2-8 IPT122 Indicating Pressure Transmitter Mechanical Inst allation

Failure to follow these procedures may adversely affect the product’s
performance and could void the product warranty . Inspect but DO NOT
unwrap any parts until installation. Contact your Brooks representative with
any problems.

1. Unpack the pressure transmitter
Determine that the desired IPT unit is listed on the packaging. Do not open

if the package does not contain the proper device.

Section 2 Installation

IPT122 Series

The IPT is double-bagged for cleanroom service and should remain
packaged until installation.

Do not remove the pressure transmitter from the protective bag unless you
are in a clean environment.

A. Remove pressure transmitter from the box and carry it into the gray

area.
B. Remove and discard the outer protective bag.
C. Carry the pressure transmitter (sealed in the inner bag) into the clean

area.

2. Install the pressure transmitter
A. Prepare the connection fitting in place on the gas line. Any other fitting

components, such as stainless steel gaskets, should be blown clean
with a filtered gas before use.

B. Note: For installation in tight spaces, and on some regulators, it

may be necessary to remove the electronic assembly (back half) of
the IPT. This reduces the depth of the gauge by approximately 7/16".

C. Maintain a flow of at least 1 slpm (0.05 scfm) of inert gas during

installation to minimize tubing and IPT contamination from
environmental moisture and particles. The recommended purge gas
is electronic-grade Nitrogen.

D. Open the inner bag and remove the pressure transmitter. Remove

any fitting protection caps and seat the pressure transmitter on the
mating connections.

E. Tighten the nuts by hand, then 1/8 turn past hand-tight by wrench for

fittings compatible with VCR® fittings. DO NOT overtighten.

Note: Refer to specific technical guides furnished by fitting manufacturers for
additional specifications.
