WARNING
•Please request your sales agent or qualified technician to install your unit. Water leakage, short circuit or fire may occur if you do the
installation work yourself.
•Please observe the installation stated in the installation manual during the process of installation. Improper installation may cause
water leakage, electric shock and fire.
•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 approved official in your country. Be sure to use the specified circuit. A short circuit and
fire may occur due to the use of low quality wire or improper work.
•Be sure to use the specified 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 fire.
•Please use the specified components for installation work. Otherwise, the unit may collapse or water leakage, electric shock, fire or
stronger vibration may occur.
•Be sure to use the specified 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 specified 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 fire, a poisonous gas may
occur.

•Unauthorized modifications to the air conditioner may be dangerous. If a breakdown occurs please call a qualified air conditioner
technician or electrician. Improper repairs may result in water leakage, electric shock and fire, 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 finishing 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.
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 flammable gas. The outdoor unit may catch fire
if flammable gas leaks around it.
•Please ensure smooth flow of water when installing the drain hose. Improper installing may wet your funiture.
•An IEC approved power cord should be used. Power cord type: NYM.
TINU ROODNI
WARNING
THE CHOICE OF MOUNTING SITE (Plea no tse te he following m rs obtatte and ain pe iorm ssi n from customer before i tans ll tioa n.)
•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 ar e
specified in figure 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 an d
t v n.ele isio
•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.
TINU ROODTUO
WARNING
•The Outdoor unit must be mounted at a location which can
support heavy weight. Otherwise, noise and vibration will
increase.
CAUTION
•
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
specified in figure below. At least three 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 flammable gas,
steam, oil and smoke.
•The location must be convenient for water drainage.
•Place the Outdoor unit and its connecting cord at least 1 m
away from the antenna or signal line of television, radio or
telephone. This is to avoid noise interference.

1 Installation of Hanger, Wall Penetration and Installation of Protection Pipe
CAUTION
•The draining of the water container inside the Indoor unit can be done from the left.
Therefore the hanger must be fixed horizontally or slightly tilted towards the side of
drain hose. Otherwise, condensed water may overflow the water container.
•Drill ø65mm hole on wall which a 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.
•Please ensure smooth flow of wate r
when installing the drain hose. Improper
installing may wet your funiture.
•An IEC approved power cord should be
used. Power cord type: NYM.
WARNING
Be sure that the wire is not
in contact with any metal in
the wall. Please use th e
protection pipe as wir e
passing through the hollow
part of the wall so as to
prevent the possibility of
damaged by mouse.

•
Exchange the location of drain hose and drain cap while installing the pipe from the left side as
shown in below. Be sure to plug in the drain hose until the insulating material folds upon itself.
Cutting Low Cover bush
•While installing the pipe from the right, left or
bottom side, use a knife to cut openings as
shown in figure. Then smoothen the edges of
openings with a file.
CAUTION
•The rubber strap used for fixing the insulator
should not be tied with great force. Otherwise,
this will damage heat insulation and causes
water condensation.
•Please pull the lower part of the Indoor unit
outwards to check if the unit is hooked onto
the hanger. Improper installation may cause
vibration and noise.
•Transform the piping while holding down the
lower portion of pipe-support by hand.
