3.3 Drainage Options
The Fridgemaster dehumidifier offers two drainage methods: manual bucket emptying or continuous drainage using the built-in pump.
3.3.1 Manual Drainage (Bucket)
The unit will collect condensed water in the internal water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate.
- Gently pull out the water tank from the front of the unit.
- Empty the collected water into a sink or drain.
- Slide the empty water tank back into the unit until it clicks into place. The unit will resume operation.
3.3.2 Continuous Drainage (Built-in Pump)
For continuous operation without needing to empty the bucket, use the built-in pump feature. A quick-connect water hose is included for this purpose.
- Locate the drain hose outlet on the back or side of the unit (refer to Figure 2.2).
- Connect one end of the provided quick-connect hose to the drain hose outlet. Ensure a secure connection.
- Route the other end of the hose to a suitable drain location, such as a sink, floor drain, or basement window. Ensure the hose is sloped downwards to allow for proper drainage and is not kinked.
- Activate the pump function on the control panel (refer to Section 4.2).
Note: The built-in pump can discharge water vertically up to a certain height (check specifications for exact height, typically 15 feet).
