Safety Precautions and Repair
2.1 44-6800E Series Regulator Safety
Do not attempt to select, install, use or
maintain this regulator until you have read
and fully and understood these instructions.
Do not permit untrained persons to install,
use or maintain this regulator.
The 44-6800E Series regulator should not be installed
in an enclosure that is heated above the regulator’s
maximum rated ambient temperature.
Be sure this information reaches the operator and
stays with the product after installation.
Improper selection, improper installation, improper
maintenance, misuse or abuse of regulator can
cause death, serious injury and property damage.
Possible consequences include but are not limited to:
•
High velocity fluid (gas or liquid) discharge
•
Parts ejected at high speed
•
Contact with fluids that may be hot, cold, toxic or
otherwise injurious
•
Explosion or burning of the fluid
•
Lines/hoses whipping dangerously
•
Damage or destruction to other components or equipment
in the system
Safety Precautions
•
Inspect the regulator before each use.
•
Never connect regulators to a supply source having a
pressure greater than the maximum rated pressure of the
regulator, valve or accessory.
•
Refer to product label (model specific) for maximum inlet
pressures . If this rated pressure cannot be found, contact
your local TESCOM representative for the designed
pressure rating of all equipment (e .g., supply lines,
fittings, connections, filters, valves, gauges, etc.) in
your system . All must be capable of handling the
supply and operating pressure.
•
Install circuit protection on input voltage to electrical
controls of the regulator per local and environment
codes.
•
Clearly establish flow direction of the fluid before
installation of regulators, valves and accessories. It is
the responsibility of the user to install the equipment in
the correct direction.
•
Remove pressure from the system before tightening
fittings, gauges or components.
•
Never turn regulator or valve body. Instead hold
regulator or valve body and turn fitting nut.
•
Take precautions before touching the regulator while
in operation.
•
If a regulator or valve leaks or malfunctions, take it out
of service immediately.
•
Do not modify equipment or add attachments not
approved by the manufacturer.
•
Do not open enclosures when energized. Do not open
enclosures when explosive atmosphere may be present.
•
For pressure reducing regulators, it is highly
recommended that the control knob or adjusting screw
be turned fully counterclockwise before applying inlet
pressure.
•
Apply pressure to the system gradually, avoiding
a sudden surge of fluid or pressure shock to the
equipment in the system.
•
Regulators are not shut-off devices. Install a pressure
relief device downstream of the regulator to protect the
process equipment from overpressure conditions. Shut
off the supply pressure when the regulator is not in use.
•
Periodic inspection and scheduled maintenance of your
equipment is required for continued safe operation.
•
The frequency of servicing is the responsibility of the
user based on the application. Never allow problems
or lack of maintenance to go unreported.
•
Read and follow precautions on compressed gas
cylinder labels.
•
It is important that you analyze all aspects of your
application and review all available information
concerning the product or system. Obtain, read and
understand the Material Safety Data Sheet (MSDS)
for each fluid used in your system.
•
Never use materials for regulators, valves or accessories
that are not compatible with the fluids being used.
•
Users must test components for material compatibility
with the system operating conditions prior to use in
the system.
•
Vent fluids to a safe environment and in an area away
from personnel. Be sure that venting and disposal
methods are in accordance with Federal, State and
Local requirements. Locate and construct vent lines
to prevent condensation or gas accumulation. Make
