3.6 Chemical Pump Installation
WARNING
CHEMICAL BURN HAZARD: Make sure all pumps
are switched off at the main circuit breakers at the
house before drilling into any pipes. Securely fasten
all electrical, water and chemical lines. Locate
chemical feed pumps and chemical storage tanks in
a safe and secure area.
3.6.1
Pump Accessory Checklist
•
Three (3) 1/4" connecting nuts
•
Three (3) 1/4" ferrules
•
One (1) injection check valves
•
One (1) 1/4" weighted suction line stainers
•
One (1) 20' roll of 1/4" black suction/discharge
tubing
3.6.2
Chemical Pump Safety Warnings
1. Read all safety hazards before installing or
servicing the pumps. The pump is designed
for installation and service by properly trained
personnel.
2. Use all required personal protective equipment
when working on or near a dosing pump.
3. Install the pump so that it can follow all national
and local plumbing and electrical codes.
4. Use the proper product to treat swimming pool
water systems and use only additives listed or
approved for use.
5. Inspect tubes frequently for leakage, deterioration
or wear. Schedule a regular pump tubing
maintenance change to prevent damage to pumps
and/or spillage.
6.
Pumps are not recommended for installation in
areas where leakage can cause personal injury or
property damage.

3.6.3
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.
NOTE:
Allow sufficient slack to avoid kinks and stress
cracks. Always make a clean square cut to
assure the suction line is burr free. Normal
maintenance requires trimming.
NOTE:
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 nuts and ferrules and finger tighten to
the corresponding tube fittings.
3.
Finger tighten nut to the threaded tube fitting while
holding the tube fitting.
NOTE:
Overtightening the ferrule and nut with a wrench
may result in damaged fittings, crushed ferrules
and air pick up.
NOTE:
DO NOT use thread sealant tape on pump tube
connections or tools to tighten connections.
3.6.4
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 the 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 the tank bottom to reduce
the chance of sediment pickup.
NOTE:
DO NOT mix additives in the solution
container. Follow recommended mixing
procedures according to the manufacturer.
