WITH FREEZE PROTECTION IN RAINPROOF ENCLOSURE
ELECTRICAL RATING: 3 HP Max. - 240 Volt, 60 Hz.
MAXIMUM RUNNING LOAD NOT TO EXCEED 17 AMPERES
This Pool Equipment Control is designed
to automatically operate the Filter Pump
and also to provide freeze protection for
the pool equipment. Nevertheless, this
product is not intended to be a substitute
for insulation, coverings, or maintenance.
The Filter Pump Time Switch is located
in the upper r

and oper
ates the F
ilter Pump, as set by
the trippers on the yellow dial, on a 24
hour schedule. For setting the schedule,

The Freeze Protection Unit is located in
the upper left side of the enclosure and
turns ON the Filter Pump when the air
temperature (w
her
e the Control Panel is
located) drops below the temperature set
on the dial (between 32˚F and 45˚F).

OPERATION
TROUBLESHOOTING
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 enc
losure on a flat vertical surface or other
support, using hardware suitable for the purpose.
4. Properly terminate
conduits at both ends
and pull-in the
conductors as specified
by the installation layout.
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 enc
losure.
Handle capillar
y
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.
SYMPTOM
1. Time Switch will not keep
time but dial is turning.
2. Time Switch Dial stops
at ON or OFF tripper.
3. Load is ON at all times -dial is turning.
4. Dead clock motor. (Clock
motor gears do not rotate.)
5. Filter Pump will not start
when temp. is below 32˚F.

1a.Frequent power outages
1b.Wrong voltage/cycle
1c.Loose clock motor connections
2a. Loose tripper
2b.Bent dial
2c.Defective motor
