2. Varnostne informacije
Prosimo, upoštevajte naslednje varnostne ukrepe, da preprečite poškodbe ali škodo na izdelku.
- Pred kakršnim koli vzdrževanjem, namestitvijo ali čiščenjem vedno izklopite napajanje.
- Poskrbite, da bo hladilnik postavljen na stabilno in ravno površino.
- Maintain at least 6 inches (15 cm) of clear space around the chiller for adequate heat dissipation. Blocking vents can lead to overheating and reduced performance.
- Do not operate the chiller if the power cord or plug is damaged.
- Do not immerse the main chiller unit in water. The water pump is submersible, but the chiller unit is not.
- Ta naprava je samo za uporabo v zaprtih prostorih.
- Hraniti izven dosega otrok.
- Use a Ground Fault Circuit Interrupter (GFCI) for all electrical connections to prevent electrical shock.

4. Navodila za nastavitev
Follow these steps for proper installation of your aquarium chiller.
- Positioning the Chiller: Place the chiller on a flat, stable surface near your aquarium or hydroponic system. Ensure there is at least 6 inches (15 cm) of clear space around all sides for optimal airflow and heat dissipation.
- Priprava konektorjev: Gather the provided connectors, including the white sealing washers.
- Install Inlet/Outlet Nozzles:
- Insert a white sealing washer onto each inlet/outlet nozzle.
- Place the pipe joint into the black nut cap.
- Tighten the black nuts onto the chiller's inlet and outlet ports.
- Priključite vodno črpalko: Attach one end of the water pipe to the outlet of the submersible water pump. Secure it with a clamp če je potrebno.
- Connect Chiller to System:
- Connect the other end of the water pipe from the pump to the chiller's inlet port.
- Connect a second water pipe from the chiller's outlet port back to your aquarium or hydroponic system.
- Prepričajte se, da so vse povezave varne in vodotesne, da preprečite puščanje.
- Potopna črpalka: Place the submersible water pump into your aquarium or hydroponic reservoir. Ensure it is fully submerged and positioned to draw water effectively.
- Napajalni priključek: Plug the chiller's power cord into a GFCI-protected electrical outlet. Plug in the water pump's power cord.

5. Navodila za uporabo
The chiller features a digital control panel for temperature setting and calibration.
5.1. Vklop/izklop
Locate the power switch on the back of the unit. Flip the switch to the 'ON' position to power on the chiller. The digital display will illuminate.

Figure 8: Power switch. This image shows the main power switch located on the rear panel of the chiller unit.
5.2. Temperature Setting (Assumed Target Temperature Range: 75-79°F)
The chiller will begin cooling after a 2-3 minute power-on delay. To adjust the target temperature:
- Set Shutdown Temperature: Pritisnite Set ključ. Uporabi ▲ (gor) oz ▼ (down) arrow keys to adjust the desired shutdown temperature (e.g., 77°F). Press the Rst ključ za shranjevanje.
- Set Starting Temperature (F1 Code): Dolgo pritisnite Set ključ do F1 code appears. Then, press the Set key again. Use the ▲ or ▼ arrow keys to adjust the temperature difference (e.g., to 4°F for a working range of 4°F).

Figure 9: Temperature setting and F2 calibration. This image provides a visual guide to setting the shutdown temperature and adjusting the F1 code for the working temperature range, as well as the F2 calibration process.
5.3. F2 Calibration Setting
If the chiller's displayed temperature does not match an external thermometer, you can calibrate it:
- Dolgo pritisnite Set tipka za prikaz F1. Pritisnite ▲ tipka za prikaz F2. Pritisnite Set znova.
- Uporabite ▲ or ▼ arrow keys to adjust the offset value (e.g., to 5 if the chiller reads 77°F and the actual temperature is 72°F, meaning a -5 adjustment is needed). Press Rst za vrnitev na prikaz trenutne temperature.
6. Vzdrževanje
Regular maintenance ensures optimal performance and extends the lifespan of your chiller.
- Čisti zračniki: Periodically check and clean the air intake and exhaust vents to prevent dust and debris buildup, which can impede heat dissipation. Use a soft brush or vacuum cleaner.
- Preverite cevi in priključke: Regularly check hoses and connections for any signs of leaks, kinks, or damage. Replace damaged components immediately.
- Clean Water Pump: Disconnect power to the pump and remove it from the water. Disassemble and clean the impeller and pump housing to remove any algae or debris that may affect water flow.
- Kakovost vode: Maintain good water quality in your aquarium or hydroponic system to reduce the buildup of contaminants in the chiller's internal components.
