IMPORTANT SAFETY INFORMATION

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

READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.

Installation of this equipment should be performed by a licensed
electrician and conform to all National Electric Code (NEC),
state and local codes. Installations in Canada must comply to
CEC requirements.

WARNING:To reduce the risk of electrical shock:

• Turn off or disconnect the power source before installing,
opening the door, or adjusting the internal workings of
the controller.

• Install all electrical equipment at least 10 feet (3 m) from
inside wall of pool or spa.

• Connect this device only to a grounding-type receptacle
protected by a ground-fault circuit interrupter (GFCI).

• Do not use an extension cord, connect the controller
directly into the outlet. Do not bury the cord.

WARNING:To reduce risk of injury, do not permit children to use
this product unless they are closely supervised at all times.

For proper operation, it is imperative that the system has proper
flow past the sensors when the pool filtration system is running.

When automating a body of water, size the feeders so desired
levels can be attained in short operating cycles. If feeders are
unable to keep up with demand within a short time frame,
automation becomes ineffective.

Always test and adjust sanitizer and pH to acceptable levels
before activating a new system. Automated chemical controllers
are designed to maintain water chemistry, not balance the pool.

While the system is feeding, inaccurate sanitizer/pH levels may
be displayed because the system is still circulating the chemical.

Chemical Automation System

Congratulations on the purchase of your new ORP/pH controller
and thank you for choosing Polaris. The Polaris Watermatic
C1500 Controller automatically monitors and maintains either
the sanitizer level or the pH balance in swimming pools, spas, or
any circulating water system that requires water chemistry
management. Designed for easy installation and simple
operation, it can be used with liquid feed pumps, granular
feeders, tablet erosion feeders, and ozone generators. It is not
warranted or recommended for use with chlorine gas systems.

During the filtration cycle, the controller maintains sanitizer
levels or pH balance by constantly measuring the Oxidation­Reduction-Potential (ORP) and pH balance of the water. If the
sanitizer level (ORP) or pH falls below a predetermined set
point, the controller activates the chemical feeder.

Settings and measurements are displayed on an easy-to-read
LCD text screen and adjustments are made via a touch key pad.

Flow Switch/
Flow Indicator

The flow cell houses the sensors and provides a sample port
for manual testing. It also contains an integrated flow switch/flow
indicator that prevents the feeder from feeding if there is
insufficient flow. If flow is insufficient, a warning message will
appear on the screen.

Controller Installation

Before installing the controller, do a site assessment to consider
where and how you will mount the unit. The controller should be
mounted on a wall or other flat surface within eight feet of the
feeder, at least ten feet away from the edge of the water and
within six feet of the GFCI power source. Use mounting screws
or anchors to mount the controller.
