1.1 IMPORTANT SAFETY INFORMATION

!

PLEASE READ THIS USER MANUAL completely before installing or operating the equipment. The Smart
pHTM is a Class 1 product for protection against electric shock and a Type 1 product with regards to disconnection of
the control circuits.

Observe the following safety precautions:

 Do not permit anyone untrained or under the age of 18 to use this product.

 Unit must be properly connected to earth ground.

 Never apply power when front panel is not secured in the closed position.

 Never service unit with power applied, always turn OFF main circuit breaker to unit and all

equipment when servicing.

 Touching the controller’s internal parts could result in injury and or damage to the controller. In case of a

malfunction, only a qualified technician should repair the controller.

 Risk of Electric Shock. Connect only to a grounding type receptacle protected by a ground-fault circuit

interrupter (GFCI).

 Do not bury cord. Route cord to eliminate abuse from heater exhaust, lawn mowers, hedge

trimmers, and other equipment.

 Be careful not to damage any of the insulation on wires or the power cord. Should the cord be damaged

return it to your dealer for a replacement. Continued use could result in fire or electric shock.

 To reduce the risk of electric shock, do not use an extension cord to connect unit to electric supply;
provide a properly located GFCI.

 Never remove or install any cables between the circuit cards when power is applied, damage to the
components may occur.

WARNING

CHEMICAL BURN HAZARD - Make sure pumps are OFF before drilling into pipes. Securely fasten all
electrical, water and chemical lines. Locate chemical feed pumps and chemical storage tanks in a safe and secure area.
Never turn chemical feed pumps ON when any valves are closed. The feed lines can blow off and spray full strength

chemicals causeing damage to property and cause serious injury or death.

WARRANTY

Acu-Trol, Inc. warrants the Smart pHTM to be free from defects in manufacturing and workmanship for a period of
ONE (1) YEAR from the date of manufacture for the electronic module. All sensors and flow cells have a ONE (1)
YEAR from the date of manufacture. Other equipment is covered by the individual manufacturer’s own warranty.
During the warranty period, any defective parts will be repaired or replaced when necessary by Acu-Trol, Inc.

This warranty does not cover: (a) the buyers’ labor or any servicing fees related to replacement of the Product; (b)
damage resulting from the use of this Product in other than its normal manner; (c) damage from misuse, accident or
neglect; (d) damage from improper testing, operation, or installation; (e) not operating the Product on a dedicated
(separate) circuit or under conditions other than those recommended or at voltages or amperages other than the
voltage or amperage indicated on the Product; and (f) acts of Mother Nature (i.e. lightning, electrical storms, floods,
etc.). In addition, attempting to service or modify the Product will render this Warranty Void. Defective parts should
be returned immediately to the local Acu-Trol dealer, any parts returned to the factory require a return of material

SUMMARY: The Smart pH is a microprocessor based, modular automation system capable of
continuous local monitoring and control of the pH water chemistry for pool and spa
applications. The Smart pH will maintain the pH levels (either increasing pH using base

or decreasing pH using acid) of your water system automatically. The Smart pH will

only increase or decrease the pH. The Smart pH is recommended for use with a
chlorine generator or an erosion type feeder. You can also use the Smart pH when hand

feeding liquid chlorine (base) or muratic acid as the chlorine will increase the pH and

the acid will decrease the pH. The Smart pH can also control CO2 gas systems with the
same efficiency as an acid feed controller. (For specific information on installation refer
to documentation supplied with CO2 chemical feeder).

RELAY: The Smart pH has one relay module to control the pH levels.

SENSORS: The Smart pH can measure inputs from one pH sensor.

VOLTAGE: The Smart pH can only work on an input voltage of 110 VAC.
