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 10mm and fits inside the ceiling open-
ing.
(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 possi-
ble 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 fluo-
rescent lighting (inverter or rapid start type), the remote
controller’s transmission distance may be shortened.
Indoor units should be installed as far away from fluores-
cent lighting as possible.
(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 installa-
tion. Refer to it to check for points requiring reinforcing.)
Is something blocking the air
outlet or inlet of either the
indoor or outdoor units?
It may result in insufficient
cooling.
Are refrigerant piping length
and additional refrigerant
charge noted down?
The refrigerant charge in the
system is not clear.
Items to be checked Check
Did you explain about operations while showing the
operation manual to your customer?
Did you hand the operation manual and warranty over to
your customer?
Did you explain about the way of maintaining and cleaning
local procurements (air filter, grille (both air outlet and suc-
tion grille), etc.) to your customer?
Did you hand manuals of local procurements (in case
equipped) over to your customer?
The items with WARNING and CAUTION marks in
the operation manual are the items pertaining to
possibilities for bodily injury and material damage in
addition to the general usage of the product. Accordingly, it
is necessary that you make a full explanation about the
described contents and also ask your customers to read the
operation manual.
