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, oxidizing membrane or oil, and its pressure is approx.1.6 times
higher than that of refrigerant R22.Accompanied with the new refrigerant,
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 directly.
WARNING
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. The appliance shall be installed in accordance with national
wiring regulations. If the supply cord is damaged, it must be replaced by the
manufacture 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
dimensions of the space necessary for correct installation of the appliance
including the minimum permissible distances in order to avoid a hazard.

4.7 Remove Dirt or Water in the Piping
Make sure there is no any dirt or water before connectiong the piping to the
outdoor units. Wash the piping with high pressure nitrogen, never use
refrigerant of outdoor unit.
4.8 Airtight Test
Charge pressured nitrogen after connecting indoor/outdoor unit piping to do
airtight test.
CAUTION
1. Pressured nitrogen [ 4.3MPa (44kg/cm 2) for R410A] should be used in the
airtight test. 2. Tighten high pressure/low pressure valves before
applying pressured nitrogen. 3. Apply pressure from air vent mouth on the
hight pressure/
low pressure valves. 4. The high pressure/low pressure valves are closed when
applying pressured nitrogen. 5. The airtight test should never use any oxygen,
flammable gas or poisonous gas.
4.9 Air Purge with Vacuum Pump
Using vacuum pump to do the vacuum,never using refrigerant to expel the air.
Vacuuming should be done from both liquid side and gas side simultaneously.
4.10 Refrigerant Amount to be Added
Calculate the added refrigerant according to the diameter and the length of
the liquid side pipe of the outdoor unit/indoor unit connection.

5. ELECTRICAL WIRING
CAUTION
Design a dedicated power supply for the indoor unit and outdoor unit. If the
power supply uses a branch loop, install an electricity leakage protector and
a manual switch.
The power supply, electric leakage protectors, and manual switches of the
indoor units that connect to the same outdoor unit must be universal. Use the
same loop for the indoor unit power connect to the same outdoor unit must be
universal. Use the same loop for the indoor unit power supplies in the same
system. Power on/off at the same time.
Incorporate the outdoor unit and indoor unit connection wiring system and
refrigerant pipe system for the same system.
To reduce interference, use a three-core shielded twisted pair as the outdoor
unit signal cable. Do not use a multi-core cable.
Complete wiring according to national electrical standards. Employ an
electrical engineer for wiring.

8. PRECAUTIONS ON REFRIGERANT LEAKAGE
This air conditioner(A/C) adopts inncouous and nonflammable refrigerant. The
locating room of the A/C should big engough that any refrigerant leakage is
unable to reach critical thickness. So certain esssential action can be taken
on time.
Critical thickness——the Max. thickness of Freon without any harm to person.
Refrigerant critical thickness: 0.44[kg/m3] for R410A.
Confirm the critical thickness through follow steps, and take necessary
actions.
1. Calculate the sum of the charge volume (A[kg]) Total Refrigerant volume of
10HP=factory refrigerant volume + superaddition
2. Calculate the indoor cubage (B[m3]) (as the minimum cubage.
3. Calculate the refrigerant thickness
