TECHNICAL MANUAL
Dishwashers
A separate grease interceptor is recommended for each commercial dishwasher. The size of the interceptor is determined by
the GPM discharge rate of the dishwasher as specified by the manufacturer. Select proper interceptor of equivalent or next
higher rate from Table 8.3 .2.
Multiple Fixtures
Where multiple fixtures are served by a single interceptor calculate the interceptor size per section 8.3.1 or, calculate the
capacity of each fixture and total the fixture capacities up, or establish the total capacity of the maximum number of fixtures
that may be drained simultaneously. Then using the GPM capacity calculated proceed with sizing of the interceptor to the
nearest PDI size, larger than the calculated capacity based on a one minute or two minute drain down time.
