Description
Installation
The Reliance anti legionella valve is designed to be connected to a Reliance (Aquasystems) potable water expansion vessel with a ¾” connection. It is designed to divert a proportion of the
water that is owing through a system into the vessel to cause
turbulence and encourage an exchange of water within it.

Before installing the anti legionella valve ensure that the water system has been flushed and is free from debris and that the system pressures and temperatures are within the working parameters of the valve.
To install the anti legionella valve onto a vessel follow these steps.
1. First insert the paddle retaining tube into the vessel connection as shown. This is the small plastic tube with a cut down the side. To insert it you squeeze the tube together and push it into the vessel connection and then let it spring back into place.
2. Taking care not to damage the paddle or the paddle retaining clip, screw the anti legionella valve onto the expansion vessel and tighten up with a spanner. Note the valve includes a rubber seat so extra washers and PTFE tape are not needed.
2. Connect the ¾” FBSP tee piece onto the anti legionella valve and tighten with a spanner, the
