SOLAR HEATING
Ref. 90230
Solar heater for swimming pools
Method of use

Operation

A filtering unit for the pool that allows heating the water with a solar heater.
The minimum power of the pump should be 2,000 l/h. The solar heater should be situated next to the swimming pool towards the south with a 30º inclination.
The foldable feet of the heater allow placing the heater with the correct inclination. Solar energy accumulates below the transparent lid and later is distributed toward the water supply tube. The heating that is noted at the outlet from the solar heaters depends on the speed of the water flow.

Materials

Sun is needed to start the solar heater. This may remain connected although there is no sunlight as it only causes a very slight loss of power when it is connected. Current filtering units can be used with the 32 and 38 mm hosepipe connectors. Additionally the solar heater can also be installed on the roof of your garden house. All that is necessary is to ensure that the filtering equipment will have sufficient power at that height or that the filter is well equipped to resist higher pressures (1m height represents 0.1 bar of pressure). If additional sections of tubing are used or the position is higher, the power of the pump will be reduced. Always face the heater to the south and make sure it receives sunshine all day. The foldable feet will facilitate obtaining the correct 30º inclination. We recommend using the same angle for roof-top installations.

There is a white cover inside the box that is for use on extremely hot days to avoid the water overheating.

Easy assembly

The only tool you need is a screwdriver to fix the hosepipe to the solar heater. There are long hosepipes included for easy installation. If you need to connect more than one solar heater, the short piece of hosepipe can be used. We recommend not assembling more than 4 solar heaters in series. If more are needed, for a very large pool, we recommend assembling 2 or 3 series in parallel. We recommend using one solar installation for pools up to 7.5 – 10 m3. (This is merely a suggested size as the result depends on exposition time and solar power). Easy assembly
Open the box and check that all the elements are included according to the following list:

Solar heater with detachable transparent lid
Unfold the feet at the bottom part to obtain a 30º inclination
Long tube (1.2 m) for connecting the solar heater to the pool
Short tube for coupling 2 heaters at the same time
2 adaptors for 32/38 mm connection
Bag with metallic clamps
Rubber reduction pies 38/32 mm
White cover

32 mm hosepipe adaptor: Connect this directly to the adaptor and fix it with the me- tallic clamps.
38 mm hosepipe adaptor: First connect the 32/38 mm rubber reduction piece to the adaptor. Later connect the 38 mm hosepipe to the adaptor and fix it with the metallic clampRemove the dust and filth from the transparent cover
− Start the filtering equipment with the water circuit open.
− Check the water-tightness of the heater and of the hosepipes
− Now, you can start saving money thanks to the solar heater by heating your pool free of charge

Installation of several systems

Identical assembly to that above except we use the short hoses to couple the heaters with each other.

Protection for winter
To avoid icing problems, completely purge the system during the winter Store the heater in a dry spot and free from icing.
