4.
Disconnect the tubing from the pump using a 9/16-in. hex wrench. Turn the hex nut
counterclockwise until the connector (with tubing attached) is released from the pump.
Do not remove the knurled nut. Doing so could damage the tubing.
5.
The pump is mounted on a tray. The tray is held in place with four retaining screws; two
at the front (where the power connector is located) of the pump and two at the back
(shown here). Loosen and remove all four screws.
6.
Remove the pump and place it on a work table.
7.
Service the pump using the instructions provided with the Service Kit.
