5.3. Pulse Timer Pumps
If the pump was purchased with the pulse
timer mode the pumps rate control knob
will adjust the pumps run time per pulse

and 1.2 to 60 seconds.
The pump is also provided with a 10 foot
(3 meter) signal cable with two bare leads.
The input is a dry contact, compatible with
contacting head type water meters and
the input has no polarity. No voltage is
permitted on the input signal.
5.4. Dry Contact Input Pumps
If the pump was purchased with the Dry Contact Input mode, the pump will be
activated and deactivated by this dry contact input. The pump is provided with
a 10 foot (3 meters) signal cable with two bare leads. The input is a dry

5.5. General Operation
DANGER:
DO NOT ATTEMPT TO FEED CHEMICALS WITHOUT FIRST
CONSULTING YOUR CHEMICAL FEEDER DEALER OR CHEMICAL
SUPPLIER. To avoid running out of chemical, follow a regular schedule of
monitoring chemical supply.
CAUTION: Inspect peristaltic tubing frequently and replace when deterioration
becomes apparent. Peristaltic tubing will eventually wear and break if neglected.
This occurrence will cause chemical spillage and a potential for personal injury or
damage to equipment. Always refer to chemical manufacturers
recommendations with regards to safety and handling of hazardous or corrosive
chemicals. Always wear protective clothing and safety glasses when working
near chemical feed systems.
WARNING:
Do not expose the pump or tubing to pressure exceeding the
pressure rating on the pump nameplate.
1. Make sure the rocker switch is in the off/neutral position...
2. Fill the chemical tank with the chemical to be fed.
