The caravan boiler must be mounted on a solid base plate with four
screws. Use suitable screws or other mounting systems for your base
plate. Optionally, the boiler can also be mounted vertically on a stable
wall.

• Relatively low heat losses
• 8 litres of hot water
• Slightly more heat loss
• 9.5 litres of hot water
The boiler was heated up to 65 °C. It was drained
at about 5 litres per minute. From a water tempe-
rature at the shower head of 35°C until the water
was 35°C again, the volume was measured.

For safety reasons, the non-return/overpressure valve supplied must
be connected to the cold water inlet of the boiler.
The supplied drain plug must be connected to enable draining. This
can be done using the T-piece provided, as shown in Figure 1.
We recommend integrating the caravan boiler into a water system as

The water in the boiler must not freeze. Frozen
water in the boiler can cause damage or a defect
in the appliance. If necessary, the contents of the
boiler can be drained via the non-return/overpres-
sure valve and the drain plug. Proceed as follows:
• Ensure that any water that leaks from the
non-return/overpressure valve and the drain
plug can drain away safely. This is important to
prevent possible water damage.
• Disconnect the water heater from any live
electrical wiring.
•
• Open the drain plug using the vent key provi-
ded.
• Tilt the small lever of the check/relief valve 90 °.
• The water should now drain away. Drainage is
complete when no more water comes out of
the valves.
• Small amounts of water remain in the boiler
cause any damage.
Drainage
The draining water can be hot - risk of scalding!
These steps do not ensure complete emptying of the water tank.

The boiler is heated with photovoltaic electricity. This mode
should be selected if there is an external energy management
(e.g. solar charge controller with deep discharge protection)
which releases the power for the boiler.

Be sure to carefully read the instructions and war-
nings in this manual before installing and operating
the water heater. The information contained in this
manual is intended to familiarize you with the water
heater, the rules of its correct and safe operation,
and the minimum requirements for its maintenance
and servicing. Furthermore, you are obliged to make
will install and potentially repair the appliance. The
of its functionality is not within the distributor's
warranty obligation nor the manufacturer.
These instructions should always be kept near the
appliance for future reference. Compliance with the
rules here described is part of the measures for the
safe use of the product and is considered part of the
warranty conditions.
WARNING!
There is a risk of burns or scalding when
using the appliance!
WARNING! This device can be used by children
from the age of eight and also by people with a lack
of experience and knowledge or reduced physical,
sensory or mental abilities, if they are supervised or
have been instructed in the safe use of the device
and understand the resulting dangers. Children
must not play with the device. Cleaning and user
maintenance shall not be made by children without
supervision.
IMPORTANT!

provided or recommended by the manufacturer, as
well as all other assemblies, are UNCONDITIONALLY

IMPORTANT!
water before connecting it to the electrical sup-
ply! Failure to comply with the electrical connec-
whereby the water heater must not be operated.
IMPORTANT! Observe the maximum permissible
pressure (see chapter: Technical data).
• The device is under pressure. Expansion water
may drip out of the pressure relief valve during
heating.
• Operate the pressure relief valve regularly to
prevent it from getting stuck, e.g. B. to prevent
limescale deposits.
• Install a type-tested pressure relief valve in the
cold water supply line. Note that depending
on the pressure of the supply line, a pressure
reducer may also be required.
• Attach a drain line to the opening of the relief
valve, with an even slope to the drain.
• Dimension the drain line so that the water can
drain unhindered when the overpressure valve
is fully open.
• The opening of the pressure relief valve must
not be blocked.
• This device contains rechargeable batteries
which are not replaceable. However, their de-
fect does not limit the basic functionality.
• The device may be operated up to an altitude of
4000 m above sea level.
• The device owner is responsible for preventing
possible damage due to lightning strikes and
for proper installation of the PV modules with
lightning protection.
Technical data
This water heater can provide hot water from the
mains water supply or other pressure-operated
water supply for several consumers at the same
time. The water used for heating must meet the
requirements of the normative documents for ser-
vice water, in particular: chloride content up to 250
mg/l; electrical conductivity more than 100 µS/cm,
pH value 6.5 - 8 for hot water tanks with enamelled
water tank. The thermal insulation consists of CFC-
free polyurethane foam.
The maximum electrical output of the hot water sto-
rage tank is 550 W. The actual output of the heating
elements depends on both the connected photovol-
taic output and the intensity of the sun's radiation.
The water is heated to a maximum of 65 °C to ensure
protection against scalding. Detailed information
can be found on the data sheet or the nameplate.
The hot water storage tanks are equipped with a
combined non-return and pressure relief valve,
which prevents the water from being over-pressu-
rized while the device is in operation. The water
tanks are made of steel with a high-strength enamel
coating and additional cathodic protection with a
magnesium anode.
Always install the water heater lying down, in a dry
assembly as well as for the wall. Make sure that the
forces that act on the boiler or its mounting system
when driving. When choosing a suitable substrate
for the hot water storage tank, the following must
be taken into account:
• Type and material
• Dimensions of the device,
• Type of fastening
•
• Arrangement of water and electricity lines
• Degree of protection against water splashes
The installation site must comply with the requi-
rements of the water and electrical installation.
