and air separator
o This makes it possible to maintain the sludge and
air separator easily without draining the heating
system
• Mount the sludge and air separator at easily acces-
sible points in the system
7.2 Installation notes for the quick bleeder
• To prevent malfunctions of the quick bleeder by dirt
particles that enter from the outside, the red valve
cap should remain on the quick bleeder
• Leave the red valve cap open to just one rotation to
the stop so that the air can bleed
o Thereby the quick bleeder will definitely not drip;
dirt and floating particles cannot get into the blee-
ding mechanism
7.3 Installation into pipeline
1. Unpack the device and inspect for completeness
and any possible transport damages
2. Remove the insulation by loosening the securing
clamps
1. Thoroughly flush pipework
2. Install rotatable connector piece
o Note flow direction
o Install without tension or bending stresses
3. Before starting up, make sure that the ball valve is
closed
7.4 Installing the phosphate cartridge (available
as an accessory)
1. Screw out the blind plug (SW27)
2. Screw the phosphate cartridge into the sludge and
air separator in clockwise direction
o The phosphate cartridge consists of a brass
coupler, a magnet, a filter basket and the phos-
phate filling
3. Screw the blind plug in with not too much force
8. Commissioning
1. Increase the water pressure slowly to the operating
pressure of the heater (max. 10 bar)
2. Slowly open the stop valve ahead of the sludge and
air separator
3. Visually check the sludge and air separator if it leaks
4. Release the pressure in the sludge and air sepa-
rator by opening the lower ball valve
5. Close the lower ball valve again
6. Slowly open the stop valve following the sludge and
air separator
7. Mount the insulation
9. Inspection
The following inspections need to be made regularly by
the operator to ensure the proper functioning of the
device.
• Leak checks, visual inspections
• Check for soiling every month
• Check the quick bleeder every year
10. Maintenance
10.1 Rinse out sludge and air separator
1. Place a suitable, heat-resistant container under-
neath
2. Slowly open the lower ball valve
3. Close the lower ball valve again after about 4-6 litres
have drained
4. Refill heater system if necessary
Before starting up, make sure that the ball
valve of the device is closed.
Before installing the sludge and air separator,
the pipelines need to be rinsed.
In case aluminium materials are used in the
heater system, the phosphate cartridge may
not be installed.
If the phosphate cartridge should not be
installed until after the startup, then proceed as
described in chapter 10.3 Replace phosphate
cartridge.
Before starting up, make sure that the ball valve
is closed.
The control intervals are the minimum recom-
mendation and ought to be appropriately shor-
tened by the operator if the consumer system is
sensitive.
• Maintenance, service and repair work may
be carried out only by authorised techni-
cians.
Depending on the degree of soiling of the
heater water, the sludge and air separator
needs to be rinsed out regularly.
Danger of scalding from hot heater water!
