12 ALTERNATIVE REFRIGERANT R410A
ENGLISH
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.
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.

Seasonal wind and cautions in winter
• Sufficient measures are required in a snow area or severe cold area in winter so that product
can be operated well.
• Get ready for seasonal wind or snow in winter even in other areas.
• Install a suction and discharge duct not to let in snow or rain.
• Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes
on the air suction hole, the system may malfunction. If it is installed at snowy area, attach the
hood to the system.
• Install the outdoor unit at the higher installation console by 50cm than the average snowfall
(annual average snowfall) if it is installed at the area with much snowfall.
• Where snow accumulated on the upper part of the Outdoor Unit by more than 10cm, always
remove snow for operation.
- The height of H frame must be more than 2 times the snowfall and its width shall not
exceed the width of the product. (If width of the frame is wider than that of the product,
snow may accumulate)
- Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal
wind.
