Maximum operating pressure

4.4 System check

The GT tank must be bypassed if the system
pressure exceeds the maximum operating pressure
of the GT tank during a system check.

4.5 Isolating valves

We recommend installing an isolating valve on either
side of the GT tank.

4.6 Installing the relief valve

1. Set the relief valve to open at the maximum
operating pressure. This will protect the GT tank
and other system components.
2. Install the relief valve at the connection of the GT
tank to the pipe system. It should have an outlet
equal to the pump capacity at maximum operating
pressure.
