CHLORINE GAS BUILDUP CAN OCCUR WITH IMPROPER WIRING:

To reduce the risk of personal injury the IntelliChlor® Electronic
Chlorine Generator (IECG) Power Center must be installed on and
wired to the load side of the time clock, electronically controlled switch,
or relay load side, so that it will receive power only when the pool
pump is on. Otherwise, dangerous chlorine gas buildup can occur. The

IECG should never be energized when the pool pump is OFF and
water is not flowing through the unit.

To reduce the risk of injury, do not permit children to use or operate this
pump and sand filter.

When setting up pool water turnovers or flow rates the operator must
consider local codes governing turnover as well as disinfectant feed
ratios.

DO NOT increase pump size; this may increase the flow rate through
the system and exceed the maximum flow rate stated on the drain
cover. Never operate the IntelliChlor Electronic Chlorine Generator
(IECG) without proper flow or water circulation. A build-up of
flammable gases will result in hazardous conditions.

Operate unit with minimum flow of 25 gpm. For high flow
applications, use a bypass loop.

WARNINGS AND IMPORTANT SAFETY PRECAUTIONS

Never operate the IntelliChlor Electronic Chlorine Generator (IECG)
without proper flow or water circulation. A build-up of flammable
gases will result in hazardous conditions. Operate unit with
minimum flow of 25 gpm. For high flow applications, use a bypass
loop.

Only use pipe couplings that meet Schedule 80, maximum pressure
150 psi at 70° F.

RISK OF ELECTRICAL SHOCK OR ELECTROCUTION:

Always disconnect power to the IntelliChlor salt chlorine generator
at the circuit breaker before servicing. Failure to do so could result
in death or serious injury to service person, pool users or others
due to electric shock.

IntelliChlor Electronic Chlorine Generator (IECG) is for use with
permanently-installed pools and may also be used with hot tubs
and spas if so marked. Do not use with storable pools. A
permanently installed pool is constructed in or on the ground or in
a building such that it cannot be readily disassembled for storage.
A storable pool is constructed so that it is capable of being readily
dissembled for storage and reassembled to its original integrity.

The IECG Power Centers must be interconnected with the pool
pump motor power source. This ensures the IECG and pool pump
will switch on and off together.

When mixing acid with water, ALWAYS ADD ACID TO WATER.
NEVER ADD WATER TO ACID.

Use of chemicals other than those recommended may be hazard­ous. Follow the Chemical Manufacturer's Instructions.

To reduce the risk of electric shock, install IntelliChlor Electronic
Chlorine Generator (IECG) a minimum of five (5) feet away from
the inside wall of the pool.

Install the IECG a minimum of three (3) feet away from the heater
outlet. Allow ample access to the IntelliChlor control panel buttons
and the IntelliChlor Power Center.

A solid copper, bonding conductor not smaller than No. 8 AWG
(8.4 mm) should be connected to all metal parts of the swimming
pool, spa, or hot tub structure and to all electrical equipment,
metal conduit, and metal piping.

Do not operate electrolytic cell without proper flow or water
circulation. A build-up of flammable gases will result in
hazardous conditions.

When using IntelliChlor with an IntelliTouch system, it is recom­mended to wire the IntelliChlor Power Center to the pump side of
the relay located in the IntelliTouch Load Center. This wiring
method does not require a ground fault circuit-interrupter (GFCI)
to protect the circuit. A green colored terminal (or a wire connec­tor marked “G”, “GR”, “Ground” or “Grounding”) is provided within
the terminal compartment in the Power Center transformer
enclosure. To reduce risk of electric shock, connect this terminal
or connector to the grounding terminal of your electric service or
supply panel with a conductor equivalent in size to the circuit
conductors supplying this equipment. The power supply must be
interconnected with pool pump motor power source. This insures
the IntelliChlor chlorinator and pool pump will switch on and off
together.

Use of chemicals other than those recommended may be
hazardous. Follow the Chemical Manufacturer’s Instructions.

Install the IntelliChlor unit a minimum of two (2) feet from the
heater outlet.

It is recommended to install a Pentair Water Pool and Spa®
two ( 2) inch CHECK VALVE (P/N 263042) between the input
side of the IntelliChlor cell and the main heater output pipe.

iii

Water temperature in excess of 100° F (37.7° C) may be hazardous to
your health. Prolonged immersion in hot water may induce
hyperthermia. Hyperthermia occurs when the internal temperature of
the body reaches a level several degrees above normal body
temperature of 98.6° F (37° C.). Effects of hyperthermia include: (1)
Unawareness of impending danger. (2) Failure to perceive heat. (3)
Failure to recognize the need to leave the spa. (4) Physical inability to
exit the spa. (5) Fetal damage in pregnant women. (6)
Unconsciousness resulting in danger of drowning. The use of alcohol,
drugs, or medication can greatly increase the risk of fatal
hyperthermia in hot tubs and spas.

IntelliChlor® Power Center Overview

The IntelliChlor electronic chlorine generator system comprises of a Power Center and
electrolytic Cell. The Power Center converts AC electrical current to a low voltage DC
current required by the IntelliChlor electrolytic cell to operate and create chlorine for the
swimming pool and spa. The Power Center is connected with the pool circulation pump
electrical source so that the electrolytic cell only operates when the pool pump is on. It is
recommended that a pool pump timer be used to save on energy and prolong the
service life of your pool pump and IntelliChlor. A timer is not included as part of the Power
Center kit. The IntelliChlor Power Center can be connected to an IntelliTouch,
EasyTouch or SunTouch system for automation control.

The Power Center enclosure can be mounted vertically on a flat surface such as a wall
or post no more than 15 feet away from the cell controller. The Power Center houses the
transformer, fuse, and connector to the cell. 110 VAC and 220 VAC wiring is connected at
this box, with 35 VDC output to the cell controller. A 10 AMP slo-blo fuse is mounted on
the bottom of the enclosure for additional protection. There are no other controls or lights
on the outside of the Power Center. A green power LED indicator is mounted on the
inside main board. When the Power Center is switched on, the power LED is lit.

IMPORTANT: When using an IntelliChlor salt chlorine generator and an IntelliFlo
pump (or 2-speed pump) with a Pentair Water Pool and Spa® IntelliTouch®,
EasyTouch® or SunTouch® automation control system , the IntelliChlor AC power
center wires must be connected to the PUMP SIDE OF THE MAIN FILTER PUMP
RELAY located in the load/power center. This ensures that the IntelliChlor cell
produces chlorine only when the main filter pump is on. See page 5 for details.

IntelliChlor System Components

An IntelliChlor Electronic Chlorine Generator IntelliChlor system consists of one or more
of the following:

• PC100 (P/N 520556): Power Center Kit. Provides power and control communication to
and from the IntelliChlor cell.

• IC20 Cell (P/N 520554): Designed for pools up to 20,000 U.S. gallons (75,000 liters).
The cell will produce the equivalent of 0.70 lbs. of pure chlorine per 24 hours of
continuous pool pump run time.

• IC40 Cell (P/N 520555): Designed for pools up to 40,000 U.S. gallons (150,000 liters).
The cell will produce the equivalent of 1.40 lbs. of pure chlorine per 24 hours of
continuous pool pump run time.

• IC60 Cell (P/N 521105): Designed for pools up to 60,000 U.S. gallons (227,124 liters).
The cell will produce the equivalent of 2 lbs. of pure chlorine per 24 hours of continuous
pool pump run time.

• IntelliChlor “dummy” bypass cell (P/N 520588): For new pool start-up.

Operating Instructions

When using a pool pump timer: The Association of Pool and Spa Professionals (APSP)

recommends that all water in a residential pool pass through the filtration system at least
once every 12 hours (referred to as pool water turnover). However, many factors have an
effect on actual pump and filter system run times. Pool size, source of water, direct sun
light, indoor/outdoor, screened and unscreened, filtration system, cold or hot weather,
swimmer load, rain, organic debris, algae, etc., are all factors which contribute to either
more or less pool pump and filter system run times. Because of these differences, it is
extremely difficult to set an initial run time (starting point) for the pool pump and
chlorinating system. Try initially setting the pool pump timer to 12 hours. It will take a few
days to get just the right amount pool pump operating time. When the Chlorinator is wired
with a pool pump timer (see page 6) results will vary greatly from one pool installation to
the next, so this should be discussed with either the pool builder or your pool
professional.
