MOTHER TANK, TRANSFILLER & CALIBRATION

CYLINDER CONNECTED FOR TRANSFILLING

(Figure 3)

1. Remove the safety cap or caps from the calibration mother tank.

2. Very slowly, open valve on the calibration mother tank a very small

amount (crack). Then close it immediately. This will clean (blow) any

contaminants out of the valve.

3. Firmly secure the hex nut on the calibration transller to the calibration

mother tank valve outlet using an appropriate wrench. (Note: notches

in hex nut body indicate the nut threads are “Reverse Cut” threads.)

4. Tighten small hex nut on calibration transller to valve outlet on

calibration cylinder.

5. Close bleed off valve on calibration transller by turning it completely

clockwise.

6. Slowly open calibration mother tank valve counterclockwise until

the pressure gauge on the calibration transller continues to rise, or

approximately one-half of a turn open.

7. Observe calibration transller pressure gauge and turn off calibration

mother tank valve at 1750 psig or when the pressure gauge stops rising

below 1750 psig level (determined by calibration mother tank internal

pressure). DO NOT EXCEED 1750 psig pressure in the calibration

cylinder.
