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.

• This equipment is not intended for intrinsically safe areas.

• Keep the dispense area free of debris, including solvent, rags, and gasoline.

• If there is any static sparking or you feel an electric shock while using the equipment,

stop operating immediately. Do not use the equipment until you have identified and corrected the problem.

• Make sure all electrical work is performed only by a qualified electrician.

• Have any checks, installation or service to electrical equipment performed by a

qualified electrician only.

• Make sure all electrical equipment is installed and operated in compliance with local and applicable codes.

• Make sure power is disconnected when servicing and repairing equipment.

• Keep liquids away from the electrical components.

• Disconnect electrical power at the main switch before servicing the equipment.

• Never exceed maximum wattage of the supply unit.

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. An isolation relay may be required in some installations. Always follow local and applicable electrical codes. The CycleFlo II will halt the pump cycle whenever the 120 volt signal is removed.

Installation

Electrical Connections

An access hole with a strain relief installed has been provided for the external power connection. Due to the unique requirements of each installation, access holes have not been provided for the other optional external wiring

connections such as the external air supply

Fire, Explosion, and Electric Shock Hazard

To reduce the risk of fire, explosion, or electric shock:

• The power source conduit is not an adequate grounding for the system. The unit must be grounded to a true earth ground.

• A qualified electrician must complete all grounding and wiring connections and check the resistance.

• Refer to your local code for the requirements for a “true earth ground” in your area.

valve signal. Have a qualified electrician determine the proper strain relief, wire type, and wire size for your particular application. When positioning or adding access holes, be careful not to damage any internal components. Failure to use the proper strain relief, wire type and wire size can cause damage to internal components or personal injury.

There are three connections on the 120V input signal terminal block (see Fig. 1). The two righthand connections are for line and neutral wires respectively. The left-hand connection is for a true earth ground.
