The Control Panel; The Warm Water Heater; The Heating Cartridge; The Circulation Pump - Alde Compact 3000 92X Manual

THE CONTROL PANEL

The boiler is controlled using sliding
switches on the control panel. The
desired temperature in the vehicle is set
and regulated via the thermostat on the
control panel.
Control panel functions:
A. Heating cartridge switched off.
B. Heating cartridge switched on at
1050 W.
C. Heating cartridge switched on at
2100 W.
D. Heating cartridge switched on at
3150 W, (if the boiler is fitted with
this output setting).
E. LPG boiler switched off.
F. LPG boiler switched on.
G. LED, indicates that the LPG boiler
is in blocking mode (the burner has
not ignited, or has gone out for some
reason).
H. Warm water setting. The circula-
tion pump switched off. The heating
cartridge/LPG boiler is operated by
the boiler's built-in thermostat. Used
when only hot water is wanted.
I. Normal setting. The circulation
pump is switched on and is control-
led by the thermostat on the control
panel. The operation of the heating
cartridge/LPG boiler is controlled by
the boiler's built-in thermostat. Used
when both heating and warm water
is wanted.
J. Permanent setting. The circulation
pump is switched on and runs con-
stantly. The operation of the heating
cartridge/LPG boiler is controlled by
the thermostat on the control panel.
This setting is used in particular
circumstances, mostly during the
winter. Provides an even flow of
heat, but also reduces the hot water
capacity.
K. Knob for setting the desired room
temperature.
L. Index marking for a room tempera-
ture of approx. 22°C.

THE WARM WATER
HEATER
The boiler is fitted with a built-in warm
water heater with a volume of approx.
8.5-litres fresh water. The warm water
heater can produce around 12 litres
of 40°C water per half-hour (at a cold
water temperature of 10°C). If the hea-
ting cartridge is used instead of gas
for heating the boiler, the capacity is
slightly reduced.
Always rinse out the heater before it is
used, particularly if it has not been in
operation for some time.
NB! The hot water is not intended for
drinking or cooking. When the heater is
in continuous use, it should be emptied
approx. once a month, to ensure that a
new air cushion is formed in the heater.
The air cushion is essential for absor-
bing pressure surges in the heater.
For emptying specially-adapted boilers,
as well as any other freshwater sys-
tems in the vehicle, please refer to the
manufacturer's instructions.
NB! The warm water heater should
always be drained of fresh water
when there is a risk of frost and
when the caravan is not in use.
The guarantee does not cover frost
damage.
Draining the heater using the
combined safety/drain valve:
1. Switch off the freshwater pump
2. Open all water taps.
3. Then open the safety/drain valve by
raising the yellow lever (M) to a verti-
cal position.
4. The heater will now drain directly
below the vehicle through the safety/
drain valve hose. Check that all the
water is emptied out (about 7-10
litres). Leave the valve in the open
position until the next time the heater
is used.
NB! Check that the automatic check
valve (N) is open and is allowing air
to enter the heater when it is being
drained, and that the hose (O) is not
blocked.

THE HEATING CARTRIDGE

All Compact boilers are fitted with one
or two 230 V heating cartridges with a
maximum output of either 2100 or 3150
W. Select the heating cartridge output
by sliding the switch on the control
panel to the desired output position.
Always check that the input fuse of the
vehicle has the correct amperage in
relation to the selected output.
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 12 V circulation pump is fitted in the
expansion tank. It circulates the heated
glycol fluid in the heating system. Use
the sliding switch on the control panel
to start the circulation pump. 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. The circulation pump may
also be operated continuously.
(See the control panel section.)
Please note that continuous opera-
tion of the 12 V circulation pump
considerably reduces the service life
of the motor.
SYSTEM TEMPERATURE
The boiler is set to a system tempera-
ture of 80°C, i.e. the temperature of the
glycol fluid as it circulates in the heating
system. The system temperature may
be reduced when required, i.e. if the
warm water becomes too hot.
Lowering the system temperature
Turn the spindle (Q) anti-clockwise. A
quarter turn represents a temperature
reduction of 10°C.
To increase the system temperature,
turn the axle clockwise until it reaches
its maximum position and cannot be
turned any further. The system tempera-
ture is then reset to 80°C.
