Frequently Asked Questions - PR581DH PRIMO
How to empty the water tank?
The tank is located at the front or side. Gently pull it out, empty it into a sink, and replace it, making sure it is properly engaged. The unit automatically stops when the tank is full.
Can I use a continuous drain hose?
Yes, the PR581DH model allows continuous drainage. Connect a hose (12 mm diameter) to the outlet at the back and direct it to a drain. Make sure the hose is not kinked or blocked.
Why won't my dehumidifier start?
Check that the unit is plugged in and the tank is correctly inserted. If the tank is full, the unit will not start. Wait 3 minutes after powering on for the compressor to restart.
How often should I clean the filter?
It is recommended to clean the filter every 15 days to maintain efficiency. Remove the filter, wash it with warm soapy water, rinse, and dry completely before replacing.
Does the dehumidifier freeze in winter?
The unit is equipped with an anti-freeze function. When the ambient temperature drops below 5°C, the compressor automatically stops to prevent ice formation on the coils.
What is the power consumption?
The rated power consumption is 250 W, which corresponds to about 0.25 kWh per hour of operation. With continuous use, expect about 6 kWh per day.
Can I use the unit in a bathroom?
Yes, but it must be placed on a stable surface and out of reach of water splashes. Do not use it in a room with extreme humidity (above 95% RH) continuously.
How to set the desired humidity level?
Use the 'Hygrostat' button to select the humidity level between 30% and 80%. The unit will automatically stop once the level is reached and restart when humidity increases.
The dehumidifier is noisy, is this normal?
Yes, the noise level is about 42 dB(A), which is comparable to a refrigerator noise. If the noise becomes abnormal (clicking, strong vibrations), check that the unit is level and the tank is properly in place.
Where can I find spare parts?
Spare parts (filter, tank, hose) are available from Primo after-sales service or on approved spare parts websites. Consult the manual for exact references.
