the screw on the peristaltic pump. The pump works during
the fill cycle and rinse cycle.

RINSE PUMP ADJUSTMENT AND PRIMING
· The rinse pump is standard equipment on all JET-TECH machines and automatically injects
rinse additive into the rinse water for the final rinse.
· The rinse pump is located
in the base of the machine
near the booster tank. The
front, lower panel (below the
door) snaps off to access the
rinse pump. Cut the cable
tie, route the tube out from
the base of the machine and
drop the clear vinyl hose and
filter into your rinse additive
container. (Some models are
supplied with a rinse additive
bottle that fits inside the
base of the machine)
Adjustments should be made clockwise to reduce the amount of rinse additive and counter
clockwise to increase the amount of rinse additive.
· If air gets in the rinse hose or if the pump stops drawing additive from the container, the pump
may need to be primed.
To Prime (accelerate the injection of chemical) the pump, follow these steps;
1) Turn OFF the machine, pull the overflow, and drain
the wash tank. The wash tank must be empty has

2) Get access to rinse-additive pump (see above
instructions) Turn the adjusting screw on the rinse
pump approximately 10 turns counter clockwise,
allowing maximum travel for the piston. The screw
may fall out but this is not a problem. Just remember
how many turns you had made when the screw fell
out.
3) Turn the machine ON and count to 5, then turn the
machine OFF and count to 5, do this several times,
until the liquid is drawn up the tube to the rinse pump.
