Installation

To clean or service the filter without shutting down the

system, install a dual filter or a filter by-pass system as

explained below.

NOTE: Be sure to allow 4.5 inches (114 mm) minimum

clearance below the filter to ease removal of the filter

bowl (10).

Dual Filter System

This setup enables you to redirect the fluid to another

filter while one filter is cleaned or serviced.

Install two filters as shown in Fig 1. Both filters must

have an adapter (A) and drain valve (B) in the filter

bowl (10) to relieve fluid pressure and drain the filter

before removing the bowl. Install four suitable shut-off

valves (D), one at each filter inlet and outlet, to redirect

the fluid and isolate the filter not in use.

Filter By-pass System

This setup enables you to redirect the fluid through

pipes that by-pass the filter while cleaning or servicing

the filter.

Install the filter and by-pass pipes as shown in Fig 2.

An adapter (A) and drain valve (B) must be installed in

the filter bowl (10) to relieve fluid pressure and drain

the filter before removing the bowl. Install four suitable

shut-off valves (D), one at the filter inlet; the filter

outlet; the by-pass pipe inlet; and the by-pass pipe

outlet, to redirect the fluid and isolate the filter while

cleaning or servicing the filter.
