Installation instructions
Pump fittings assembly 10E / 20E
- Only specifically trained and qualified persons are permitted to work on
electrical components. Pass connecting cable of circulation pump 1 through
insulation and connect as described in the installation instructions for the solar
control units.
- Thoroughly flush the system before filling.
Flow rate control
- For this purpose, open the ball valve in the return line.
- Use a screwdriver to turn the gravity brake in the return line to
the vertical position
- Use a screwdriver to turn the adjusting screw on the
flow regulator to the vertical position
- Flush the system until clear water emerges, free of
residue.
- Completely drain the system at the lowest point.
Do not fill the system with the sun shining strongly on the solar collectors or cover the
collectors.
Only use undiluted ANRO process medium to fill the system. Never add water or
other process media, otherwise this may cause flocculation, resulting in complete
failure of the system.
- Fill the system with ANRO process medium until the fluid emerges at the air
vent bowl.
- Close the air vent valve at the air vent bowl and continue filling the system up to
a pressure of approx. 3 bar (medium temperature 20 °C).
- Turn the gravity brake back to its initial position
- Check the system for leaks.
- Press on front insulating shell 3 and slide onto flow/return branch.
- Start the solar control unit
(see control unit installation and operating instructions).
- Set the circulation pump in the solar heating system to manual operation
(see control unit installation and operating instructions).
- Turn the adjusting screw on the flow regulator to the vertical position
(max. flow).
- Set the circulation pump to a speed above the recommended flow rate at the
speed switch (rough setting).
- It may be necessary to bleed the system several times and set it to a pressure
of 3 bar.
Recommended flow rate:
a) 1 to 8 solar collectors:
b) 9 to 10 solar collectors:
e.g. 3 solar collectors x 1.5 l/min = 4.5 l/min
- The recommended flow rate can be finely adjusted at the adjusting screw on
the flow regulator.
Remove the cover from the solar collectors.
Circulation of the process medium can be checked in the observation window in the
flow regulator.
