Product Usage Instructions
Safety Precautions:
WARNING!
Always pressure test for leaks to ensure all connections are properly sealed.
Installation:
- When installing the gauge connection, 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 to prevent loss of accuracy or damage to the gauge.
- Ensure compatibility of the gauge connection with the mating connection and assemble it appropriately.
Storage:
Keep the gauge in its original packaging until installation to protect it from
mechanical damage and environmental conditions.
Maintenance and Repairs:
- Regularly check the gauge to ensure it is in good working order.
- Before removing the gauge from the application, release all pressure in the system and isolate system media from the gauge.
- If the gauge is damaged or out of calibration, replace it with a new one as these gauges are not meant to be re-calibrated.
Venting:
- After installation, the vent plug can be cut to relieve internal pressure changes in the gauge case induced by environmental pressure and temperature changes.
- If liquid-filled, only open vent plugs when the plug is in a vertical position.
FAQ:
-
Q: Can the gauge be re-calibrated if it is out of calibration?
A: No, these gauges are not to be re-calibrated. If a gauge is out of calibration, it should be replaced with a new one. -
Q: How should I store the gauge before installation?
A: Keep the gauge in its original packaging until installation to protect it from mechanical damage and environmental conditions.
Always Pressure Test for Leaks to Ensure All Connections are Sealed.

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 protective 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.
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, the vent plug can be cut to 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 accuracy of the gauge. If the liquid is filled, only open vent plugs when the plug is oriented in the vertical position.
STORAGE
The gauge should remain in its original packaging until installation. This will protect from mechanical damage as well as environmental conditions.
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 the 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.
Always Test the System for Leaks to Ensure All Connections are Properly Sealed.
