For inspection and maintenance
When you change your address or the installation place
Electric work
Confirm the following items for safe and comfortable use of air conditioner.
The installation work is to be burden on the sales dealer, and do not conduct it by yourself.
Installation place
Avoid installing the air conditioner
near the place where possibility of
inflammable gas leakage exists.
Install the unit at well ventilated
place.
Install the air conditioner firmly on
the foundation that can fully support
the weight of the unit.
If not, it may cause vibration or noise.
If some obstacle exist, it may cause
capacity reduction or noise increase.
Explosion (Ignition) may occur.
Select the place so as not to annoy
neighbor with the hot air or noise.
Snow protection work is necessary
where outdoor unit is blocked up
by snow.
It is advisable not to install the air con-
ditioner at the following special place.
It may cause malfunction, consult the
sales dealer when you have to install
the unit on such a place.
The place where corrosive gas generates
(Hot spring area etc.)
The place where salt breeze blows
(Seaside etc.)
The place where dense soot smoke exists
The place where humidity is extraordina-
rily high
The place where near the machine which
radiates the electromagnetic wave
The place where voltage variation is con-
siderably large
For details consult your sales dealer.
The electric work must be burden on the authorized engineer with qualification for electric work and
grounding work, and the work must be conducted in accordance with electric equipment technical standard.
The power source for the unit is to be of exclusive use.
An earth leakage breaker should be installed.(This is necessary to prevent electric shock.)
The unit must be grounded.
Special technology is required for removal or reinstallation of air conditioner, consult the sales dealer.
Besides, construction expense is charged for removal or reinstallation.
The capacity of air conditioner will decrease by contamination of inside of unit when it is used for about
three years although depending upon the circumstances under which it is used, and so in addition to the
usual maintenance service, special inspection/maintenance service is necessary. It is recommended to
make a maintenance contract (charged) by consulting your sales dealer.

- Once the fan controller has trouble this linker can perform emergency assistant control when this linker is connected to the linker from the pcb it can operate with total load 20
- The example of the method of choosing capacity number 20
- The figure circled in figure ii indicate the capacity number of fan controller the non listed capacity number may exceed the permitted operation capacity range so it is impossible to operate 20
- The operation method of fan controller 20
- Through the fan controller switch in the electric box the air volume of this unit can be continuously adjusted it is unnecessary to adjust air volume through the duct side wind level unit outside static adjustment the air volume set should be in the operation air volume range figure i shows the position of fan controller in the electric box and operation method 20
- When delivering from factory the capacity number of fan controller is set at ì no î 20
- When operating the fan controller it is possible to touch the electric charging part so do cut off the power supply 20
- When this linker is connected to the linker from the pcb through the fan speed adjustment panel to adjust speed 20

- Refrigerant pipe 21
- The air side pipe liquid side pipe must be faithfully heat insulated if no heat insulation it may cause water leakage 21
- The outdoor unit has been charged with refrigerant when connect the pipe to the unit or dismantling the pipe from the unit please follow the figure shown use spanner and torque spanner together when connect cone nut the inner side and outside of cone nut should paste with refrigerant oil use hand to twist 3 4 rings then fasten with spanner referring to table i to confirm the fasten torque too tight may damage nut leading to leakage check if the connection pipe leaks then do heat insulation treatment as below figure shown only use seal cushion to bind the joint part of air pipe and heat insulation parts 21
