Alde Compact 3010 Operating Instructions

10
THE HEATING CARTRIDGES
All Compact 3010s are tted with two
230 V heating cartridges with a maximum
output of either 2100 or 3150 W. Select
the heating cartridge output on the control
panel.
Always check that the input fuse of the
vehicle has the correct amperage in
relation to the selected output. Note these
ratings are for the boiler only.
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 circulation pump is required to circulate
the heated glycol uid. There are three
types of circulation pumps. A 12 V circula-
tion pump can be tted in the expansion
tank, a 230 V or a 12 V circulation pump
can be tted on the boiler. If more than
one circulation pump is installed, the
required circulation pump is selected via
the control panel.
The control panel’s room thermostat is
used to control the circulation pump, i.e.
switching on or off, depending on the
heating requirement.
SYSTEM TEMPERATURE
The boiler is set to a system temperature
of 80°C, i.e. the temperature of the glycol
uid as it circulates in the heating system.
AIR CIRCULATION
In order to achieve the best possible result
from the principle of convected heat, it is
important to allow air to circulate freely
under bunks, and behind backrests and
wall-mounted cabinets. If the vehicle has
a tted carpet, ensure that the carpet does
not obstruct the air supply to the radiators.
It is just as important that cushions or
blankets do not interrupt the ow of air
behind backrests and wall cabinets.

Convectors
The glycol content should be checked
before topping up with new liquid. This will
ensure that the concentration of glycol in
the mixture is not too high.
If the uid level in the expansion tank falls
for reasons other than evaporation, please
check all joints, drain cocks and bleeder
screws to ensure that they are not leaking.
If the glycol-water mixture leaks out, rinse
with water and wipe up.
Never allow the heating system to stand
empty of glycol.
FILLING THE SYSTEM WITH
GLYCOL FLUID
NB! Any vessels used to carry the uid
must be spotlessly clean and the pipes in
the system must be free of contamination.
This will prevent the growth of bacteria in
the system.
The system is lled through the expansion
tank, either manually or using the Alde ll-
ing pump which both tops up and bleeds
the system. For manual lling, unfasten
the circulation pump nut (R) and lift the
pump (S) out of the tank. Slowly pour the
glycol mixture into the tank. Bleed the
system. Top up with more liquid if the level
has fallen after bleeding. Bleed a newly-
lled system regularly during the rst days
the heating system is in operation.

MAINTAINING THE HEATING
SYSTEM
Wintercamping
While camping during the winter, ensure
that the ue is kept clear of snow and ice,
since the inlet air to the LPG boiler enters
through the ue. Do not start the LPG
boiler until the ue is completely free of
snow. A ue extension (part no. 3000 320)
for tting on the roof is recommended for
winter camping.
The LPG system
The LPG system should be checked regu-
larly by a professional, who will ensure
that there are no leaks from connections
or hoses.
LPG hoses should be changed accord-
ing to national regulations, maximum of
ve years. Check the date stamp on the
hose. Hose has a propensity to dry out
and crack.
To increase safety, we recommend tting
an Alde leak gauge, type 4071, as close
as possible to the pressure reduction
valve.
The heating system
Regularly check the heating system’s
uid level in the expansion tank. The level
should be about 1cm above the minimum
indicator in a cold tank.
The heating system should be lled 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 mix-
ture should consist of 60% water and
40% glycol. If the heating system will be
exposed to temperatures below -25°C, the
glycol content must be increased, but not
to more than 50%.
Any vessels used for the liquid must be
spotlessly clean, and the pipes in the
heating system must be free of con-
tamination. This will prevent the growth of
bacteria in the system.
The glycol mixture should be changed
every second year, since its ability to
protect against corrosion, for example, will
deteriorate.
