CARE AND MAINTENANCE
Operating Conditions
The temperature ranges compatible with the
unit are as follows:
MODE INDOORS OUTDOORS
REFRIGERATION 21~32°C 21~46°C
DEHUMIDIFICATION 17~32°C 12~46°C
• When the unit is operating below or above
these conditions for an extended period of
time, the diagnostics system will detect a
malfunction and the unit will not function
properly.
• If the unit is operating under abnormal
conditions for an extended period of time,
or under extreme humidity, condensation
may be formed inside the unit.
Minimum Operating Time
• In normal operations, there is a minimum
of 3 minutes between each shutdown and
startup of the compressor.
Operation in the event of power outages
• When an electrical power outage occurs
and the unit is in operation, the operating
conditions are saved and restored
automatically when the electricity returns.
• The programming of the TIMER will be
lost.
• On leaving your house during a power
outage, disconnect the indoor unit to
prevent it from switching itself on
automatically when the power returns.
Prevention of freezing in the indoor unit
• When the unit is operating in conditions of
low ambient temperature, ice may appear
on the coil of the indoor unit. When the
temperature of the indoor coil is below
zero degrees Celsius, the electronic
control will cause the compressor to
disconnect to protect the freezing unit.
Normal operation
Some of these events may occur during
normal operation:
• A “warbling” sound during operation or
when the unit stops – This is the sound of
the refrigerant gas flowing through the
unit.
• Bad odors coming from the unit – Smoke
or cosmetic odors which have
accumulated while the room air was
circulating through the unit.
• The green light on the indoor unit flashes
and there is no ventilation.
- Indicates a malfunction of the unit, and
the compressor will stop operating.
• A loud noise can sometimes be heard
while the unit is operating or when the unit
is switched on - this is the sound of the
plastic expanding due to rapid changes in
temperature.
