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.

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.
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.

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.
