COMBIMAG POWER FLUSHING FILTER
The CombiMag filter increases power flushing
efficiency by removing circulating black iron
oxide contamination from the system water. The
filter is simply installed in line between the
heating system and the power flushing pump.
The CombiMag controls the flow of water to give
a high residence time within the cylinder, to
ensure that the maximum amount of black iron
oxide is extracted from the water by the
powerful magnet.
The design is such that even at maximum
capacity, there is always a clear passage for the
circulating water.
The transparent cylinder enables progress of a
power flush to be visually monitored, and
enables the engineer to quickly check if the
magnet requires cleaning.
The built in bypass enables the magnet to be
cleaned without the need to temporarily stop the
power flushing process.
Benefits
Reduces dumping time by removing solids from
the water whilst circulating.
Collects circulating deposits that could lead to
blockages in restricted areas, and prevents
them re-entering the system.
Protects the boiler during power flush.
By-pass enables the magnet to be inspected
without the need to interrupt the power flush.
Reduces environmental contamination by
collecting the iron oxide and reducing the
amount of water consumed.
Provides an impressive
visual aid to both the
householder and the
engineer by showing the
quantity of sludge removed
from the system, and
confirming the need for a power flush.
Demonstrates why a permanently installed
magnetic filter may be beneficial.
Wipe clean magnetic
surface to minimise
cleaning time and
effort.

COMBIMAG POWER FLUSHING FILTER (continued)
Connecting the Filter
The power flushing pump can circulate the system
water in either direction by operation of the flow
reversing lever. However we suggest that the initial
set-up is such that the CombiMag filter is installed
before the boiler to offer the boiler a higher level of
protection in the early stages of the power flush.
1. Place the CombiMag power flushing filter
adjacent to the power flushing pump on a suitable
drip tray.
2. Select the required direction of flow and position
the pump flow reverser lever in that direction.
3. Install the filter on the flow from the flushing pump
using the short (1½ metre) hose supplied.
Connect the flow to the bottom connection on the
filter.
4. Using the power flushing pump standard flow and
return hoses connect both the pump and the top
connection on the CombiMag to the heating
system.
5. Both CombiMag three- port valves should be in
the CIRCULATE position.
Operating Instructions
1. Turn on the power flushing pump and
immediately check all connections, and the top of
the CombiMag cylinder for leaks.
2. After initial circulation for approximately ten
minutes, turn both three-port valves 180° into the
BYPASS position.
3. Remove the securing ring from the top of the
cylinder and, gripping the handle firmly, carefully
lift out the magnet.
Note: the magnet is very powerful and is
strongly attracted to steel surfaces. Take care
not to trap fingers and avoid contact with
sensitive equipment.
4. Inspect the magnet for collected deposits and, if
necessary, clean as follows:
5. Grip the cylinder lid and handle with one hand.
Whilst wearing disposable gloves, grip and slide
the magnetite sludge down and off the magnet.
Note: It is advisable to only remove a proportion
of the deposits with each stroke, starting at the
lower end of the magnet, rather than all at the
same time. Clean the end of the magnet.
6. Collect the sludge in a suitable container for later
disposal.
7. Re-assemble the CombiMag ensuring that the
magnet locates within the circular recess at the
base of the cylinder, and turn both three-port
valves back into the CIRCULATE position.
8. Repeat the inspection and cleaning procedure as
required during the flushing process.
Cleaning the Magnet
It is not necessary to remove all deposits during the
intermediate cleans whilst power flushing. However,
to ensure a long life the magnet should be
thoroughly cleaned and dried at the end of each job.
Caution
The CombiMag contains a very strong magnet
and generates a very powerful magnetic field.
When removed from the cylinder, keep away
from electronic equipment, watches, mobile
phones, credit cards etc.
