Maintenance
As leakage of the steam will damage the equipment. To prevent any hazard, steam generators,
steam head, parts and pipe line connections should be checked regularly.
Clean the solenoid valve, magnetizer and all the other sets in the pipe line regularly according to
the local water quality and usage of the steam generator.
When operate, check the equipment to see whether it’s over heated, check the stability and
corrosion of all the wire plugs.
i. Replace the heating elements:
Switch off the steam generator and remove the element access cover when the generator
completely cools down. Label the wires connect to the heating elements which need to be
replaced and plug out the wires. Screw the heating elements out. Clear the scale in the
water tank and screw in the heating elements after putting the rubber rings on them
(airproof gasket should be pressed firmly without reversion). Plug on the wires, make sure
the heating elements are properly connected before put on the element access cover.
ii. Replace the main board:
Switch off the steam generator and remove back cover when the generator completely cools
down. Label the three wires which connect the upper part of the main board to the water
level sensor and the source, drain valve and water inlet solenoid valve in the bottom part of
the main board. Unplug these wires and remove the main board (be careful with
yellow-green ground wire under the screws of the circuit board). Install the main board back
carefully.
iii. Replace the sub-board:
Switch off the steam generator and remove the back cover when the generator completely
cools down. Unplug all the wires on the sub-board. Label all the wires on the relay and
remove the sub-board. Install the sub-board back carefully.
iv. Replace the solenoid valve, drain valve:
Switch off the steam generator and disconnect from the power and water supply. Remove
the water inlet, steam outlet and draining pipelines after the generator completely cools
down. Then please lean the steam generator to remove the base panel. After that, please
take off the soft pipes, wires and screws so that the faulty valve could be removed. Finally
please install the replacing valve carefully.
Cut off the power supply before any maintenance.
Test the equipment after maintenance.
