INTRODUCTION
The External Reservoir kit is designed for use with the
PPCH Hydraulic Pressure Controller. The external
reservoir is provided for applications requiring more
fluid than can be held in the 300 cm
3
internal reservoir.
The external reservoir is connected in series with the
internal reservoir so that internal reservoir features are
still available.

INITIAL CONSIDERATIONS FOR
INSTALLATION OF RESERVOIR
1.
Internal reservoir attachments not used:
When
using the internal reservoir, a fill tube bracket,
sight tube and funnel are mounted on the rear of
the PPCH. These attachments are not used with
the external reservoir. If the attachments are
already installed, remove them. Be sure to close
the
FILL/DRAIN
valve prior to removal.
2.
Reservoir above the PPCH:
The bottom of the
reservoir must be higher than the PPCH
instrument to ensure a proper gravity feed of fluid
to the internal reservoir and pump. Avoid low
points in the tubing between PPCH and the
reservoir.
3.
Secure the reservoir:
Pass throughs (5.4 mm Ø)
are provided in the mounting bracket for securing
the reservoir.
4.
Prepare the tubes:
300 cm of 1/4 in. O.D. PFA
tubing is provided for making tube connections
between the external reservoir and the PPCH.
The fittings on the external reservoir are 1/4 in.
Swage. The ferrules need to be swaged to each
end of the tubes.
5.
Adaptor for Reservoir return:
Use the supplied
1/8 in. NPTM x 1/4 in. Swage adaptor for the
EXTERNAL RESERVOIR RETURN
bulkhead on
the PPCH.
To prevent accidental draining of the internal
reservoir, keep the FILL/DRAIN valve in the closed
position until the external reservoir is connected.
