OPERATING INSTRUCTIONS ALDE COMPACT 3020 HIGH EFFICIENCY
1. CHECKING THE HEATING SYSTEM BEFORE USE.
• Check the glycol uid level in the expansion tank. It should be approx. 1 cm over the min line when
the system is cold. Air bubbles may occur in new vehicles that will disappear when you start using the
system and then the level in the expansion tank will decrease.
Warning! The boiler must not be started if there is no ethylene glycol uid in the system.
Warning! Do not mix different types of glycol as this could cause the glycol uid to coagulate.
Refer to section 12 for more information on glycol uid.
• Ensure that the ue is kept clear of snow and ice, etc., as the intake air to the boiler enters through
the ue during LPG operation. Also check that no other objects are hindering or disturbing exhaust and
supply air from the ue.
Tip! A ue extension (part no. 3000 320) is available for the roof ue that is recommended for camping in winter.
Warning! Make sure the ue does not end up in a conned space, e.g. the awning, as this can
lead to risk of carbon dioxide poisoning.
• Check supply and exhaust air intake, the vehicle is often equipped with supply and exhaust air valves
(refer to vehicle instructions) that must not be blocked as this will impair the efciency of the heating
system and air quality, which can lead to carbon monoxide poisoning.
• Check air circulation, make sure there is nothing preventing air circulation (convection). In order to
exploit the water-borne heat design to the full, it is important that air can circulate freely under bunks and
behind backrests and wall-mounted cabinets. If the vehicle has a tted carpet, ensure that the carpet
does not obstruct the air supply to the convectors. It is just as important that cushions or blankets do not
obstruct and hinder the air circulation behind backrests.
2. THE FIRST TIME YOU START THE HEATING SYSTEM.
• Hot water heater Always ush the water heater before using for the rst time or if it has not been used
for a long period. Then ll the water heater with water, refer to separate instructions for the vehicle. The
boiler can equally well be used without any freshwater in the heater.
NB! Hot water from the boiler is not intended as drinking water or for food making.
Warning! Fresh water in the heater should always be drained when there is risk of frost or there
is a risk of the boiler freezing. The warranty does not cover frost damage. A frost guard can be
installed to reduce the risk of freezing.
NB! Note that the water in the water heater can be hot.
• Carry out a check as in item 1 (Checking the heating system before use).
• Start the boiler as described in section 3.
• Set the clock, refer to section 7:1 item 2.
• Once the heating system has been started for the rst time or when accessories have been installed,
ensure the correct accessories have been checked in the list of installed functions, refer to section 11.
• Set the desired operating mode (gas and/or electric) and the desired interior temperature, refer to sec-
tions 5:1, 5:3 and 5:4.
The LPG boiler and electric elements may be operated simultaneously.
