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.

Install with a

or 7/8˝ (100mm gauge)

open end wrench.

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.
