3. SELECTING INSTALLATION SITE
NOTE
•
If you think the humidity inside the ceiling might exceed 86°F and RH80%, reinforce the insulation on the
inter-unit piping.
•
Use glass wool or polyethylene foam as insulation so that it is no thinner than 3/8’’ and fits inside the ceiling
opening.
(1)
Select an installation site where the following conditions are satisfied and that meets with your customer’s
approval.
•
Where is resistible against weight of BS unit.
•
Where sufficient clearance for maintenance and service can be ensured.
•
Where the total piping length involving indoor unit and outdoor unit is below the allowable piping length.
(See installation manual attached to outdoor unit.)
•
Locations where there is no possibility of flammable gas leaking.
•
Locations where the wall is not significantly tilted.
•
Locations where an inspection hole (see figure below) can be installed.

(Sight opening must be of above size and provided in front of electric parts box.)
NOTE
1.
Leave 4’’ of service space below the electric parts box.
If this is not possible, open a service hole in the location indicated in the
figure below.
2.
Make sure the power, branch, and remote control wiring of the indoor, out-
door, and BS units are at least 40’’ away from radios and televisions. This
is to prevent interference with picture and sound reception.
(Interference may occur even at 40’’ away depending on the reception
quality.)
(2)
Use suspension bolts for installation. Check if the location for the installation is strong enough to support
the weight of the unit, reinforce it if necessary, and install using suspention bolts.
