NOTE: The filling temperature must not 65°C.
Higher temperature will cause a higher dome of the membrane disc!
The pressure difference across the diaphragm holder during charging should not exceed 30
bar = 430 psi.
This means the flow of gas shall be controlled continuously, starting slowly to build up the
cylinder pressure.
RECOMMENDED PROCEDURE:
1. Prepare the cylinder for charging, i.e. protection cap is removed, check the adapter is clean
inside and insert the diaphragm holder by hand
2. Weigh the empty cylinder, i.e. the cylinder with the diaphragm holder and write the weight
onto the label.
3. Charge CO
2
until the correct weight and write the weight on the cylinder label
4. The charged cylinder is disconnected from the charging connection and is weighed again.
Write the total weight on the cylinder label. The operator signs and dates the label.
5. The diaphragm holder is tightened by means of a torque spanner to a torque of approx. 40-
50Nm (29-36 foot pounds).
6. The gas tightness must be checked by pouring a small amount of alcohol over the
diaphragm holder while the cylinder is vertical. No bubbles must be seen.
7. The protection cap must now be fitted.
HOW TO USE THE SETUP:
When the diaphragm holder has been opened in accordance to the manual to allow charging,
valve position 1 is slowly opened until the pressure, indicated on gauge position 2, raises to a
maximum of app. 30 bar= 430 Psi. Listen to the flow noise. When it stops or reduces, you can
gradually open more and in this way keep the charging running until fully charged.
If you have to disconnect when changing to another gas, you can follow two procedures using
two different set ups:
Set up 1. Valve pos. 1 and gauge pos. 2
Close the diaphragm holder and valve # 1. Disconnect from one gas to another gas supply, open
for the supply, open the diaphragm holder and watch the pressure on gauge pas. 2. Slowly open
valve pas. 1 and raise the pressure to a maximum of 30 bar = 430 psi above the cylinder pressure
or until the charging weight is obtained. Close the diaphragm holder according to the manual.
Set up 2. Valve pos. 1 & 3 and gauge pos. 2.
The setup has an extra valve pos. 3, which is closed instead of the diaphragm holder and the
cylinder pressure will remain visible on the gauge while changing. This set up will save the seal
ring of the diaphragm holder for extra operations.
