- Avoid placing the unit near heat sources, in direct sunlight, or in areas exposed to freezing temperatures.
- Power Connection: Plug the power cord into a grounded electrical outlet. Ensure the voltage matches the specifications of the unit.
- Continuous Drainage (Optional): If you prefer continuous drainage over manual tank emptying, connect a standard garden hose (not included) to the continuous drain outlet at the back of the unit. Ensure the hose is sloped downwards to allow gravity drainage into a suitable floor drain or larger container.

Operating Instructions
