WARNING
!
CAUTION
!
●
Please request your sales agent or quali ed technician to install your unit. Water leakage, short circuit or re may occur if
you do the installation work yourself.
●
Please observe the instructions stated in the installation manual during the process of installation. Improper installation may
cause water leakage, electric shock and re.
●
Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not,
the units may collapse and impose danger.
●
Observe the rules and regulations of the electrical installation and the methods described in the installation manual when
dealing with the electrical work. Use power cables approved by the authorities of your country.
●
Be sure to use the speci ed wire for connecting the indoor and outdoor units. Please ensure that the connections are tight
after the conductors of the wire are inserted into the terminals. Improper insertion and loose contact may cause over-heating
and re.
●
Please use the speci ed components for installation work. Otherwise, the units may collapse or water leakage, electric shock
and re may occur.
●
Be sure to use the speci ed piping set for R-410A. Otherwise, this may result in broken copper pipes or faults.
●
When installing or removing an air conditioner, only speci ed refrigerant (R410A) shall be allowed, do not allow air or moisture
to remain in the refrigeration cycle. Otherwise, pressure in the refrigeration cycle may become abnormally high so that a
rupture may be caused.
●
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with re, a poisonous
gas may occur.
●
After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas
leaks into the room, coming into contact with re in the fan-driven heater, space heater, etc., a poisonous gas may occur.
●
Unauthorized modi cations to the air conditioner may be dangerous. If a breakdown occurs please call a quali ed air
conditioner technician or electrician. Improper repairs may result in water leakage, electric shock and re, etc.
FOR SERVICE PERSONNEL ONLY
The Choice of Mounting Site
(Please note the following matters and obtain permission from customer before installation).
WARNING
!
●
The unit should be mounted at stable, non-vibratory location
which can provide full support to the unit.
WARNING
!
●
The Outdoor unit must be mounted at a location which can support
heavy weight. Otherwise, noise and vibration will increase.
CAUTION
!
●
No nearby heat source and no obstruction near the air outlet is
allowed.
●
The clearance distances from top, right and left are speci ed in
gure below.
●
The location must be convenient for water drainage and pipe
connection with the Outdoor unit.
●
To avoid interference from noise please place the unit and its
remote controller at least 1m from the radio, television and inverter
type uorescent lamp.
●
To avoid any error in signal transmission from the remote controller,
please put the controller far away from high-frequency machines
and high-power wireless systems.
●
The installation height of indoor unit must be 2.3m or more.
CAUTION
!
●
Do not expose the unit under direct sunshine or rain. Besides,
ventilation must be good and clear of obstruction.
●
The air blown out of the unit should not point directly to animals
or plants.
●
The clearances of the unit from top, left, right and front are
speci ed in gure below. At least 3 of the above sides must be
open air.
●
Be sure that the hot air blown out of the unit and noise do not
disturb the neighbourhood.
●
Do not install at a location where there is ammable gas, steam,
oil and smoke.
●
The location must be convenient for water drainage.
●
Place the Outdoor unit and its connecting cord at least 1m away
from the antenna or signal line of television, radio or telephone.
This is to avoid noise interference.
●
Do not install outdoor unit facing strong wind direction. It may
damage the fan motor.

allowed, namely, horizontally
perpendicular to the unit,
vertically down from right,
horizontally out from right and
horizontally out to left.
Don’t form the piping downward
at the left of the unit.
●
The difference in height
between the indoor and
outdoor unit should be
kept max 10m.
●
The connecting pipe,
no matter big or small,
should all be insulated
with insulation pipe and
then wrapped with vinyl
tape. (The insulator will
deteriorate if it is not
wrapped with tape).
The connection of insulated
drain hose.
Please use insulated drain
hose for the indoor piping
(commercial product).
The indoor piping should
be insulated with the
enclosed insulation pipe. (If
the insulator is insuf cient,
please use commersial
products).
Be sure to
completely
seal any
gap with
putty.
Installation of Mounting Plate, Wall Penetration and Installation of Protection Pipe
1
CAUTION
!
●
The draining of the water container inside the indoor unit can be done from the left.
Therefore the mounting plate must be xed horizontally or slightly tilted towards the
side of drain hose. Otherwise, condensed water may over ow the water container.
Direct Mounting On The Wall
●
Please use hidden beams in the wall to hold the mounting plate.
Wall Penetration and Installation of Protection Pipe
●
Drill a ø 65mm hole on
wall which is slightly tilted
towards the outdoor side.
Drill the wall at a small
angle.
●
Cut the protection pipe
according to the wall
thickness.
●
Empty gap in the sleeve
of protection pipe should
be completely sealed with
putty to avoid dripping of
rain water into the room.

VERTICALLY DOWNWARD PIPING
Preparation
●
Connect connecting cord.
●
Pull out the pipe, connecting cord and drain hose.
Installation
●
The upper part of the Indoor unit is hanged on the mounting plate.
●
The projection at the lower part of the Indoor unit is hooked onto the mounting plate.
Please pull the lower part of
the Indoor unit outwards to
check if the unit is hooked
onto the mounting plate.
Improper installation may
cause vibration and noise.
!
CAUTION
HORIZONTAL PIPING
Preparation
Change of Drain Hose and Installation Procedures.
●
Exchange the location of drain hose and drain cap during horizontal piping as shown in
gure below. Be sure to plug in the drain hose until the insulating material folds upon
itself.
●
Please use pliers to pull out the drain cap.
(This is an easier way to remove the drain cap).
INSTALLATION OF REFRIGERATING PIPES AFTER CONNECTION
●
The refrigerating pipes should be adjusted to t
into the hole on the wall and then ready for further
connection.
●
The terminals of 2 connected pipes must be covered
with insulator used for terminal connection. Then the
pipes are wrapped with insulation pipe.
●
Connect the connecting cord after removing electrical
cover. (Refer to “CONNECTION OF POWER CORD”)
●
After adjustment, t the connecting cord and pipes
into the space available under the indoor unit. Use
holder to hold them tight.
!
CAUTION
●
The rubber strap used for
xing the insulator should
not be tied with great force.
Otherwise, this will damage
heat insulation and causes
water condensation.
●
Holder can be attached at the either of 2 places.
Please select the easier position.
THE CONNECTION OF REFRIGERATING PIPE DURING THE
INSTALLATION OF INDOOR UNIT
Preparation To Install Refrigerating Pipes
!
CAUTION
●
Please x in the plastic core
after aring to avoid plastic
chips entering the pipes.
CAUTION
!
You are free to choose the side (left or right) for the installation of drain
hose. Please ensure the smooth ow of condensed water of the Indoor
unit during installation. (Carelessness may result in water leakage.)
!
CAUTION
Be sure that the
drain hose is not
loosely connected
or bend.
Be sure that the wire is not
in contact with any metal
in the wall. Please use
the protection pipe as wire
passing through the hollow
part of the wall so as to
prevent the possibility of
damaged by mouse.
Unless it seals completely,
any air with high humidity
flows from outdoor and
any dew may drop.
!
WARNING
●
The refrigerating pipes and connecting cord
transform and are attached.
●
The end of the refrigerating pipes are at locations
marked with “
” symbol.

refrigerating pipe.
●
Connect the connecting cord after removing electrical cover.
(Refer to “Connection of Power Cord”)
●
After adjustment, the connecting cord and refrigerating pipes
are placed into the space available under the Indoor unit.
●
The projection of Indoor unit must hook to the mounting plate.
