2. Informații de siguranță
Vă rugăm să respectați următoarele măsuri de siguranță pentru a preveni vătămările corporale sau deteriorarea produsului.
- Deconectați întotdeauna sursa de alimentare înainte de a efectua orice operațiune de întreținere, instalare sau curățare.
- Asigurați-vă că răcitorul este așezat pe o suprafață stabilă și plană.
- 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.
- Nu folosiți răcitorul de lichid dacă cablul de alimentare sau ștecherul sunt deteriorate.
- Do not immerse the main chiller unit in water. The water pump is submersible, but the chiller unit is not.
- Acest aparat este destinat exclusiv utilizării în interior.
- A nu se lăsa la îndemâna copiilor.
- Use a Ground Fault Circuit Interrupter (GFCI) for all electrical connections to prevent electrical shock.

Figure 3: Recommended clearance for heat dissipation. This diagram illustrates the importance of maintaining at least 6 inches (15 cm) of space between the chiller and any walls or obstructions to ensure proper airflow and cooling efficiency.

4. Instrucțiuni de configurare
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.
- Prepare Connectors: 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.
- Conectați pompa de apă: Attach one end of the water pipe to the outlet of the submersible water pump. Secure it with a clamp dacă este necesar.
- 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.
- Asigurați-vă că toate conexiunile sunt sigure și etanșe pentru a preveni scurgerile.
- Pompa de scufundare: Place the submersible water pump into your aquarium or hydroponic reservoir. Ensure it is fully submerged and positioned to draw water effectively.
- Conexiune de alimentare: Plug the chiller's power cord into a GFCI-protected electrical outlet. Plug in the water pump's power cord.

5. Instrucțiuni de utilizare
The chiller features a digital control panel for temperature setting and calibration.
5.1. Pornire/Oprire
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: Apăsați tasta Set cheie. Folosește ▲ (sus) sau ▼ (down) arrow keys to adjust the desired shutdown temperature (e.g., 77°F). Press the Rst tasta de salvat.
- Set Starting Temperature (F1 Code): Apăsați lung pe Set cheie până la 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:
- Apăsați lung pe Set tasta de afișat F1. Apăsați tasta ▲ tasta de afișat F2. Presa Set din nou.
- Utilizați ▲ 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 pentru a reveni la afișajul temperaturii curente.
6. Întreținere
Întreținerea regulată asigură performanțe optime și prelungește durata de viață a răcitorului de lichid.
- Orificii de aer curat: 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.
- Inspectați furtunurile și conexiunile: 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.
- Calitatea apei: Maintain good water quality in your aquarium or hydroponic system to reduce the buildup of contaminants in the chiller's internal components.
