Coolzy.
Also, check the air inlet filters 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
104 °F (40 °C). Above that temperature, the compressor may overheat. Wait for 10 –
20 minutes 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 deflector is fully open. Check to see if the power supply is
properly connected and on. If the power cord seems properly connected, try a dif-
ferent power supply. Check that the cable drawer is fully inserted and flush with the
back of Coolzy.
Symptom 2 – Green light is on with no cooling
The green light flashes, 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 after
2 minutes, check the room air temperature. The compressor will only run at an air
temperature greater than 63 °F (17 °C).
Symptom 3 – Water sloshing noise
In extremely high humidity, the production of condensed water may exceed the ca-
pacity to evaporate water at the condenser heat exchanger. As more water accumu-
lates than in normal conditions, there may be a perceptible sound of water cascading
off the condenser at the back of the machine. This is normal behaviour. If the sound
is annoying, consider removing the stopper 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 deflector, 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 option. Position Coolzy's warm air
outlet to face the open window or door so warm air can flow out more easily. Unlike
normal room air conditioners, Coolzy works just best with open doors or windows
and fresh air circulating.
A slight temperature increase can occur in a small room, especially if the windows are
closed. The setup instructions show how to minimize this effect. Visit www.coolzy.
