Masterflex L/S MFLX07519-05 Manual De Operación página 7

Two Cartridge sizes (0.72 in and 0.36 in thick) (see Figure 3) accommodate a broad range of tubing sizes as noted in
Tables 1 and 2.
(1) Select Cartridges
NOTE: These Pump Heads are designed to work with the Model 07519-70 and 07519-80 Cartridges. Do not use Model
07519-75 or 07519-85 Cartridges, which are designed for different Pump Heads.
Depending on which Pump Head is used, up to four large or eight small tubing Cartridges can be teamed up with the
Pump Head. But there is a limit depending on available drive power and pump load. For full tubing flow rates at 0 psi, the
table in Appendix B shows cartridge capacities according to tubing size and drive Type (see Appendix A for description of
Drive Types). Cartridge sizes can be intermixed as long as the total load does not exceed the drive capability.
The small Cartridge is designed to operate with MASTERFLEX
accommodate specially designed Microbore Tubing Sets (.9 mm wall — see Tables 1 and 3). The small Cartridge can be
used with either the three- or the four-roller Pump Head.
The large Cartridge is designed to operate with MASTERFLEX
®
L/S 17, with either the three- or four-roller Pump Head (see Tables 2 and 3).
Use only MASTERFLEX Precision Tubing and Microbore Tubing Sets with MASTERFLEX Pumps to ensure
optimum performance. Use of other tubing may void applicable warranties.
(2) Load Cartridges
Easy, snap-in mounting and quick-release removal come with a Cartridge system—no tools required. Since the Car-
tridges function uniformly in either direction, Cartridge orientation is not important. However, you may wish to alternate
Cartridges so that the Adjustment Knob on each is easier to turn when several small Cartridges are mounted close to-
gether.
WARNING: Turn off drive before removing or installing Cartridges. Safety guards are provided to minimize risk
of fingers getting caught between the roller mechanism and the base of the module. However, be
safe—Keep your fingers away from these areas.
CAUTION: Use only tubing/cartridge combinations defined by Tables 1, 2, and 3. Use of other combinations
could cause malfunction or damage to the pump.
With the drive stopped, follow this procedure to install Cartridges.
1. Turn the Occlusion Adjustment Knob (see Figure 4) counterclockwise to maximum open. This step is not necessary
when the occlusion is set at the factory setting or if the occlusion has already been set appropriately during previous
pumping.
2. Set the Tubing Retainer according to tubing size (see Figure 6A) when using the large Cartridge. No retainer adjust-
ment is required when using the small Cartridge. (Note: The retainer button located on the Occlusion Adjustment
Knob-side of the large Cartridge is a loose component and may fall out. To reassemble, push it back into place while
pressing in the button.)
