The Combi Heater is equipped with an automatic water refilling system that makes it possible to
produce the steam without refilling water manually.
The Steamer Tank will automatically be refilled with water upon turning ON the control unit
and will be refilled with water automatically once the water level is already near the low-water
detection mark.
As a security feature, if the Water Tank is not refilled automatically for any possible reason, the Low
Water Detection System will automatically turn off the Steamer. And the word “FILL” will be
displayed on the external Control Unit and a warning sound (buzzer-like) will be emitted. (Refer to
Part5 Troubleshooting)
3.5. Using the Steamer with Built-in Automatic Refill System
NOTE:
Make sure that there is enough supply of water and the water supply pressure must be in the
range of 1 to 2 bar to have a smooth automatic refill system function and check the water
connection that it is properly connected to the water inlet of the steamer before turning ON the
steamer ( Refer to Figure 1 ).
The Water Tank should be emptied and cleaned after every use to ensure that always fresh and
clean steam is produced.
Wait for the unit to cool down before draining the water.
To drain the water, turn the Ball Valve handle at the bottom of the Steamer Tank counterclockwise
until water flows out of the tank. Provide a container to collect the water.
For the Super Nimbus Combi, both tanks shall be drained.
Every 500 hours of use or 6 months whichever comes first, disconnect the connection hose of the
two tanks and rinse with water to remove particles inside the hose that will cause water clog up.
Do not forget to connect back the hose of the two tanks after cleaning. See Figure 9.
Once the tank is completely drained, remove the Steamer Cover and clean the tank inside with a
household brush to remove impurities that have accumulated in the tank, and then rinse with
water.
Do not use a steel brush as it might damage the tank wall or the bottom heating plate.
Do not clean the water tank inside with a cloth to avoid hand injuries that may be caused by the
tank’s edges.
To clean the tank’s separation plate, lift it up and clean it with water and a household brush. See
Figure 10. •

3.6. Draining and Cleaning the Water Tank
Finally, flush the tank with water and close the Ball Valve by turning its handle clockwise.
Before using the Steamer again, do not forget to refill the Water Tank (not applicable for Built-in
Automatic Refill System).
Do not let the Water Tank run dry as an alternative method of draining the water, this will shorten
the life span of the Steamer hot plate.
It will not be helped that impurities from the water (e.g. lime) will accumulate on the walls of the
Water Tank. To decalcify, SAWO recommends decalcifying agents intended for kitchenwares such
as for coffeemakers and water kettles. These agents should be applied as instructed by their
manufacturer.
Clean the outside of the Water Tank with a damp cloth. While doing this, make sure that the
Combi Heater is turned off.
