A year or so should be a comprehensive and thorough cleaning of the heat pump dryer, you can use a screwdriver gently pry out one side of the panel, and then use a vacuum cleaner to remove the surrounding dust. Be careful to avoid machine parts.

Then wash the condenser and evaporator with gentle water flow, and brush the dust of the evaporator and condenser gently with a brush. In other places, carefully wipe the dust with a slightly wet towel. Keep in mind that water does not touch the place where electricity is connected, so as to avoid unnecessary accidents and damage. For the cleaning of condenser tubes, high-pressure water jet of appropriate pressure level can be selected for cleaning, or chemical cleaning can be carried out according to tube material and scale sample analysis. The chemical cleaning process is as follows:

Site investigation -- preparation before entering the site (determine pump station model and supporting pipeline according to condenser parameters; determine appropriate cleaning medium after scale sample analysis and small-scale test) --- handling of entry procedures -- cleaning of high-pressure water dredging and flow pipe slime -- temporary system installation -- chemical cleaning -- high-pressure water cleaning -- Acceptance -- system recovery -- leaving the site
