INSTALLATION
● Flare nut must use a torque wrench without fail. Tighten with the specifi ed tightening torque. If the fl are nut is tightened
too much, after a long period of time, the fl are nut breaks, Gas leakage, stagnation, touching fi re, rarely cause ignition.
MANUAL
● Sharp bending of the pipe use the polyethylene rod, bend not crushed the pipe. Gas leakage from the crushed part,
stagnation, touching fi re, rarely cause ignition.
●
Please request your sales agent or qualifi ed technician to install your unit. Water leakage, short circuit or fi 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 fi re.
Home
● 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
Ducted
when dealing with the electrical work. Use cables which are offi cially approved in your country. Be sure to use the
specifi ed circuit. A short circuit and fi re may occur due to the use of low quality wire or improper work.
●
Be sure to use the specifi ed cables 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 to prevent the external force is being applied
to the connection section of the terminal base. Improper insertion and loose contact may cause over-heating and fi re.
SPLIT TYPE AIR CONDITIONER
●
Please use the specifi ed components for installation work. Otherwise, the units may collapse or water leakage, electric
shock, fi re or stronger vibration may occur.
INDOOR UNIT
●
Be sure to use the specifi ed piping set for R32. Otherwise, this may result in broken copper pipes or faults.
RAD-GJ07QHAA ● When installing or transferring an air conditioner to another location, make sure that air other than the specifi ed
refrigerant(R32) does not enter the refrigeration cycle. If other air should enter, the pressure level of the refrigeration

● Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with fi 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

● Be sure to connect the earth line from the power supply wire to the outdoor unit and between the outdoor and indoor
unit. Do not connect the earth line to the gas tube, water pipe, lighting rod or the earth line of the telephone unit.
Improper earthing may cause electric shocks.

may cause death or serious injury.
Make sure to connect earth line.
Be sure that the unit operates in proper condition after installation. Explain to customer the proper operation and maintenance of
the unit as described in the user's guide. Ask a customer to keep this installation manual together with the instruction manual.

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
No nearby heat source and no obstruction near the air
outlet is allowed.
The clearance distances from top, right and left are specifi ed
in fi gure below.
The location must be convenient for water drainage and
pipe connection with the Outdoor unit.
No nearby leakage risk of fl ammable gas, and no nearby
source of vapor or oil smoke.
To avoid interference from noise, please place the unit and
its remote controller at least 3.28ft(1m) from the radio and
television.
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 should be at least 98-14/32"
(2500mm) or more from the fl oor.
The distance from the air outlet to the fi re alarm must
be at least 59-2/32" (1500mm) and there must be no fi re
alarm in the front direction of the indoor unit.
Do not install the indoor unit in a machine shop, kitchen
and laundry rooms when vapor from oil or its mist fl ows to
the indoor unit. The oil will deposit on the heat exchanger,
thereby reducing the indoor unit performance and may
deform and in the worst case, break the plastic parts of
the indoor unit.

Be sure to completely
seal any gap with putty.
The connecting pipe,
irrespective of the size,
should all be insulated with
insulation pipe and then
wrapped with vinyl tape. (The
insulator will deteriorate if it
is not wrapped with tape).
Drain pipe
Must be installed separately.
Insulate indoor part of pipe to
prevent condensation.
"Height difference" and "Piping length" of Indoor and Outdoor unit are different by Outdoor unit.
Please refer to the installation manual in Outdoor unit.

The Choice of Mounting Site
! CAUTION
● A circuit breaker must be installed in the house
distribution box for the direct connected power
supply cables to the outdoor unit. In case of other
installations a main switch with a contact gap or
more than 4/32" (3mm) has to be installed. Without
a circuit breaker, the danger of electric shock exists.
Do not install the unit near a location
●
where there is flammable gas. The
outdoor unit may catch fi re if fl ammable
gas leaks around it.
Please ensure smooth fl ow of water when installing
●
the drain hose. Improper installing may wet your
furniture.
Piping shall be suitable supported with a maximum
●
spacing of 3-9/32' (1m) between the supports.
Please ensure fi eld selected electrical components

(switches,wires,etc) are following approved local
regulation requirements.
● This air conditioner is an appliance that should not be accessible to the general public.
● One ducted unit shall be supplying to one room.
