After replacing a bottle or after making a gas connection, perform a Leak Test:
Stage1:
1.
Turn the gas OFF
2.
Using soapy water applied with a sponge, or with a brush, cover all of the gas joints with a liberal
amount of suds.
Stage 2:
1.
Turn ON the gas
2.
Adjust the pressure to between 2.7- 3.0 bar
3.
Inspect the joint for leaks
4.
If any bubbles appear, the joint will need to
be resealed.

Connect the gas hose:
Connect the braided gas hose to the top of the underbench unit via the John Guest fitting marked ‘Gas IN’ .
When commissioning, turn the gas ON by rotating the valve on top of the cylinder, anti-clockwise. Then adjust
the outlet pressure, by rotating the regulator knob in a clockwise direction, to between 2.7- 3.0 bar (green
zone)
NOTE:
The arrow should sit in the green zone of the regulator gauge; it should not fall in the red or yellow
sections.
4.3
Test for gas leaks:
When commissioning, use soapy water to perform a leak test. Apply the soapy water to the two gas
connections using a sponge or brush. If any bubbles appear and grow, there is a gas leak at the connection.
Clean away the soapy residue and tighten or refit the leaking connection. Make sure the gas is turned off
when tightening or refitting the leaking connection.
Fit the gas bottle into the cradle and secure with the Hook-and-loopstrap. Ensure the bottle is in an upright
position.
NOTE:
Care must be taken when working with high pressure carbon dioxide, and in no cases should the
normal operating pressure of between 2.7- 3.0bar be exceeded.
