3. SELECTING INSTALLATION SITE
CAUTION
• When moving the unit while removing it from the packing
case, be sure to lift it by the four hanger brackets. Avoid put-
ting any pressure on other parts especially the refrigerant
piping.
• If you think the humidity inside the ceiling might exceed 86°F
and RH80%, reinforce the insulation on the unit body.
Use glass wool or polyethylene foam as insulation so that the
thickness is more than 1/2 in. and fits inside the ceiling open-
ing.
(1) Select an installation site where the following condi-
tions are fulfilled and that meets with your customer’s
approval.
• 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 ser-
vice can be ensured. (Refer to Fig. 1)
• Where piping between indoor and outdoor units is pos-
sible within the allowable limit. Refer to the installation
manual for the outdoor unit.
• Select the *H dimension such that a downward slope of
at least 1/100 is ensured as indicated in Section 7.
DRAIN PIPING WORK.
• The maintenance space marked with an asterisk is
required when the installation box for adaptor PC board
(KRP1B101) sold separately is used.
[ PRECAUTION ]
• Install the indoor and outdoor units, power supply wiring
and connecting wires at least 3.3 feet away from tele-
visions or radios in order to prevent image interference
or noise. Depending on the radio waves, a distance of
3.3 feet may not be sufficient enough to eliminate the
noise.
• If installing the wireless kit in a room with electronic flu-
orescent lighting, the remote controller’s transmission
distance may be shortened. Indoor units should be
installed as far away from fluorescent lighting as possi-
ble.
DANGER
• Do not install unit in an area where flammable materials are
present due to the risk explosion resulting in serious injury
or death.
