5.1 Points for attention prior to trial run

After the water system pipeline is flushed several times, please make sure that the purity of water meets the
requirements; the system is re-filled with water and drained, and the pump is started up, then make sure that
water flow and the pressure at the outlet meet the requirements.
The unit is connected to the main power 12 hours before being started up, to supply power to the heating belt
and pre-heat the compressor. Inadequate pre-heating may cause damages to the compressor.
Set up the wired controller. See details of the manual concerning setting contents of the controller, including
such basic settings as refrigerating and heating mode, manual adjustment and automatic adjustment mode
and pump mode. Under normal circumstances, the parameters are set around standard operating conditions
for trial run, and extreme working conditions should be prevented as much as possible.
Carefully adjust the water flow switch on the water system or the inlet stop valve of the unit, to make the water
flow of the system be 90% of the water flow specified as below Table.
