Peristaltic Pump

The peristaltic pump requires routine maintenance to ensure that the system will
run properly. The pump tubing should be replaced when flat spots develop (on a
daily basis or after approximately eight hours of use). When replacing the pump
tubing, the drain tubing should be replaced at the same time since uneven wear can
cause the spray chamber to back up.

waste out of the spray chamber. Tighten the adjustment screw (turn clockwise) up
to three turns until the bubbles are visible in the drain tubing. Then add three more
turns of the adjustment screws.
