3.3 Filter Installation
This filter operates under pressure. When the
locking ring is properly seated and the filter is
operated without air in the water system, this filter
will operate in a safe manner.
If doubt exists as to the pressure which the system
will be subjected to, install an ASME approved
automatic Pressure Relief Valve or Pressure
Regulator in the circulation system rated for the
lowest working pressure of any of the components
in the system.
Place the filter on the concrete pad, lined up with
the inlet and outlet pipes.

local plumbing and building codes. Filter unions
are provided with an o-ring seal. Use silicone

line leaks may cause air to be entrapped in filter

line leaks may show up as equipment pad leaks or
air being discharged through the return lines.
Support the inlet/outlet pipes independently to
prevent any undue strains.
Place the union nut over the pipe and connect
the pipes to the union tailpieces using PVC
glue. Do not use teflon tape or pipe dope on any
union threads. Put the o-ring in the tailpiece and
assemble the unions to the filter tank.
If required by local code to bolt the filter to the
equipment pad, order part # R0359100 (Anchor
