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 consid-
ered 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.
These days the developed countries have approved it as the environ-
ment-friendly refrigerant and encouraged to use it widely to prevent
environment pollution.

! 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, stagna-
tion, and leak of combustible gas is expected.
• Avoid unit installation in a place where acidic solution and spray (sul-
fur) 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 condi-
tions.
• 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.)
CAUTION
!
• Do not install Multi V water outside. Always install indoor like
machine room.
• Inverter product may generate electric noise. Keep the body
from computer, stereo etc. at enough distance. Specially leave
space from indoor remote controller to shoes electric devices at
the above 3m in weak electric wave area. Insert the power
cable and other wire into separate conduit.
