Congratulations with the purchase of the Harmopool solar panels. This high-quality product is
completely developed and manufactured in Belgium by Zwembad BVBA.
Please read the instructions carefully before the installation and usage of the solar panels. The solar
panels are made to last for years with minimal maintenance required, provided that the
instructions regarding installation and usage have been followed.

Product description
The 33,33cm long collectors are made from ASA, which is more UV-resistant than ABS.
Furthermore, the solar panels consist of tiny tubes made from EPDM rubber. EPDM rubber
has several advantages compared to other materials:
○
○
○
○
Frost resistant
UV resistant
Protected against damages from chemicals (only use normal quantities)
Resistant against stretching
The collectors can be easily connected to one another with tie rips. The sealing O-ring
guarantees that the collectors are completely water proof.
The standard lengths are 2, 3, 4, 5 or 6 metres, but it is also possible to order custom made
solar heating. The width of a standard kit is fixed at 1 meter, which consists out of 3 rolls of 33
cm wide. The width can be extended indefinitely, by increments of 33 cm (one collector). Only
the end pieces remain to be assembled.

Since the entrance and exit are located diagonally from each other, the water will be heated
in the most efficient manner. It is recommended to place the exit at a higher level than the
entrance in order to push the bubbles out of the collector.
In order to obtain the best results, the solar panels have to be located towards the south
(45° France, 37° Belgium). When you place the collectors horizontally, 15% more solar panels
are required to be installed in order to receive the same efficiency.
Hereby the calculations for a swimming pool with a depth of 1,5 meters:
○ Swimming pool without cover: 125% of the swimming pool surface
○ Swimming pool with bubble cover: 75% of the swimming pool surface
○ Swimming pool with pool cover (Enclosure): 50% of the swimming pool surface
Per 10 cm depth extra, 10% more panels are needed. With the right amount of solar panels,
the temperature of the swimming pool can rise up to 6° per day.

Attention!
○ If the solar panels will be placed on a roof, it is recommended to use safety
equipment or to hire a professional.
○ The Harmopool solar panels have a warranty of 2 years covering manufacturing
defects. The warranty does not cover damages caused by poor installation or
external factors including, for example, weather conditions or chemicals. The
transport costs and labour hours are not covered by the warranty.
○ In order to receive the best results, the collectors have to be placement fully in
the sun. Furthermore, the water has to enter the panels at the bottom and exit
the panels at the top in order to push the air out of the tubes.
○ When the solar panels are placed higher than 6m, it is recommended to install an
aerator. When the pump stops, the aerator will automatically empty the
collectors. This prevents under pressure in the EPDM tubes when the pump is off.

Content in the box
Please ensure that the following materials are present:
○ 3 assembled EPDM-collectors (33cm wide).
○ 2 connectors to connect the solar panels to the filter (50mm - 38mm and 32mm/
entrance and exit of the water).
○ 2 sealing caps to seal the collectors.
○ Tie rips (8x) to connect the collectors.
○ Strap (8m) to attach the collectors to the roof (not included).

Assembly
1. Place the rolls next to each other, so they can be connected easily.
1. Put the sealing rings around the foreseen nick and connect the tubes. It will be easier
to connect the tubes after applying a small amount of soap. After connecting the tubes,
they have to be secured with the tie rips.
2. The water in and out connexion pieces are fit for flexible tubes with a diameter of 32,
38 and hard / flexible PVC tubing 50 mm. To connect a 50mm tube, cut off the
32/38mm connexions with a saw.

3. Place the sealing caps at the female ends and the connectors at the male ends. The
inlet and outlet are supposed to be faced diagonally.
4. Optional: Drill a hole in the sealing caps, so they can be easily emptied during the
winter. The hole can be closed with a 1 ¼ cap inch thread [ZALX3010] (The 1 ¼ cap is
not included).
5. Connect the pipe to both the entrance and exit of the solar panels (pipe not
included).
The solar panels can be connected to a filter with or without bypass. The kit does not include
a bypass and will operate whenever the filter starts. By placing a bypass (see below –
automatic or manual bypass), the solar panels will only be active when the temperature of
the solar heating is higher than the swimming pool and therefore be more effective.

Fastening the solar panels
With the nylon strap, the solar panels can be placed either horizontally or vertically.
Vertical placement
The strap can:
1. Fasten the solar panels
2. Fasten the heating system by weaving the strap horizontally through the
rubber. The strap is included with the solar panels. The solar panels can also be
attached directly to the roof with silicones (Versa bond,..).

Horizontal placement
It is also possible to assemble the straps underneath the roof tiles by connecting them to the
slating battens with screws. In this case, one attachment per collector is needed.

It is also possible to fasten the collectors with a concrete steel net.
Flat roof
The same methods can be used. The collectors can be connected to roof tiles, a concrete steel
net or silicones.
On the ground
It is recommended to place the solar panels in an area without plants or sharp objects. When
plants grow underneath the solar panels, it could damage them. Please refrain from walking
over the collectors to prevent damage.

Automatic or manual 3-way valve
The drawing below shows how a bypass can be made using a 3-way valve.
Using a Harmosol temperature controller, it is possible to regulate an automated 3-way valve,
which will send the water to the solar heating only when it is appropriate (temperature solar
heating higher than swimming pool temperature).
The Harmosol measures the difference between the water temperature and air temperature.
When the difference of the temperature exceeds the data given in the settings, the electric
valve will open/close. As a result, the water will run or stop running through the collectors
causing the water temperature to drop/increase.
Using a manual valve is also possible, but the manual valve will be less effective than the
automatic valve.
A detailed manual of the valves can be found on www.harmopool.eu.

Creating a separate circuit
A second pump can be installed in a separate circuit. A low power swimming pool pump
(e.g. 250 Watt) runs only when the sun shines.
The pump can be started/stopped by the Harmosol controller.
The Harmosol measures the difference between the water temperature and air temperature.
When the difference of the temperature exceeds the data given in the settings, the pump will
start/stop. As a result, the water will run or stop running through the collectors causing the
water temperature to drop/increase.
Using a manual start-stop is also possible, but the manual operation will be less effective than
the automatic valve.
A detailed manual of the valves can be found on www.harmopool.eu.

Maintenance
In order to prevent damage, please read the following tips:
○ During a chlorine-shock treatment, it is recommended to close the collectors in order
to prevent damage.
○ Before the winter, pure water has to run through the collectors. Afterwards, the
collectors have to be emptied.
○ Information about the maintenance of the accessories can be found in the manuals
on www.harmopool.eu.
