1. SAFETY
WARNING!
Before installation, be certain the appropriate gauge has
been selected considering operating pressure/full scale
pressure/proof pressure, wetted material requirements,
media compatibility, operating temperature, vibration, pul-
sation, desired accuracy and any other gauge component
related to the service application (including the potential
need for protective attachments and/or special installation
requirements). Failure to do so could result in equipment
damage, gauge failure and/or personal injury. Only quali-
fied personnel should be permitted to install and maintain
pressure gauges.
2. INSTALLATION
When installing the gauge connection into the applica-
tion, 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 accu-
racy, excessive friction, or mechanical damage to the
pressure element or gauge case.
The gauge connection must be compatible with the mat-
ing 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 other-
wise would have been induced by environmental chang-
es in pressure and/or temperature. Without being vented
this change in internal pressure could adversely affect
the accuracy 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 installa-
tion. 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 sys-
tem 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.
