(refer to Figure 8-1 or 8-2, depending on your pump model):
Note
Tighten fittings just enough to hold tubing in place. Final tightening
will be done after all the tubing and fittings are in place.
1. Move the pumps so that the pump bases are about 1.3 cm
apart.
2. Use the plugs to stopper the ports which will not be connected
to the continuous flow package.
DANGER

COULD BE 700 BAR. PLEASE UTILIZE
APPROPRIATE TUBING AND CONNECTIONS
NOTED IN THE MANUAL.
3. Attach the connectors appropriate to your pump to the 6.4
cm unbent stainless steel tubing lengths and use the 1 8"
nuts and ferrules to attach to the double check valve housings.
4. Attach the inlet tubing assembly. The tubing you use
depends upon whether or not your source is pressurized.
a. Pressurized Reservoir:
Connect the 1 8" 1.5 m stainless steel tubing to the
bottom of the inlet tee, using high pressure valve fittings.
Note
The filter and PTFE tubing are not used.
b. Nonpressurized Reservoir:
Connect the 1 8" 1.5 m PTFE tubing to the bottom of
each inlet check valve using the ferrule and nut with
support spring provided in the package. Attach the tubing
to the filter connector and then connect the filter.
Note
The stainless steel tubing is not used.
5. Once the contents of the continuous flow package are
totally assembled, attach the connectors appropriate for
your pump on one side of the assembly to a port. Then, supporting
the tee/valve assembly attach the other connector
to the port of the second pump.
6. Attach the outlet fittings to the top of the upper tee. Fittings
for 1 8" tubing, as well as an optional reducing fitting
