Ensure that correct electrical service is available before
using the immersion heating.
Campsite power supply differences from a range from
6 A to 10 A and 16 A. Hence, before plugging in, check
that the power source is sufcient fused to support the
power consumption needed for the immersion heating.

2kW - 10A Fuse
3kW - 16A Fuse
1:5 HEATING WITH ELECTRICITY
All Alde Compact 3020 heating systems are tted with two 230V heating elements (one 1kW element and one 2kW
element) in total 3kW.
Refer to the control panel instructions (section 2).
When electrical operation is selected on the control panel, the immersion heating elements are used to heat the
heating system. The heating elements and the circulation pump are controlled in the same way as the
LPG operation.
1:6 THE PRINCIPLE OF CONVECTION
Both LPG and electric heating use hot glycol uid to heat the space in the vehicle.
To achieve the best possible result from the heating, 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 convector’s. It is just as important that cushions and blankets do not obstruct and prevent the ow
of air behind backrests. (see Figure 4).
Obstruction of the air supply to convector’s cause poor
or no heating of the vehicle.

Hot water from the boiler is not intended as drinking
water or for preparing food.
Freshwater 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 control can be installed to reduce the risk of
freezing
(part no. 3010 430 or 3010 431).
Always ush the boiler completely before using for the
rst time or if it has not been used for a long period.
There may be a variation between the water tempera-
ture delivered from the heating system and the temper-
ature at the tap due to the length of the pipe.

HOT WATER HAZARD
Hot water at temperatures above 49 °C can cause seri-
ous scalding injuries and in extreme cases even death.
The heating system can deliver hot water at tempera-
tures up to 85 °C.
– For safe operation, use a mixing valve set at
temperature no higher than 48 °C.
1:7 USING THE HEATING SYSTEM
• DOMESTIC HOT WATER
The Alde Compact 3020 heating system can supply domestic hot water using either LPG or electricity.
Please see the control panel instructions (section 2) for details.
• USING ONLY HOT WATER
When only hot water is required (for example during the summer), no settings need to be changed. The heating sys-
tem will handle this function automatically.
Refer to the control panel instructions for details on using hot water.
• AIR CUSHION
The heating system is designed to have an air space, called an air cushion, at the top of the tank. This air cushion is
essential for absorbing pressure surges in the heating system. Always renew the air cushion in the heating system
after 10 days of use.
This can be done by opening the safety/drain valve on the heating system for a few second.
The air cushion allows expansion to take place and helps protect the heating system against pressure surges from the
water pump.
To maintain the air cushion, always renew the air
cushion in the heating system after 10 days of use.
To make hot water with the heating system:
1. Make sure that the vehicles’s water tank is lled up with clean, uncontaminated water or connected to a main
water supply.
2. Fill the hot water tank in the heating system with clean, fresh water. If the heating system is used for the rst time
or if the heating system has not been used for some time, ush it out with water by opening any hot water tap in
the vehicle and allowing approximately 12 liters to run through the tap.
3. Close all taps and start the heating system using the control panel.
