Operation in frost conditions

(Ambient temperatures below 4 °C)
Risk of damage in frost conditions.
In frost conditions, ambient temperatures below 4 °C, there
is a risk that water in pipes, taps and appliances could freeze.
This can cause considerable damage.
• If the appliance is not to be used in frost conditions, you
must winterise the appliance. Refer to "Winterising the
appliance" on Page 11.
• Winter operation will not protect the RV's entire water
system. Water lines, taps, water tanks and the external
water valves and the vehicle must be heated separately.
• The RV must be designed for winter use/freezing
conditions.
• The water pipes in the RV must be ice-free to operate the
AquaGo in winter. Otherwise, there is no water flow and
the appliance does not start.
When the vehicle is standing, to -20 °C
• The appliance has a built-in thermostat that will start the
burner and the circulation pump whenever the temperature
in the appliance falls below +5 °C. The burner will automati-
cally shut off when it senses a temperature above 44 °C.
• For the appliance to operate properly, you
must ensure a constant supply of power (12 V), propane
gas, sufficient water in the system. You must leave the ap-
pliance powered "ON". The operating mode must be "ECO"
or "COMFORT". The water system must be bled so that the
circulation pump works.
• If the vehicle is standing and ambient tempera-
tures are below -20 °C, the appliance must not be operated
and must be winterised. To winterise the appliance (refer to
"Winterising" on Page 11).
While driving (or if there is no gas supply), to -20 °C
• Gas must not be used for heating while the ve-
hicle is in motion. Ask your dealer / vehicle manufacturer
about options for heating your RV while driving.
• An electric antifreeze kit is available as an accessory (ask
your dealer). With this kit, the appliance can be kept frost-
free while you are driving or if there is no gas supply (to
ambient temperatures of -20 °C). The electric antifreeze kit
includes detailed instructions.
– While the vehicle is in motion and at ambi-
ent temperatures below -20 °C the appliance must not be
operated and must be winterised. To winterise the appli-
ance (refer to "Winterising" on Page 11).

Winterising

Severe damage to the water system components and
the appliance!
Any damage caused by freezing or an unsuitable winteris-
ing fluid will not be covered by warranty.
• Follow the recommendations below if the appliance will
be stored under freezing conditions or for an extended
period of time.
• Winterise the appliance at the start of the winter season
or before travelling to a location where freezing conditions
are likely.
If your RV is equipped with a bypass around the appliance,
separate the appliance from the water system with the
bypass.

Winterising the appliance

To winterise the appliance, you must drain all water from the
appliance. To do this we advise the following steps:
• Remove the water inlet filter or heating cartridge. See
"Draining the water and cleaning the water inlet filter" on
Page 13, steps 1 to 8.
• Let water completely drain from the appliance. This can
take several minutes.
• Do not insert the water inlet filter or heating cartridge into
the appliance during winter – if the appliance is not used.
• Danger of crushing/pinching of fin-
gers when the Easy Drain Lever is closed! Never put
fingers between the Easy Drain Lever and latch.
• Close the Easy Drain Lever and the access door.
Once the water has been drained, the appliance is protected
against freezing conditions.

Winterising the RV with a winterising fluid

• Winterising the RV with a winterising fluid is only
possible with an installed bypass kit (not in scope
of delivery)
• Refer to the connection diagram "Connection di-
agrams" on Page 22 for all letters referred to in
the following description.
