians according to the attached Installation Manual , and the user himself should not install it.
Pre-installation precautions
Please confirm thatthe installation personnel are qualified in relevant installation service.If the airconditioner was installed by persons
without special skills,normal operations would not be ensured, even the personaland estate safetywould be affected
How to install indoor unit
The user's installation site should be provided with regular power supply in conformity with that indicated in nameplate of the air conditioner, and its voltage should be within a range 90
% 110 % of the rated voltage value.
Power circuit should be equipped with protector, such as electricity leakage protector or air switch, which should possess a capacity greater than 1.5 times the maximum current value
of the air conditioner.
Never fail to adopt personal circuit and effectively-grounded socket compatible with the attached plug of the air conditioner. The attached plug is equipped with grounding pin, and it
must not be modified as desired.
Please adopt the fuse or circuit breaker prescribed in Installation Instructions.
Only qualified electrician is allowed to carry out wiring tasks strictly according to electric safety requirements.
Do ensure good earth of air conditioner, in other words, the main power switch of air conditioner must be connected to reliable ground wire
The air conditionershould be installedsecurely; otherwise poorinstallation may leadto abnormal noisesand vibration.
Outdoor unit should beinstalled at a spotensuring that its airoutlet noises and hotexhaust will not violateyour neighbors.
INDOOR UNIT INSTALLATION
Installation method forindoor unit
1.Pendant installation of indoor unit
Installation mode of indoor unit must ensure minimum length of system pipeline and air conduit, therefore the Indoor unit should be installed at medium position of a suite.
Ensure adequate strength of the top suspension rod so as to withstand weight of the unit. Determine the position of suspension rod, align it to pendant-mounting hole in the unit, and then
tighten it (for position of suspension rod, see outline dimensional drawing for the unit)
Check the installation levelness of the unit, and set the drainage slope according to dimensions listed in figure below (Gradient greater than 1/100)

2. How to mount outlet pipe
Generally, we have two types of outlet pipe available, i.e. rectangular or round ones.
Rectangular air conduit can be directly connected to air outlet of indoor unit by rivets. For outlet dimensions, see outline drawing of the unit.
Round air conduit should be connected to a piece of transitional air conduit before it is connected to air outlet of indoor unit, the other end of it can be separately connected to air conduit
window or connected to air conduit window after air flow diversion, and the total length should not be over 6m. As shown in figure below, air speeds at all air outlets should be set to basically
consistent so as to meet the room air-conditioning requirements.

3. Installation method for return air pipe
In case sidewise air intake is adopted, return air pipe should be fabricated and rivet-connected to return air orifice, and the other end of it
should be connected to return air window.
In case of underside air intake, purchase or fabricate a section of pleated canvas air conduit serving as transition joint for return air orifice and
return air window. in this way, it can be freely adjusted according to height of indoor ceiling board; in addition, during operation of the unit , canvas
air conduit may avoid vibration of ceiling board, as shown in figure below.

4. Tips for installation of return air pipe and outlet pipe
To minimize energy loss occurring in transmission process and condensed water during heating operation, return air pipe and outlet pipe should
be equipped with heat-insulating layer as shown in the figure.
Return air pipe and outlet pipe should be fixed to floor precast slabs by iron stand; in addition, all ports of the air conduit should be tightly sealed
by gasket cement, and it is advisable that the edge clearance of return air pipe should be 150mm at least.
Drain pipe for condensed water should be installed with minimum gradient of 1 , and the drain pipe should be insulated with heat-preserving
pipe casing as well.
