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 transfiller 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 transfiller to valve outlet on
calibration cylinder.
5. Close bleed off valve on calibration transfiller by turning it completely
clockwise.
6. Slowly open calibration mother tank valve counterclockwise until
the pressure gauge on the calibration transfiller continues to rise, or
approximately one-half of a turn open.
7. Observe calibration transfiller 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.
