1.0 SAFETY: When installing and using this electrical equipment, basic safety
precautions should always be followed, including:

1.1 WARNING !: To reduce the risk of injury, do not permit children to use this product

unless they are closely supervised at all times

1.2 WARNING !: Risk of electric shock.
Connect only to a grounding type receptacle protected by a ground-fault circuit interrupter
(GFCI). Contact qualified electrician if you cannot verify that the receptacle is protected by a
GFCI and that your installation meets local electrical codes, including grounding of water
system components.

1.3 WARNING !: Risk of electric shock.
Do not bury electric cords. Locate cord to minimize abuse from lawn mowers, hedge trimmers,
and other equipment. Replace damaged cords immediately. Do not use extension cords.

1.4 WARNING !: Risk of electric shock.
Install at least 10 feet (3.0m) from inside wall of water enclosure using non-metallic plumbing.
Do not install this controller in a location accessible to the public.

1.5 WARNING !: Risk of Chemical Overdose/Exposure.
Removing power from circulating pump must also remove power from the controller.
Provide a properly located outlet controlled by the circulating pump circuit.

1.6 WARNING !: Risk of electric shock/pinching/chemical exposure.
Remove power sources or lockout circuit prior to performing maintenance on controller.

1.7 WARNING !: Risk of Chemical Overdose/Exposure
Use a device such as a flow switch to shut-off power from the controller in the event of
circulating pump failure. It is unsafe to automatically dispensed chemicals into a circulating
system that is not running.

1.8 WARNING !: Risk of Chemical Exposure.
Pool water must be balanced and stabilized before operating this controller.

1.9 WARNING !: Risk of Chemical Overdose/Exposure
Minimize amount of chemical on site that is available to dispense.
Size the feeder and container to pool/spa capacity.
Dilute chemical for small bodies of water.

1.10 WARNING !: Risk of Chemical Exposure
Do not shut down circulating and control system immediately after using pool, spa or hot tub.
Systems must operate until water chemistry is stable. Systems must be restarted before water
chemistry is out of NSPI recommended ranges or water chemistry must be manually
corrected.

1.11 WARNING !: Controller uses microprocessor.
Wireless communication equipment or other electrical devices operated in close proximity
may cause inadvertent actuation of chemical feed pumps.

2.0 QUICK START REFERENCE

Use this section for reference - please read all safety instructions and appropriate manual
sections for installation and operation instructions.

• Do NOT add chemicals to feeders until all start-up operations are completed.

• Manually adjust and balance pool/spa to acceptable levels and verify using DPD test

kit prior to start-up. Automation should be used to maintain chemical levels, not to
balance a pool/spa that is out of acceptable chemical ranges.

On/Off:

• Press the Mode button to turn the unit on.

note: ‘FLOW’ light must illuminate.

• Press and hold the Mode button to turn the unit off.

“OFF” will be displayed in the windows

To Operate:

• Press and release the mode button until the “AUTO” light is lit.

Unit will now operate in the factory preset ORP settings:

- Set level: 650 mV

- Feed times: 0.6 second feed with a 5 minute delay

- Limits/Alerts: 900 mV (High) & 100 mV (Low)

To Change Settings:

• Press and release the Mode button –AUTO light off.
Note: Once the settings are changed, they will remain at
those settings until they are manually changed again.

Set Level: press the Set Level button until the desired set point is reached.
Feed Time: press the Feed Time button until the desired feed time is reached.
The number represent the seconds of feed time (all with 5 minute delays).
Range is 0.6 to 900 sec. (15 min.). Constant feed is ‘con’.
Hi Alert: press and hold the Mode button then press Set Level button (red ORP alert
LED will come one), release both buttons. Use Set Level button to increase or
decrease the ORP Hi Alert. Press Mode button to continue.
Low Alert: press and hold the Mode button then press Set Level button (red ORP
Alert LED will come one), release both buttons. Use Feed Time button to
increase or decrease the ORP Low Alert. Press Mode button to continue.
