4
Connect the waste T-piece (6) to the Inlet Pressure Relief Valve and
Tundish (4) using the flexible plastic hose (7). The Tundish has a water
trap in order to prevent odours from escaping from the waste pipe.
3
Turn the stop valve (the small knob) on the Inlet Pressure Relief
Valve to ‘OFF’ the turn on the mains water supply and check the
assembly for leaks, and rectify as necessary. Once this check
has been carried out, turn off the mains water supply again. The
expansion discharge of the Inlet Pressure Relief Valve and the
tundish must always point downwards and remain unobstructed.
1
Install the 15mm stop valve included in the Water Filter
Assembly (10). Determine the position to fit the 15mm
Compression Tee (3) in the mains water pipework. Determine
where the waste Tee piece (6) will be connected to the sink
plastic waste pipe.
Important note:
There must be a minimum
distance of 500mm between the bottom of the tundish and the
inlet of the waste connector. If a waste disposal unit is installed,
the waste water from the tundish must be piped to discharge
directly into the soil stack, rather than the sink waste.
Install the 15mm compression Tee (3)
and the waste saddle connection (6).
2
Install the Filter Housing (10) to the 15mm compression Tee
(3) Connect the Inlet Pressure Relief Valve (4) to the outlet of
the filter. (Note there is an arrow in the top of the filter head
indicating the direction of flow). Secure the filter unit securely
using the bracket and screws provided.
Important note:
If the
bracket is not employed the weight of the filter unit when full
of water, will put undue strain on the pipework. The distance
between the Pressure Relief Valve inlet and the boiling water
heater must never exceed 1.5 metres.
