SAFETY INF RMATI N continued
Warns about hazards that WILL or CAN cause minor personal
injury or property damage if ignored.
PLUMBING
Metering pump installation must always adhere to your local plumbing codes and
requirements. Be sure installation does not constitute a cross connection. Check
local plumbing codes for guidelines.
N TICE: Indicates special instructions or general mandatory action.
This metering pump is portable and designed to be removable from the plumbing
system without damage to the connections.
Before installing or servicing the pump, read the pump manual for all safety
information and complete instructions. The pump is designed for installation and
service by properly trained personnel.
Installation and product must adhere to all regulatory and compliance codes
applicable to the area.
This is the safety alert symbol. When displayed in this manual or on the
equipment, look for one of the following signal words alerting you to the
potential for personal injury or property damage.
Acceptable for indoor and outdoor use.
Acceptable pour une utilisation aussi bien à l’intérieur qu’à l’extérieur.
lectrical installation should adhere to all national and local codes. Consult a licensed
professional for assistance with proper electrical installation.
Removing power from pool/spa recirculation pump must also remove power from pump.
The use of an auxiliary safety device (not supplied), such as a flow switch or sensor,
is recommended to prevent feed pump operation in the event of a recirculation
pump failure or if flow is not sensed.
Point of injection should be beyond all pumps, filters, and heaters.
Maximum temperature = 40°C.

PERATI N
The Stennicator requires a signal from a water meter providing a dry contact at a setting of
1PPG, 10 PPG or 1 PPL. It will proportionally dose at a ratio of 1:128 (1 oz. per gallon) to
treat process flow rates up to 2.7 gpm*. At any point, the potentiometer can be turned to
the proper contacting rate setting (1 PPG, 10 PPG, or 1 PPL) to begin dosing proportionally
at the rate of 1:128.
The pump incorporates a signal repeater relay, which will repeat the incoming signal to
another Stennicator, device, or controller.
Turning the potentiometer to PRIM initiates a 60 second cycle to prime the pump. TH
PRIM CYCL HAS A 5 S COND D LAY. At the end of the PRIM cycle, the pump will stop
and will remain stopped until it is set to a contacting rate.
Turning the potentiometer to STANDBY, stops the pump and resets the PRIM cycle. To run
another PRIM cycle, set to STANDBY, then turn the potentiometer to PRIM . When the
pump is placed in STANDBY, it will not dose when it receives a signal from the water meter,
but it will still repeat the incoming signal.
The installation can be duplexed by using two Stennicator pumps to keep pace at higher
flow rates. By properly wiring the signal cables (details in the installation section) each
pump will deliver at a ratio of 1:256 (0.5 oz. per gallon) to achieve a ratio of 1:128 (1 oz.
per gallon). This will allow a ratio of 1:128 up to flows of 5.4 gallons per minute.
*At flow rates above 2.7 gpm the pump will run during its cycle and miss the next meter dry contact. It will
restart when it receives the next dry contact.
