8 COOLZY-PRO Model PC9RL User Guide EN2022 Rev1.1
Snowflake (blue light)
The cooler temperature so low that there is a risk that ice may form, damaging the
tubes in Coolzy. Some combinaons of low temperature, humidity and atmospheric
pressure can lead to frosng. Allow the fan to operate for a few minutes to warm up
Coolzy.
Also, check the air inlet lters for excessive dust build-up. Ensure that there is nothing
blocking the either of the air inlets such as a curtain, cushion or bedding.
Thermometer (red light)
The compressor has overheated. Coolzy can be used in ambient temperatures up to
40 °C. Above that temperature, the compressor may overheat. Wait for 10 – 20 min-
utes and try again. Avoid using Coolzy in direct sunlight.

TROUBLESHOOTING
Symptom 1 – Green light is not on when trying to turn on
Coolzy
Make sure the warm air deector is fully open. Check to see if the power supply is
properly connected and on. If the power cord seems properly connected, try a dier-
ent power supply. Make sure you push the cable drawer fully back in so it aligns with
the back panel.
Symptom 2 – Green light is on with no cooling
The green light ashes, the fan runs and the compressor waits to start cooling for
about 90 seconds. This delay protects the compressor from damage.
If the green light is on and the fan is running, and there is no apparent cooling aer 2
minutes, check that Coolzy is in cooling mode. Press the ‘FUNC’ buon on the remote
unl the snowake icon appears to acvate cooling mode. Reduce the temperature
seng because the thermostat may be prevenng the compressor from starng.
Symptom 3 – Water sloshing noise
In extremely high humidity, the producon of condensed water may exceed the ca-
pacity to evaporate water at the condenser heat exchanger. As more water accumu-
lates than in normal condions, there may be a percepble sound of water cascading
o the condenser at the back of the machine. This is normal behaviour. If the sound
is annoying, consider removing the rubber bung temporarily. The water will drain into
the cable drawer. However the machine will stop cooling when the cable drawer is
full of water.
Symptom 4 – Room seems to warm up
As you become accustomed to the cool microclimate that Coolzy provides for you,
the other parts of the room may seem to be warmer. There may be a slight increase
in air temperature in the space above the warm air deector, but this is normally not
enough to heat up the lower part of the room.
Keep a door or window open. This is a healthy opon. Posion Coolzy’s warm air
outlet to face the open window or door so warm air can ow out more easily. Unlike
normal room air condioners, Coolzy works just best with open doors or windows
