Warning
!
Entrusted Installation
Installation of the machine should
be entrusted to certified person of
after service. Unauthorized install-
ation may cause water leakage,
electric shock or fire hazard for
improper operation.
!
To prevent leakage of refrigerant,
let certified person of after service
do it.
Leakage of refrigerant over certain
consistence may result in shortage
of oxygen. Enough precautions
MUST be done to avoid oxygen
shortage in case of refrigerant lea-
king if the room where the air-
conditioner is installed is small.
!
The power supply must be fitted with
earth line to ensure valid earthing of
the air-conditioner. No or incomplete
earthing connection may cause the
!
risk of electric shock.
Test run
After indoor units are installed,all
cassettes hinded models should be
tested.when the units are confirmed
to be normal,other fitments can be
installed.

Installation Procedure
Hose
Drain pipe size: ÿ19.05mm 2 (3/4") PVC pipe
The hose is used for adjusting the off-center and angle of the rigid PVC pipe.
Directly stretch the hose to install without making any deformation.
The soft end of the hose must be fastened with a hose clamp.
Please apply the hose on horizontal part
Insulation treatment:
Wrap the hose and its clamp until to the
indoor unit without any clearance with
insulating material, as shown in the figure.
Drain confirmation
During trial run, check that there is no leakage at the pipe connection part during water
draining even in winter.
Allowable pipe length and drop
These parameters differ according to the outdoor unit. See the instruction manual attached
with the outdoor unit for details.
Supplementary refrigerant
The refrigerant supplementation shall be as specified in the installation instructions
attached with the outdoor unit. The added refrigerant shall be R407C.
The adding procedure shall be aided with a measuring meter
for a specified amount of supplemented refrigerant
Requirement
Overfilling or underfilling of refrigerant will cause compressor
fault. The amount of the added refrigerant shall be as specified
in the instructions.
Connection of refrigerant pipe
Conduct flared connection work to connect all refrigerant pipes.
Pipe cutting and expanding
If the pipe is too long or the flare is damaged, it needs to be cut or expanded.
