Critical Parameter

3. Critical Parameter

4. Unpack

Before unpacking, check the anti-tilt sign is in good

condition, the outer packing of the machine is in

good condition, and the machine model is

consistent with what you have purchased.

Take out accessories and documents, check for its

consistency with packing list.

If there is any discrepancy or damage, please

contact our company/distributor directly

5. Installation Location

The ice maker is not suitable for outdoor usage,

the installation location should not be closed to

heat source or be exposed under direct sunlight.

The normal working ambient temperature should

be ranged between 10°C～38°C, the water

temperature should be between 5°C～32°C. If the

ice-making machine operates beyond the above

normal temperature range for a long time, its

ice-making capacity may be affected.

Ice makers should be installed on solid, flat

ground.

Ice makers should be placed near drinkable water

supply. It is recommended that distance between

ice makers be less than one meter.

Do not block the ventilation window of the ice

maker. There should be enough air convection

space around the ice maker.

The ice maker can not work at sub-zero

emperatures, to prevent supply line failures, empty

the ice maker when the temperature is below

zero(see“Ice machine stop / winter”)
