and keep the inlet pipe as short as possible to avoid grease build-up
before it reaches the unit. If the unit is serving more than one fixture
ensure that the respective drain pipes are joined in a T-piece before they
enter the unit piping. Install "P" or "U" trap in the inlet piping from sinks
as normal. Rubber Couplings with screw clasp are included.
Outlet piping - Ensure a fall of

” per foot (1:40), only use "sweep"
connections and minimize the number of bends used. Do not reduce

possible and do not install any P-traps (the units has an in-built internal
gas trap). Note that if the unit overflows during operation the problem
