1. SAFETY
WARNING!
Before installation, be certain the appropriate gauge has
been selected considering operating pressure/full scale pres-
sure/proof pressure, wetted material requirements, media
compatibility, operating temperature, vibration, pulsation,
desired accuracy and any other gauge component related to
the service application (including the potential need for pro-
tective attachments and/or special installation requirements).
Failure to do so could result in equipment damage, gauge
failure and/or personal injury. Only qualified personnel should
be permitted to install and maintain pressure gauges.
2. INSTALLATION
When installing the gauge connection into the application,
use the wrench area (above the threaded portion) to thread
in and tighten the gauge. Do not use the gauge case to
install the gauge. This could result in loss of accuracy,
excessive friction, or mechanical damage to the pressure
element or gauge case.
The gauge connection must be compatible with the mating
connection and must be assembled appropriately. If the
mating parts do not seal completely, a sealing material may
be considered.
After installation, pull up the blue cap on the fill/vent plug
to the full open position. Opening the vent plug will relieve
internal pressure changes in the gauge case that otherwise
would have been induced by environmental changes in
pressure and/or temperature. Without being vented this
change in internal pressure could adversely affect the accu-
racy of the gauge. If liquid filled, only open vent plugs when
the plug is oriented in the vertical position.
3. STORAGE
Gauge should remain in original packaging until installation.
This will protect from mechanical damage as well as
environmental conditions. Storage temperature range from
-40 °F to 158 °F (-40 °C to 70 °C).
4. MAINTENANCE/REPAIRS
Check regularly to ensure the gauge is in good working
order. When removing the gauge from the application make
sure there is no pressure in the system and all system media
has been isolated from the gauge. If gauge is damaged or
out of calibration a new gauge must be installed.
These gauges are not to be re-calibrated.
Misuse or misapplication of this gauge could result in gauge
failure, equipment damage and/or personal injury.
Install with a
9/16˝ (63mm gauge)
or 7/8˝ (100mm gauge)
open end wrench.

5. FRONT FLANGE AND U-CLAMP MOUNTING
Installation Instructions for 8008 Front Flange Mounting Kit
1. Align any screw hole with gauge fill plug and press flange
onto back of case until it touches front ring. To prevent
warping, press evenly around perimeter of flange as it forms
around case.
2. Drill panel hole for gauge, and drill 3 clearance OR tapped
holes (120° apart) for mounting screws (see table for sizes).
3. Use hardware provided to secure gauge to panel.
NOTE: Use an open end wrench on the gauge process
connection when connecting gauge to pressure source.

Installation Instructions Type 8008 U-Clamp Mounting Kit
1. Drill panel hole for gauge (see table for sizes).
2. Place gauge through panel. Assemble bracket onto process
connection using square keyway, then shift bracket to
engage into groove of process connection.
3. Install screws (provided) through bracket and tighten onto
panel until gauge is secure (5 - 7 in-lbs).
NOTE: Use an open end wrench on the gauge process
connection when connecting gauge to pressure source.
