1. DESCRIPTION
This installation and operation manual covers the series AK M80/86 crossover manifold. The AK M80/86
crossover manifold is used to maintain a continuous supply of source gas when the “in use” gas cylinder
is depleted by automatically drawing gas from a standby cylinder. The AK M80/86 consists of a
crossover regulator and a line regulator mounted to a common panel. The crossover regulator consists of
two regulators with separate inlets and a common outlet, machined into a single body. Two pressure
gauges are installed in the crossover regulator to indicate the inlet pressure from the A Side and B Side gas
cylinders. The crossover regulator supplies the line regulator. The crossover regulator has a plugged outlet
port at the 6:00 o’clock position for installation of a relief valve. A relief valve is recommended to protect
the low pressure side of the crossover regulator from full cylinder pressure in the event of a seat failure.
The line regulator has one primary outlet port, a secondary plugged outlet port, and a pressure gauge that
indicates outlet pressure. Custom configurations may vary slightly from this standard design. Figure 1
shows the basic design.
