DANGER

WARNING

GENERAL INFORMATION

Model PF1103T Freeze Protection Control is self-contained in an indoor-outdoor, beige, rainproof
enclosure and designed to automatically control as well as protect the Pool/Spa equipment and
plumbing against freeze damage. The Control,
if wired according to instructions, turns ON/
OFF the Filter Pump on a daily schedule and
also turns ON the Filter Pump when the air
temperature (where this Control is located)
drops below the temperature set by the ther­mostat dial (between 33˚F and 42˚F).
Nevertheless, the Control is not intended to
be a substitute for insulation, coverings or
maintenance.
Both models are designed to operate either
on 120 Volt or 240 Volt, 60 cycle. When
used on 240 Volt however, the neutral
wire must be installed and it is not
recommended for controlling 240 Volt
GFCI protected equipment. For such
application, use Model PF1102T Time
Control with Freeze Protection.

Model PF1103MT is a mechanism only,
functions just like Model PF1103T and
fits (snaps into) any Intermatic Pool
Panel, Models T10000R, T30000R or

T40000R Series.

CAUTION

Risk of injury or property damage!

Do not install or operate this equipment and other associated equipment without basic safety
precautions.
Read and follow the safety instructions listed below and other basic safety precautions before
installation or operation of this control and other associated equipment.

1. This control must be installed by a qualified person, according to the national and local electrical
codes.

2. Install this control not less than 5 feet (3 meters in Canada) from inside edge of pool and 1 foot
(30cm) above ground.

3. USE COPPER CONDUCTORS ONLY rated 75˚C minimum.

4. Do not exceed maximum ratings of individual components, wiring devices and current carrying
capacity of conductors.

5. For control grounding, bonding, installing and the wiring of underwater lights, refer to Article 680
of the National Electrical Code or Article 68 of the Canadian Electrical Code.

6. The control should not operate any equipment which would cause bodily injury or property
damage should it be activated unexpectedly.

INSTALLATION

1. Select the proper outdoor location for the Control
and prepare the necessary conduit run(s) required
by the installation layout.

2. Hang enclosure on a flat vertical surface or other
support, using hardware suitable for the
purpose.

3. Properly terminate conduits at both ends and
pull-in the conductors (Min.75˚C Rated) as
specified by the installation layout.

4. Select the appropriate wiring diagram (120V.
or 240V. installation) on page 4 of this manual
and make LINE and LOAD (Pump) connections as
shown. First identify each lead by color. The LINE
connections for 240 Volt supply are Black and Red.
To operate the clock motor and relay coil, you also
have to connect the NEUTRAL to the White lead.
Connect 240V pump to Blue and Yellow Leads,
Connect 120V pump to Blue and White Leads. Make
sure the installation is properly grounded.

5. If the Control is installed in location where it is
exposed to direct sun most of the day, extend 8
inches of the copper capillary tube of the

thermostat into an open ended (plastic or metal)
conduit, about 10 inches long, installed at bottom of
the enclosure. Handle capillary tube with care!

6. TEST INSTALLATION:
a. Turn thermostat dial to its lowest setting and
place crushed ice (in plastic bag) inside
capillary coil of Thermostat.
b. Turn power ON to Control, wait one minute
then slowly turn thermostat dial counter­ clockwise until Filter Pump starts.
c. Turn power OFF to Control, remove ice,
check wiring, reinstall front plate.
d. Turn power ON to Control and set Timer
and the Thermostat, see OPERATION
instructions on page 3.

INSTALLATION - MODEL PF1103MT

1. Install mechanism in any Intermatic Pool Panel
with only one Time Switch by snapping it into the
unused mounting bracket, furnished with the Panel.

SETTING / OPERATING INSTRUCTIONS

TO SET FILTER TIMER, follow instructions on page 3. The length of the daily filtration/heating cycle depends

on many variables such as size, shape, and geographic location of the pool, water chemistry, type of pool
equipment, usage and season of year. If not sure, contact your local pool service professional for advice.

TO SET THERMOSTAT, turn dial to desired temperature between 33˚F and 42˚F. Remember, many variables,
such as the location of this Control, the location of the pool or spa, the location and insulation of the plumb­ing, etc., must be considered before selecting the “turn ON” temperature of the Filter Pump. Your local pool
service professional is the best source of information. The Thermostat is factory set to turn OFF the Filter
Pump when the ambient temperature rises 5˚ F above its set point.
