too low (in heating mode)
or too high (in cooling
mode).
2.1 The room was probably
very hot when you
started the system.
3.1 In heating or cooling

parts may expand or
shrink due to a sudden

this event, a clicking
sound may occur.

OPERATION TIPS
The following events may occur during normal operation:
Compressor protection
•
The compressor cannot restart for 3 minutes after it stops.
The supply air drops below a pre-determined set point; this prevents
the indoor coil from freezing.
A white mist may generate due to a large temperature difference
between air inlet and air outlet on COOL mode in an indoor
environment that has a high relative humidity.
You may hear a low hissing sound when the compressor is running or
has just stopped running.
This sound is the sound of the refrigerant flowing 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.
This is a normal condition when the air conditioner has not been used for a
long time or during first use of the Unit.
This is caused by the Indoor unit giving off smells permeated from building
material, from furniture, smoke (for example if someone is cooking food), or
from the duct work.
When indoor air temperature reaches the setting on the Spectrolink wall
control, the compressor will stop operating and after approximately 60
seconds the indoor fan will stop blowing air. When the room temperature rises
back to the set point, the indoor fan and the compressor will start again.
1. Protection of the air conditioner.
2. A white mist coming out from the Indoor unit.
3. Low noise of the air conditioner.
4. Dust is blown out from the Indoor unit.
5. A peculiar smell comes out from the Indoor unit.
6. FAN operation during COOL mode.
