TO INSTALL THE DUAL VOLUME UNIT (DVU)

Identify a location for the DVU™ that minimizes

the length of tubing between the DVU connections
and the PPC BG0002™ TEST(+) and TEST(-) ports.
The PPC BG0002 and the DVU are designed to
stack one on top of the other. The DVU may be
rack mounted using the rack mount kit (P/N 400440).
Recommended configurations are for the PPC and
DVU to be stacked directly one on top of the other
or with their rear panels face to face.

TO CONNECT THE DVU AND PPC BG0002

You will be making and connecting two identical

assemblies, one for the TEST(+) port and one for
the TEST(-) port.

Install a union (4) into a 1/4 in. tube x 1/4 in. NPT

M adaptor (3) (do this twice). Screw the 1/4 in.
NPT M end of the adaptors into the two ports of
the DVU using Teflon

®

tape as a sealer.

Figure 1 Interconnections Kit

Install a 1/4 in. tube tee (5) onto each of the

union/adaptor assemblies that were just installed
into the DVU ports in Step

. Orient the tee
considering the connection to the PPC BG0002
(schematic above is for PPC stacked on top of
the DVU).

Install the appropriate adaptors onto the PPC BG0002

TEST(+) and TEST(-) ports:

For PPC3™ Install the 1/4 in. tube x O-seal

1/8 in. NPT M (2).

For PPC2+™ Install the 1/4 in. tube x 1/4 in.

NPT M adaptor (3) using Teflon
tape as a sealer.

Cut lengths of PFA tubing as needed to connect

the 1/4 in. tube tee to the adaptors on the PPC
TEST ports. Take care that the cut is at a right
angle to the tube and only cut the length needed.

Optional for a connection “For DUT” of 1/4 in. NPT M

rather than 1/4 in. tube:

• Cut a small length of PFA tubing to use as

a union between the 1/4 in. tube tee (5) and
the 1/4 in. tube x 1/4 in. NPT F adaptor (6)
(see schematic above).
