Ensure the flow rate is in the range. Low flow rate will reduce performance of the unit due to scale formation,
triggering anti-freeze sensor, and/or refrigerant leakages which caused by corrosion. While flow rate that is too
high will cause erosion corrosion.
■
■
An insulated water tank with a proper volume is recommended to be installed. If the capacity is too small,
the unit might frequently restart, which causes wear and tear on the compressor.
.
■
An expansion tank is recommended to be install at the return of the chilled water system. Water inside the
chilled water system will experience volume changes due to temperature changes.
■
An auto relief valve must be installed at the highest point in the water system. A suitable water discharge valve
must be installed at the lowest point in the water system.
■
The water pipes must be insulated to avoid heat loss and condensate water.
■
Please follow the "Illustration for water system installation" and drawings from the certified personnel while
installing the water system.
Install the strainer on the inlet pipe and rinse the filter screen after commissioning.
■
■
Before supplying water, make sure that no sand, rubble, rust, soldering residue or other impurities exist in the pipe.
As these things might damage the heat exchanger.
While rinsing the water system, please bypass the unit and the terminal heat exchanger using by-pass valves.
