Side-Mounted Valve Installation - Pentair FLECK 3150 NXT Installer Manual

• in any case, any failure caused by improper installations and/or piping connections may void the
warranty of Pentair products;
• in the same way, using lubricant* on the valve thread is not allowed and will void the warranty for
the valve and tank. Indeed using lubricant there will cause the valve to be over-torqued, which
may lead to valve thread or tank thread damage even if the connection to piping has been done
following the above procedure.
*Note: Use of petroleum-based grease and mineral based lubricant is totally forbidden, not only on the valve thread, since
plastics (especially Noryl) will highly suffer from contact with this type of grease, leading into structural damage hence to
potential failures.

5.5.2. Side-mounted valve installation

Valid for location having a reduced height.
Rubber expansion joint
Fleck meter
Outlet shutoff
Support tripod
• To avoid the piping supporting the valve and side adapter weight, they must be fixed on a tripod
or any other appropriate support;
• in order to adequately compensate the tank elongation, the rubber expansion joints must be
mounted on the top and bottom of the tank. In red on the diagram above.
