This manual contains information and recommendations for installing, operating, and servicing
the
Pioneer R and ADR Series Dryers,
as well as
Mr. Goodaire and Mr. Goodaire Plus Series.
Pioneer systems are designed and manufactured to the highest standards of quality. The self-contained
units have been tested and inspected before shipment from the factory. Information in this manual is in
accord with the data applicable to standard equipment at the time of printing (non-standard changes may
not be included). The manufacturer reserves the right to make changes without notice and without
incurring obligation. The customer should read this manual carefully before locating and installing the
equipment.
Receiving and Inspection
After removing all packaging, examine the dryer for any external and internal damage. It is the
customer’s responsibility to notify the transportation agency of any damages immediately. Check the
nameplate to ensure proper power supply. Inspect all pipe and tubing. Vibration during shipping may
loosen connections. Standard refrigerated dryers are charged with refrigerant, operated, and tested
before leaving the factory. Units are ready to run after proper servicing.
Location Recommendations
Pioneer R and ADR Series Dryers
are designed for installation in a protected area that is clean,
dry, and has and ambient temperature range of 50 to 100
o
F (10 to 37
o
C). For installation in other
temperatures consult factory. Consider heat rejection when locating the unit. Position the unit to permit
free circulation of cooling air for the condenser. See Table 1 for safe distance placement.

Installation Recommendations
A refrigerated compressed air dryer is normally installed downstream of the receiver tank. A
compressed air line should be connected from the receiver tank outlet to the air dryer inlet. The outlet of
the dryer is then piped into the pneumatic distribution system. A bypass should always be installed to
permit operation of the compressed air system during dryer maintenance and servicing. See installation
schematic in Figure 1. Air in/out and bypassing piping should be equal or larger than the in/out sizes
provided on the dryer.
In the case of water cooled systems, make water connections to the dryer. Make sure water piping is
large enough to handle the flow requirements. The factory recommends making the pipe size equal to or
larger than the water connections on the dryer.
