INSTALLATION
General
Installation must be carried out in accordance with these instructions, and must
be conducted by designated, qualified and competent personnel.
1.
Before commencing, ensure that the installation conditions comply with the
information given in the specification section.
2.
Care must be taken during installation to prevent any risk of damage.
3.
The hole in the basin must be a minimum of 29 mm up to a maximum of 40 mm
diameter, with a basin thickness of 30 mm maximum.
4.
The Thermostatic mixing valve should be positioned for easy access during use
and maintenance. All routine maintenance procedures can be conducted with the
Thermostatic mixing valve body in place.
5.
Conveniently situated isolating valves must be provided for maintenance.
6.
Pipework dead-legs should be kept to a minimum.
7.
Supply pipework layout should be arranged to minimize the effect of hydraulic
restriction or other outlet usage upon the dynamic pressures at the Thermostatic
mixing valve inlets. Recommended minimum supply line pipe diameter is 1/2”
or 15 mm.
8.
Inlet threaded joint connections should be made with PTFE tape or liquid
sealant. Do no use oil-based, non-setting jointing compounds.
9.
To eliminate pipe debris it is essential that supply pipes are thoroughly flushed
through before connection to the Thermostatic mixing valve.
Procedure
(Refer to Figure 1)
1.
Screw the fixing studs fully into the Thermostatic mixing valve body.
2.
Place the ‘O’ seal in the groove in the basin of the Thermostatic mixing valve
body and place the Thermostatic mixing valve into the hole in the basin.
3.
Place the flexible inlet tails through the larger holes in the backplate.
4.
Screw the flexible inlet tails into the Thermostatic mixing valve from under the
basin and tighten.
5.
Pull the backplate over the fixing studs.
6.
Made sure that the Thermostatic mixing valve is in the correct position and
screw the fixing nuts onto the fixing studs. Tighten the fixing nuts.
7.
Select the correct orientation of the insert washers. This is dependant on the type
of unions used to terminate the supply pipework.
-For flat-faced unions remove the ‘O’ seals and place the insert washers into the
checkvalve assemblies small end first.
-For 15 mm compression unions place the insert washers, complete with ‘O’
