- Ensure there is at least 20 cm (8 inches) of space around the air inlet and outlet for optimal airflow.
- Avoid placing the unit near heat sources or in direct sunlight.
4.2 Power Connection
Plug the power cord into a grounded electrical outlet. Ensure the outlet meets the electrical requirements of the unit (115V/60Hz).
4.3 Drainage Setup
The unit offers two drainage options: gravity drainage and pump drainage.
Gravity Drainage:
For continuous gravity drainage, connect the provided drain hose to the gravity drain port on the unit. Ensure the hose is sloped downwards to a suitable drain or container, allowing water to flow out naturally. Do not allow the hose to kink or be elevated above the drain port.
Pump Drainage:
For pump drainage, connect the provided drain hose to the pump drain port. The integrated pump allows water to be discharged vertically up to 5 meters or horizontally over longer distances. Ensure the hose is securely connected and directed to a suitable drainage point.
The integrated drain pump allows for flexible water discharge, including a 5-meter drain hose for continuous drainage and the ability to pump water vertically up to 5 meters.
