2. Enfòmasyon sou Sekirite
Tanpri obsève prekosyon sekirite sa yo pou evite blesi oswa domaj nan pwodwi a.
- Always disconnect the power supply before performing any maintenance, installation, or cleaning.
- 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.
- Aparèy sa a se pou itilize andedan kay la sèlman.
- Kenbe soti nan atenn timoun yo.
- Use a Ground Fault Circuit Interrupter (GFCI) for all electrical connections to prevent electrical shock.

4. Enstriksyon Enstalasyon
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.
- Connect Water Pump: Attach one end of the water pipe to the outlet of the submersible water pump. Secure it with a clamp si sa nesesè.
- 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.
- Asire w tout koneksyon yo byen fèm epi yo pa kite dlo pase pou anpeche flit.
- Ponp plonje: Place the submersible water pump into your aquarium or hydroponic reservoir. Ensure it is fully submerged and positioned to draw water effectively.
- Koneksyon pouvwa: Plug the chiller's power cord into a GFCI-protected electrical outlet. Plug in the water pump's power cord.

5. Operasyon Enstriksyon
The chiller features a digital control panel for temperature setting and calibration.
5.1. Power On/Off
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: Peze a Mete kle. Sèvi ak la ▲ (moute) oswa ▼ (down) arrow keys to adjust the desired shutdown temperature (e.g., 77°F). Press the Premye kle pou konsève pou.
- Set Starting Temperature (F1 Code): Long peze la Mete kle jiska la F1 code appears. Then, press the Mete 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:
- Long peze la Mete kle pou montre F1. Peze a ▲ kle pou montre F2. Peze Mete ankò.
- Sèvi ak la ▲ 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 Premye pou retounen nan ekspozisyon tanperati aktyèl la.
6. Antretyen
Regular maintenance ensures optimal performance and extends the lifespan of your chiller.
- Vant lè pwòp: 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.
- Enspekte tiyo ak koneksyon yo: 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.
- Kalite dlo: Maintain good water quality in your aquarium or hydroponic system to reduce the buildup of contaminants in the chiller's internal components.
