4. Position the buffer tube holder with the drilled hole below the pins, and fasten with (1) 1/4”-20 x
2” round head machine screw.
5. Tighten the #4-40 x 7/8” pump mounting screws from step 3.
6. Place the pump motor onto the threaded studs in the pump motor mounting block, with the pump
drive pin aligned with the coupling slot. Place the ring terminal of the green ground wire onto one
of the studs, generally the right hand stud toward the back of the analyzer. Fasten the motor and
ground wire by hand with the (2) extended brass nuts; it should be snug, but do not completely
tighten yet. The other end of the ground wire is connected in step 19, below.
7. To check the coupling and pump alignment, rotate the pump by using a slotted screwdriver to
turn the screw in the face of the pump. The pump will be somewhat difficult to turn because of
the gear reduction in the motor gearbox. If the coupling slot and drive pin in the pump weren’t
aligned, you may hear a “click” and feel the pump move in as they align and engage.
8. With the pump turning freely, tighten the motor extended brass nuts from step 6.
9. Thread the 9” long piece of black buffer tubing through the buffer tube holder and around the
three rollers on the buffer pump. The tubing should be centred front to back on the rollers. Gently
pull both ends of the tubing to remove any slack.
10. Close the curved occlusion ring, which will slightly compress the tubing onto the rollers. Secure
the ring by finger tightening the knurled head screw.
11. Place the tube stop collars onto the buffer tubing.
12. Insert the white reduction connector fittings into the black buffer tubing. They can be difficult to
insert, but do not use any lubricant on the white reduction connectors.
13. Assemble the KI solution tubing by threading one end of the clear 1/8” diameter x 5’ long piece
of tubing through the hole in the blue bottle cap and through the tube sinker. Secure the sinker
with the white reduction connector fitting; do not use any lubricant.
14. Remove the existing flushing plug from the cell block and replace it with the two-inlet flushing
plug supplied.
15. Connect the 1/8” diameter x 18” long clear buffer tubing from the left hand end of the black buffer
tubing to the fitting in the center of the new flushing plug.
16. Mount the vinegar bottle bracket on the wall as shown on page 9. The bottom of the bracket
should be about 3” above the bottom surface of the yellow electronics enclosure.
NOTE: Do not mount the vinegar bottle higher than the peristaltic pump mechanism. This could
lead to atmospheric siphoning of the buffer which can occur if the occlusion ring is loose; the
bump bearings are worn, or if the tubing has a flat spot from wear.
17. Connect the 1/8” diameter x 5’ long clear tubing for the new KI solution bottle to the right side
of the black buffer tubing. Place the other end of the clear tubing with sinker into the bottle and
secure the cap.
18. Connect the pump motor wires (blue, black and red) to the terminal block marked “KI Pump”
“TB1F” on the lower right hand side of the power supply board.
19. Connect the remaining loose end of the green pump motor ground wire to terminal “KI Pump”
“TB1F”.
20. Turn on all power sources and calibrate (see pages 26-28).
