Item no. 141800-141832, 141800T- 141832T

Installation instruction
MA45-11E
2012
The electric heater must be installed horizontally as shown on the drawing, so that it is always full of water. The heater must never be
started or left switched on unless it is completely full of water (fire risk).
If the heater is positioned against combustible material, a fireproof panel or similar must be placed between the heater and the wall.
The panel must extend 10 cm outside the outer dimensions of the heater.
Do not cover the heater.
The warranty is void if the heater has been incorrectly installed or used.
Important!
The standard heater must not be used in aggressive water, salt water or for pools with a chlorinator/salt generator.
In such circumstances an Electric heater Aqua HL line titanium is required.
“Persons with limited physical or mental capacity (including children) must not use the device without instructions on how to use it
safely”, according to IEC 60335-1.
Pipe installation
The heater must be installed in the return line to the pool after
the filter; see the installation drawing.
Do not install a shut-off valve between the heater and the pool. If a valve is required, install a check valve. If there is a risk of freezing
where the heater is located, the installation must allow all water to be drained from the heater.
The outlet of the electric heater must not be connected to any tap or coupling other than in accordance with the installation drawing.
Electrical installation
The electrical installation work must be done by a qualified electrician.
The pipework must be complete before the electrical installation work is done.
Connect the motor protection auxiliary relay of the circulation pump to P1:1 and 2, see the enclosed wiring diagram for voltage and
number of phases. When the motor protection is switched on, the circuit shall be closed.
If there is no external motor protection the connections 1 and 2 on P1shall be interconnected (clamped).
Check that the connecting cable cannot come into contact with the hot parts of the element.
Starting
1. Start the pool water circulation pump.
Check that the water is circulating normally in the installation before switching on the heater. The heater must be completely full of
water before the power is switched on.
2. Switch on the power to the heater.
3. Set the desired pool temperature.
4. Check the flow switch by turning off the flow of water through the heater with a shut-off valve. The contactor should trip.
5. Turn on the water. The contactor should now close (after 15 sec.).
6. The heater will now heat the pool water to the desired temperature.
Setting the temperature
Press once (on the blue or red arrow key) - the display starts to flash.
Press once more - a temperature is now displayed.
Change the temperature up and down with the arrow keys until the required temperature is set.
Red = warmer, blue = colder in steps of 0,5°C.
After the setting is completed, the display will return to showing the actual pool temperature with a fixed light.
Operation
For the heater to work, the pool water must be circulating.
The yellow LED marked “Heating” is lit when the heater is working and goes out when the correct temperature has been reached.
The display constantly shows the current temperature of the water. The set temperature can be changed at any time (see Setting the
temperature). To see the set temperature, press once (the display flashes). NOTE: The set temperature is retained in the memory after
a power failure.
NOTE: Always switch off the power to the heater before backwashing and before cleaning the filter.
Trouble shooting
If the heater does not start:
1. Check the fuses
2. The overheating protection may have tripped:
-Losen the protective cap, see fig beside.
-Press the reset button on the connection box.
-Put the cap back.
3. Check the flow rate. The flow switch in the heater is
designed for a minimum flow of 90 litres/min.
4. Set the thermostat to a higher temperature.
