Fitted Equipment
1050 W requires a 6-amp fuse.
2100 W requires a 10-amp fuse.
3150 W requires a 16-amp fuse.
THE CIRCULATION PUMP
A 12 V circulation pump is fitted in the
expansion tank. It circulates the heated
glycol fluid in the heating system. Use the
sliding switch on the control panel to start
the circulation pump. The room thermostat
on the control panel controls the circulation
pump, i.e. switches it on or off according to
the amount of heat required. The circulation
pump may also be operated continuously.
(See the control panel section.
Please note that continuous operation of
the 12 V circulation pump considerably
reduces the service life of the motor.
SYSTEM TEMPERATURE
The boiler is set to a system temperature of
80°C, i.e. the temperature of the glycol fluid
as it circulates in the heating system. The
system temperature may be reduced when
required, i.e. if the warm water becomes too
hot.
Lowering the system temperature
Turn the spindle (Q) anti-clockwise. A
quarter turn represents a temperature
reduction of 10°C. To increase the system
60
temperature, turn the axle clockwise until it
reaches its maximum position and cannot be
turned any further. The system temperature
is then reset to 80°C.
AIR CIRCULATION
In order to achieve the best possible result
from the principle of waterborne heat, it is
important to allow air to circulate freely
under bunks, and behind backrests and
wall-mounted cabinets. If the vehicle has a
fitted carpet, ensure that the carpet does not
obstruct the air supply to the radiators. It is
just as important that cushions or blankets
do no interrupt the flow of air behind
backrests and wall cabinets.
MAINTAINING THE HEATING SYSTEM
Winter camping
While camping during the winter, ensure that
the flue is kept clear of snow and ice since
the inlet air to the LPG boiler enters through
the flue. Do not start the LPG boiler until the
flue is completely free of snow. A flue
extension (part no. 300 320) for fitting on the
roof is recommended for winter camping.
The LPG system
A professional, who will ensure that there are
no leaks from connections or hoses, should
check the LPG system regularly. LPG hoses
should be changed every second year, since
their propensity to dry out and crack will
eventually result in leaks.
To increase safety, we recommend fitting an
Alde leak gauge, type 4071, as close as
possible to the pressure reduction valve.
The heating system
Regularly check the heating system's fluid
level in the expansion tank. The level should
be about 1cm above the minimum indicator
in a cold tank.
The heating system should be filled with a
mixture of water and glycol. For preference,
use high quality ready-mixed glycol (with
inhibitor) intended for use in aluminium
heating systems. If using concentrated
glycol, the mixture should consist of 60%
water and 40% glycol. If the heating system
