3. SELECTING INSTALLATION SITE
Consider the following requirements when choosing the installation location and obtain the cus-
tomer’s consent:
•
The location must be able to withstand the weight of the BS unit.
•
The location must allow reliable draining.
•
The location must allow inspection holes to be installed on the control box side. (A separate opening is
necessary when lowering the product.)
•
There must be adequate space in which to perform installation and service work (
Refer to Fig. 1
).
•
The length of pipe to the indoor unit and outdoor unit must be less than or equal to the permissible pipe
length (as listed in the installation manual that came with the outdoor unit).
•
The sound of refrigerant being pumped through the pipes must not be a problem. (Never install above the
ceiling of an occupied room.)

WARNING
Securely install the unit at a location that is capable of withstanding its weight.
Inadequate strength may cause the indoor unit to fall, resulting in bodily injury.
CAUTION
•
Leave enough space to perform maintenance on the drain pan and control box.
•
To prevent video and audio interference, install the BS unit as well as associated power wiring and signal
transmission lines at least 1 m away from TVs and radios.
However, depending on the reception, interference may result even if a minimum distance of 1 m is main-
tained.
