TIPS FOR SAVING ENERGY
WARNING
!
Here are some tips that will help you minimize the power consumption
when you use the air conditioner. You can use your air conditioner
more efficiently by referring to the instructions below:
• Do not cool excessively indoors. This may be harmful for your
health and may consume more electricity.
• Block sunlight with blinds or curtains while you are operating the
air conditioner.
• Keep doors or windows closed tightly while you are operating the
air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Open windows regularly for ventilation as the indoor air quality
may deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

ALTERNATIVE REFRIGERANT R410A
The refrigerant R410A has the property of higher operating pressure in
comparison with R22.
Therefore, all materials have the characteristics of higher resisting
pressure than R22 ones and this characteristic should be also considered during the installation.
R410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone
depletion potential (ODP) of R410A is 0.
CAUTION
!
• The wall thickness of the piping should comply with the relevant
local and national regulations for the designed pressure 3.8MPa
• Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state.
If the refrigerant is charged in its gaseous state, its composition
changes and the system will not work properly.
• Do not place the refrigerant container under the direct rays of
the sun to prevent it from exploding.
• For high-pressure refrigerant, any unapproved pipe must not be
used.
• Do not heat pipes more than necessary to prevent them from
softening.
• Be careful not to install wrongly to minimize economic loss
because it is expensive in comparison with R22.
SELECT THE BEST LOCATION
Select space for installing outside unit , which will meet the following
conditions:
- With strength which bears weight of unit
- With space for air passage and service work
Don't install the unit at the space where generation, inflow, stagnation, and leak of combustible gas is expected.
- Avoid unit installation in a place where acidic solution and spray (sulfur) are often used.
- Location with no leakage of combustible gas
- Recommend the outside unit to be installed within 0~40°C.
- Location with installation or service work space (Refer to required
space)
- Do not use the outside unit under any special environment where oil,
steam and sulfuric gas exist.
- Install in a separate machine room not exposed to external air
Establish an anti-freeze plan for the water supply when the product is
stopped during the winter.
Install the product so that the noise from the machine room is not
transferred outsides
- The floor of the machine room must be water proof.
- Drainage must be installed in the machine room to process the water
drainage.
- Install a floor slope to make the drainage smooth.
- Avoid installing the outside unit in the location with following conditions.
- Location where corrosive gas such as acidic gas is generated.
(It may cause the refrigerant leakage by corrosion of the pipe.)
- Location where electromagnetic waves happen.
(It may cause the abnormal operation by control parts disorder.)
- Location to be able to leak the combustible gas
- Location with carbon fiber or combustible dust.
- Location with the combustible material like thinner or gasoline.
(It may cause a fire by leaking the gas near the product.)

WATER CONTROL INSTALLATION SPACE
Individual Installation Water control
During the installation of the unit, consider service, inlet, and outlet
acquire the minimum space as shown in the figures below.
: Service area
- Keep the water temperature between 10~45°C. Other it may cause
the breakdown.
Standard water supply temperature is 30°C for Cooling and 20°C for
heating.
- Properly control the water velocity. Otherwise it may cause the noise,
pipe vibration or pipe contraction, expansion according to the temperature. Use the same water pipe size connected with the product or
more.
- Refer to the water source pipe diameter and water velocity table
below. As the water velocity is fast, air bubble will increase.
Diameter (mm) Velocity range (m/s)
< 50 0.6 ~ 1.2
50 ~ 100 1.2 ~ 2.1
100 < 2.1 ~ 2.7
Collective / Continuous Installation
Space required for collective installation and continuous installation as
shown below considering passage for air and people.
: Service area
* In case of the water pipe passing side product, please make suffi-
cient service place to avoid occurring between water pipe and product side.
Two Layer Installation
Space required for two layer installation as shown below considering
passage for air and people.
: Service area
- Be careful of the water purity control. Otherwise it may cause the
breakdown due to water pipe corrosion.
(Refer to 'Standard Table for Water Purity Control')
- In case the water temperature is above 40°C, it is good to prevent the
corrosion by adding the anticorrosive agent.
- Install the pipe, valve and gauge sensor in the space where it is easy
to maintain. Install the water valve in the low position for drain, if required.
- Be careful not to let air in. If so, the water velocity will be unstable in
the circulation, pump efficiency will also decrease and may cause the
piping vibration. Therefore, install the air purge where it may generate
the air.
- Choose the following anti freezing methods. Otherwise, it will be dangerous for the pipe to break in the winter.
Circulate the water with the pump before dropping the temperature.
Keep the normal temperature by boiler.
When the cooling tower is not operated for a long time, drain the
water in the cooling tower.
Use an anti-freeze. (For using an anti freeze, change the DIP switch
on main PCB in outside unit.)
Refer to the additive amount about freezing temperature as in the
table given below.
Anti freeze type
Minimum temperature for anti freezing (°C)
0 -5 -10 -15 -20 -25
Ethylene glycol (%) 0 12 20 30 - -
Propylene glycol (%) 0 17 25 33 - -
Methanol (%) 0 6 12 16 24 30
- In addition to anti freeze, it may cause the change of the pressure in
the water system and the low performance of the product.
- Make sure to use the closed cooling type tower.
When applying the open type cooling tower, use a 2nd heat exchanger to make the water supply system a closed type system.
Standard table for water purity control
The water may contain many foreign substances and hence may influence the performance and lifetime of the product due to the corrosion
of the condenser and water pipe. (Use water source that complies
with the below standard table for water purity control.)
If you use water supply other than the tap water to supply the water
for the cooling tower, you must do a water quality inspection.
- If you use the closed cooling tower, the water quality must be controlled in accordance with the following standard table.
If you do not control the water quality in accordance with the following standard water quality table, it can cause performance deterioration to the air conditioner and severe problem to the product

• The "O" mark for corrosion and scale means that there is possibility of occurrence.
• When the water temperature is 40°C or above or when uncoated iron is exposed to the water, it can result in corrosion.
Therefore adding anti-corrosion agent or removing the air can be
very effective.
• In case of using the closed type cooling tower, the cooling water
and supplementing water must satisfy the water quality criteria
of closed type system in the table.
• Supplementing water and supplied water must be supplied with
tap water, industrial water and underground water excluding filtered water, neutral water, soft water etc.
• 15 items in the table are general causes of corrosion and scale.

REFRIGERANT PIPING INSTALLATION
WARNING
!
Always use extreme care to prevent the refrigerant gas (R410A)
from leakage while using fire or flame. If the refrigerant gas
comes in contact with the flame from any source, such as a gas
stove, it breaks down and generates a poisonous gas which can
cause gas poisoning. Never perform brazing in an unventilated
room. Always conduct an inspection for gas leakage after installation of the refrigerant piping has been completed.

Nitrogen substitution method
Welding, as when heating without nitrogen substitution a large
amount of the oxide film is formed on the internal piping.
The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of oil pump in compressor.
It prevents normal operation of the compressor.
In order to avoid this problem, Welding should be done after replacing
air by nitrogen gas.
When welding plumbing pipe, the work is required.
WARNING
!
After completing work, securely tighten both service ports and
caps so that gas does not leak.

I
Refrigerant Pipe
3 pipes are connected to the HR unit from the outside unit, classified
into liquid pipe, low pressure gas pipe and high pressure gas pipe depending on status of refrigerant passing through the pipe.
You must connect 3 pipes from outside unit to HR unit.
For connection between indoor unit and HR unit, you must connect
both liquid pipe and gas pipe from the HR unit to the indoor unit. In this
case, connect them to the indoor unit starting from No.1 connection
port of the HR unit (the port number is displayed on ports of the HR
unit). Use auxiliary flare as annexed parts in connection to the indoor
unit.
CAUTION
!
Whenever connecting the indoor units with the HR unit, install the indoor units in numerical order from No.1.
Ex) In case of installing 3 indoor units : No. 1, 2, 3 (O), No. 1, 2, 4 (X),
No.1, 3, 4 (X), No.2, 3, 4 (X).
ENGLISH
CAUTION
!
When installing the branch pipe vertically between the outside
units, the refrigerant can be uneven between the outside units,
leading to compressor burn and reduced capacity.
Installation procedure for HR unit
1 Using an insert-hole-in- anchor, hang the hanging bolt.
2 Install a hexagon nut and a flat washer (locally-procured)to the hang-
ing bolt as shown in the figure in the bottom, and fit the main unit
to hang on the hanger metal.
3 After checking with a level that the unit is level, tighten the hexagon
nut.
* The tilt of the unit should be within ±5° in front/back and left/right.
4 This unit should be installed suspended from ceiling and side A
should always be
facing up.
5 Insulate not used pipes completely as shown in the figure.
Type of HR Unit
Select an HR unit according to the number of the indoor units to be installed. HR units are classified into 3 types by the number of connectable indoor units.
Ex) Installation of 6 indoor units
Consists of HR unit for 4 branches and HR unit for 2 branches.
Joint Method of HR Unit (Big Duct : ARNU76GB8-,
ARNU96GB8-)
Joint Method is required when B5/B8 chassis is installed. In Joint
Method, two neighboring outlets of one HR unit are linked by Y branch
pipe and connected to one indoor unit.
