Note:
All Alde systems are installed and
bled during the manufacturing stage to the
requirements of Alde UK. However, further
bleeding may be required after the first few
operations of the system.
BLEEDING THE SYSTEM
Depending on how the pipes have been fitted,
air pockets may form when the system is filled
with glycol fluid.
A sign that there is air trapped in the system
is that the heat released into the pipes only
extends a metre or so from the boiler even
though the circulation pump is operating.
In newly-filled systems, small air bubbles
can form in the expansion tank, creating a
murmuring sound. If the circulation pump is
stopped for a few seconds, the bubbles will
disappear.
Bleeding:
The boiler is fitted with an automatic bleeder,
valve to bleed air out of the boiler. Start the
LPG boiler. The circulation pump should be
switched off.
Open the bleeder screws in the system (please
refer to the motorhome technical book for their
locations). Leave the bleeder screws open until
they start discharging fluid, and then close
them. Start the circulation pump and let it run
for a while. Check that the pipes and radiators
around the vehicle are heating up.
If they still fail to heat up, try the following:
To help bleed the remaining trapped air place
the vehicle on a sloping surface with the front
end downwards. Then open the bleed screw
at the highest point at the rear until it starts
discharging fluid, then close the the bleed
screw. Turn the vehicle around and bleed the
highest point at the front.
FAULT FINDING
The boiler does not start
1. No LPG? Incorrect type for conditions?
2. Is the cylinder valve and gas shut off valve
on the manifold open?
3. If the boiler has not been operated for
some time, or if the gas cylinder has been
changed, it may take longer than normal
to light the boiler.
4. Check that the boiler is connected to the
electricity supply (> 11V).
5. Check that the fuse (T) for the boiler
is intact (See fuses on page 71).
6. Check whether the electric connections on
the boiler are securely in position.
If none of the above helps, contact a
service workshop.
The heating cartridge is not working
1. Check that there is an electricity supply
(230V ~) to the heating cartridge.
2. Check that the relays fitted to the boiler
come on (a slight click can be heard from
the relays when the heating cartridge is
switched on at the control panel).
If none of the above helps, contact your dealer
or Alde - See page 9 for contact numbers.
