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. 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 fluid 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 Ethylene Glycol
fluid
Note: Any vessels used to carry the fluid
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. Do not use water from the caravan’s
fresh water tank; residual tank cleaning
chemicals can cause corrosion.
The system is filled through the expansion
tank, either manually or using the Alde filling
pump which both tops up and bleeds the
system. For manual filling, first remove the
Grey plastic collar which sits at the top of the
expansion tank cover, by squeezing each side
to release it from the plastic below. Once this
is removed unfasten the nut (R) and remove
the nut, and rubber cap below, from the top
of the tank. Slowly pour the glycol mixture into
the tank. Fill to half way between Min – Max
when cold. Bleed the system. Top up with
more liquid if the level has fallen after bleeding.
Bleed a newly filled system regularly during the
first days the heating system is in operation.

The heating cartridges
All Compact 3010s are fitted with two 230V
heating cartridges with a maximum output
of either 2100 or 3150W. Select the heating
cartridge output on the control panel.
Always check that the input supply of the
vehicle has the correct amperage in relation to
the selected output.
Note these ratings are for the boiler only.
1050W requires a 6 amp fuse/supply.
2100W requires a 10 amp fuse/supply.
3150W requires a 16 amp fuse/supply.
The circulation pump
A circulation pump is required to circulate the
heated glycol fluid around the heating circuit.
A 12V circulation pump is mounted to the
appliance.
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.
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.
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 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 not interrupt the flow of air behind
backrests and wall cabinets.
Note: During the first weeks of ownership
customers may notice a drop in the glycol
level and/or blocked radiators. This is normal
as the system settles.
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. 3000 320) for fitting on the roof is
recommended for winter camping.

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 50% water and 50% 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 contamination. This will
