7.4 FILTRATION
It is important that a prefilter and an afterfilter be provided in your dryer installation.
Coalescing prefilters, located before the dryer, protect desiccant beds from contam-
ination by oil, entrained water, pipe scale, etc., thereby, extending the life of the
desiccant material. Locate prefilters as close to dryer as possible.
It is recommended that a mechanical separator be installed immediately preceding
the prefilter to remove the bulk liquid and entrained water.
Particulate afterfilters, located after the dryer, help eliminate the possibility of
desiccant dusting and carryover into the air system.
7.5 ELECTRICAL CONNECTION
Make all electrical connections to the dryer as shown on the wiring diagram. Care
must be taken in connecting the proper voltages.
Size field connection knock-out for the conduit fitting required by the NEC.
All dryers must have proper filtration. A .3 micron coalescing filter with automatic
drain & particulate after filter must be used as a minimum. Failure to provide
proper filtration for dryer will void warranty.
Dryer must be grounded with the full sized ground wire connected to an earth
ground.
Dryer must be fused according to NEC with the size fuse listed on the dryer
serial nameplate, or on specification sheet in technical manual.
