To reassemble the pump
1. Connect the new front panel to the chassis:
a. Install the vacuum vent fitting into the new front panel.
b. Connect the vacuum vent tubing to the front panel.
c. Lift and rotate the front panel over the solvent proportioning valves.
d. Attach the new front panel to the chassis with the three hex nuts that secured the original front panel.
Using a 1/4-in.

5/16-in. open end wrench, tighten the nuts.
2. Secure the drip tray to the chassis with the 4 screws you set aside when you removed the tray.
3. Reinstall the power switch into the drip tray.
4. Reinstall the wingnuts onto the purge valve and the pulse dampener flush valve.
5. Reinstall the tubing onto the purge valve and pulse dampener valve spigots.
6. Reconnect the crossover tube to the purge valve and left side of the LDA. Using the 8-mm wrench from the
Accela Pump accessory kit, tighten the nuts.
7. Reconnect the four solvent lines between the vacuum degasser outlets and the proportioning valves.
8. Plumb the LDA outlet to the mixer inlet (see the figure below):
a. Using two high-pressure fittings, connect the 10-cm length of stainless steel tubing between the LDA outlet
and the in-line filter assembly inlet.
b. Using two high-pressure fittings, connect the 5-cm length of stainless steel tubing between the in-line filter
assembly outlet and the mixer inlet.
The in-line filter assembly has an inscribed flow direction arrow.
9. Insert the solvent clip into its slot.
10. Reinstall the chassis into the housing:
a. Slide the chassis into the housing until it is fully seated against the rear of the enclosure.
b. Secure the chassis to the housing with the original four retaining screws. Using a #2 Phillips screwdriver,
tighten the screws.
c. Reconnect the LED cable to the left door of the housing.
