Warning:
Do not solder within 300mm of the Mixing Valve or allow solder or
flux to fall onto the casing.
Important:
An additional independent stop valve complying with the current
water regulations must be fitted in the mains water supply as a means of
isolating the supplies to the Mixing Valve for servicing and/or maintenance
work.
It is essential that all pipe work is flushed through to remove debris and
swarf that could otherwise damage the unit. Once the pipe work has been
flushed through, turn off the water supplies at the stop/service valves.
The supplied filter washers supplied
must
be fitted into both inlets.
The connecting pipe work must present 1/2 BSP connectors to the male thread on
the inlet connections.
Important:
The pipe work must run as straight as possible to the Mixing Valve
minimising 90º angled bends as this could affect the inlet pressure to
the Mixing Valve reducing performance.
Pumped Inputs
It is possible to use a pump to boost a low pressure system to meet the inlet
requirements.
Note:
The pump must be a Bristan Twin-End Negative Head Pump - ST NHPUMP
18TN.
Pump installation must be in accordance with the Fitting Instructions supplied with
the pump.
The Negative Head Pump is required to maintain the 0.5 bar minimum static
pressure requirement.
