INSTALLATION

The valve may be installed directly or remotely to a load (typically a Fan Coil Unit).The direction
of flow should be such that the PICV is on the return from the load.

PREPARATION/FITTING

Steel tube - cut square and de-burr internally and externally, thread to BS EN 10226-2 and fit to
Dominator using PTFE tape to BS7786:1995 or other recommended jointing compound. Other
types of piping system can be used providing a suitable adaptor with a threaded end is utilised.

Whilst fitting pipe and/or adapters it is important that the wrench is positioned close to
the joint to be assembled, in order to avoid damaging the valve.

The Dominator Pro shall be supported using proprietary mounting brackets or other suitable
devices see FIGURE 2 this enables the pipework to be well supported and avoids undue strain
on the joints of the Dominator Pro.
