OPERATION
6. PRODUCT
OPERATION
Proper dryer operation depends on the compressor activity and does not require any operation. The pressure
vessel does not need to be drained as the compressed air into the air tank is already dried.
The working pressure settings for the pressure switch set by the manufacturer cannot be changed. Compressor
operation at lower working pressures than the switching pressure is evidence that the compressor is overloaded
(high air consumption) caused by an appliance, a failed seal in the air line, compressor problem or dryer.
Before connecting the dryer to the air tank used on a compressor without a dryer, the internal surface of the air
tank must be properly cleaned and all condensed liquids must be completely removed. The electrical portion of
the dryer is then to be connected to the compressor following the electrical schematic pursuant to valid
regulations.
