Insufficient insulation can cause condensation, which can lead to moisture damage on
the ceiling, floor, furniture and any other valuables.
• When perform the air conditioner operation (cooling or drying operation) in
which ventilator is installed in the room. In this case, using the air conditioner
in parallel with the ventilator, there is the possibility that drain water may
backflow in accordance with the room lapse into the negative pressure status.
Therefore, set up the opening port such as incorporate the air into the room that
may appropriate to ventilation (For example; Open the door a little). In addition,
just as above, so set up the opening port if the room lapse into negative
pressure status due to register of the wind for the high rise apartment etc.
• Be sure to perform air tightness test by pressurizing with nitrogen gas after
completed refrigerant piping work.
If the density of refrigerant exceeds the limit in the event of refrigerant leakage in the
small room, lack of oxygen can occur, which can cause serious accidents.
