INSTALLATION AND INSPECTION
A.
Inspection
Note: All piping and electrical connections should be checked to insure they have
maintained their integrity during shipping and installation.
All dryers are tested and inspected at the factory prior to shipping. Inspect the
dryer carefully upon arrival and note any damage on the freight bill. Uncrate and
inspect for concealed damage. File claims with the carrier immediately and notify
PSB service department.
B.
Dryer Location
Locate the dryer outdoors or in a well ventilated area and readily accessible for
maintenance. The dryer should have minimum 36" clearance on all sides. The
area should be clean, well lit and have a level, vibration free foundation. For
standard applications, ambient temperatures should range between 35°F and
100°F.
range.
C.
Filtration
IMPORTANT! Desiccant dryers are designed to remove water VAPOR only!
The inlet gas to be dried must pass through a Coalescing Pre-filter to remove
entrained condensate and oil to prevent fouling of the desiccant.
condensate entering the bed will lead to overloading of the dryer, poor dew point
performance, and rapid deterioration of the desiccant. Oil entering the desiccant
bed may permanently reduce the capacity of the desiccant. A Particulate After-
filter should be provided to prevent desiccant dust from traveling down stream.
Desiccant dust may cause contamination and excessive wear to equipment.
Differential pressure indicators are installed on filters for monitoring of elements.
