BE VERY CAUTIOUS WITH….
Roof’s stability
Before any installation, it is imperative to check the good state of the roof’s substructure and
its load-bearing capacity. Particular attention should be paid the timber substructure with
regard to the durability of screw connections.
The indications of this notice are only valid within the frame of the following restrictions:
- Roof inclination 20 ° - 45°
- Maximal building’s height 25 m.
- Wind speed inferior to 150 km/h
Ventilation
It is imperative to build a sufficient air circulation underneath the collectors. This ventilation
avoid the stagnation of water underneath the collector in case of heavy rains.
Contamination Prevention
During the installation phase, all ventilation holes and connections must be protected against
contamination and clogging.
avoids the stagnation of water underneath the collector in case of heavy rains.

for commissioning and also any
possible maintenance in the
future.
The pressure relief valve on the
pump station can be discharged
into the solar HTF container
situated next to the pump
station. If discharging into a
container then it is necessary
that there is a small amount of
fluid in the container to cool any
hot fluid which could potentially
discharge from the system.

Cutting
1. Split the pipes and cut the insulation using a sharp knife. Be careful not
to damage the wire.
2. Push the insulation back along the pipe to allow access for cutting the
pipes.
3. Cut the pipes in the valley of the corrugation using an adjustable pipe
cutter. Do not clamp the cutter on the pipe with great force or the pipe
will flatten.
4. Allow 1 additional valley on each cut of the pipe to produce the sealing
joint.
(An optional extra flanging tool is available which will create a perfect flange
finish on both DN 16 and DN 20 stainless steel pipework.
Final Connection
1. Insert the washer into the nut.
2. Screw nut onto the relative connection.
3. Tighten nut using a spanner.
The pipe should be supported every one meter using the correct brackets.
Flushing and filling the system - page 29
Technical changes may be made without notice
Flushing and filling the system
Before filling and pressurising, the system must be flushed, using a solar filling
machine, to remove any contaminants. It is recommended that the solar heat
transfer fluid is used as some parts of the system may not be able to be drained
down.
Connect the pipe from the bottom of the solar filling machine to the fill and drain
valve below the pressure relief valve on the pump station and connect the pipe
from the top of the machine to the fill and drain valve below the flow setter on the
pump station.
Open the fill and drain valves.
Ensure the flow setter is fully open.
Turn the right hand isolating valve (with integrated thermometer) on the pump
station a quarter turn clockwise to close the non-return valve.
Ensure the left hand isolating valve on the pump station is turned to the anticlockwise position to allow this non-return valve to be open.
Pour solar heat transfer fluid into the filling machine, ensure the isolation valve is
open on the bottom of the machine then switch it on to allow the fluid to circulate
through the system for 30 minutes to flush out the air and any possible debris.
To clear any air or debris from the flow setter and pump, turn the right hand
isolation valve anti-clockwise for 5-10 seconds then turn back clockwise.
To pressurise the system, close the fill and drain valve below the flow setter and
watch the pressure gauge on the pump station rise to 3 bar, close the fill and drain
valve below the pressure relief valve and then turn off the machine.
It is vital that the system is pressurised to 3 bar as this raises the temperature
boiling point of the heat transfer fluid.
Disconnect the machine and screw blanking caps on to the fill and drain valves on
the pump station. Next, make sure both isolating valves on the pump station are
turned to the anti-clockwise position.

With the pump running on full speed, the flow rate through the system can
be adjusted by turning the isolator on the top of the flow setter.
To ensure the primary solar system is free from air you must manually
switch on the circulation pump on the pump station via the solar differential
temperature controller. To see you have circulation through the system the
flow setter should give a reading of around 7 to 10 litres per minute.
The maximum flow of fluid through the system needs to be adjusted to give
optimum performance. This will depend on the number of collectors used
in the installation.
Commissioning the solar controller
The recommended settings for the solar controller are:
•
Switch on temperature difference 7°C
•
Switch off temperature difference 3°C
•
Minimum pump speed 40%
•
Store max temperature 65°C
•
For thermal stores or if the outlet temperature is controlled with a
suitable TMV then store max may be set to 85°C
For pipe runs which are greater than 10m from the store to the panel it is
recommended to increase the switch on temperature difference to accommodate for any possible heat loss.
To change any of the settings above please refer to the controller installation manual supplied with the controller.
Other functions on the controller are optional but are not necessary for
most systems. The descriptions of these functions are in the controller
manual.

System maintenance
The solar heat transfer fluid must be checked once every year to
investigate its antifreeze and pH value. These checks can be made using
a refractometer.
• Antifreezeconcentrationof40-45%.Ifthereadingisbelow30%then
the fluid will need to be replaced.
• pHValueof8.5-9.5.
• Refractiveindex:I.374
The collector/collectors should be visually inspected once a year for any
sign of leakage, damage or any sign of corrosion. Checks should also be
made on the mounting brackets/bolts for any corrosion or damage.
