FOR THE FOLLOWING ITEMS, TAKE SPECIAL 
CARE DURING CONSTRUCTION AND CHECK 
AFTER INSTALLATION IS FINISHED.

a. Items to be checked after completion of work

b. Items to be checked at time of delivery

Also review the “SAFETY CONSIDERATIONS”

c. Points for explanation about operations

2-4

NOTE TO THE INSTALLER

Be sure to instruct customers how to properly operate the 
unit (especially cleaning filters, operating different functions, 
and adjusting the temperature) by having them carry out 
operations themselves while looking at the manual.

3. SELECTING INSTALLATION SITE

(1) Select an installation site where the following condi-

tions are fulfilled and that meets your customer’s 
approval.

• In the upper space of the indoor unit where there is no 

possible dripping of water from the refrigerant pipe, drain 
pipe, water pipe, etc.

• Where optimum air distribution can be ensured.
• Where nothing blocks air passage.
• Where condensate can be properly drained.
• If supporting structural members are not strong enough 

to take the unit’s weight, the unit could fall out of place 
and cause serious injury.

• Where the false ceiling is not noticeably on an incline.
• Where there is no risk of flammable gas leakage.
• Where sufficient clearance for maintenance and service 

can be ensured. 

(Refer to Fig. 1)

If sufficient clearance could be ensured at*, leave a 
space of 200 mm or more between the unit and it’s sur-
roundings easier maintenance and service.

• Where piping between indoor and outdoor units is possi-

ble within the allowable limit. (Refer to the installation 
manual for the outdoor unit.)

CAUTION

• Install the indoor and outdoor units, power supply wiring and 

connecting wires at least 1 meter away from televisions or 
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may 
not be sufficient enough to eliminate the noise.)

(2) This indoor unit may be installed on ceilings up to 3.5 m 

in height. However, if the ceiling is higher than 2.7m, 
the remote control will have to be set locally. (Refer to  
“11. FIELD SETTING” on page 12)

(3) Use suspension bolts for installation. Check whether 

the ceiling is strong enough to support the weight of 
the unit or not. If there is a risk, reinforce the ceiling 
before installing the unit.

(Installation pitch is marked on the paper pattern for instal-
lation. Refer to it to check for points requiring reinforcing.)

Items to be checked

If not properly done, what is 
likely to occur

Check

Are the indoor and outdoor 
unit fixed firmly?

The units may drop, vibrate 
or make noise.

Is the gas leak test finished? 

It may result in insufficient 
cooling.

Is the unit fully insulated?

Condensate water may drip.

Dose drainage flow 
smoothly?

Condensate water may drip.

Dose the power supply volt-
age correspond to that 
shown on the name plate?

The unit may malfunction or 
the components burn out.

Are wiring and piping cor-
rect?

The unit may malfunction or 
the components burn out.

Is the unit safely grounded?

Dangerous at electric leak-
age.

Is wiring size according to 
specifications?

The unit may malfunction or 
the components burn out.

Is something blocking the air 
outlet or inlet of either the 
indoor or outdoor units?

It may result in insufficient 
cooling.

Are refrigerant piping length 
and additional refrigerant 
charge noted down?

The refrigerant charge in the 
system is not clear.

Items to be checked

Check

Did you explain about operations while showing the 
instruction manual to your customer?
Did you hand the instruction manual over to your cus-
tomer?

The items with  

  WARNING and  

  CAUTION marks 

in the instruction manual are the items pertaining to 
possibilities for bodily injury and material damage in 
addition to the general usage of the product. Accordingly, it 
is necessary that you make a full explanation about the 
described contents and also ask your customers to read the 
instruction manual.
