2. Sikkerhedsoplysninger
Læs alle sikkerhedsinstruktioner omhyggeligt inden installation og betjening. Manglende overholdelse af disse instruktioner kan resultere i elektrisk stød, brand eller alvorlig personskade.
- Afbryd altid strømmen til klimaanlægget og pumpen, før du udfører installation, vedligeholdelse eller fejlfinding.
- Installation must be performed by a qualified technician in accordance with all local and national electrical and plumbing codes.
- Sørg for, at pumpen er installeret et sted, hvor den er beskyttet mod direkte vandsprøjt og ekstreme temperaturer.
- Do not operate the pump with damaged cables or if it has been dropped or damaged.
- This pump is designed for condensate water only. Do not use it for other liquids.
- Hold børn og uautoriserede personer væk fra installationsområdet.

4. Opsætning og installation
The GOBI II pump is designed for direct mounting under the air conditioner unit. Follow these steps for proper installation:
- Montering: Secure the pump's wall back plate (component 9 in Figure 3.1) to a stable surface directly beneath the air conditioning unit using the provided screws and screw anchors. Ensure it is level.
- Pump Body Installation: Slide the pump body (component 1 in Figure 3.1) onto the mounted back plate until it clicks securely into place.
- Condensate Inlet Connection: Connect the condensate drain line from the air conditioning unit to the pump's inlet. Ensure a tight, leak-free connection.
- Tilslutning af udløbsledning: Connect the 1/4" discharge tube from the pump's outlet to your desired drain point. Install the provided anti-siphon device in the discharge line to prevent backflow and ensure proper pump operation. Ensure the discharge line rises vertically for at least 6 inches before running horizontally or downwards.
- Elektrisk tilslutning: Connect the power cable to the pump and then to a suitable power supply (100-240 VAC, 50/60 Hz). Ensure all electrical connections are secure and comply with local electrical codes.
- Alarm Cable Connection (Optional but Recommended): Connect the alarm cable to the pump's alarm relay terminals and integrate it with your HVAC system's alarm circuit if desired. The alarm relay is interchangeable (NO or NC) and rated for 250VAC, 6.3A or 28VDC, 6.3A.
- Test: Once all connections are made, restore power to the system. Pour a small amount of water into the air conditioner's drain pan to verify the pump activates and discharges water correctly. Check for any leaks.
5. Betjeningsvejledning
The GOBI II condensate pump operates automatically based on the water level detected by its digital sensor. It will activate when condensate accumulates and shut off once the water is cleared.
5.1. Digital Sensor and Flow Control:
The integrated digital sensor (component 4 in Figure 3.1) precisely monitors the water level, ensuring the pump activates only when necessary. The pump's demand-oriented control adjusts the pumping capacity as needed, optimizing efficiency and minimizing noise.
5.2. Diagnostic LEDs:
The pump features a diagnostic LED (component 8 in Figure 3.1) to indicate its operational status.
Figure 5.1: Diagnostic LED indicators.
- Grøn LED: Indicates normal operation. The pump is powered and functioning correctly.
- Rød LED: Indicates an error or alarm condition. Refer to the Troubleshooting section for possible causes.
6. Vedligeholdelse
Regular maintenance ensures the longevity and optimal performance of your GOBI II pump.
- Månedlig kontrol: Visually inspect the pump, inlet, and discharge lines for any blockages, kinks, or leaks. Ensure the pump housing is clean.
- Årlig rengøring: Disconnect power to the pump and the AC unit. Carefully remove the pump body from the wall back plate. Clean the water tray (component 5 in Figure 3.1) and the digital sensor (component 4) to remove any sludge, mold, or debris. A soft brush and mild detergent can be used. Rinse thoroughly with clean water.
- Filterudskiftning: The pump includes a replaceable filter (component 3 in Figure 3.1). Check its condition during annual cleaning and replace if it appears clogged or damaged.
- Genmontering: After cleaning, reassemble all components, ensuring they are securely in place. Restore power and test the pump's operation.
