Draining The Water Heater; Maintenance; Fuses; Disposal - Truma Combi 4 Gebrauchsanweisung

Draining the water heater

Switch off power to water pump (main or pump switch).
Open hot water taps in kitchen and bathroom.
Turn the rotary switch on the drain valve (FrostControl) by 180°
until it engages, whereby the push button moves out and the
drain valve opens.
The boiler is now drained directly to the outside via the drain
valve. Place a bucket beneath the outlet to check whether the
water content has completely drained away (10 litres). There
shall be no claims under guarantee for damage caused
by frost!

Maintenance

Only original Truma parts may be used for maintenance and
repair work!
We recommend the Truma system care set for cleaning, dis-
infecting and looking after the boiler. Other products – in par-
ticular products containing chlorine – are unsuitable.
The effectiveness of the use of chemicals to combat microor-
ganisms in the unit can be increased by heating the water in
the boiler to 70 °C at regular intervals.
Move the rotary switch on the control panel to position (c –
summer operation) 60 °C. The green (b) and yellow (g) LEDs
light up.
Once the water in the boiler has reached a temperature
of 60 °C, the burner will switch off and the yellow LED (g)
will go out. The unit must stay switched on for at least 30 min-
utes and no warm water may be removed. The residual heat in
the heat exchanger will heat the water up to 70 °C.

Fuses

The unit's fuse is located on the electronics under the connec-
tion cover. Replace the unit's fuse only with an identical fuse.
Device fuse: 10 A – slow – (T 10 A)

Disposal

The device must be disposed of in line with the administra-
tive regulations of the respective country in which it is used.
National regulations and laws (in Germany, for example, the
End-of-life Vehicle Regulation) must be observed.
In other countries, the relevant regulations must be observed.
