2. Make sure that the boiler is filled with fresh drinking water.

3. Open hot water taps in kitchen, bathroom, shower, etc.

(set pre-selecting mixing taps or single-lever valves to

"hot"). Leave water taps open until water flows out of taps.

The air is pressed out of the boiler in the process and it fills

with water.

If just the cold water supply system is being operated, without

using the boiler, the latter also fills up with water. In order to

avoid damage by frost, the water contents must be drained by

operating the electrical safety/drainage valve (see chapter4.7.1,

"Draining the boiler manually" on page 14), also when the

boiler has not been used.

As an alternative, two shut-off valves, resistant to hot water,

can be fitted in front of the cold and hot water connection.

When connecting to a central water supply (rural or city mains)

or if using a more powerful water pump, a pressure reduction

valve must always be installed to prevent a pressure above 2.5

bar developing in the boiler.

NOTE

Due to pressure differences in the system which result

during filling or operation, small water quantities (ap-

proximately 30 ml / 24 h) can be drained out of the

boiler, however there is no need to be concerned about

complete draining.

6 Maintenance

Correct maintenance of Webasto Dual Top ST integrated heat-

ers is important to ensure years of trouble-free, safe use and en-

joyment.

Take your vehicle to an authorized Webasto dealer for periodic

service and inspection.

It is vital that your Webasto dealer carries out any repair or

maintenance, which is not described in this document. Consult

your dealer for assistance in determining your maintenance

needs.

How much of your vehicle's service and maintenance you can

do yourself, depends on your skill and experience, and whether

you have the special tools required. If you want to learn how to

work on your heater, then ask your Webasto dealer for advice.

CAUTION

Many heater service and repair tasks require special

knowledge and tools.

Improper adjustment or service may result in damage to

the heater, or in an accident, which can cause serious

injury.

• For best performance, your authorised Webasto dealer must

inspect and service your heating system at least every 2 years,

independent of usage.

• DO NOT use high-pressure washer or compressed air to clean

the heater. This can force dirt into areas that may cause dam-

age.

• The heater must be switched "OFF" before cleaning.

• Always disconnect 230 V power supply before any cleaning,

maintenance or repair.

• Drain the water system when the vehicle is stored for a longer

period.

• Use commercial descaling agents for descaling the boiler, this

being introduced into the appliance via the water supply.

See chapter6.2, "Descaling" on page 17.

• Regularly check all components of the water supply system.

6.1 Disinfection

nIn case no water has been taken from the water supply sys-

tem for a period of a week or more, drain the whole water

system and rinse it thoroughly before refilling it.

nTo avoid micro-organisms, water should not stay longer

than a fortnight in the boiler. Disinfect the water supply

system if water was more than a fortnight in the boiler.

nTo prevent any harm, operate the heater full power every

four weeks (diesel powered operation, not the electric

heater):

– for at least 20 minutes continuously, winter mode, heat-

ing cabin without hot water production. This prevents

mechanical parts from seizing.

– followed by operation for at least 30 minutes continu-

ously, “Summer mode 70°C”, hot water production

only. Water supply systems below 60 °C may breed mi-

cro-organisms.

nClean and disinfect the water supply system immediately

before rental or lending of the vehicle.

nClean and disinfect the water supply system at least one

time per year.

NOTE

Before winter storage, it is advisable to completely

drain the water supply system with compressed air of 2

bar. To do this, open all taps, connect the compressed

air to the hot water line and wait until the water has

completely drained off.

A water supply system with a suspected contamination with mi-

cro-organisms has to be disinfected.

1. Clean and disinfect the water supply system according to all

local regulations such as the DVGW W 291 in Germany.

2. Use a solution of Sodium Hypochlorite (NaOCl) in water as

disinfectant. Carefully follow the instructions of the manu-

facturer. Other products may harm your health and/or the

Dual Top ST .

– Carefully follow all instructions of the NaOCl supplier.

– Carefully follow all instructions of the vehicle manufac-

turer.

3. Drain all water contents. See chapter4.7.1, "Draining the

boiler manually" on page 14 .

4. Close all water taps.

5. Fill entire water supply system with NaOCl solution.

6. Select “Summer mode 40°C” to make sure the electrical

safety/drainage valve does not open.

7. Make sure that the boiler is filled with NaOCl solution.

8. Open water taps in kitchen, bathroom, shower, etc. (set

pre-selecting mixing taps or single-lever valves to "hot").

Leave the taps open until the air has been completely

forced out of the Dual Top ST , it is filled with NaOCl solu-

tion and NaOCl solution flows out of the taps. Then close

the taps. Open the taps one by one, not all at the same

time.

9. Leave it on for 1 to 2 hours.

10. Drain all NaOCl solution contents.

11. Repeat the described procedure (step 1 to 8) with fresh

drinking water. Flush the water supply system thoroughly

with fresh drinking water until fully clean and odorless. No

need to leave it on for 1 to 2 hours.
