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 wall 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 wall 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 wall/floor is strong enough to bear the indoor
unit weight.
•
Where the floor 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.
•
Where piping between indoor and outdoor units is possi-
ble within the allowable limit. (Refer to the installation
manual for the outdoor unit.)
•
The equipment is not intended for use in a potentially
explosive atmosphere.
[ 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 wall/floor is strong enough to support the weight of
the unit or not. If there is a risk, reinforce the wall/floor
before installing the unit.
To avoid contact with the fan, the following precaution action must be
taken:
-
Install the unit with ducting and grill which can only be
removed with the aid of tooling. It shall be installed so that
it gives adequate protection against touching the fan. If a
maintenance panel exists in the ducting, it shall only be
possible to remove the panel by the aid of tooling to avoid
contact with the fan. The protection shall be according to
relevant European and local legislation. There are no
restrictions concerning the installation height.
4. PREPARATIONS BEFORE INSTALLATION
(1) Make sure the range of the unit’s external static pres-
sure is not exceeded.
(See the technical documentation for the range of the
external static pressure setting.)
(2) In case of front suction:
(1) Remove the protection net.
(2) Remove the chamber lid. (7 locations)
(3) Remove one leg on the opposite side of the el. compo
(for instruction, see page 4, “Removing the legs”).
(4) Reattach the removed chamber lid in the orientation
shown in picture 2 below. (7 locations)
(5) Attach the protection net to the front side.
(6) Reattach the leg if necessary.
(7) Attach the air filter (accessory) in the manner shown in
the diagram.
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.
