Operating Conditions; Features; Auto-Restart; A White Mist Coming Out From The Indoor Unit - Garrison 3554190 Owner's Manual

NOTE: For multi-split-type air conditioners, one outdoor unit can match di erent types of indoor
units. Therefore, all the pictures in this manual are for explanation only. Your air conditioner may
be slightly di erent. The actual shape shall prevail.
The following pages introduce several kinds of indoor units matching with the outdoor units.

Features

Protection of the air conditioner
Compressor protection
• The compressor can't restart for 3 minutes
after it stops.
Anti-cold air (Cooling and heating models
only)
• The unit is designed not to blow cold air on
HEAT mode, when the indoor heat exchanger
is in one of the following three situations and
the set temperature has not been reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
• The indoor or outdoor fan stops running when
defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models only)
• Frost may be generated on the outdoor unit
during heat cycle when outdoor temperature is
low and humidity is high, resulting in lower
heating e ciency of the air conditioner.
• During this condition, air conditioner will stop
heating operation and start defrosting
automatically.
• The time to defrost may vary between 4 to 10
minutes according to the outdoor temperature
and the amount of frost buildup on the
outdoor unit.
Auto-Restart (some models)
In case of power failure, the system will
immediately stop. When power returns, the
Operation light on the indoor unit will flash. To
restart the unit, press the ON/OFF button on the

A white mist coming out from the indoor unit

• A white mist may generate due to a large
temperature di erence between air inlet and
air outlet on COOL mode in an indoor
environment that has a high relative humidity.
• A white mist may generate due to moisture
generated from defrosting process when the
air conditioner restarts in HEAT mode
after defrosting.
Low noise of the air conditioner
• You may hear a low hissing sound when the
compressor is running or has just stopped
running. This sound is the refrigerant
owing or coming to a stop.
• You can also hear a low "squeak" sound when
the compressor is running or has just stopped
running. This is caused by heat expansion and
cold contraction of the plastic parts in the unit
when the temperature is changing.
• A noise may be heard due to louver restoring
to its original position when power is rst
turned on.
Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner
has not been used for a long time or during rst
use of the unit.
A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving o smells
permeated from building materials, furniture,
or smoke.
