Before the test run

CAUTION
Turn on the unit at least 12 hours before the test run.
Keep the unit turned on throughout the season. If the unit is
turned off in the middle of a season, it may result in malfunc-
tions.
To avoid the risk of electric shock or malfunction of the
unit, do not operate switches with wet hands.
Do not touch the refrigerant pipes with bare hands dur-
ing and immediately after operation.
During or immediately after operation, certain parts of the
unit such as pipes and compressor may be either very cold
or hot, depending on the state of the refrigerant in the unit
at the time. To reduce the risk of frost bites and burns, do
not touch these parts with bare hands.
Do not operate the unit without panels and safety
guards.
Rotating, high-temperature, or high-voltage parts on the unit
pose a risk of burns and/or electric shock.
HWE1410A
Do not turn off the power immediately after stopping
the operation.
Keep the unit on for at least five minutes before turning off
the power to prevent water leakage or malfunction.
Do not operate the unit without the air filter.
Dust particles may build up in the system and cause mal-
functions.
Use circulation and makeup water that meet the water-
quality standards.
Degradation of water quality can result in water leakage.
In areas where temperature drops to freezing during
the periods of non-use, blow the water out of the pipes
or fill the pipes with anti-freeze solution.
Not doing so may cause the water to freeze, resulting in
burst pipes and damage to the unit or the furnishings.
