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. NOTE: If the 240 Volt
supply is GFCI protected - Stop. This is not the right
control for such applications. Use Model PF1102T
instead. Otherwise connect pump to Blue and Yellow
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) con-
duit, 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.
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 equip-
ment, 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.

TROUBLESHOOTING
OPERATION
(CONT.)
3
1. Insert ON (green) and OFF (red)
trippers into dial at desired ON
and OFF times (Fig. 1).
2. Be sure trippers are firmly
pressed against dial surface
and at least one space is left
between ON and OFF trippers
(Fig. 2).
3. Turn dial clockwise one or more
revolutions until correct time of
day is next to arrow in center of
dial (Fig. 3).
Manual Knob
ON Tripper (Green)
OFF Tripper (Red)
1. The knob in the upper left corner of timer is
for operating the Filter pump manually when
needed. By turning it COUNTERCLOCKWISE,
it will start or stop the filtering/heating cycle
ahead of the scheduled start/stop time.
Automatic operation will resume with the
next scheduled cycle.
2. Timer comes with two sets of trippers, allow-
ing the choice of two cycles per day.If only
one cycle is needed, the extra trippers may
be stored on the dial by placing SAME color
trippers next to each other.
3. To suspend automatic operation, remove red
and green trippers from Dial and Store them
in a convenient place.
4. Additional trippers can be obtained by con-
tracting an Intermatic distributor or Intermatic
Consumer Service at (815-675-7000 and ask-
ing for 156PB10398A tripper kit (2 ON and 2
OFF trippers.)
