Operate the product in an ambient temperature of 5
℃〜
40
℃
.
Operating at temperatures below 5
℃
will damage the compressor.
Also, operating at above 40
℃
will result in a drop in heat transfer of
the condenser, and may cause built-in safety devices to activate,
and stopping of product operation.
If the ambient temperature will exceed 40
℃
, either draw cool
outside air into the product by installing ducting on the air intake on the
cabinet, or duct heated ventilation air from the product to the outside.
If such measures are to be taken, ensure that such construction
does not result in a drop in fan air flow.

If ducting is to be installed, consult with qualified installation engineer.
IMPORTANT
● If ducting is to be installed, be sure to construct it such that there is no narrowing along the
way. Failure to do so can result in built-in safety devices activating, which can cause product
operation to stop.
