1.2 Power Connection

Connect the power cord to a grounded electrical outlet. Ensure the voltage matches the specifications listed on the unit's rating label.

1.3 Condensate Drainage

The WDH-930EEW offers two drainage options:

1. Water Tank: The unit collects condensed water in a removable 5.5-liter water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Empty the tank as needed.
2. Continuous Drainage: For extended operation without manual emptying, connect the included drainage hose to the continuous drainage port. Route the hose to a suitable drain, ensuring it is sloped downwards to allow gravity to drain the water.
