This installation and useer´s manual contains important product information and safety recommendations.
Read this manual carefully before installing, operating or starting any work, observing the safety and protection
instructions, always following national and regional rules and regulations.
Observation: This manual is applied in systems with the following solar panels: TK 20, TK30, TK40 and TK50.

Traditionally, heat pump manufacturers for pool
water conditioning recomend to use the same
water pump for ltering and water heating.
*Sand lter installed in series with the heat or
independent pump with its own water pump.
(See item 1.2 and 1.4).
This practice is quite convenient because the
hydraulic ltering circuit provided would be
theoretically used and only the heat pump would be
installed in the sand lter output.
The greatest inconvenience of this assembly
system would be the fact that heat pumps need a
specic ow for their own operation and better
performance.

Filtering depends on the water volume
Heating depends on water temperature
This ow is often not attended by the low capacity of the
lter water pump, which is aggravated by the sum of the
lter load losses added to the heat pump, apart
from the elevation of the losses, if the pipe is originally sized
just for the ltering system.
Another disadvantage would be the fact that ltering and
heating are different events and in case there is a ltering
programming, this same programming will be imposed on the
heat pump, limiting the periods of its operation or
consequently, the heating of the pool. And if the
programming is scheduled for heating, then ltering periods
may be longer than necessary.
In cases where the hydraulic circuit and the ltering system
(including its water pump) is subdimensed it is better to
separate into two different hydraulic circuits. One for the
ltering with its own command to drive the water pump (B3)
and another one only for the heat pump with its own drive
command and its water pump (B1).
For the solar heating system, the hydraulic circuit with the
water pump (B2) must be exclusive, since its differential
temperature controller will drive the system only with the
incidence of solar rays.
Observation: Any water circulation through the solar panel at
night or period without sun will cool the water, to some
degree depending on the ambience temperature, if it´s
windy and also it may dipend on the temperature of the
pool and the circulation period.

It is important to know that solar thermal heating for
swimming pools is different from solar thermal heating for
bathroom. In the pool system there should always be
considered the kind of swimming pools and the use to
which they are intended:
Residential pools, clubs and gym
Ideal temperature: between 28°C and 32°C.
3. Dimensioning - Number of solar panel
Training and competition swimming pools: 28C
Physiotherapeutic treatment pools: between 33C and 35C

Solar panels quantity = Pool area x Regional coecient
Solar panels area instaled
Verify what the area of the swimming pool surface is.
Example 8 x 4 = 32m²
4. Dimensioning - Water pump and pipes
In a 32 m² system of solar panels, multiplied by
200 = 6,400 liters per hour, this is the water pump ow
to be used, verifying in the manufacturer table the ratio
of the height and distance of the pump in relation to the
solar panels.

Attention: Check the total system operation weight, and verify that the place supports this
weight.
The wrong dimensioning of pipes will considerably harm product performance.
Never exceed the maximum quantity of solar panels in a battery, this will cause
considerable losses in their performance.

Bearing in mind how many m² the project is, you can
calculate the right power of a water pump to be installed
and the pipes caliber to be used in the hydraulic circuit.
Always consider the quantity of m² of each battery and
multiply by 200 liters.
With this information and using the ow table below
you can choose the necessary caliber to build the
hydraulic system.

Inclinations from 10 ° to 30 ° must be oriented for the
geographical north.
•The orientation of the solar panels should be in the direction
of the roof inclination.
•
On at surfaces without inclination, panels may be oriented
in any direction.
•
TeKSOL solar panels cannot be installed under the upper level of pool water.
Avoid installing the solar panels batteries higer than 12 meters from the pool water level.
Avoid installing batteries in irregular places since this can compromise the solar panels
conection generating drip and losses.

6.1 Necessary pieces to install the solar panels.

7. Cleaning and conservation
First, apply Vaseline over the O'ring seals
in order to reduce friction at the time of
tting between the male/female parts,
avoiding damage to the O'ring seals.
Insert the male nozzles into the female
nozzles of the collectors until the holes
where the locks will be inserted to face
each other.
Helping with pliers, insert the
security locks in the corresponding
holes and make sure that they have
reached the end, making them lock
and preventing them from coming out
over time.
To nish the batteries, apply PVC
glue on the opposite nozzles as well
as on the inlets and outlets of each
battery and place the PVC plugs cap
to seal the end of the water course.

7.1 Verication
7.2 User instruction
Only if those solar panels are dirty to the point of
affecting their efciency, clean them with water and
neutral soap.
•
Attention:
Attention: Do not step, pull or scrape the
solar panels
The maintenance and/or cleaning
should be carried out only by
qualied and trained professionals
to avoid accidents.
The user is responsible for the security and proper
functioning of the system.
•
To carry out the installation, we recommend hiring
specialized and authorized companies.
•
Replace defective components immediately.
•
Use only original parts.
•
The installer must inform the user about the operating
mode of the system
•
Any modication made to the project must be
previously authorized by the company that carried out
the project or by the store that sold it.
•
Verify and retighten connections to prevent
losses and droplets. Period: 30 days after installation
and subsequently every six months.
•
Check the solar panels clamps and anchors on the
roof or surface where the batteries were installed.
•
In colder regions, when there is a possibility of
temperatures below 10°C and is not installed an
antifreeze system, leave the system off and empty
to avoid the freezing of water inside the tubes, which
may damage the system.
•
Our solar panels were developed to have the minimum
possible maintenance, in order to guarantee a good
functioning, some cares are necessary:

8. Freeze Protection
8.2 – CDT controller
(Differential temperature controller)
The CDT's has an internal protection system that
activates the pump if the water in the solar panel reaches
very low temperatures, such as 5°C, it is important that
this temperature is never very close to the freezing limit,
since the water can have different temperatures at
different points on the panel, and the sensor is always
located at the highest point of the project.
Attention: In regions below the tropics it is very common that the ambience temperature may drop below 0°C.
When it happens, water freezes, we see frost on the grass and roofs.
This is extremely detrimental to solar panels, the water stored inside freezes. When it happens,
the water expands and generates cracks, mainly in the riser tubes.
8.1 – Purge Valve (Air Eliminator)
The purge valve is an essential part of the installation,
it removes the air from the pipes, and allows the water
to drain into the pool when the water pump stops,
leaving the solar panels completely empty, preventing
water stored inside the collector overnight.
Also, if the system pipes are completely empty, when
the water pump is turned on, after the water rises to the
solar panels, when it begins to go down by the return
pipe, the water speed of descent may be higher than
the ascent speed, generating negative pressure,
causing damages if the pipes are warm.
8.3.1 - The Bypass guarantees that when the pump
stops, water from the pipe returns to the pool, leaving
the so l a r p a n e l s and th e i n s t a l l a t i o n pipes
completely empty when the system is turned off.
The Bypass register must allow passing from 3 to 10% of
the ow. For safety, after regulating, remove the handle
to avoid the system deregulation.
8.3 – Bypass and perforated retention valve
8.3.2 - The perforated check valve ensures that even
with a bypass failure, the water slowly returns to the
pool.
If this valve is not placed, the water may quickly return
through the water pump in the opposite direction,
loosening the pump rotor and generating a kind of
backwash in the lter, causing dirt to come out through
the nozzles in the pool.
This valve must be installed at the installation highest
point.
