6.3 Trial run
6.3.1 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.
6.3.2 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.
6.3.3 After the unit is shut down, it should be put into operation 10
min 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 9.1.
CAUTION
7. USE
●
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.
