•
The valve body is clearly marked with “C” and a blue indicator for cold and “H” and a red
indicator for hot.
•
The use of sealing compounds is not recommended.
•
Before installation, the hot and cold-water inlet of the mixing valve must be clear of debris.
the valve must be correctly connected to the respective supplies.
•
Isolation valves must be fitted adjacent to the valve inlet. A Pressure reducing valve (PRV)
must be fitted if deemed necessary.
•
Check the main valve assembly bores are free of debris and the end sealing faces are
clean.
•
Check the two tailpieces and confirm they are complete with union nuts and compression
nuts with olives.
•
Insert the sealing washer into the inlets and outlet and screw the inlet and outlet fittings
onto the valve body, taking care not to over tighten.
•
Remove the compression nuts and olives from the tailpieces. Locate the inlet filter screens
and insert them into the bore of the tailpieces up to the shoulder.
•
Assemble the valve to the pipe work and ensure the hot and cold-water pipes have full
penetration into the tailpieces. The compression fittings supplied allow for direct
connection to BS 22mm OD tube or BS 15mm OD tube.
