For the product to work as intended, the system must be
fully bled.
It is extremely important that a basic bleeding of the product is carried out
systematically and carefully.
Bleeding devices must be fi tted to the system’s natural high points. A
basic bleeding of the hot water tank can be carried out upon installation by
releasing the safety valve, which must be fi tted to the top of the product.
The water must be circulated during bleeding of the various subsystems:
the radiator systems, heat pump system and hot water charging system
(to run the pumps, 3-way valve etc. manually, go into the menu Installer/
Service/Function test). Also move the 3-way valve during the bleeding
process. A careful basic bleeding must be carried out before the system is
put into operation and the heat pump is started.
Tip:
Once basic bleeding is complete: increase the water pressure in the
system temporarily to approx. 2 bar.
• Automatic bleeding valves are included in the package and supplied
as standard for this product. They must be fi tted to the top of the
product as shown in the picture.
• Important! Bleed any air remaining in the radiators (elements) and
other parts of the system after it has been in operation for a short
time.
Small microbubbles gradually collect in the system’s ‘pockets’, and it
can take quite a long time before all the air is removed from the system.
When the pressure is temporarily increased, any remaining air pockets are
compressed and carried along more easily with the fl ow of water and can
be released into the ventilation devices.
Tip:
After the air is bled, there may be a drop in system pressure. Having the
system pressure too low increases the risk of noise in the system and of
air being ‘sucked’ in on the suction side of the pump. Keep an eye on the
system pressure. Bear in mind that the system pressure will vary during
the year due to changes in temperature in the heating circuit, which is
completely normal.
If ‘gushing’ sounds can be heard from the product, this is a sign of
remaining air.
A loss of heating functionality can also be a sign of remaining air.
The automatic bleeder
is equipped with shut
off screws.
