Maintenance:
Any leakage of the steam will damage the equipment. To prevent any hazard, steam generators, steam head, parts and pipeline connections should be
checked regularly. Clean the solenoid valve, water treatment cartridge and all the other sets in the pipeline regularly according to the local water
quality and usage of the steam generator.
Periodically, check the equipment visually to see whether it's over heated, check the stability and corrosion of all the wire plugs.
Replace the heating elements:
Switch off the steam generator at the mains/isolation switch and remove the element access cover when the generator completely cools down. Label
the wires which connect to the heating elements which need to be replaced and unplug the wires. Unscrew the heating elements from the housing.
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 replacing the element access cover.
Replace the sub-board:
Switch off the steam generator and remove the U shape 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.
Replace the solenoid water inlet valve:
Switch off the steam generator at the mains/isolation switch and disconnect the water supply. Remove the water inlet, steam outlet and draining
pipelines after the generator completely cools down. Then lean the steam generator over to remove the base panel. After that, remove the soft pipes,
wires and screws so that the faulty valve could be removed. Reverse this process to install the replacing valve.
Replace the water level sensor:
Switch off the steam generator at the mains/isolation switch and remove the small cover on the equipment when the generator cools down. Special
care should be taken with the plugs of the water level sensor corresponding to the blue wire, the red wire, and the white wire respectively. Take off all
the wires, screw out the water level sensor, and screw in the new water level sensor until the bottom of the plastic nut reaches the same height as the
old one. Finally reconnect the wires (all wires must be plugged back into the right place).
Always cut off the mains power supply before any maintenance. Test the equipment after maintenance.
