INSTALLATION

ACCESSORIES

TROUBLESHOOTING

1. Remove the two #10 hex head screws from the back of 

the enclosure and attach mounting bracket to enclosure.

2. Select the proper location for the control panel and hang 

enclosure on a flat vertical surface or other support. When

mounting the enclosure, be sure to use hardware capable 

of supporting its weight. 

NOTE: The main feed may enter through any one of the 

1-3/4 inch knockouts at the bottom or back of the 

enclosure. A dimple is positioned on the top of the 

enclosure for piloting a drill to create an overhead 

entrance into the panel. The main feed must also pass 

through a listed outdoor conduit hub, mounted at the time 

of installation.

3. Prepare the necessary conduit runs, terminate them at both

ends and pull in the conductors as specified by the 

installation layout.

*If this control is to be used for direct connection 

to under-water lights, a Nonmetallic Hub Kit shall be used.

Order 156PA13713A for a 1/2” Kit, 156PA13714A for a 

3/4” Kit or 156PA13715A for a 1” Kit.

4. Refer to Figure 1 below. 

Note that though this figure

shows a P1353ME Digital

Time Clock installed, the 

P1353ME is not included on 

all models. See door panel for the specific configuration 

and rating of the model you are installing. A breaker base 

for up to four full size circuit breakers is included on all 

models. To wire the panel, follow the wiring diagram 

located inside the enclosure door. When the P1353ME,

make sure that the connections are tight (25 lb.-in.

minimum) and insulation clears the pressure plate

(see illustration).

5. If required by the heater manufacturer, the P1353ME

includes a connection for a fire-man switch. This switch 

only works in conjunction with circuit #1 (Load #1) on 

the P1353ME. Refer to pages 6 & 7 of the instruction 

manual for connection information, and refer to page 28 

for fireman switch programming information. Use at least 

#18 AWG wiring with insulation rated 300 volt or higher. 

Some heaters may require a special connecting harness,

contact heater manufacturer for details. Place heater 

ON/OFF switch on heater to ON position.

6. To install additional wiring devices  inside the enclosure,

first remove rectangular knockout(s) in dead front. Next,

remove hex head screws in back of enclosure and install 

stand-offs* in place of screws. Attach wiring device to 

stand-offs.

*Stand-offs are not furnished. Order 21T156A for a set of 

four (4) stand-offs and mounting hardware.

7. If external bonding is required, install a bonding lug at 

bottom of enclosure and bond installation according to 

code requirements (Order 156T11047A for Bonding 

Lug Kit).

8. Testing of the installation is optional and recommended 

only if the desired loads are securely in place and will not 

be damaged by this test:

a. Turn ON power at breaker panel.

b. P1353ME display should fully illuminate and then start 

to blink 12:00 a.m. Time clock will not blink only if time 

has been maintained by internal battery.

c. Push each of the ON/OFF buttons to verify devices 

cycle on and off. In case of unsatisfactory results, turn 

OFF power, check your wiring, refer to Troubleshooting on 

Page 3.

9. Install front panel over wiring compartment. The control 

is now ready for programming, see OPERATION section 

on Page 4

IMPORTANT SAFETY INSTRUCTIONS

When installing and operating this product and other associated equipment, basic safety precautions should always be followed,
including the following:

1. Read and follow all instructions.
2. This control must be installed by a qualified electrician, according to National and Local Electrical Codes.
3. Install this control not less than 5 feet (3 meters in Canada) from inside edge of pool. USE COPPER CONDUCTORS ONLY.
4. Do not exceed the 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. This control should not operate any equipment which would cause bodily injury or property damage should it be activated unexpectedly.

External Wired Remote Accessory

Part Number 133PE1484A

(not included with all models)

The New Intermatic Wired Remote Control allows 

you to control the P1353ME  from a remote

location. Included with the Wired 

Remote Control is a label arrangement 

allowing you to identify each button 

specific to your pool or spa equipment

pad. The new wired remote control 

comes standard with 100 foot of cable

and is designed to slip fit into any 

standard 1 1/2” conduit adapter. This 

remote works in conjunction with the 

P1353ME and displays feedback information on the

present state of the pool or spa equipment pad.

For more information refer to instructions provided

with the accessory.

Freeze Probe Accessory

Part Number 178PA28A

(not included with all models)

The New Intermatic Freeze

Probe allows you to protect

your pool or spa equipment

during an unexpected freeze

condition. The freeze probe

comes with a 10 foot cable

and  plugs into the back of the

new P1353ME. The P1353ME

can be programmed to turn on

each or all-individual loads at any desired

outside temperature.

Heater Protection (Fireman) Switch is

standard with each P1353ME.

It comes standard with a Fireman Switch

connection for your pool or spa heater.

Simply connect the two wires from the

heater thermostat to the back of the

P1353ME. The fireman switch is only 

associated with circuit one on the

P1353ME, therefore the filter pump should

be connected to circuit one. Program the

time desired for the cool down period and

the P1353ME will take over.

For more details, refer to instruction 

manual.
