Advanced Operation
Pressing [] will place a running pump in HOLD and a holding pump in
RUN.
Do not charge or operate the pump with the charger in hazardous locations.
9. Obtain the calculated back pressure by adding one inch to the highest back pres-
sure number and rounding up to the next number. The additional inch allows for
typical back pressure fl uctuations.
Example using two tubes:
Flow Back Pressure
Tube Port (ml/min) (in H
2
O)
1 A 20 6.2
2 B 50 7.9
Calculated back pressure is 9 (7.9 + 1 = 8.9 rounded to 9).
10. Reinsert opened representative tube #1 back into port A. Place unopened tubes
in remaining port(s) to “seal” them.
11. Reset the pump to the desired fl ow rate for port A as done in Step 6.
12. While the pump is still in RUN, press  to scroll to Constant Pressure reading
(ins or mm). Use a screwdriver to turn the fl ow adjust screw clockwise for port A
on the Adjustable Low Flow Tube Holder until the display matches the calculated
back pressure. Press [] to place the pump in HOLD.
13. Repeat Steps 10 through 12 for remaining port(s).
14. Place the pump in Multiple Tube (Constant Pressure) mode. From RUN, press
[] to place the pump in HOLD,  (security code), and .
