INSTRUCTIONS<br />
<strong>NRIBV</strong><br />
The <strong>NRIBV</strong> range of non return isolation valves (NRI) combine the non-return and isolating functions in one<br />
simple campact valve. The <strong>NRIBV</strong> range is available in 15mm and 20mm and with optional female, flare and<br />
nut and copper olive compression ends.<br />
The <strong>NRIBV</strong>S range of non return isolating valves incorporate a line strainer which is designed to protect any<br />
down stream valves and or equipment. The removable strainer prevents grit and debris from entering the line.<br />
Features<br />
• Suitable for horizontal or vertical installation<br />
• Forged DR brass body<br />
• Complies with AS1357.1<br />
• Watermark Certification<br />
• Easily visible on or off quarter turn handle<br />
• Removable strainer for cleaning<br />

The tempering valve may be installed at the point<br />
of use, but there must be a minimum 1 metre<br />
pipe run between the valve and the outlet tap.<br />
Caution: Water escaping from the drain line may<br />
be hot and could cause scolding. This valve is a<br />
Safety Valve. Excessive discharge from the drain<br />
line or operation of the small auxillary relief<br />
valve opposite the drain can mean a malfunction<br />
within the system. Switch off the energy source<br />
and call a plumber or service person.<br />
