5.9Trial Operation
Check the piping system. Check whether the expansion water tank is filled with sufficient
water and whether the water supply for supplement is normal. Check whether the entire
piping system is full of water and whether the air is completely exhausted. Check
whether all valves in the system are opened. Check whether the pipelines are well
insulated.
Check the power distribution system. Check whether all power supplies have normal
voltage. Check whether screws of each power distribution part are locked, and whether
the power is distributed to the circuit according to the distribution wiring diagram. Check
whether the ground line is well connected.
Check the water chilling unit. Check whether all fastening screws and screws on the
mechanical parts of the unit are firm. Check whether there is any fault indication on the
operation lights on the outdoor control main board. Connect the pressure gauge to the
fluoridated inlet to detect the system pressure during operation.
