Where a mixer tap is installed, there is often an isolation
tap provided where the water supply exits the wall for both
the HOT and COLD water supplies. Locate the COLD water
tap, which is normally on the right hand side looking into the
cupboard. Turn this tap off (normally by turning clockwise).
Test that the water is off by turning on the mixer tap and
checking for water flow.
2 (b)
If the water is off, disconnect the flexible connection
pipe from the COLD water isolation tap. This flexible
connection pipe supplies water to the mixer tap.
2 (c)
Remove the two compression nuts and olives from the
Brass Tee (28) provided. Using thread tape, screw the tee to
the isolation tap using the centre outlet with the internal
thread. Endeavour to have the tee tight and in a suitable
direction so that the flexible connection to the mixer tap can
be reconnected to one of the two remaining outlets on the tee.
Reconnect the flexible connection from the mixer tap to the
tee, thread tape is not required. Tighten sufficiently, to avoid
leaking.
2 (d)
Take the Multi Function Control Valve (17) and with
the Hex Key provided, unscrew the inlet nut by holding the
Multi Function Control Valve (17) in one hand and placing
the Hex Key in the key provision provided in the inlet nut
adaptor and unscrew by turning anti-clockwise.
Care must be taken, not to allow the Hex Key to enter the
inlet nut adaptor more than is necessary, as there is a Particle
Screen housed under this inlet nut adaptor. This important
component of the valve will be re-used and must not be
damaged in this process.
2(e)
Screw the Multi Function Control Valve (17) to the other
side of the tee piece. Ensure that the Particle Screen is fitted
to the entry point of the Multi Function Control Valve (17).
Although thread tape is not required when screwing the Multi
Function Control Valve to the tee, as the “O’ ring on the
Particle Screen will seal this joint, thread tape can be used if
this method is preferred.
2(f)
Using thread tape, wrap the thread of the Purifier
Isolation Tap (16). There are two outlet ports available on the
Multi Function Control Valve (17), one in the end opposite the
inlet connection and one on the side, select the port you want
to use and screw the Purifier Isolation Tap (16) into this port
until it is tight. Screw the Stopper [17(1)] provided with the
Multi Function Control Valve (17) into the unused port. This
Stopper has a tapered thread and therefore does not require
the use of thread tape, however, thread tape can be used if this
method is preferred. Tighten both the Isolation Tap (16) and
Stopper [17(1)] sufficiently, to avoid leaking.
Caution! Screw the Multi Function Control Valve (17)
to the tee by hand. DO NOT USE TOOLS,
OVERTIGHTENING MAY DAMAGE AND AFFECT
THE OPERATION OF THE VALVE.
Some installations have ½” copper pipe exiting the wall and
proceeding directly to the COLD water tap on the sink with
no plumbing fittings and therefore, do not allow
disconnection and the use of existing fittings to provide a
water supply for the Water Purification System.
In this situation, it will be necessary to cut the copper pipe and
insert the Brass Tee provided.
3(a)
Locate the COLD water pipe, which is normally the pipe
on the right hand side looking into the cupboard. Turn the
water supply off, if there is not an isolation tap handy, turn off
at the meter or the point of entry to the building. Turn on the
tap at the sink to be sure the water is turned off, before
proceeding with the installation.
3(b)
Find a suitable, straight section of pipe where the Brass
Tee (28) provided can be inserted. Calculate the length of the
pipe to be removed, allowing for the length of pipe to be
inserted in each side of the tee. Make two cuts using a pipe
cutter or a hacksaw and remove a sufficient length of copper
pipe to insert the tee. Ensure not to damage the pipe in this
area and that there are no rough edges on the two pipe ends
where the section has been removed. If necessary use a file or
emery paper to dress any damage to the pipe.
3(c)
Take the Brass Tee (28) provided and remove the two
compression nuts and olives, place a compression nut onto
each pipe end and then place an olive on each pipe. Ensuring
the olive is the correct way around to seal.
Place the body of the tee piece onto the pipe and slide the
olive and nut up to each side of the tee, screw the compression
nuts onto the body of the tee piece. Point the tee in the
required direction and tighten both compression nuts to
prevent leaking.
3(d)
Using the ½” Nipple (29) provided, wrap one side of the
nipple with thread tape and screw this into the internal
threaded outlet of the tee piece.
3(e)
Take the Multi Function Control Valve (17) and with the
Hex Key provided, unscrew the inlet nut by holding the Multi
Function Control Valve (17) in one hand and placing the Hex
Key in the key provision provided in the inlet nut adaptor and
unscrew by turning anti-clockwise.
Care must be taken, not to allow the Hex Key to enter the
inlet nut adaptor more than is necessary, as there is a Particle
Screen housed under this inlet nut adaptor. This important
component of the valve will be re-used and must not be
damaged in this process.
3(f)
Screw the Multi Function Control Valve (17) to the
Nipple (29) in the tee piece. Ensure that the Particle Screen is
fitted to the entry point of the Multi Function Control Valve.
Although, thread tape is not required when screwing the Multi
Function Control Valve to the nipple, as the nipple will seal
onto the “O” ring on the Particle Screen, thread tape can be
used if this method is preferred.
