(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 carton box for installation.
Refer to it to check for points requiring reinforcing.)
4. PREPARATIONS BEFORE INSTALLATION
(1) Confirm the positional relationship between the unit
and suspension bolts. (Refer to Fig. 2)
• Install the inspection opening on the control box side where
maintenance and inspection of the control box and drain
pump are easy. Install the inspection opening also in the
lower part of the unit.
(length: mm)
(2) Make sure the range of the unit’s external static
pressure is not exceeded.
(See the technical documentation for the range of the
external static pressure setting.)

3. SELECTING INSTALLATION SITE
CAUTION
•
When moving the unit during or after unpacking, make sure
to lift it by holding its lifting lugs. Do not exert any pressure on
other parts, especially the refrigerant piping, drain piping and
flange parts.
•
If you think the humidity inside the ceiling might exceed
30°C and RH80%, reinforce the insulation on the unit body.
Use glass wool or polyethylene foam as insulation so that
it is no thicker than 10 mm and fits inside the ceiling
opening.
(1) Select an installation site where the following conditions
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 there is no risk of flammable gas leakage.
• Where sufficient clearance for maintenance and service
can be ensured.
(Refer to Fig. 1)
• Where piping between indoor and outdoor units is
possible within the allowable limit. (Refer to the installation
manual for the outdoor unit.)
• *H1 dimension means the minimum height of the unit.
•
Select the *H1, *H2 dimension such that a downward
slope of at least 1/100 is ensured as indicated in
“
7. DRAIN PIPING WORK ”.
•
The maintenance space marked with “ * ” is required when
the installation box for adaptor PC board (KRP1BA101)
sold separately is used.
[ PRECAUTION ]
• Install the indoor and outdoor units, power supply wiring
and connecting wires at least 1 m away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 m may not
be sufficient enough to eliminate the noise.)
•
If installing the wireless kit in a room with electronic
fluorescent lighting (inverter or rapid start type), the
remote controller’s transmission distance may be
shortened. Indoor units should be installed as far away
from fluorescent lighting as possible.
