2.2 Col·locació
The pump is designed for under A/C unit mounting. Consider the maximum suction height of 10 ft (3 m) and maximum head of 65.6 ft (20 m) when determining the pump's location relative to the condensate source and discharge point.
2.3 Discharge Line Connection
Connect the provided 1/4" I.D. (6.25 mm) discharge tube to the pump's outlet. Ensure the tube is routed without kinks or sharp bends to allow for unobstructed condensate flow.
3. Instruccions de funcionament
The Gobi II pump operates automatically based on its digital water sensor. Once properly installed and powered, it will activate to remove condensate when the water level in the reservoir reaches a predetermined point.
- Funcionament automàtic: The pump's digital sensor detects condensate levels and initiates pumping cycles as needed.
- User-Configurable Flow: The pump features user-configurable flow settings to optimize performance for various AC unit capacities. Refer to the specific configuration guide for detailed instructions on adjusting flow settings.
- Funcionament silenciós: The pump is designed for quiet operation, typically producing 20dBA at 3 ft (1 m) distance.
4. Manteniment
Regular maintenance ensures the longevity and optimal performance of your Gobi II condensate pump.
- Neteja del sensor: Periodically inspect and gently clean the digital water sensor to prevent buildup that could affect its accuracy. Disconnect power before cleaning.
- Reservoir Inspection: Check the pump's reservoir for any debris or sludge accumulation. Clean as necessary to maintain clear operation.
- Discharge Line Check: Ensure the discharge line remains clear of obstructions and kinks. Verify that water is flowing freely from the discharge point.
5. Solució De Problemes
If you encounter issues with your Gobi II pump, refer to the following troubleshooting guide:
| Problema | Causa possible | Solució |
|---|---|---|
| La bomba no funciona | No power; Sensor malfunction; Motor failure | Check power supply and connections; Clean sensor; Contact qualified technician if motor is suspected to be faulty. |
