ELECTRICAL CONNECTION
12 VOLTS DC
Connect the cable (E 34) between the
control panel and the LPG boiler.
NB" If the heating system is empty of " uid,
wait before connecting the 12 V supply to
the boiler. This is to ensure the boiler is
not started up without " uid in the system
by mistake. The cable must not be exten-
ded. Only use original Alde cables, which
are available in various lengths.
The 12-volt supply to the boiler must be
routed directly from the battery via the
vehicle's main switch (E 35) or a separate
switch (the boiler draws about 70 mA
when it is in standby or switched off).
A 5-amp fuse (E 36) must be ! tted close
to the battery. The positive and negative
cable between the battery and the boiler
must have a cable section of 1.5 mm2 if it
is equal to or less than 20 metres in length
(10 m for the positive cable and 10 m for the
negative cable). On longer cables, the cable
section should be increased to 2.5 mm
If a transformer is used instead of the
battery, it must be of good quality, produ-
cing constant direct current as opposed to
pulsating direct current.
The electrical connection from the boiler
to the circulation pump in the expansion
tank must be made using a two-core
cable of at least 0.5 mm2 cross section
(maximum cable length of 6 m). On longer
cables, cable of 0.75 mm2 cross section
should be used. Fit the cable to the two-
pole contact and connect to the boiler's
contact (E 38) and to the circulation
pump's contact (E 39).
NB"
Do not clamp 12 V cables or sensor
cables together with 230-240 V cables.
It is best not to position the cables close
to one another. If the cables are bundled
together, there is a greater risk of malfun-
ction during operation.
230-240 VOLTS
The boiler (electric element) must be
connected securely to a 230-240 V supply
and be protected with a 10 A fuse in the
case of a 2 kW electric element and a
16 A fuse for a 3 kW element. The boiler
must be connected to a protective earth.
It must be possible to disconnect the
power to the boiler, either via an easily
accessible plug or via an omnipolar circuit
breaker. The installation must be executed
by a quali! ed person according to current
national regulations. Only original connec-
tion cable from Alde should be used.
WARNING: 230-240 V must be kept
separate from 12 V DC.

FILLING THE HEATING
SYSTEM
The heating system should be ! lled with
a " uid mixture made up from water and
ethylene glycol. For best results, use high-
quality ready-mixed ethylene glycol (with
inhibitors) intended for use in aluminium
2
.
heating systems. The proportions when
using concentrated ethylene glycol are
60% water and 40% ethylene glycol. If the
heating system is likely to be exposed to
temperatures below -25°C, the ethylene
glycol content must be increased, but
should not exceed 50%.
Any vessels used for handling or mixing
the liquid must be spotlessly clean, and
the pipes in the heating system must be
free of contamination. This is to prevent
the growth of bacteria in the system.
The system is ! lled via the expansion
tank, either manually or using the Alde
! lling pump, which both tops up and
bleeds the system. When ! lling manually,
the " uid must be poured in slowly until
the level is about 1 cm above the MIN
mark on the tank. Bleed the system. Top
up with more " uid if the level has fallen
after bleeding. Bleed a newly ! lled heating
system regularly during the ! rst days it is
in operation.
For general care of the heating system,
see the user instructions.
INSTALLATION CHECKS
The LPG system
• After installation or servicing, always
check the LPG installation for leaks in
accordance with current regulations.
If there is leak, localise it with leak detec-
tor spray or soapy water.
NB" A naked " ame must not be used
when looking for leaks.
• Check that the reducing regulator is at
the right pressure (30 mbar).
For still greater safety, we recommend
that an Alde LPG leak detector be ! tted.
This should be ! tted close to the redu-
cing regulator. You can then easily check
whether the installation is leaking simply
by pressing a button.
The heating system
• The heating system should be checked
for leaks when the entire system is visible,
i.e. before ! tting the decorative covers.
Checks can be performed in two ways.
Either leak detection with 0.75 to 1.0 bar
for 15 minutes, maximum of 0.05 bar
pressure reduction, or ! ll the system with
" uid and perform a visual check. No " uid
leak is acceptable.
• Check that all hose clips are ! tted and
correctly located.
Miscellaneous
• Check that the bleed and drain hoses on
the expansion tank and the drain tap for
hot water are not blocked.
• Check that " ue and hoses are in position
and that hose clips are ! tted and tight.
• Check that the boiler's servicing log has
had the serial number and installation
date entered in it.
• Check that the year on the boiler's rating
plate has a cross against it (when instal-
ling the boiler or on initial start-up).
