Operating Instructions

Automatic Defrost
The MalTec DH-2200 is equipped with an automatic defrost function. If frost builds up on the evaporator coils, the unit will automatically enter defrost mode to melt the ice. During this time, dehumidification may temporarily stop, and the fan may continue to run. This is normal operation.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your dehumidifier. Always unplug the unit before performing any maintenance.
Emptying the Water Tank
- When the water tank is full, the dehumidifier will automatically stop operating, and an indicator (if present) may light up.
- Gently pull out the water tank from the side of the unit.
- Carefully empty the collected water into a sink or drain.
- Rinse the tank with clean water periodically to prevent mold or mildew growth. Do not use harsh detergents.
- Reinsert the empty water tank firmly back into the unit until it clicks into place. The dehumidifier will resume operation.

- Remove the filter.
- Wash it with warm, soapy water, or vacuum it to remove dust.
- Allow the filter to dry completely before reinserting it.
