6. INSTALLATION CHECKS
The LPG system
WARNING
FIRE/EXPLOSION HAZARD
VARNING
A naked flame must not be used when looking for leaks.
AVERTISSEMENT
• After installation or servicing, always check the LPG installation for leaks in accordance with current regulations.
WARNUNG
If there is leak, localise it with leak detector spray or soapy water.
• Check that the reducing valve is at the right pressure (30 mbar).
ADVARSEL
The heating system
VAROITUS
• Check that all hose clips are fitted and correctly placed.
ADVERTENCIA
• The heating system must be checked for leaks when the entire system is visible, i.e. before fitting the furnishings.
Checks can be performed in two ways. Either leak detection with 0.75 - 1.0 bar for 15 minutes, maximum 0.05 bar
AVVERTENZA
pressure reduction, or fill the system with fluid and perform a visual check. No fluid leak is acceptable.
WAARSCHUWING
heck the glycol fluid level in the expansion tank: the level should be approx. 1 cm above the MIN line when the
• C
system is cold. Ensure that the system is properly vented before it is put into operation.
• Check that the circulation pump's speed is set correctly. See section 10 Installation of pumps. If the fluid in the
expansion tank gurgles and makes a noise, the pump speed is set too high; lower the speed of the circulation pump.
• Check that the boiler can be started on both gas and electricity.
• Ensure satisfactory heat comfort and circulation in the heating system.
Water system
• Leak test the freshwater system and the boiler. Carefully check that all connections between boiler and water
system are watertight.
Miscellaneous
• Check that the bleed and drain hoses on the expansion tank are not blocked.
• Check that the emptying of the freshwater system is working (see section Connection to the freshwater system).
• Check that flue and hoses are in position and that hose clips are fitted and tightened.
• Check that the serial number and installation date have been entered into the boiler's servicing logbook.
• Check that the year on the boiler's rating plate has a cross against it (when installing the boiler or on initial start-up).
• Check that all accessories for the heating system are working, and are set correctly, under "Installed Accessories" in
Alde's control panel. For example, booster, under floor heating, engine heating and load monitor.
• If Truma AC is fitted and connected to Alde Compact 3020 HE, check that the AC can be started from Alde's control
panel.
• Check the air circulation. Make sure there are no obstructions preventing air circulation (convection). In order to
exploit the water-borne heating to the full, it is important that air can circulate freely under bunks, and behind back-
rests and wall-mounted cabinets. If the vehicle has a fitted carpet, for instance, ensure that the carpet does not
block the air supply to the convectors. It is equally important that cushions and blankets do not obstruct and prevent
the flow of air behind backrests.
7. THE FIRST TIME THE HEATING SYSTEM IS STARTED.
• Start the boiler according to section 3 in the operating instructions for the Alde Compact 3020 HE.
• Select language, this appears when the panel is started for the first time, see section 2:11 point 22 in the operating
instructions for the Alde Compact 3020 HE.
• Check that the right accessories are ticked off in the list of installed functions, see section "2:15 Activation of in-
stalled functions" in the operating instructions for the Alde Compact 3020 HE.
• Set the clock, see section 2:11 point 4 in the operating instructions for the Alde Compact 3020 HE.
• Set the desired operating mode (gas and/or electric) and the desired interior temperature, see sections 2:4, 2:5
and 2:6 in the operating instructions for the Alde Compact 3020 HE.
The LPG boiler and immersion heaters can be operated simultaneously, but this should be avoided in newly
filled systems, risk for overheating.
