LO-1600W Water Chiller Operation Manual
1) Ensure good contacts on the AC power pug: L, N, and G
2) Stable AC voltage is necessary. +/-5%
3) Stable AC frequency (Hz) is required. No square wave or modified sinusoid wave accepted
4) Do not operate without water or the water pump will suffer damage.
5) Remove any obstacle that is blocking the intake or the outlet from the fan
6) Air filter need to be cleaned periodically.
7) Change water every 2 weeks. Distilled water is highly recommended.
8) Operate the unit by trained and skill personnel only.
Introduction
The LO-1600W is an industrial grade water chiller with a high efficiency compressor running on R410A
environmental friendly Freon. The chiller is controlled by the sophisticated microcontroller with a large easy LCD
readout. Two control modes Intelligence or Constant provides an accurate and fast control to the change of
temperature.
Control modes
Intelligence – The target temperature changed accordingly upon the change from the ambient temperature. The
amount of temperature change (drop) is controlled the 'deviation' value.
Constant – The target temperature is fixed at set by the "SV" parameter. Regardless of how an ambient
temperature changes, the chiller will always reach the target temperature with a plus or minus variation of the
'Feedback' value
