have a cloth or similar positioned near to the
bleed valve to capture any escaping liquid, and
please be aware that any escaping liquid may
be at high temperature.
After bleeding by either method, check that
the pipes and radiators around the vehicle are
heating up. Then top up the expansion tank as
required.
If there are still issues, try the following:
Single-axle caravan:
Stop the circulation pump. Lower the front
of the caravan as far as possible. Leave it in
this position for a few minutes to allow the
air to travel upwards in the system. Open the
bleeder screw at the highest point. Leave it
open until it discharges glycol fluid. Raise the
front of the caravan as far as possible and
repeat the procedure in this position.
Then position the caravan horizontally and
start the circulation pump. Check that the
pipes and radiators around the vehicle are
heating up.
Twin-axle caravan:
The easiest way to bleed the heating system is
to place the vehicle on a sloping surface or to
raise one end of the vehicle using a jack. Bleed
the system as described above.
Fault finding
The boiler does not start
1. No LPG? Incorrect type for conditions?
2. Is the main tap fully 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.
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 a service
workshop.
Operating instructions control
panel 3010 613
Control panel specifications mary vary. If in
doubt please cross referance instructions
supplied by Alde.
Please read these instructions carefully before
using the boiler. For Operating and Installation
Instructions of boiler, please see separate
instruction. These instructions are for the Alde
Compact 3010 boiler fitted in vehicles, boats
and buildings in accordance with CE no. 0845
BP0003, installation in vehicles e500 00005
and EMC e5 03 261.Installation and repairs
may only be carried out by a professional.
National regulations must be adhered to.
1. Starting the boiler
1. The control panel and the boiler are
switched off.
2. To start the boiler, press the On/Off button
and the start-up display is displayed. The
boiler starts with the last selected setting.
Types of glycol
Various types of antifreeze (as used in car
radiators) are available from service stations,
car accessory shops and on line retailers and
these types of antifreeze can be used to top
up or replace the heating system fluid in the
Alde heating system.
Frost and corrosion damage are not covered
under warranty, so it is important that the
type purchased contains corrosion inhibitors
suitable for use with aluminium systems.
Always check the label, ask the retailer for
advice, or check with your supplying dealer
if unsure. Please note the corrosion inhibitor
will have a limited life, and after it expires, the
system will have no corrosion protection.
The fluid will usually be named as Ethylene
glycol, but may also be described as
monoethylene glycol, MEG, ethanediol, or
G12++. There is no industry standard for
the colour of the antifreeze, but as a general
guideline it indicates the type of corrosion
inhibitor:
Blue, Green - Silicate inhibitor, usually offering
2-year corrosion protection
Red, Orange - OAT inhibitor, usually offering
5-year corrosion protection
Purple, Magenta - G12++ Silicated OAT
inhibitor, usually offering 5 year corrosion
protection
It is important that antifreeze containing Silicate
inhibitor (Blue or Green) is not mixed with
antifreeze containing OAT inhibitor (Red or
Orange). To guarantee compatibility, there are
two options:
1. Match the colour, taking care to also check
the label on the antifreeze bottle, i.e. if the
system is filled with blue silicate-containing
antifreeze, top up with blue silicate-
containing antifreeze.
2. Use G12++ antifreeze which is compatible
with any of the other types of inhibitor
described.
Bleeding the system
Depending on the routing of the heating circuit
pipes, 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.
Bleeding:
When bleeding the heating circuit pipes,
please be aware that parts of the system,
including the appliance, pipe work and fluid
within, may be at a high temperature – please
allow the system to cool before bleeding, to
avoid the risk of burns
The appliance mounted circulation pump has
a speed control dial, as shown in the above
image. This can, for a short time only (max
15 minutes) be set at its maximum speed to
assist with removing trapped air. This works
by moving the fluid at an increased speed,
carrying trapped air through the pipe work until
it can escape from the fluid into the header
tank. Before increasing the speed setting,
make a note of the original setting (Typically 2
or 3), and after 15 minutes return the speed
control to that number. Leaving the pump at its
maximum speed setting will eventually cause
damage to the pump, which would not be
covered by your caravan warranty.
If use of the high speed pump setting does
not resolve the problem, a bleeder screw will
be fitted to each high point in the heating
system pipe work. With the circulation pump
switched off, open each bleeder screw and
leave it open until it starts to discharge water
– as with bleeding a domestic radiator, please
