6. TRIAL RUN

6.1 Points for attention prior to trial run
6.1.1 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.
6.1.2 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.
6.1.3 Setting of 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.
6.1.4 Carefully adjust the target flow controller 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 in Table
