5.2 Drainage Options

The Sandidry 55C offers two methods for continuous drainage:

5.2.1 Gravity Drainage

• Connect the included 6.5 ft gravity drain hose to the drain outlet on the unit.
• Ensure the hose is sloped downwards to a floor drain or suitable receptacle, allowing water to flow out by gravity.
• Do not allow the hose to kink or rise above the unit's drain outlet.

5.2.2 Pump Drainage

• Connect the included 19.6 ft pump drain hose to the pump outlet.
• The built-in condensate pump allows water to be directed upwards (up to 19.6 feet) or to a distant drain, such as a sink, outside a window, or a dedicated condensate pump drain.
• Ensure the pump hose is securely connected and routed to prevent leaks.

6. Operation

The control panel provides easy access to all functions.

Figure 6.1: Detailed view of the dehumidifier's control panel.

6.1 Basic Controls

• ON/OFF Button: Press to turn the unit on or off.
• SET Button: Use to adjust the desired humidity level. The display will show the set humidity percentage.
• DRAIN Button: Activates or deactivates the pump drainage function.
• GPP MODE Button: Toggles between different operating modes (e.g., General Purpose, Performance). Refer to the display for current mode.

6.2 Operating Modes

• Continuous Mode: The unit will operate continuously regardless of the humidity level until manually turned off or the GPP mode is selected.
• Humidity Setting Mode: The unit will operate until the ambient humidity reaches the set target level, then cycle on and off to maintain it.
• GPP Mode: (General Purpose/Performance Mode) This mode optimizes the unit's operation for specific conditions. Consult the display for details on its function.

6.3 Auto-Defrost

The unit is equipped with an automatic defrost function. If frost builds up on the evaporator coils, the unit will temporarily stop dehumidifying and run the fan to melt the frost. This is a normal operation and ensures efficient performance in cooler environments. Dehumidification will resume once the coils are clear.

7. Maintenance

Regular maintenance ensures the longevity and efficiency of your dehumidifier.

7.1 MERV-1 Filter Cleaning/Replacement

• The MERV-1 filter should be checked and cleaned every 3-6 months, or more frequently depending on air quality.
• To clean, remove the filter and wash it with warm, soapy water. Rinse thoroughly and allow it to air dry completely before reinserting.
• Replace the filter if it is damaged or cannot be cleaned effectively.

7.2 Unit Cleaning

• Always unplug the unit before cleaning.
• Wipe the exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Ensure air inlets and outlets are free from dust and debris.

7.3 Storage

• If storing the unit for an extended period, ensure all water is drained from the reservoir and hoses.
