supply wiring to the control panel. Care must be taken to ensure that the supply wiring does not interfere with the low voltage DC wiring.

The GH is supplied with a plug that functions as the disconnect device. The mating receptacle must be installed no higher than 5’ feet (1.6 m) above the floor. Make sure your installation conforms to your regional electrical standards.

Please refer to the supplied electrical schematics for detailed connection points for the supply power.

The GH system uses plant-supplied compressed air to operate the surge hopper.

CLEAN AND DRY air must be supplied to the GH System. The air supply should be filtered through a 5 micron air filter with a water separator. Oil should not be used unless air dryers are installed on the compressed air supply. In this situation, an oiler may be required on the rate monitor to keep the air cylinder seals lubricated.

Usage is about 5 cu. inches per refill.

A single 1/8” NPT standard pipe thread fitting is provide on the surge hopper solenoid to supply air.

Caution! To prevent damage to the equipment, do not exceed 60 psi (4.14 bar) air pressure.

Caution! Always disconnect the compressed air supply when working on any part of the rate monitor.
