3. Setup and Installation
3.1 Unpacking
- Carefully remove the dehumidifier and all accessories from the packaging.
- Verify that all included components are present: Dehumidifier, Gravity Drain Hose, Pump Drain Hose, User's Guide.
- Inspect the unit for any shipping damage. If damage is found, contact customer support immediately.
3.2 Placement
For optimal performance, place the dehumidifier in a central location within the area requiring dehumidification. Ensure adequate airflow around the unit.

3.3 Drainage Options
The Shield 85P offers two methods for continuous water drainage:

Image: Diagram showing the two drainage methods: gravity drainage with a 6.5 ft hose and pump drainage with a 19.6 ft hose, indicating drain height capabilities.
- Gravity Drainage: Connect the included 6.5 ft drainage hose to the gravity drain port and direct it to a floor drain. Ensure the hose is sloped downwards to allow water to flow by gravity.
- Pump Drainage: For situations where a floor drain is not available or water needs to be directed upwards, use the built-in condensate pump. Connect the included 19.6 ft pump drain hose to the pump outlet. The pump can lift water up to 19.6 feet. Ensure the rubber stopper is used to plug the gravity drain hole when using pump drainage.
3.4 Power Connection
Plug the dehumidifier into a grounded electrical outlet. Ensure the voltage matches the unit's requirements.
4. Operating Instructions
4.1 Control Panel
The dehumidifier features a smart LCD display for easy operation and monitoring.

- Humidity Setting: Adjust the desired humidity level using the control buttons. The unit will operate until the set humidity is reached.
- Continuous Mode: For maximum dehumidification, select continuous mode. The unit will run constantly regardless of humidity levels.
- GPP Mode: Grains Per Pound (GPP) mode accurately measures the humidity level by calculating the number of grains of moisture per pound of air, providing precise readings for effective moisture removal.
- Coil Temperature Display: Shows the current temperature of the evaporator coils.
- Defrost Display: Indicates when the unit is in defrost cycle.
- Troubleshooting Interface: Provides error codes or indicators for operational issues.
- Drainage Mode Switch: Allows selection between gravity and pump drainage.

4.2 Automatic Defrost Function
The unit is equipped with an automatic defrost function. If frost builds up on the evaporator coils, the unit will temporarily stop dehumidifying and enter a defrost cycle. During this cycle, moisture removal may decrease until the coils are clear and the unit resumes normal operation.

4.3 Memory Start
In the event of a power outage, the unit will automatically restart with the last saved settings once power is restored.
4.4 Optional Remote Control
An optional remote control (purchased separately) can be used to adjust settings from a distance, enhancing convenience.

5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your dehumidifier.
5.1 MERV-1 Filter Maintenance
The unit is equipped with a MERV-1 filter to protect internal components from dust and particles. Regular cleaning and replacement are essential.
- Access: The MERV-1 filter is easily accessible for cleaning.
- Cleaning: The filter can be washed. It is recommended to replace the filter after two washes or every 3 months, whichever comes first.
- Replacement: Optional replacement MERV-1 filters are available.

5.2 General Cleaning
- Wipe the exterior of the unit with a soft, damp cloth.
- Do not use abrasive cleaners or solvents.
- Ensure the unit is unplugged before cleaning.
6. Troubleshooting
If you encounter issues with your dehumidifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on. | No power, power cord unplugged, circuit breaker tripped. | Check power connection, ensure outlet is functional, reset circuit breaker. |
| Unit is running but not dehumidifying. | Air filter clogged, room temperature too low, humidity setting too high, unit in defrost mode. | Clean or replace air filter, ensure room temperature is above 41°F (5°C), lower humidity setting, wait for defrost cycle to complete. |
| Water is not draining. | Drain hose kinked or blocked, pump malfunction (if using pump drainage), gravity drain not sloped correctly. | Check and clear drain hose, ensure proper slope for gravity drainage. If using pump, verify pump operation and ensure it restarts after power interruptions. |
| Unit is noisy. | Unit not level, air filter clogged, fan obstruction. | Ensure unit is on a level surface, clean air filter, check for obstructions around fan. |
If the problem persists after attempting these solutions, please contact ARGENDON customer support.
