Connection To The Heating System; Connection To The Water System - Alde Compact 3020 HE Installation Instructions Manual

5:8 CONNECTION TO THE HEATING SYSTEM

WARNING
BURN HAZARD
VARNING
The heating system reaches high temperatures when running. The heating pipes must be insulated or built in to pre-
vent the driver or passenger from coming in contact with them while operating the vehicle.
AVERTISSEMENT
• The LPG boiler's connection pipe to the heating system (Ø 22 mm) is located on the side of the boiler. The red mark-
WARNUNG
ing is for the outgoing feed pipe (Figure H 22) and the blue for the incoming return pipe (Figure H 26). Use the instal-
ADVARSEL
lation kit with automatic bleeder and automatic circulation stop for fitting to the boiler.
• The drain hose from the bleeder (Figure H 23) must be routed through the floor of the vehicle. Cut the hose
VAROITUS
obliquely at an angle of 30° facing the rear of the vehicle (Figure G).
ADVERTENCIA
NOTICE
AVVERTENZA
If a circulation pump (Figure H 27) is fitted, it must be
WAARSCHUWING
connected to the return pipe.
The rubber connections must be secured with band
clips.

5:9 CONNECTION TO THE WATER SYSTEM

For the in built hot water heater to function in the boiler, it must be connected to the vehicle's freshwater system. The
freshwater connections are placed on the side of the boiler (Figure H 21 and H 25). The blue marking is for incoming
cold freshwater and the red for outgoing hot water.
• A safety/drain valve must always be fitted to the hot water heater. The safety valves are available in two different models
(see the section on installing Safety/drain valve). If the inlet pressure to the hot water heater exceeds 0.3 MPa (3 bar), a
pressure reducing valve must be installed. The pressure reducing valve must be set to a maximum of 0.3 MPa (3 bar)
and have a minimum capacity of 500 cm
• A non-return valve should also be installed between the water pump and the hot water heater to prevent hot water
from running back into the water tank.
THE HOT WATER HEATER
Always rinse through the hot water heater the first time it is used. It is also OK to use the boiler without freshwater in
the heater.
NOTICE
The freshwater in the heater should always be drained
when there is risk of frost, otherwise there is a risk of
damage due to the boiler freezing. The warranty does
not cover frost damage. A frost guard can be installed
to reduce the risk of freezing
WARNING
SCALDING HAZARD
VARNING
Remember, water in the water heater may be hot.

WARNUNG
EMPTYING THE HOT WATER HEATER
ADVARSEL
1. Switch off the freshwater pump.
2. Open all water taps.
VAROITUS
3. Then, open the safety/drain valve by moving the yellow lever to the vertical position (M) (Figure I), or, alternatively,
ADVERTENCIA
turn the knob (K) 90° (Figure J). The hot water heater will now drain straight out under the vehicle through the
safety/drain valve hose.
AVVERTENZA
4. Check that all the water empties out (approx. 7-10 litres). Leave the valve in the open position until the next time
WAARSCHUWING
the heater is used.
NOTICE
Ensure that the automatic check valve
(see figure H 21) is open and is allowing air to enter the
boiler when it is being drained and that the hose is not
blocked.

CAUTION
OBSERVERA
Pipes, joints or water storage tanks made of copper
should not be used in the heating system. It is best to
ATTENTION
use aluminium pipes only. Do not use different metals
VOORZICHTIG
because this can cause serious corrosion damage.
NOTICE
Hot water from the boiler is not intended as drinking
water or for preparing food.
WARNING
SCALDING HAZARD
VARNING
Never actuate the drain valve lever as long as the heat-
ing system is under water pressure and/or is still warm.
