2-4 NOTE TO THE INSTALLER
• Read this manual carefully to ensure correct installation. Be sure to instruct the customer how to operate
the system showing him/her the enclosed operation manual.
• Explain to the customer what system is installed on the site and be sure to fill in what is required in the col-
umn shown on "WHAT TO DO BEFORE OPERATION" of the operation manual.
3. SELECTING INSTALLATION SITE
(1) Select an installation site where the following conditions are fulfilled and that meets your cus-
tomer's approval.
• 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 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
surroundings easier maintenance and service.
• Where piping between indoor and outdoor units is possible within the allowable limit. (Refer to the instal-
lation manual for the outdoor unit.)
• Keep the indoor and outdoor units, power cable and transmission wiring, at least 1 m from TVs and
radios, to prevent distorted pictures and static. (Depending on the type and source of the electrical
waves, static may be heard even when more than 1 m away.)
