10 TEST RUN AND FINAL CHECK
10.1 Check item table after installation
Table 10-1
Checking item
Whether installing site is meet for
requirements
Whether water system is meeting for
requirements
Whether electric wiring system is
meeting for requirements
10.2 Trial run
1) Start up the controller and check whether the unit displays a fault code. If a fault occurs, remove the fault first, and start the
unit according to the operating method in the "unit control instruction", after determining that there is no fault existing in the unit.
2) Conduct trial run for 30 min. When the influent and effluent temperature becomes stabilized, adjust the water flow to nominal
value, to ensure normal operation of the unit.
3) After the unit is shut down, it should be put into operation 10 minutes later, to avoid frequent start-up of the unit. In the end,
check whether the unit meets the requirements according to the contents in Table 11-1.
The unit can control start-up and shut-down of the unit, so when the water system is flushed, the operation of the
pump should not be controlled by the unit.
Do not start up the unit before draining the water system completely.
The target flow controller must be installed correctly. The wires of the target flow controller must be connected
according to electric control schematic diagram, or the faults caused by water breaking while the unit is in operation
should be the user's responsibility.
Do not re-start the unit within 10 min after the unit is shut down during trial run.
When the unit is used frequently, do not cut off the power supply after the unit is shut down; otherwise the
compressor cannot be heated, thus leading to its damages.
If the unit is not in service for a long time, and the power supply needs to be cut off, the unit should be connected to
the power supply 12 hours prior to re-starting of the unit, to pre-heat the compressor,the pump,the plate heat
exchanger and the differential pressure value.
