2.8 Storage and Transportation
The Quest PowerDry 385D Pro can be transported and stored in either upright or horizontal positions.
There is a storage compartment under the top cover of your dehumidifier. This compartment is large enough to store
reactivation collars, power cords, filter (as used), as well as additional small items that you may require on your job
site.
3 Maintenance
3.1 Air Filter Replacement
The Quest PowerDry 385D Pro is equipped with two pleated
fabric air filters that must be checked regularly.
Process air stream filter:
This 16”x20”x2” filter is located in the top of your PowerDry
385D Pro underneath the top cover. The stock filter supplied
carries a MERV-11 filtration efficiency rating. This filter prevents
loading the desiccant wheel with foreign matter.
Reactivation air stream filter:
This 12”x12 x1” filter is located in the bottom of your PowerDry
385D Pro. To change the reactivation air filter, lay the PowerDry
385D Pro down in a horizontal position. The filter access slot is located on the bottom of the machine (Fig. 4). Open
retainment clip, remove old filter, and replace with fresh filter.
The stock filter supplied carries a MERV-7 filtration efficiency rating. This filtration prevents plugging the heater or
loading the desiccant wheel with foreign matter.
Operating the unit with a dirty filter will reduce the dehumidifier’s capacity and efficiency and may cause the heater
coil to cut out on thermal overload.
The filter can generally be vacuumed clean several times before needing replacement. Replacement filters can be
ordered from the factory or purchased locally if available.
DO NOT operate the unit without the filters or with less
effective filters as the desiccant wheel inside the unit will become clogged and require disassembly to clean.
