tion to reverse flow direction.* A center
“OFF” position on this switch provides
system off facility.
*Preferred pumping and dispensing direction
is from left to right when facing the pump head.
2. CAM ADJUSTMENT - Your QC
Dispenser hand/foot switch relates di-
rectly to a Cam Q502 actuated Limit
Switch Assembly Q501. This is timed
to the piston suction position. To ad-
just, loosen mounting Screws 110477-
10 on Terminal Strip 110476. Adjust
Limit Switch Assembly to Cam Q502
so that you get 2 clicks per revolution.
Tighten screws 110477-10 on Termi-
nal Strip.
3. CALIBRATION - Hook-up inlet and
outlet tubing, set mode switch in down
(PUMP) position and clear the pump
of bubbles (see FMI Q431 instructions
and Parts Identification sheet, Sec.
12).
Calibration for specific shot volumes is
rather straightforward.
a) Determine volume required per
shot.
b) Estimate approximate percentage
of maximum per shot flow for your
particular pump head, i.e., -3 or 1/2”
piston pump heads at 100% = 1.28
ml per shot, -2 or 3/8” piston pump
heads at 100% = 0.72 ml per shot, -
1 or 1/4” piston pump heads at 100%
= 0.32 ml per shot and -0 or 1/8”
piston pumps at 100% = 0.08 ml per
shot.
c) When approximate setting is
made, pump 20 shots into a cali-
brated receiver (pipette, burette,
graduate), and divide the measured
volume by 20 to find the exact per
shot volume. If your volume is too
low, increase stroke volume by turn-
ing the STROKE LENGTH ADJUST-
MENT KNOB Q464 counterclock-
wise. If too high, decrease by turning
clockwise. Repeat calibration check
as you fine-tune to your requirements.

INSTRUCTIONS
& PARTS LIST
1. OPERATION - The QC has three
switches to control its functions:
a) An air-activated hand/foot switch
at the end of a 6’ long hose. This
switch starts and stops each operat-
ing cycle. It can be operated by hand,
foot, or other remote pressure means.
b) A mode switch in the up or dis-
pense position. This switch permits
only one dispense or aspirate per
squeeze of the hand/foot switch. The
pump will make a complete uninter-
rupted dispense cycle once hand/
foot switch is squeezed and held and
will reset itself when released. The
down or pump position permits the
unit to operate continuously as a
pump. The hand/foot switch is inop-
erable in this mode.
c) A direction switch controls the
direction of fluid flow through the
pump head when the hand/foot switch
is squeezed, i.e., pushing the direc-
tion switch to the FWD or up position
will cause flow in that direction when
the hand/foot switch is squeezed.
