05 Installing the Filter Head and Bracket [14]
To install the filter system, choose a location that enables
simple connection to the water mains and tap. The
distance between the filter cartridge and the floor should
be a minimum of 65 mm to allow adequate space for
installing the filter cartridge. The filter system must be
securely fitted to a suitably robust surface using the filter
bracket supplied. Remove the bracket from the filter head
and use as a template to mark the appropriate location.
Drill two pilot holes and fasten the bracket using two
suitable screws or bolts (not supplied). Correctly fitting the
mounting bracket will support the weight of the filter and
help prevent strain on the attached pipes and fittings.
06 Connecting the filtered water supply
Attach the 7/16 x 1/4 Push - fit adaptor [15] to the
threaded tap tube being careful not to over tighten.
Using a sharp hobby knife or similar cut the blue flexible
hose [12] to a suitable length for it to reach between the
Push - fit adaptor [15] and filter head [14] remember to
allow sufficient length so that it can be routed with out
kinks and be kept clear of any sharp edges.
With the tube cut squarely ensure the end is clean and
smooth before (A) pushing firmly and fully into the
adaptor fitted to the tap, (B) pull back slightly to effect a
water tight seal.
Carefully fit the 3/8 x 1/4 ‘push - fit adaptor’ [16] to outlet
side of the filter head [14] taking care not to over tighten,
and then slide the filter head into the bracket taking care
to observe the direction of flow indicated by the arrow
Now take the other end of the blue flexible tube [12] and
push firmly and fully (D) into the adaptor [16], pull back
slightly to effect a seal (E)

08: Installing the Cartridge
Remove the cellophane shrink-wrap and hygiene cap
from cartridge [13]. Before installing the filter cartridge,
mark the installation date and the replacement date (no
later than 6 months) in the space provided on the filter’s
label. Hold cartridge near the bottom when installing or
changing the cartridge. Push the cartridge into the filter
head [14] and the same time rotate anticlockwise when
viewed from above. Installation can be simplified by
turning the filter head in the filter bracket by 90° where
space permits.

Mains water
09: Bleeding the system
Open the filter water tap [1] fully to allow for continuous
flow, then slowly turn on the water supply allowing water
to enter the filter slowly and displace trapped air and
loose particles.
Allow water to flow through the system for around 5
minutes or until water runs clear and bubble free
(Minimum 5 litres). Repeat flushing process when ever the
filter is left unused for a prolonged period of time. Always
flush drinking water filter system for 10 seconds
10: Setting the bypass
Your BWT filter head [14] is fitted with a 4 position bypass
valve that can be used to allow filtered water to be mixed
with incoming water from the mains for specialist
applications. For domestic drinking water DSSOLFDWLRQVWKH
11: Replacing the filter cartridge
Turn off the water supply at the water supply valve before
starting work. Unscrew the filter cartridge [13] out of the
filter head [14] in a clockwise motion dismantling can be
simplified by turning the filter head in the filter bracket by
up to 90° where space permits
