1.Any 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.


2.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.


3. When not operating (and with mains power supply turned off) check the equipment to see whether it’s over heating, check the stability and corrosion of all the wire plugs.


4. Replace the heating elements:
Switch off the steam generator (at mains) and remove the element access cover when the generator has completely cooled 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 in the electrical wires making sure the heating elements are properly connected before re-fitting the element access cover.


5. Replace the main board:
Switch off the steam generator (at mains) and remove the U shape 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 new main board carefully.


6. Replace the sub-board:
Switch off the steam generator (at mains) and remove the U shape cover when the generator has completely cooled down. Unplug all the wires on the sub-board. Label all the wires on the relay and remove the sub-board. Install the new sub-board carefully.


7. Replace the solenoid valve, drain valve and Auto drain motor (drain pump):
Switch off the steam generator (at the mains) and disconnect from the power and water supply. Remove the water inlet, steam outlet and draining pipelines after the generator has completely cooled down. Then 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 install the new replacing valve carefully.


8. Replace the water level sensor:
Switch off the steam generator (at the mains) and remove the small cover on the casing when the generator has completely cooled down. Special care should be taken to the wires 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 wire must be re-connected ensuring correct connections. (Refer to figure 9-12)


CUT OFF THE POWER SUPPLY BEFORE ANY MAINTENANCE.

TEST THE EQUIPMENT AFTER MAINTENANCE.
