Thank you for purchasing Stepless Electrical Co., Ltd., Dongguan City,
the product, please read the installation instructions carefully before use and
safekeeping.
The installation instructions are not using quality assurance, to correct
typographical errors in the information the fallacy of errata, and improved
products, by the Electrical and Mechanical Services Ltd. of Dongguan City,
stepless explanation at any time, without prior notice, amendments will be
incorporated Republication using the installation instructions.
01
Please ensure that the power supply and electrical outlet are in good contactand the earth wire
must be firmly grounded!
Although the average operating current of the chiller is small, but theinstantaneous operating current could be up to 6~10amps
sometimes (Theinstantaneous operating current of models of AC110V power supply arepossible to be up to 10~15amps).
02
Please make sure there is stable and normal voltage for the working chiller!
As the refrigeration compressor is more sensitive to the power supply and voltage, so the operating voltage of our standard
product is of 200~250V (110V model is of 100~130V). If you do need a wider operating voltage range,customization is
available for us.
03
Unmatched power frequency can cause the chiller damage!
Please choose model of 50Hz or 60Hz according to actual circumstance.
04
To protect the pump, it’s strictly forbidden to run the chiller without water in the storage water tank!
The new machine is packed after draining whole water in the tank, so please make sure the tank has water inside before machine
starting, otherwise it’s easily to have the pump damaged. When the water level is below the green(NORMAL) range of the water level
gauge, the cooling capacity of our chiller will go down slightly. Hence please ensure the water level is within the green (NORMAL)
range. To drain through circulating pump is strictly prohibited!
05
Please be sure that the air inlet and air outlet are in good ventilation!
There must be at least 30cm from obstructions to the air outlet which is in the back of the cooler, and should leave at least 8cm
between obstructions and the side air inlet.
06
The filter screen must be regularly cleaned!
It’s essential to unpick and wash the dust gauze, or the serious blockage will cause breakdown to the chiller.
07
Please pay attention to the effect of the condensate water!
With greater ambient humidity, when the water temperature is lower than the ambient temperature, the condensate water will
generate on the surface of water circular pipes and the cooled components. If above circumstance appears, it is recommended to set
a higher water temperature or keep pipes and cooled parts warm.
Professional use only!
The appliance is not to be used by children or persons with reduced physical,sensory or mental capabilities, or lack
of experience and knowledge, unless they have been given supervision or instruction, children being supervised not
