- PUMP: Activates only the water pump for cooling.
- PUMP + FAN LOW: Activates both the pump and the fan at a low speed.
- PUMP + FAN HIGH: Activates both the pump and the fan at a high speed.
The specific functions available may vary slightly depending on your evaporative cooler model and whether it has a single or multi-speed motor.
6. Maintenance
The Dial 7112 Cooler Wall Switch requires minimal maintenance. To ensure continued reliable operation:
- Periodically inspect the switch and wall plate for any signs of damage or wear.
- Gently wipe the surface with a dry, soft cloth to remove dust or dirt. Do not use abrasive cleaners or liquids directly on the switch.
- If you notice any unusual behavior, such as flickering lights or intermittent operation, disconnect power and inspect the wiring connections for looseness.
7. Troubleshooting
If your cooler is not functioning correctly after switch installation, consider the following:
- No Power to Cooler: Check the circuit breaker or fuse for the cooler circuit. Ensure it is in the 'ON' position. Verify that the main power supply to the switch is active.
- Incorrect Functionality: Review the wiring diagram provided with the switch. Ensure all wires are connected to the correct terminals. Loose connections can cause intermittent operation or failure.
- Only 4 Positions Work: This is normal for single-speed evaporative cooler motors. The switch is designed to accommodate both single and multi-speed systems.
- Switch Feels Loose: Disconnect power and check the mounting screws securing the switch to the wall box. Tighten if necessary.
If issues persist after checking these points, consult a qualified electrician.
