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.
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 outdoor unit, which will meet the following
conditions:
• No direct thermal radiation from other heat sources
• No possibility of annoying neighbors by noise from unit
• No exposition to strong wind
• With strength which bears weight of unit
• Note that drain flows out of unit when heating
• With space for air passage and service work shown next
• Because of the possibility of fire, do not install unit to the space
where generation, inflow, stagnation, and leakage of combustible
gas is expected.
• Avoid unit installation in a place where acidic solution and spray (sul-
fur) are often used.
• Do not use unit under any special environment where oil, steam and
sulfuric gas exist.
• It is recommended to fence round the outdoor unit in order to pre-
vent any person or animal from accessing the outdoor unit.
• If installation site is area of heavy snowfall, then the following direc-
tions should be observed.
- Make the foundation as high as possible.
- Fit a snow protection hood.
• Select installation location considering following conditions to avoid
bad condition when additionally performing defrost operation.
- Install the outdoor unit at a place well ventilated and having a lot of
sunshine in case of installing the product at a place With a high hu-
midity in winter (near beach, coast, lake, etc.)
(Ex : Rooftop where there is always sunshine.)
