Safety Considerations
SAFETY CONSIDERATIONS
• Sentinel Eliminator Nano® filter is a pressure vessel containing a hot fluid.
In the interests of reliable long term operation, it is strongly recommended
that the Sentinel Eliminator Nano filter is only installed by a qualified
plumber or heating engineer.
• Always ensure that the system is fully drained and the pipework completely
cooled before attempting installation. Check very carefully for any leaks
after fitting the filter and pressurising the system.
• The T piece collar must be hand tightened only – do not attempt to use a
tool as this could damage the seal.
• The filter bin is sealed permanently onto the main body of the unit – do
not attempt to remove the bin as this could lead to seal damage and
invalidate the warranty.
• Care should be taken when flushing a hot system.

General Description
GENERAL DESCRIPTION
The Sentinel Eliminator Nano central heating filter is designed for the effective
removal of all types of debris associated with wet central heating systems.
Sophisticated hydrocyclone technology is employed to remove both magnetic
(such as magnetite) and non-magnetic particles with equal effectiveness.
In the interests of long term reliability, the body of the filter is manufactured
from a high performance glass-reinforced engineering polymer, which has
been proven to withstand up to 13 bar static pressure.
The main filter body is permanently sealed. Removal of collected deposits
can be achieved by flushing at regular service intervals. Never attempt to
remove the bin as this could lead to a compromised seal and invalidate any
subsequent warranty claim.

System Design
SYSTEM DESIGN
The Sentinel Eliminator Nano filter is suitable for use on sealed and open
vented wet central heating systems with 22mm pipework only. Please do
not attempt to install on a 28mm system: the cyclones are not optimised for
the flow rates normally associated with these larger systems. Refer to the
Technical Specification for further details of the working flow rate envelope.
The filter is designed only for temperatures of up to 80°C and pressure no
greater than 3 bar. Exposure to temperature and/or pressure levels in excess of
these values could lead to premature failure and would invalidate the warranty.
The filter should be mounted on the boiler return pipe only.
Prior to installation, the system should cleaned with a suitable Sentinel cleaner,
such as Sentinel X800 Fast Acting Cleaner. The unit is fully compatible with
Sentinel X100 Inhibitor, Sentinel X500 Inhibited Antifreeze and Sentinel X900
Filter Aid.

Mounting Considerations
MOUNTING CONSIDERATIONS
Before fitting the filter, ensure that adequate clearance is available, including
the vertical space required to drain the filter during servicing.
The filter can be fitted to either horizontal or vertical pipe work by rotating the
T piece – see Figure 2 for details.
Regardless of pipe work orientation, the filter must be mounted vertically. Also
please ensure that the flow direction of the T piece is observed.

INSTALLATION PROCEDURE
Note on isolation valves
The filter is supplied with a separate
¼ turn ball valve for isolation
purposes. This can be fitted (if
desired) during installation.
Boilers typically have an integral
valve on the return leg, so in
instances where full isolation is
desired, the separate ball valve can
be fitted on the opposing side of the
filter (as per Figure 3). As a result,
full isolation can be achieved within
a minimal size envelope and with the
fewest number of components.
Alternatively, the filter can be fitted
without the supplied valve but full
isolation will not be possible, should
the filter ever subsequently need to
be removed.

Installation Procedure
INSTALLATION PROCEDURE
(CONTINUED)
Step 1:
Select a suitable location for the filter
and remove a section of pipe 54mm
in length. The Sentinel Eliminator
Nano should be installed on the
return to the boiler.
Step 2:
Unscrew the plastic collar piece,
shown in Figure 1 (p. 6), and remove
the brass T piece assembly from the
main filter body. Retain the loose
gasket for refitting later.
Step 3:
Attach the brass T piece to the
pipework using the integral
compression fittings – see Figure
4 for details of the T piece fitting
method. Ensure that the flow
direction is correctly observed. The
nuts and olives can be found in a
separate bag.
Step 4:
Reposition the T piece gasket and
secure the filter to the T piece,
ensuring that the retaining collar is
hand tight. Please do not, in any
circumstances, use a tool to tighten
the collar as this could result in
damage to the seal and compromise
long term reliability. Any such misuse
will invalidate the warranty.
Secure upper and lower compression fittings
in turn, using a tool (e.g. pump pliers) to hold
the T piece steady. Note that the position of
the pliers must be flipped in order to provide
adequate spanner clearance.

Installation Procedure
Step 5:
Refill and pressurise the system
and use the bleed valve to remove
any trapped air. Check carefully for
any leaks and ensure that the drain
valve is fully closed with handle in the
horizontal position.
Ensure that the system is protected
against corrosion and scale by
dosing with Sentinel X100 Inhibitor
or Sentinel X500 Inhibited Antifreeze
(whichever is appropriate for the
property in question). Correct levels
of inhibitor can be checked with a
Sentinel X100 Quick Test Kit.

Servicing
SERVICING
The Sentinel Eliminator Nano filter
requires minimal maintenance other
than intermittent flushing to remove
any collected debris. This can be
done anytime, or at least during the
annual boiler service. Care should
be taken when flushing a hot
system.
Step 1:
Place suitable shallow container
underneath the filter.
Step 2:
Remove the small nut retaining the
drain valve handle. See Figure 5.
Step 3:
Flip the handle over and re-engage
with the valve shaft (Figure 6). Open
valve to release the collected debris.
Step 4:
Close the valve and replace handle,
together with small retaining nut.
Step 5:
If necessary, re-pressurise the
system, topping up with Sentinel
X100 Inhibitor (as required). Check
carefully for any leaks.

Dosing
DOSING
In instances where full isolation of the filter is achievable (as per Figure 3) it is
possible to use the filter as a chemical dosing point for Sentinel’s Rapid Dose
products following the sequence below:
Step 1:
Assemble dosing adaptor in line with the Rapid-Dose instructions (for use with
bleed pin).
Step 2:
Ensure boiler is turned off and the system is cooled with pressure below 2.3 bar.
Step 3:
Close the isolation valves and remove bleed pin (slowly), catching any escaping water.
Step 4:
Cut down bleed pin adaptor to correct size for the valve. Ensure the rubber
bullet is next to the can actuator.
Step 5:
Screw the dosing adaptor into the bleed valve.
Step 6:
Open the isolation valves, expect water to enter the tube – the rubber bullet will
seal the tube.
Step 7:
Screw the Rapid-Dose can onto the can actuator, dosing will commence (you
will see the rubber bullet shooting forwards).
Step 8:
When dosing has finished, close the isolation valves.
Step 9:
Slowly remove the dosing adaptor and reinsert the bleed pin; securely tighten.
Step 10:
Open isolation valves.
