c. Points for explanation about operations

4. Note to the installer

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

3. SELECTING INSTALLATION SITE

Please attach additional thermal insulation material to the unit body when it is believed that the relative humid-
ity in the ceiling exceeds 80%. Use glass wool, polyethylene foam, or similar with a thickness of 10 mm or 
more as thermal insulation material.

1. Select an installation site where the following conditions are fulfilled and that meets 

your customer’s approval.

In the upper space (including the back of the ceiling) 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.

Where the ceiling is strong enough to bear the indoor unit weight.

Where the false ceiling is not noticeably on an incline.

Where sufficient clearance for maintenance and service can be ensured.

Where there is no risk of flammable gas leakage.

Where piping between indoor and outdoor units is possible within the allowable limit. (Refer to the 
installation manual for the outdoor unit.)

CAUTION

Keep indoor unit, outdoor unit, power supply wiring and transmission wiring at least 1 meter away from 

televisions and radios. This is to prevent image interference and noise in those electrical appliances.

(Noise may be generated depending on the conditions under which the electric wave is generated, 

even if 1 meter is kept.)

2. 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 installation. Refer to it to check for points requiring 
reinforcement.)

The items with

WARNING and

CAUTION marks in the operation 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 operation manual.
