1. PRECAUTIONS
Ensure that all Local, National and International regulations
are satisfied.
Read this ”PRECAUTIONS ” carefully before Installation.
The precautions described below include the important items
regarding safety. Observe them without fail.
After the installation work, perform a trial operation to check
for any problem.
Follow the Owner’s Manual to explain how to use and maintain
the unit to the customer.
Turn off the main power supply switch (or breaker) before
maintenance the unit .
Ask the customer that the Installation Manual and the Owner’s
Manual should be kept together .
CAUTION
New Refrigerant Air Conditioner Installation
THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT(R410A)
WHICH DOES NOT DESTROY OZONE LAYER.
The characteristics of R410A refrigerant are; Hydrophilic, oxid-
izing membrane or oil, and its pressure is approx.1.6 times high-
er than that of refrigerant R22.Accompanied with the new refrig-
erant, refrigerating oil has also been changed ,Therefore, during
installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating
oil, the sizes of connecting sections of charging port of the
main unit and installation tools are charged from those for the
conventional refrigerant.
Accordingly the exclusive tools are required for the new
refrigerant (R410A): For connecting pipes, use new and clean
piping designed for R410A,and please care so that water or dust
does not enter. Moreover, do not use the existing piping because
there are problems with pressure-resistance force and impurity
in it.
CAUTION
Do not connect the Appliance from Main
Power Supply.
This unit must be connected to the main power supply by means
of a switch with a contact separation of at least 3 mm. The
installation fuse must be used for the power supply line of this
conditioner.
WARNING
If the supply cord is damaged, it must be replaced by the
manufacturer or its service agent or a similarly qualified person
in order to avoid a hazard.
An all-pole disconnection switch having a contact separation of
at least 3mm in all poles should be connected in fixed wiring.
The appliance shall be installed in accordance with
national
wiring regulations.
The temperature of refrigerant circuit will be high, please keep
the interconnection cable away from the copper tube.
An all-pole disconnection device which has at least 3mm
separation distance in all pole and a residual current device(RCD)
with the rating of above 10mA shall be incorporated in the fixed
wiring according to the national rule.
The power cord type designation is H05RN-R/H07RN-F or above.
Ask an authorized dealer or qualified installation professional to
install/maintain the air conditioner.
Inappropriate installation may result in water leakage,electric shock or
fire.
Turn off the main power supply switch or breaker before
attempting any electrical work.
Make sure all power switches are off.Failure to do so may cause
electric shock.
Connect the connecting cable correctly.
If the connecting cable is connected in a wrong way, electric parts may
be damaged.
When moving the air conditioner for the installation into another
place, be very careful not to enter any gaseous matter other than
the specified refrigerant into the refrigeration cycle.
If air or any other has is mixed in refrigerant, the gas pressure in the
refrigeration cycle becomes abnormally high and it may resultingly
causes pipe burst and injuries on persons.
Do not modify this unit by removing any of the safety guards or
by by-passing any of the safety interlock switches.
Exposure of unit to water or other moisture before installation
may cause a short-circuit of electrical parts.
Do not store it in a wet basement or expose to rain or water.
After unpacking the unit, examine it carefully if there are possible
damage.
Do not install in a place that might increase the vibration of the
unit.
To avoid personal injury (with sharp edges), be careful when
handling parts.
Perform installation work properly according to the Installation
Manual.
Inappropriate installation may result in water leakage, electric shock
or fire.
When the air conditioner is installed in a small room, provide
appropriate measures to ensure that the concentration of
refrigerant leakage occur in the room does not exceed the critical
level.
Install the air conditioner securely in a location where the
base can sustain the weight adequately. Perform the specified
installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur
due to the falling unit.
If refrigerant gas has leaked during the installation work,
ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas
may generate.
After the installation work, confirm that refrigerant gas doer not
leak.
If refeigerant gas leaks into the room and flows near a fire source,
such as a cooking range, noxious gas might generate.
Electrical work must be performed by a qualified electrician
in accordance with the Installation Manual. Make sure the air
conditioner uses an exclusive power supply.
