INSTALLATION
Install the interceptor as close as practical to the fixture(s) being served. Avoid installations where long runs of pipe
(exceeding 25’) are necessary to reach the interceptor. This precaution will preclude the possibility of grease becoming
congealed in the pipe before it reaches the interceptor.
The unit may be placed on the floor, partially recessed in the floor, recessed with the top flush with the floor or encased
below the floor in an appropriate housing to accommodate piping and structural considerations. Whatever the installation
method, anticipate sufficient clearance to remove the cover and baffle for cleaning. Verify that no obstructions will be
placed over the interceptor after installation. A minimum clearance equal the overall height of the interceptor (excluding
any extension) is recommended.
Do not install the grease interceptor in a waste line from a garbage grinder.
Garbage grinder waste must bypass the interceptor because the rapid accumulation of solid matter will significantly
reduce the rated efficiency of the interceptor. In an application where solids will be present, a solids interceptor should
be used.
A separate grease interceptor is recommended for each commercial dishwasher.
The size is determined by the discharge rate of the dishwasher as stated by the manufacturer.
Placement of a grease interceptor in a high traffic area is an important concern. If the unit is to be installed flush with the
floor, it is necessary to load rate the interceptor cover. The standard Wade interceptor is designed for pedestrian and
light traffic only. If heavy loads are anticipated, the interceptor must be specified with an appropriate reinforced cover. An
extension is frequently used to increase the rough-in dimension from the inlet/outlet centerline to the finished floor. The
extension anchor flange is not adequate to support the entire interceptor. For installations at flush-with-floor
level, the interceptor chamber must rest on solid ground or a concrete pad. For upper floor installations, (suspended
above the lower floor ceiling), the interceptor must be independently supported on hangers suitable to carry the entire
weight.
A single interceptor serving multiple fixtures is recommended only where the fixtures are located close together. In these
installations, each fixture should be individually trapped and vented.
