Setup & Use

Stand the cylinder upright and secure it. The valve is on the side face, so the regulator sits out to one side rather than above — useful where cabinet headroom is short.

Screw the regulator on by hand until it is firm. No tools: the seal is a washer, and a spanner damages it rather than improving it. Open the cylinder valve slowly and watch the high-pressure gauge come up.

Keep it out of direct sunlight and below 50 °C. ISTA intend it to be run with a bubble counter, a check valve and a ceramic diffuser downstream.

What's in the Box

The cylinder alone. Regulators, controllers, bubble counters, check valves and diffusers are all sold separately, and the cylinder is supplied empty — filling is done locally.
