2. 안전 정보
부상이나 제품 손상을 방지하기 위해 다음 안전 수칙을 준수해 주십시오.
- 유지보수, 설치 또는 청소를 하기 전에 항상 전원을 차단하십시오.
- Ensure the chiller is placed on a stable, level surface.
- 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.
- 이 제품은 실내에서만 사용하세요.
- 어린이의 손이 닿지 않는 곳에 보관하세요.
- Use a Ground Fault Circuit Interrupter (GFCI) for all electrical connections to prevent electrical shock.

4. 설정 지침
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.
- 워터펌프 연결: Attach one end of the water pipe to the outlet of the submersible water pump. Secure it with a clamp 필요한 경우.
- 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.
- 모든 연결 부분이 안전하고 방수 처리되어 누수가 발생하지 않도록 하세요.
- 수중 펌프: Place the submersible water pump into your aquarium or hydroponic reservoir. Ensure it is fully submerged and positioned to draw water effectively.
- 전원 연결: Plug the chiller's power cord into a GFCI-protected electrical outlet. Plug in the water pump's power cord.

5. 사용 설명서
The chiller features a digital control panel for temperature setting and calibration.
5.1. 전원 켜기/끄기
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: 를 누르세요 세트 열쇠. 사용 ▲ (위로) 또는 ▼ (down) arrow keys to adjust the desired shutdown temperature (e.g., 77°F). Press the RST 저장하는 키입니다.
- Set Starting Temperature (F1 Code): 길게 누르세요 세트 키까지 F1 code appears. Then, press the 세트 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:
- 길게 누르세요 세트 표시 할 키 F1. 를 누르세요 ▲ 표시 할 키 F2. 누르다 세트 다시.
- 사용하세요 ▲ 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 현재 온도 표시로 돌아갑니다.
6. 유지관리
정기적인 유지보수는 최적의 성능을 보장하고 냉각기의 수명을 연장합니다.
- 깨끗한 공기 통풍구: 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.
- 호스 및 연결부 검사: 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.
- 물의 질: Maintain good water quality in your aquarium or hydroponic system to reduce the buildup of contaminants in the chiller's internal components.
