1. Ensure the pump is off. Lift the latch located
between the tube fittings, leaving the end of
the latch engaged with the lip on the tube
housing cover. Leave the latch on the
opposite side engaged. Illustration Q
2. Plug the pump in and turn it on. Turn the
tube fitting on the suction side not more
than 1/8 of a turn in the direction the tube
must move. Illustration R
3. DO NOT let go of the fitting until the tube
rides approximately in center of the rollers.
4. Turn the pump off, let go of the fitting, and
secure the latch between the fittings.
For CE pump only: Reinstall the safety
screw on the cover.
5. Inspect the suction and discharge lines,
point of injection, and check valve duckbill
for blockages. Clean all deposits and/or
replace parts as required. Failure to do so
may lead to poor pump performance,
including shortened tube life.
6. Reconnect the suction and discharge lines.
DO NOT allow the tube fittings to turn
inside the pump housing.
7. Turn the pump on and run for two minutes
to verify operation.
