1. Installation

If the switchover system seems to be using gas from the primary and reserve cylinders (pressure is

de creas ing on both inlet gauges at the same time), do the following:

1. Make sure the priority valve knob is turned fully to the right or left.

2. Observe the inlet pressure. It may be necessary to do this during the heaviest use of the system.

If the inlet pressure is below the values listed below, replace the high-pressure cylinders. If liquid

cylinders are used and the inlet pressure increases signiﬁ cantly when the system is not in use,

then the system is over-withdrawing the liquid cyl in ders. Additional capacity may be added to the

system to prevent this.

3. If the above does not ﬁ x the problem, please contact a CONCOA customer service personnel.

Please be prepared to give the following:

Model number

Gas service

Inlet pressure and type of gas supply

Outlet pressure

Approximate gas usage
