Wiring Access: The enclosure features 7 knockouts located on the sides, back, and bottom for flexible conduit entry. Use a hammer or knockout punch to remove the desired knockouts.
Wiring: Open the lid of the disconnect box. The lid is designed to stay open at a 90-degree angle for easier access during wiring. Connect the incoming power supply and outgoing load wires to the appropriate terminals inside the box. Ensure all connections are tight and correct according to the wiring diagram (refer to local electrical codes and the HVAC unit's manual for specific wiring requirements). The box provides ample wiring space.
GFCI Receptacle Wiring: The GFCI receptacle operates on an independent circuit. Ensure it is wired correctly according to its specific requirements.

6. Operation

6.1. Pull-Out Switch

The disconnect box features a non-fused pull-out switch for manually disconnecting power to the HVAC unit.

To Disconnect Power (OFF): Firmly grasp the pull-out handle and pull it straight out from the unit. The handle can be stored in the 'OFF' position within the unit to prevent accidental re-engagement and misplacement.
To Connect Power (ON): Align the pull-out handle with the slots and push it firmly into the unit until it is fully seated. This will restore power to the connected HVAC system.

The top part shows the switch removed, and the bottom part shows a hand inserting and removing the switch from the 'ON' and 'OFF' positions, highlighting its simple operation.

6.2. GFCI Receptacle

The integrated GFCI receptacle provides a convenient power source for temporary use with service tools during maintenance or installation.

Using the GFCI: Plug your 125V, 20A compatible tool into the receptacle.
Testing the GFCI: Periodically press the 'TEST' button on the GFCI receptacle. The 'RESET' button should pop out, indicating the GFCI has tripped. Press 'RESET' to restore power. If it does not trip, the GFCI may be faulty and should be replaced.
Resetting the GFCI: If the GFCI trips (power is interrupted), press the 'RESET' button firmly to restore power. If it trips repeatedly, there may be a ground fault in the connected tool or wiring.

Cleaning: Periodically clean the exterior of the enclosure with a damp cloth to remove dirt and debris. Do not use abrasive cleaners or solvents. Ensure the lid is closed and secured during cleaning.
Inspection: Annually inspect the enclosure for any signs of physical damage, corrosion, or loose connections. The galvanized steel construction and NEMA 3R rating provide excellent resistance to weather and rust.
GFCI Test: Test the GFCI receptacle monthly as described in Section 6.2.
Wiring Check: If comfortable and qualified, periodically check internal wiring connections for tightness, especially after extreme temperature fluctuations. Always disconnect power at the main breaker before opening the enclosure for inspection.

8. Troubleshooting

If you encounter issues with your disconnect box, refer to the following troubleshooting steps:

No Power to HVAC Unit:
- Ensure the pull-out switch is fully inserted into the 'ON' position.
- Check the main circuit breaker for the HVAC unit in your electrical panel to ensure it has not tripped.
- Verify all wiring connections inside the disconnect box are secure (only by a qualified electrician with power off).
GFCI Receptacle Not Working / Tripping:
- Press the 'RESET' button firmly.
- If it trips immediately, unplug the connected tool and try resetting. If it still trips, the GFCI may be faulty or there is an issue with its wiring.
- If it trips with a tool plugged in, the tool may have a ground fault. Try a different tool.
- Ensure the GFCI is not overloaded (maximum 20 Amp).
Physical Damage to Enclosure:
- If the enclosure is significantly damaged, it may compromise its NEMA 3R rating and safety. Consider replacement.

For issues not resolved by these steps, contact a qualified electrician or SURAIELEC customer support.
