ADVERTENCIA:
PROFESSIONALLY TRAINED AND QUALIFIED SERVICE PERSONNEL THOROUGHLY FAMILIAR
WITH INDUSTRY SERVICE PROCEDURES AND SAFETY PRECAUTIONS AND HAVING THE
NECESSARY EQUIPMENT TO PERFORM THE SERVICE PROPERLY. ALL EXTINGUISHER AND
SERVICE EQUIPMENT COMPONENTS, FITTINGS AND ADAPTERS MUST BE IN GOOD CONDIITON
AND PROPERLY CONNECTED.
Disconnect the regulator from the agent cylinder. Visually examine the regulator and high pressure hose
1.
for signs of damage, corrosion or deterioration. To perform the regulator static pressure, dead set and
minimum pressure flow rate checks:
a. Connect the proper service kit Adapter to the low pressure outlet port of the regulator.
b. Connect the service kit Hose Assembly and Flow Chamber to the regulator low pressure port
adapter.
Make sure all service kit connections are secure and that the kit flow chamber is CLOSED. Check the
2.
argon cylinder pressure to ensure that it is within the acceptable operating range. Hold the kit flow
chamber in one hand and slowly open the argon cylinder (with either "T" handle operating lever or by
turning the handwheel if so equipped). Observe flow chamber pressure reading to see if it is within the
recommended static dead set pressure parameters for the Models 680 & 681 regulator listed below.
Tipo de Regulador – Victor
Presión de Estática – 120 ±10psi
Mínimo Flujo de Presión – 110 psi minimo
ADVERTENCIA: IF THE PRESSURE READING EXCEEDS THE GIVEN PARAMETERS, QUICKLY
CLOSE THE ARGON CYLINDER "T" HANDLE OR HANDWHEEL VALVE AND VENT THE
PRESSURE BY OPENING THE FLOW CHAMBER BALL VALVE. REGULATORS CANNOT BE FIELD
ADJUSTED. THEY MUST BE REPLACED IF FOUND TO BE OUT OF TOLERANCE.
Observe the proper regulator static dead set pressure for a minimum of one minute, then fully open the
3.
flow chamber valve for 1-2 seconds. Observe the pressure reading to ensure that the flow pressure does
not drop below the minimum specified. Close the argon cylinder valve after the test and vent the flow
chamber pressure by opening the flow chamber valve.
Prior to performing the minimum flow check, make sure that the argon cylinder valve ("T" handle
Note:
or handwheel) is FULLY OPEN so that it does not restrict or alter the flow readings.
ADVERTENCIA: ALWAYS OPEN THE SHUTOFF NOZZLE HANDLE SLOWLY. ANY PRESSURE IN
THE AGENT CYLINDER WILL CAUSE THE EXTINGUISHER TO DISCHARGE. BE PREPARED FOR
A POSSIBLE DISCHARGE AND NOZZLE RECOIL. ANY EVIDENCE OF AGENT IN THE NOZZLE
INDICATES THAT THE UNIT MAY HAVE BEEN USED AND THE USE NOT REPORTED.
Disconnect the discharge hose from the agent cylinder. Check the couplings, hose and hose gaskets for
4.
damage or deterioration – replace as necessary.
To perform an operational integrity check on the discharge hose and nozzle combination:
5.
a. Connect the test kit hose adapter to the female end of the discharge hose.
b. Close the discharge nozzle shut-off lever and properly secure it.
c. Connect a properly regulated and verified argon pressure source, set to the extinguisher
operating pressure (110-130 psi) to the test kit hose adapter.
d. Slowly pressurize the discharge hose/nozzle assembly to the extinguisher operating pressure and
check for leaks or distortion.
e. Operate the nozzle lever to ensure proper operation and to clear the hose of any obstructions. If
hose is obstructed - refer to Troubleshooting Guide.
f. Close the argon pressure source and slowly relieve remaining pressure by fully operating the
nozzle lever.
Remove the agent cylinder cap and examine it closely for any signs of damage, cracks or thread wear.
6.
Clean the agent cylinder fill cap threads and thread vent port on the cap with a stiff bristle nylon brush.
Remove the fill cap gasket and check for wear, cracks or tears – replace if necessary. Lightly lubricate
the gasket with Visilox and reinstall.
THE FOLLOWING STEPS SHOULD ONLY BE PERFORMED BY
