- Aqua Medic Titan 1500 Chiller Unit
- Power Cord
- Hose Connectors (e.g., for 16/22mm or 19/25mm hoses)
- User Manual (this document)
4. Setup and Installation
- Unpacking: Carefully remove the chiller from its packaging. Inspect for any signs of damage during transit. If damaged, do not operate and contact your supplier.
- Placement:
- Place the chiller on a stable, level surface.
- Ensure there is ample space (at least 20 cm or 8 inches) around all sides of the chiller, especially the air intake and exhaust vents, for proper air circulation.
- Avoid placing the chiller in direct sunlight or near heat-generating equipment.
- Water Connections:
- Identify the inlet and outlet ports on the chiller.
- Connect appropriate aquarium hoses (typically 16/22mm or 19/25mm, depending on your pump and system) to the chiller's hose connectors. Secure connections with hose clamps to prevent leaks.
- Connect the inlet hose from your aquarium's water pump (or sump return pump) to the chiller's inlet.
- Connect the outlet hose from the chiller to your aquarium or sump return.
- Ensure all connections are tight and leak-free.
- Electrical Connection:
- Before plugging in, ensure your water pump is running and water is flowing through the chiller. This prevents the chiller from running dry.
- Plug the chiller's power cord into a grounded electrical outlet.
5. Operating Instructions
- Power On: Once water flow is established, switch on the chiller using the power switch (refer to Figure 2). The digital display will illuminate.
- Setting Temperature:
- The display will show the current water temperature.
- Press the "SET" button (or equivalent, refer to your specific model's button layout) to enter temperature setting mode.
- Use the "UP" and "DOWN" arrows to adjust the desired temperature.
- Press "SET" again to confirm your selection. The chiller will now work to maintain the set temperature.
- Normal Operation: The chiller will automatically turn on when the water temperature rises above the set point and turn off once the desired temperature is reached. Allow some time for the chiller to stabilize the water temperature, especially during initial setup.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your chiller.
- Cleaning Air Filters/Coils: Periodically (e.g., monthly), check and clean the air intake filters and condenser coils. Dust and debris can accumulate, reducing cooling efficiency. Use a soft brush or vacuum cleaner to remove dust. Ensure the unit is unplugged before cleaning.
- Water Flow Check: Regularly inspect hoses and connections for kinks, blockages, or leaks. Ensure consistent water flow through the chiller.
- General Cleaning: Wipe the exterior of the chiller with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Long-Term Storage: If storing the chiller for an extended period, drain all water from the unit, clean it thoroughly, and store it in a dry, cool place.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chiller not turning on | No power, faulty power cord, tripped circuit breaker. | Check power connection, wall outlet, and circuit breaker. Ensure power switch is ON. |
| Chiller running but not cooling effectively | Blocked air vents, dirty coils, insufficient water flow, ambient temperature too high, chiller undersized. | Clean air filters and coils. Check water pump and hoses for blockages. Ensure adequate ventilation. Verify chiller capacity matches tank size. |
| Water leaking from connections | Loose hose clamps, damaged O-rings, cracked hose. | Tighten hose clamps. Inspect and replace O-rings or hoses if damaged. |
| Unusual noise from chiller | Vibrations, fan obstruction, compressor issue. | Ensure chiller is on a level surface. Check for foreign objects near the fan. If noise persists, contact support. |
If the problem persists after attempting these solutions, please contact Aqua Medic customer support.
