Install the
Fernox TF1
in an easily accessible
position for servicing ie: the vertical return to the
boiler. Allow adequate clearance above the unit to
enable the removal of the magnet assembly and
draining. The drain valve is factory fitted and cannot
be removed or adjusted.
Installation options
The Fernox TF1 comes ready to install into vertical
pipe work with the system water flowing upward.
1. Switch off the boiler and drain the system.
2. Measure and remove the section of pipe work
where the
Fernox TF1
will be installed.
For 22 mm pipe work, remove a 210 mm section
(for 28 mm pipe work, remove a 220 mm section).
3. Connect the valve fittings supplied to the
pipe work.
4. Connect the
Fernox TF1
to the valve fittings
ensuring that the rubber valve washers are
correctly positioned. The unit should be installed
so that the direction of flow within the heating
circuit follows the directional arrows found on
the inlet/outlet port.
5. Tighten all connections. Special care should be
taken not to over-tighten the valve flange nuts that
connect to the
Fernox TF1
inlet/outlet port.
Installation in other orientations
1. Loosen the lid collar to allow the inlet/outlet port
to be unscrewed from the main body of the unit.
2. Replace the black sealing ‘O’ ring fitted in the inlet/
outlet port with the appropriate ‘O’ ring provided
in the Fernox TF1 Kit and add the relevant spacer
between the main body and the inlet/outlet port
before re-tightening.
For horizontal pipe work flowing from left to right,
add the yellow ‘O’ ring and black spacer.
For horizontal pipe work flowing from right to left,
add the blue ‘O’ ring and blue spacer.
For vertical pipe work flowing downwards,
add the red ‘O’ ring and red spacer.
3. Re-tighten the lid collar using the Fernox lid
spanner. Note: The lip of the lid collar must
be in-line with the block on the inlet/outlet port.
The Fernox lid spanner is required to tighten the
lid collar fully.
Fernox Total Filter TF1 instructions
Commissioning
• Open both inlet and outlet valves to fill the unit.
Vent any entrapped air and check for leaks before
switching on the boiler.
• Complete the
Fernox TF1
maintenance and service
label and apply to the boiler.
• For continual protection
Fernox Protector
levels
should be checked annually.
• When adding any component to a heating system,
it is the installers responsibility to ensure the
system continues to comply with BS7671:2008
guidelines/requirements for electrical installations.
Cleaning the unit
Option one – fast clean
Cleaning of the unit does not require disassembly.
1. Switch off the boiler and close both inlet and outlet
valves on the
Fernox TF1
.
2. Remove the magnet from the centre of the lid
to allow trapped magnetite to fall into the base of
the vortex. Wait for 30 seconds for the magnetite
to settle.
3. Remove the drain valve cap and key from the drain
valve. Either connect a hose to the drain point on
the bottom of the unit using a standard hose tail
connector or place a suitable container beneath
the unit to collect the discharge.
4. Open the outlet valve.
5. Carefully open the drain valve using the drain valve
cap and key to flush contaminants from the unit.
6. Close the drain valve and refit the cover. Replace
the magnet and open the inlet valve.
Option two – manual clean
Cleaning of the unit can be undertaken in-situ.
1. Switch off the boiler and close both inlet and
outlet valves on the
Fernox TF1
.
2. Release system pressure via the vent point.
Unscrew the lid collar and remove the lid and
magnet assembly together.
3. Remove the magnet and wipe or rinse off residual
magnetite from the sleeve. Note: This method
only cleans the material trapped by the magnet
assembly. If required, the remaining contaminants
can be discharged via the drain point. Good
practice is to replace the lid seal after cleaning via
this method. Replacement seal kits are available
through all good plumbing merchants.
4. Place the magnet back in the sleeve and
re-assemble the
Fernox TF1
.
The lip of the lid collar must be in-line with the
block on the inlet/outlet before switching the
boiler back on. The Fernox lid spanner will be
required to tighten the lid collar fully.
5. Open both inlet and outlet valves and vent any
entrapped air.
After cleaning always check system pressure and
adjust as necessary before operating the boiler.
Chemical dosing point
The
Fernox TF1
can be used to dose any
Fernox 500 ml
,
Express
and
Superconcentrate
water treatment products into the system.
1. Switch off the boiler and close both inlet and
outlet valves.
2. Remove the drain valve cap and key from the drain
valve. Either connect a hose to the drain point on
the bottom of the unit using a standard hose tail
connector or place a suitable container beneath
the unit to collect the discharge.
3. After opening the bleed valve to vent the chamber,
open the drain valve. Close the drain valve and
replace the cap once emptied.
4. Dose the chemical via the vent point either using
the screw thread adaptor supplied with all Express
or Superconcentrate products, or remove the
bleed valve completely and dose 500 ml liquid
via a funnel.
5. Replace vent pin and bleed valve, if removed.
6. Open both inlet and outlet valves.
7. Vent any entrapped air and check system pressure
before switching on the boiler.
