F. PAUSE TIME KNOB: Sets the delay interval from 1 to 10 seconds between dispensing cycles.
G. FLOW DIRECTION SWITCH: Sets the direction of the rotation of the pump Clockwise/Counterclockwise.
H. RUN STATUS JACK: Located on the rear panel of the units. The jack contacts are rated for 24 volts at 1 amp. These
contacts can operate remote relays to start or stop other equipment being utilized in conjunction with the dispensers.
Pump contacts are normally open when the pump is not running and closed when the pump is running. A 3.5 mm stereo
plug (part no. B-3968, not included with the pump) can be ordered for easy access to the pump status jack contacts.
NOTE: The signal common for the speed control voltage and current inputs is referenced to earth ground.
SETUP
Unpack the pump and retain all packing material until proper product operation has been verified. Select the tubing
according to the flow desired, while considering chemical compatibility and tubing life. Refer to the enclosed Chemical
Resistance Chart (part no. A-1299-5030) to select appropriate type of tubing for the liquid in use.
TUBING SIZE SELECTION
Flow rate and dispensing volumes are determined by the size of the tubing in the pump head. When tubing links are
used, best performance will be achieved when input and output tubing connected to the link are the same ID as the link.
All tubing inside the pump head must be surface-printed MANOSTAT tubing.
KATE and SPENCER pumps accept tubing ID sizes of 1/32 in. to 5/16 in. For best results, select a tubing size with a
mid-range at the desired flow rate to be pumped. The table below gives an average of flow rates measured with water
at standard pressure and temperature. No lift or discharge pressure is represented.
