The timer function will not be retained and you need to reset it.
Temperature Protection Function
When the room temperature is higher than 113°F, the dehumidifier will automatically enter into HIGH-TEMPERATURE PROTECTION SYSTEM where the LCD screen shows “ ” and the compressor stops working.
When the room temperature is lower than 40°F, the dehumidifier will automatically enter into LOW-TEMPERATURE PROTECTION SYSTEM where the LCD screen shows “ ” and the dehumidifier stops working.

Drainage

Pump Drainage
During operation, the dehumidifier will automatically pump the water out via the drain hose when the pump reservoir is full. No need manual intervention.
Before turning on the dehumidifier, make sure the hose has been connected to the drain outlet properly. NOTE:
Place the unattached end n a sink, drain, bucket or outdoors – anywhere that water can drain out safely. ( Ensure there are no kinks or other obstructions that will stop the water to flow.)
If you use a bucket or other container for water collection, check it regularly to prevent overflows. The drain hose for the water pump can drain up to 15ft vertically. More than 15ft may cause water flow back to the pump and result in water leakage.
Continuous Drainage NOTE:

1. Please make sure the connections are tightly connected to avoid water leakage.
2. The hose should be lower than the drain outlet to avoid backflow.
3. The hose cannot be distorted or has substantial turning.
