●
Read the safety precautions carefully before operating the unit.
●
The contents of this section are vital to ensure safety. Please pay special attention to the following sign.
WARNING ........ Incorrect methods of installation may cause death or serious injury.
CAUTION ......... Improper installation may result in serious consequence.
Make sure to connect earth wire.
This sign in the gures indicates prohibition.
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.
Tools Needed For Installation Work

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 cables which are of cially
approved in your country. Be sure to use the speci ed circuit. A short circuit and re may
occur due to the use of low quality wire or improper work.
●
Be sure to use the speci 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 re.
●
Please use the speci ed components for installation work. Otherwise, the units may collapse
or water leakage, electric shock, re or stronger vibration may occur.
●
Be sure to use the speci ed piping set for R32. Otherwise, this may result in broken copper
pipes or faults.
●
When installing or transferring an air conditioner to another location, make sure that air
other than the speci ed refrigerant(R32) does not enter the refrigeration cycle. If other air
should enter, the pressure level of the refrigeration cycle may increase abnormally which
could result in a rupture and injury.
●
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.
●
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.
●
When nishing the refrigerant collection (pumping down), stop the compressor and then
remove the coolant pipe. If you remove the refrigerant pipe while the compressor is operating
and the service valve is released, air is sucked and a pressure in the freezing cycle system
will build up steeply, causing an explosion or injury.
●
When installing the unit, be sure to install the refrigerant pipe before starting the compressor.
If the refrigerant pipe is not installed and the compressor is operated with the service
valve released, air is sucked and the pressure level of the refrigeration cycle may increase
abnormally which could result in a rupture and injury.
●
The electric cables should neither be reworked nor added. Make sure to use an exclusive
circuit breaker. Otherwise re or electric shock might occur by connection failure, isolation
failure or over current.
●
Make sure to connect cables to terminal properly and terminal cover should close rmly.
Otherwise, over heating at terminal contact, re or electric shock might occur.
●
Make sure that there is no dust on any connected points of electric cables and x rmly.
Otherwise, re or electric shock might occur.
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 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 ammable gas. The outdoor unit may
catch re if ammable gas leaks around it.
●
Please ensure smooth ow of water when installing the
drain hose. Improper installing may wet your furniture.
●
An IEC approved power cord should be used. Power cord
type: NYM.
WARNING
●
The unit should be mounted at stable, non-vibratory location which can provide full support to the unit.
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.
●
No nearby leakage risk of 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 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 2300 mm or more from the oor.
●
The distance from the air outlet to the re alarm must be at least 1500mm and there must be no re alarm in the front
direction of the indoor unit.
