Safety Information
Please read all safety warnings and instructions carefully before operating the TECO TK500 chiller. Failure to follow these instructions may result in product damage, personal injury, or electric shock.
- Electrical Safety: Always disconnect the chiller from the power supply before performing any maintenance or cleaning. Ensure the power outlet is properly grounded and matches the voltage requirements of the unit. Do not operate the chiller with a damaged power cord or plug.
- Water Safety: Ensure all hose connections are secure to prevent leaks. Do not submerge the chiller unit in water. This appliance is not suitable for children under the age of 8 years old.
- Ventilation: The chiller requires adequate ventilation for proper operation and heat dissipation. Do not block the air intake or exhaust vents. Maintain sufficient clearance around the unit.
- Refrigerant: This unit uses R290 refrigerant. Do not attempt to service the refrigerant system yourself. Refer to qualified personnel for any refrigerant-related issues.

Setup and Installation
Follow these steps for proper installation of your TECO TK500 water chiller:
- Placement: Position the chiller in a well-ventilated area, ideally under a cabinet stand or externally, ensuring at least 6 inches of clearance around all sides for optimal airflow. The rotatable exhaust vent allows for flexible placement.
- Hose Connections: Attach the 5/8" barbed hose fittings to the inlet ("IN") and outlet ("OUT") ports on the back of the chiller. Secure them with the provided hose clamps.
- Water Flow: Connect the inlet hose from your aquarium's water pump (or sump return) to the chiller's "IN" port. Connect the outlet hose from the chiller's "OUT" port back to your aquarium or sump. Ensure your water pump provides a flow rate between 132-211 GPH (gallons per hour).
- Power Connection: Once all water connections are secure and checked for leaks, plug the chiller's power cord into a grounded electrical outlet.

- Power On/Off: Press the power button (usually combined with the down arrow) to turn the unit on or off.
- Setting Temperature: Press the "SET" button. The display will flash. Use the Up and Down arrow buttons to adjust the desired temperature. Press "SET" again to confirm. The chiller will maintain the water temperature within 1°F of your set point.
- Temperature Units: The digital thermostat allows you to switch between Fahrenheit (°F) and Celsius (°C). Refer to the full manual for specific button combinations to change units.
- Alerts: The unit can be configured to provide audible alerts for temperature deviations.
- WiFi Module (Optional): The TECO TK500 is compatible with the optional TECOnnect WiFi module, allowing for mobile app control and alerts. Consult the TECOnnect module's instructions for setup.
Maintenance
Regular maintenance ensures the efficiency and longevity of your TECO TK500 chiller.
- Air Filter Cleaning: The chiller features a magnetic front air filter. Regularly remove and clean the air filter to prevent dust and debris buildup, which can impede airflow and reduce cooling efficiency. Clean with warm water and mild soap, rinse thoroughly, and ensure it is completely dry before reinserting.
- Coil Cleaning: Periodically inspect the condenser coils for dust accumulation. Use a soft brush or vacuum cleaner with a brush attachment to gently remove any buildup.
- Hose and Connection Inspection: Regularly check all hoses and connections for signs of wear, kinks, or leaks. Replace any damaged components immediately.
- Water Flow: Ensure consistent water flow through the chiller. Reduced flow can impact performance. Clean your aquarium pump and plumbing as needed.

Troubleshooting
If you encounter issues with your TECO TK500 chiller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chiller not turning on | No power, tripped circuit breaker, faulty power cord. | Check power connection, reset circuit breaker, inspect power cord for damage. |
| Water not cooling sufficiently | Blocked air filter, insufficient water flow, ambient temperature too high, chiller undersized for tank. | Clean air filter, check water pump and hoses for obstructions, ensure adequate ventilation, verify chiller capacity for your tank size. |
| Excessive noise | Vibrations, fan obstruction, unit not level. | Ensure unit is on a stable, level surface. Check for any objects touching the fan or casing. |
| Water leaking | Loose hose connections, damaged hoses. | Tighten hose clamps, inspect hoses for cracks or punctures and replace if necessary. |
If the problem persists after attempting these solutions, please contact TECO customer support.
