5. Orient the spacer so that the small indentation on the spacer aligns with the
inlet check valve. Then, insert the piston and seal into the pump head.
6. To seat the seal, push down on the spacer until it is flush with the head. Listen
for the clicking sound that indicates that the seal is correctly seated.
To reinstall the pump head and piston:
Thermo Fisher Scientific recommends reinstalling the head and piston as a single
assembly, so that the piston centers itself onto the magnetic follower inside the
pump housing.
1. Pull the piston partially out of the spacer
so that about 1/2 cm (1/4 in) of the shaft is
exposed. This ensures that the magnetic
follower picks up the piston when the head
is reinstalled.
2. Reinstall the head and piston assembly
onto the SP panel. Replace the washers
and screws and tighten the screws evenly.
To complete the procedure:
1. Reconnect all liquid lines to the pump head.
2. Close the waste valve.
3. Plug in the power cord and turn on the SP power switch.
4. Open the waste valve and turn on the pump.
5. Continue running the pump until no more bubbles can be seen exiting the
waste line. Close the waste valve.
6. Turn off the pump.
