1. Remove Knockouts

The timer enclosure features pre-stamped 1/2 inch and 3/4 inch knockouts for wiring access. Select the appropriate size for your wiring conduit.

Place a screwdriver tip on the desired knockout.
Strike the screwdriver handle with a hammer to break the knockout seal.
Use pliers to grasp the loosened knockout and twist it to remove the outer ring completely.

2. Mounting the Timer

The NEMA 3R enclosure is designed for wall mounting. Ensure the mounting surface is stable and capable of supporting the timer's weight.

Open the timer enclosure door.
Remove the internal timer module from the box by unscrewing the retaining screws.
Hold the empty enclosure against the desired mounting location.
Mark the positions for the mounting holes using a pencil or marker.
Drill pilot holes if necessary, suitable for your mounting hardware (screws, anchors, etc.).
Securely fasten the enclosure to the wall.
Reinstall the timer module into the mounted enclosure.

3. Wiring Connections

The timer switch features convenient screw terminals for secure wiring. Refer to the wiring diagram inside the enclosure for specific connections. Ensure all connections are tight and correct for your application.

Connect the incoming power supply (LINE) to the designated terminal.
Connect the load (e.g., pump, water heater) to the designated terminal.
Connect the neutral wire to the neutral terminal.
Ensure the ground wire is securely connected to the ground lug within the metal box and to the ground terminal on the timer module for continuous grounding.

Operation

1. Setting the Current Time

The timer dial represents a 24-hour cycle. To set the current time:

Gently turn the mechanism dial counter-clockwise until the current time aligns with the "SET" arrow on the timer.
Ensure AM/PM is correctly observed (e.g., 3 PM is 15 on a 24-hour dial).

2. Setting ON/OFF Trippers

The timer uses ON and OFF trippers to activate and deactivate the connected equipment. One set of trippers is included.

Locate the ON (typically green or blue) and OFF (typically red) trippers.
Insert the ON tripper into the desired "ON" time slot on the outer edge of the dial.
Insert the OFF tripper into the desired "OFF" time slot.
Ensure the trippers are securely fastened by tightening their screws. Loose trippers may shift and cause incorrect operation.
The timer will activate the connected equipment when the dial reaches the ON tripper and deactivate it when it reaches the OFF tripper.

3. Manual Override Switch

A manual override switch is provided for temporary control of the connected equipment without altering the programmed schedule.

To manually turn the equipment ON or OFF, simply toggle the override switch.
The timer will resume its programmed schedule at the next ON or OFF tripper event.

Maintenance

Regular Inspection: Periodically inspect the timer switch and its wiring for any signs of wear, damage, or corrosion.
Tripper Security: Over time, the ON/OFF trippers may loosen. Regularly check that they are securely fastened to prevent them from shifting and affecting the schedule. Tighten screws as needed.
Enclosure Integrity: Ensure the NEMA 3R enclosure remains sealed and free from damage to maintain its rainproof and tamper-resistant properties.
Cleaning: Clean the exterior of the enclosure with a damp cloth. Do not use abrasive cleaners or allow moisture to enter the internal components.
Professional Check: For any internal issues or complex repairs, consult a qualified electrician.
