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.
Electrical 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.

designed for installation and service by properly trained personnel.
Use all required personal protective equipment when working on or near a
metering pump.
Install the pump so that it is in compliance with all national and local plumbing
and electrical codes.
Use the proper product to treat potable water systems, use only additives listed or
approved for use.
Inspect tube frequently for leakage, deterioration, or wear. Schedule a regular pump
tube maintenance change to prevent damage to pump and/or spillage.

MOUNT PUMP
Select a dry location (to avoid water intrusion and pump damage) above the
solution tank.
To prevent pump damage in the event of a pump tube leak, never mount the
pump vertically with the pump head up.
DO NOT mount pump directly over an open solution tank. Keep tank covered.
Avoid flooded suction or pump mounted lower than the solution container. Draw
solution from the top of the tank. Pump can run dry without damage. If pump is
installed with a flooded suction, a shut-off valve or other device must be provided
to stop flow to pump during service.
To prevent motor damage, verify with a volt meter that the receptacle voltage
corresponds with the pump voltage.
Plug cord into receptacle and turn the pump on.

Suction Line
INSTALL SUCTION LINE TO PUMP HEAD
1. Uncoil the suction/discharge line. Use outside of solution tank as a guide to cut
proper length of suction line ensuring it will be 2-3" above the bottom of solution tank.
Allow sufficient slack to avoid kinks and stress cracks. Always make a clean
square cut to assure that the suction line is burr free. Normal maintenance
requires trimming.
Suction lines that extend to the bottom of the tank can result in debris pickup
leading to clogged injectors and possible tube failure.
2. Make connections by sliding the line(s) through connecting nut and ferrule and finger
tighten to the corresponding tube fittings.
3. Finger tighten nut to the threaded tube fitting while holding the tube fitting.
Over tightening the ferrule and nut with a wrench may result in damaged fittings,
crushed ferrules, and air pick up.
DO NOT use thread sealant tape on pump tube connections or tools to
tighten connections.
DO NOT use pliers.

INSTALL SUCTION WEIGHT TO SUCTION LINE
1. Drill a hole into the bung cap or solution tank lid. Slide the tubing through and
secure the weighted strainer to the line.
2. To attach the strainer, push approximately 3.5" of suction line through the cap on the
strainer body. Pull tubing to make sure it is secure.
3. Suspend slightly above tank bottom to reduce the chance of sediment pickup.
DO NOT mix additives in the solution container. Follow recommended mixing
procedures according to the manufacturer.
DO NOT operate pump unless additive is completely in solution. Turn pump off
when replenishing solution.

INSTALL DISCHARGE LINE TO PUMP HEAD AND INJECTION POINT
1. Make a secure finger tight connection on the discharge fitting of the pump head as
instructed in Install Suction Line instructions.
DO NOT use thread sealant tape on pump tube connections or tools to
tighten connections.
HAZARDOUS PRESSURE: Shut off water or circulation system
and bleed off any system pressure.
Locate a point of injection beyond all pumps and filters or as determined by
the application.
2. A 1/4" or 1/2" Female NPT (FNPT) connection is required for installing the injection
fitting. If there is no FNPT fitting available, provide one by either tapping the pipe or
installing FNPT pipe tee fitting.
3. Wrap the Male NPT (MNPT) end of injection fitting with 2 or 3 turns of threading tape.
If necessary, trim the injection fitting quill as required to inject product directly into
flow of water.

4. Hand tighten the injection fitting into the FNPT fitting.
a. Install connecting nut and ferrule to the pump discharge tubing. Insert discharge
tubing into injection fitting until it reaches base of fitting.
b. Finger tighten connecting nut to fitting.
5. Turn pump on and re-pressurize system. Observe flow as actuated by system and
check all connections for leaks.
6. After suitable amount of dosing time, perform tests for desired readings (e.g., pH or
ppm). If necessary, fine tune dosing levels by rotating potentiometer or by adjusting
solution strength.
The injection point and fitting require periodic maintenance to clean any
deposits or buildup. To allow quick access to the point of injection, Stenner
recommends the installation of shut-off valves.
