Using the Steamer (Auto Refill)
1.5.1. Function of the steamer
The Combi Heater includes a Steamer with a capacity of 5 liter of water. An automatic refilling system
makes it possible to produce steam without interruptions. The tank will automatically be refilled
when the water level reach the low water detection. As a security feature, if there is no refill of an
empty tank, the low water detection system will automatically turn off the steamer heater. A FILL
message is displayed together with a buzzer tone on the external unit. If there is a valve on the water
supply make sure it is turned on position before turning steamer on. After refilling water, the steam
generator heater turns on again after a short while. The buzzer will stop alarming when water is filled,
or when the heating element is not hot anymore. The water level in the tank can easily be monitored
through the water level indicator.
Caution: Streamer cover and scent basins are very hot if the heater is in use. Do not touch them by
bare hand.
1.5.2. Operation
All operations are handled through the external control unit. Choose either a normal bath or a steam
sauna bath. For normal sauna baths switch OFF the steamer.
For steam sauna baths switch ON the steamer. The steamer system will automatically start to produce
steam. To ensure ideal humidity, the sauna temperature should be 40 - 50°C. Before a bath the
steamer should be left on for about 30 minutes to pre-heat the sauna and produce sufficient amount
of steam. When FILL appears on the external control unit’s display, water is automatically filled into
the water tank. After every sauna bath the water tank must be drained (section 1.6).
Common for Manual and Auto Refill Steamers
1.6.1. Draining and cleaning the water tank
In order to ensure best water quality the water tank must always be emptied after use. This
procedure removes impurities condensed in the tank as result of evaporation. The water should be
drained only after cooling down since it is very hot immediately after using the steamer. To drain the
tank turn the ball valve handle at the bottom of the steam generator tank counterclockwise until
water flows. Provide a container (i.e. a bowl) to collect the water. Before cleaning the inside of the
water tank remove its cover first (section 1.1.3). Do not attempt to clean the inside of the tank by
hand and a cloth to avoid injuries caused by the tank’s edges. To clean the tank separation plate, lift it
up and clean it with water and a household brush (Fig. 5). Finally flush the tank with water and close
the ball valve by turning its handle clockwise. Do not use a steel brush as it might damage the tank
wall or bottom heating plate. Do not forget to refill water before turning the steamer on again. Do
not let the steamer water tank run dry as an alternative method of draining the water. The lifespan of
your Combi Heater will be shortened. Impurities from water, e.g. lime, will accumulate on the walls of
the steamer's water tank. For decalcification SAWO recommends decalcifying agents intended for
household appliances, e.g. coffeemakers and water kettles. These agents are to be applied as
instructed by the manufacturer. The outside of the steamer tank should be cleaned with a damp
cloth. When cleaning the outside, ensure that the Combi Heater’s power switch is in off position.

1.6.2. Using scents
Liquid scents can be used with the Combi Heater to make your sauna bath more enjoyable.
Scents can be poured in the provided scent basins inserted in the water tank cover’s openings
(section 1.1.2). Avoid pouring scents while the steam generator is on.
The hot steam might cause burns. The scent basins shall be brushed and rinsed with water
after using them with scents.
