Cooler and fan check (Fig.2)
The equipment altogether, and especially the compressor fan, cooler fan (21) and cooler (14), must
be kept clean to ensure efficient drying performance; vacuum or blow down the cooling fins and fans
with compressed air to remove any dust from the surface.
Jumper connections
It may be necessary to start the cabinet-mounted compressors outside of the cabinet for service
purposes. This means starting the compressor without the cabinet connector attached. To start the
compressor, a jumper must be installed in the electrical box.
