Installation

Pipe routing shall always performed before the electrical installation.

Position the heater so that the front and top can be opened. Install the connections so that the heater can be easily moved for

inspection, cleaning and service.

A non-return valve must be installed AFTER the heater and a shut-o valve BEFORE the heater to allow servicing the heater

without needing to empty the pool.

A by-pass should be installed and adjusted so that the recommended ow through the heater can be attained.

Mount the heater on the oor/foundation with screws/bolts through the four Ø9 mm holes in the bottom.

Pipe installation

Connect the heater to the pool system according to the ow diagram below. The outlet must not be connected to any other type

of tap or connection than those given.

The electric heater has a G2¾” connection for glued attachment of Ø63 mm outer diameter PVC piping.

NOTE! Do not t a shut-o valve between the heater and swimming pool (t a non-return valve instead).

Mixing of chlorine, acid or similar in the pool water must always be performed AFTER the heater, to avoid corrosion.

Electrical installation

• The electrical installation must be performed by an authorized electrician and in accordance with the instructions included

with the heater.

• A main switch must be tted before all of the heater’s electrical connections (L1, L2, L3). This must be a multi-pole switch that

fulls the demands of IEC/EN 60335-1 sections 7.12.2, 22.2, 24.3.

• We recommend the installation of a residual current device.

• Connect the heater in accordance with the connection drawing, see pages 13.

• The control voltage is connected to connection block L1 and N.

Note that the control voltage must be equipped with separate 5 –10 Ampere fuse for the electrical connections (L1, L2).

• The heater must be installed in such a way that it cannot be activated unless circulation pump (sucient ow) is operational,

i.e. the control voltage to the heater’s contactor must be interlocked via the pump’s contactor.

• Do not connect the heater to an incorrect power source. Contact the local electrical utility for the correct power source.

• The voltage to the heater may not vary by more than +5% to –10% with respect to the model and rating plate specication.

• The input cabling FOR THE CONTROL CIRCUIT must always be fused for 5 –10A.

• The input cabling FOR THE CONTACTORS shall be fused in accordance with the table for the operating voltage in question,

see gure 5.

The input cabling for the contactors (K1A-K4A) shall be connected according to the electrical drawing in the way shown in

gure 4 below.

NOTE! It is important that the screwdriver has the correct dimensions, and is pushed into the correct hole in the

correct way.

Starting up

Start

1. Check the electrical connections and pipe routing. Turn on all external fuses.

2. Open all the valves except the drain valve and ll the system with water.

- If the water level in the pool is lower than the heater, ll the pool with the heater turned o (switch in position O).

- If the system has a by-pass, open the by-pass valve half way. Make nal adjustments later.

3. Start the the system pump to ll the system with water.

Temperature setting

4. Turn the switch on the electrical heater ON.

5. Set the desired pool temperature (°C) by turning the thermostat knob.

6. If the ow of water is correct and the pool water temperature is lower than the setting, heating element 1 and 2 will start with

approx 20 seconds delay to heat the water and the green “operating” lamp will light up. If the electrical heater has more than

two heating elements, no.3 will start after an additional 5 seconds and no.4 approx 5 seconds after that. This is to avoid

overloading the power supply.

7. Check that water temperature in the pool after a while and make any ne adjustments to the thermostat.

Water ow/Bypass adjustment

The water ow is adjusted using a valve (item 22, gure 2) on the by-pass.

Adjust the by-pass valve so that the ow through the electrical heater is between 170 – 300 l/min. To prevent unauthorized

adjustment, operating problems or damage to the electrical heater, we recommend that the handle of the by-pass valve is

removed once nal adjustment has been made.

Maintenance

Note that the electrical heater only operates when the water in the system is circulating. It should not operate if the circulation

pump is turned o or if the desired temperature has been reached.

If the water in the system is stationary for more than a week, the heater should be drained of water.

If there is a risk of freezing, the power to the electrical heater and cirkulation pump must be turned o and the heater drained of

water, see “Draining the heater” below.

When reverse ushing and cleaning the pool system’s lter, the electrical heater must be turned o.

In areas of very hard water, the immersion heaters can accumulate a coating of calcium after a long time, which reduces the

power of the electrical heater and the life of the immersion heaters. In such cases, contact an authorized electrician who can

perform a regular inspection of the immersion heaters and remove any such coating when necessary.

Draining the heater

1. Turn o the electrical heater and turn o the main switch before draining.

2. Close the shut-o valve (item 12 gure 2).

3. Open the draining valve (item 13 gure 2).

4. Undo the electrical heater’s outlet connection (marked with a red arrow) a little to let air in. The electrical heater contains ap-

prox. 15 litres of water. Make sure that all water has drained out.

5. Re-tighten the electrical heater outlet connection again once the heater is fully drained.

6. Close the draining valve.

With reservation for printing errors. We reserve the right to alter the technical specication and product range. Colour deviations may occur due

to printing techniques.
