including the following:
1. This Control must be installed by a qualified electrician, according to the National Electrical Code (Including Article 680) and
Local Electrical Codes.
2. USE COPPER CONDUCTORS ONLY. If applicable, install this Control not less than 5 feet from inside edge of pool or spa.
3. Do not exceed the maximum ratings of individual components, wiring devices, and current carrying capacity of conductors.
4. For grounding of the installation, refer to Article 250 and 680 of the National Electrical Code.
5. This Control should not operate any equipment which would cause bodily injury or property damage should it be activated unexpectedly.
6. Always disconnect electricity at main panel before servicing this Control or the equipment connected to it.
THIS CONTROL IS NOT TO BE USED AS A POWER DISCONNECT.
READ, FOLLOW AND SAVE THIS INSTRUCTION MANUAL
INSTALLATION
1. Select the proper location for the Control Panel
and prepare the necessary conduit run(s)
required by the installation layout.
2. Remove the four #10 hex head screws from
the back of the enclosure and attach mounting
brackets to enclosure.
3. Hang enclosure on a flat vertical surface or other
support, using hardware suitable for the purpose.
4. Properly terminate
conduits at both ends

conductors as specified
MAKE SURE INSULATION
by the installation layout.
CLEARS PRESSURE PLATE
5. Follow wiring diagram on page 4 of this
Manual. Connect LINE 1 and LINE 2 of the
240 Volt supply conductors to time switch
terminals 1 and 3 (see insert above for proper
connection) and the grounding conductor to
the Equipment Grounding Terminal.
6. Connect Filter Pump leads to terminals 2 and
4 of Filter Pump Time Switch. Connect the
grounding lead of the pump to the Equipment
Grounding Terminal at the bottom of the
enclosure.
7. If the Control Panel is installed in a 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!
8. If external bonding is required, install a bonding
lug at bottom of enclosure and bond installation
according to code requirements.
9. TEST INSTALLATION:
a. Turn thermostat dial to its lowest setting
and place crushed ice (in plastic bag) inside
capillary coil of Thermostat.
b. Turn ON power to Control Panel, wait
20 seconds then slowly turn thermostat dial
counterclockwise until Filter Pump starts.
c. Turn OFF power to Control Panel,
remove ice, check wiring, tighten terminal
screws if necessary, reinstall time switch
insulator and front plate.
d. Turn ON power to Control Panel and
set Time Switch and the Thermostat,
see OPERATION instructions on page 3.

TO SET FILTER PUMP TIME SWITCH, follow
instructions on the right. The length of the daily filtration/
heating cycle depends on many variables such as size, shape,
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, pointing to desired
temperature, marked on the plate, between 32˚F and 45˚F.
Again, many variables must be considered before selecting
the "turn ON" temperature of the Filter Pump and 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.

OPERATION
TIME SWITCH OPERATING INSTRUCTIONS
1. TO SET "ON" AND "OFF"
TIMES: Hold TRIPPERS against
edge of CLOCK-DIAL, pointing
to time (AM or PM) when ON
and OFF operations are desired.
Tighten tripper screws firmly.
2. TO SET TIME-OF-DAY:
Pull CLOCK-DIAL outward. Turn in either direction and
align the exact time-of-day on the CLOCK-DIAL (the time
now, when switch is being put into operation) to the pointer.
• TO OPERATE SWITCH MANUALLY: Move
MANUAL LEVER below CLOCK-DIAL left or right as
indicated by arrows. This will not affect the next operation.
• FOR MORE THAN ONE DAILY ON-OFF
OPERATION: Place additional tripper pairs on
CLOCK-DIAL (order 156T1978A).
• IN CASE OF POWER FAILURE: Reset CLOCK-
DIAL to proper time of day. See step 2 above.
