Steam Generator

The combi heater includes a steam generator to produce steam inside the sauna room. The steam
generator has a 5 litres tank which produces steam for about 1hour 30 minutes (with 5 litres of water)
with setting MAX on the external control unit .

To ensure ideal humidity, the sauna temperature should be between 40 and 50ºC (140 and 122ºF),
and the steam generator should be left on for about 30 minutes to pre-heat the sauna and produce
sufficient amount of steam.

Draining the water reservoir

In order to ensure best water quality the water reservoir must always be emptied after use. This
procedure removes impurities condensed in the reservoir as result of evaporation. Since the
water in the reservoir is very hot immediately after use, it should be drained only after the water
has cooled down for a few hours after turning the steam generator off. 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. After the tank is completely drained clean the
tank with a household brush and water to remove impurities accumulated inside the tank then
flush the tank with water and close the ball valve by turning its handle clockwise. Do not forget to
refill water before turning the steam generator on again. Do not let the steam generator tank run
dry as an alternative method of draining the water. The lifespan of your combi heater will be
shortened significantly.

1.3.2.

Low water level indication

The combi heater has a low water detection system which reminds you on refilling water before
the steam generator tank runs dry. To avoid the activation of the low water detection system,
refill water once the water level reaches the REFILL mark on the water level indicator tube (about
1.5 litre water left in the tank). Should you miss to refill water at that point, the low water detection
system will automatically turn off the steam generator heater at about 1 litre and display a FILL
message together with a buzzer tone on the external control unit. Observe caution when refilling
water as the steam generator tank is still hot (refer to section 1.3.1). After refilling water, the steam
generator heater turns on again after a short while.
If no water is refilled upon the FILL message appears on the display of the control unit, the steam
generator will turn on again after a few minutes. The FILL message is repeatedly displayed until the
steam generator tank eventually runs dry. The steam generator is turned off automatically right
after the tank dried up. To be able to turn the heater on again, fill cold water in the reservoir, wait
for about 15 minutes and push the reset button at the bottom of the tank (refer to section 1.3.5).
In order to preserve the heating plate and lifespan of your combi heater avoid "dry boiling" of
the steam generator.

1.3.1.

Filling the water reservoir

Water can be poured through the openings of the scent basins or by removing the reservoir cover
first (refer to section 6). Water should be poured carefully to avoid spillage on electric parts of the
steam generator. The maximum capacity of the tank is approximately 5 litres. If water in the tank
exceeds MAX on the level indicator, water from the indicator tube end will spill on the floor.
The water level can conveniently be monitored through the water level tube.

If a FILL message appears on the external control unit cold water shall be poured through the
openings of the scent basins by carefully removing the scent basins, which might be hot. Do not
attempt to remove the cover as it is extremely hot. Be careful with hot water which might splash
through the scent basin openings while refilling.

Before turning on the steam generator, make sure that sufficient amount of water is in the
reservoir. If the steam generator is turned on without water, the steam generator heater will be
turned off automatically after approximately 1 minute. To be able to turn the heater on again, fill
cold water in the reservoir, wait for about 15 minutes and push the reset button at the bottom of
the tank cover (refer to section 1.3.5).
