IMPORTANT
●
Never operate the product when the pump is dry. Always fill the water tank and check the
water level before operating. Failure to add water and running the product dry can result in
pump breakdown.

．
Frequently turning on and off the product can damage it. After stopping the product, wait at least 3
minutes before starting again. Starting the product within 3 minutes after stopping will cause built-in
safety functions to activate and can cause damage to the compressor.
5
．
Confirm there is no dirt on the water piping and foot valve.
6
．
Always keep the water clean, inspect the water circuits monthly, and replace the water when
necessary.
(See "Water circuit inspection" on page 25 for details.)

CAUTION
●
Always cut off the main power before starting maintenance, cleaning, or inspection. Leaving
the power supply connected while work is in progress may result in electric shock.
8. Ambient temperature must be maintained in the range of 5
℃
to 40
℃
. Operating this cooler below
5
℃
can result in failure of the condenser. On the other hand, operating the cooler at a temperature
higher than 40
℃
can degrade heat dissipation from the condenser, thereby activating the safety
device and stopping the cooler operation. When ambient temperature is anticipated to reach 40
℃
or
above, install a duct to conduct outside air to the suction port on the cabinet or prepare an exhaust
port to discharge hot air. In this case, you are advised to contact your dealer or a specialized
provider before installing such arrangement.
9. If the cooler is shut down by tripping of a safety device, please contact your dealer.
