Warning:
SAFETY GLASSES MUST BE WORN WHILE OPERATING THIS INSTRUMENT.
OPERATION:
- Close the
inlet valve (3002a) and bleeder valve (3003) on the bottle and
fill with water to the top of the bottle. The bottle and liquid
should be cooled to the temperature of the product to be tested.
This will help produce an even fill from the tank.
- Place a bottle
cap (beer crown closure) on the bottle and crimp in place with
a bottle capper.
- Attach the
bottle at the inlet valve (3002a) to the CO2 Gas Header (4000).
The assembly is now attached to the CO2 gas supply tank.
- Invert the
bottle and open the bleeder valve (3003). Now turn on the CO2
gas and open the inlet valve (3002a). The water will be completely
expelled by the CO2 gas.
- Close the
bleeder valve (3003) and establish a counter-pressure of 30 psi
in the bottle.
- Close the
inlet valve (3002a) and remove the bottle from the gas supply
and Gas Header (4000)
- Submerge
the bottle under water and observe for gas leaks.
- Attach the
clamping device (2037) to the inlet valve of the Sample Bottle.
Make sure that the neoprene gasket (2038) is properly seated in
the swivel nut (2039) of the Clamping Device before attaching
the Clamping Device to the Sample Bottle.
- Attach the
Sample Bottle/Clamping Device unit to the trycock of the tank
being tested. To do this rotate the U-bolt nut (2045) on the Clamping
Device to open the U-bolt to its most outword position. Place
the U-bolt of the clamping Device over the boss of the trycock
on the test tank.
- Close the
U-bolt tightly against the trycock by turning the U-bolt nut in
the proper direction.
- Open the
trycock and the inlet valve, allowing the excess gas to blow back
into the tank and purge the trycock line.
- Slightly
open the bleeder valve so as to allow the gradual release of gas
and the quiet filling of the sample bottle with the product.
- Allow the
bottle to overflow and close both inlet and bleeder valves in
this order.
- Remove the
Sample Bottle from the trycock.
The Sample Bottle
is now ready for CO2 and air testing and should be inserted in the
Zahm New Style Air Tester w/ Dial Thermometer (Series 7000) for
these tests. General practice is to remove 20cc of liquid by inverting
the Sample Bottle and opening the bleeder valve. If very accurate
tests are desired, correction should be made for the volume of the
sample removed. For further instructions on air and CO2 testing
refer to the Operating Instructions of the Zahm Series 7000 Piercing
Device.
