Do not exceed the maximum working pressure of the lowest rated system component. • Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose Graco hoses to temperatures above 200 F (93 C) or below 0 F (-18 C). • Do not lift pressurized equipment. - Page 4 Fire, Explosion, and Electric Shock Hazard Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and resulting fire or explosion and serious injury. • Ground the equipment. • Proper grounding dissipates static electricity generated in the equipment. •...

Page 5: General Description
General Description The CycleFlo II is a pneumatic pump controller that allows precise control over the cycle rate of the pump and therefor the flow rate. The pump cycle is initiated by a 120 volt signal. The pump cycle may be initiated by some other piece of equipment such as a timer or a pH controller. -

Fig.1 - Electrical Diagrams Cycle Rate 120 Volt Adjustment Signal Relay Solenoid Valves Pneumatic Connections The integrated air valves, have a common air inlet (1/4" NPT) port and two outlet ports A and B (1/4” Tube) toward the front of the unit. The exhaust is silenced with a muffler. Do not exceed 120 psi at the air inlet to the unit. - Page 7 Husky 205. On pumps larger than the Husky 205, a three way solenoid valve (Graco Part Number 115606 or equivalent) MUST be installed on the main air supply to the pump. This ensures that pressure is not generated by the pump when the controller is not operating.

Page 8: Setup & Adjustment
One pump cycle consists of a momentary pressurization of each one of the two diaphragms. Adjustment The CycleFlo II comes with a cycle rate adjustment relay that can be adjusted using a screwdriver to control the Electric Shock Hazard energizing and deenergizing rate of the built-in solenoid valves. -
Page 9: Operation
Operation Priming the Pump Prime the pump by applying a 120 Volt signal to the controller to allow the temporary operation of the pump. This cycle rate may be increased or decreased to facilitate pump priming. Shut off electrical supply before making adjustments. -
