It is critical to refer to the vendor-supplied instruction manual, included with the refrigerated dryer, for full
details on the installation, operation and maintenance of this optional device. When the dryer is part of
the Total System, the following are some of the critical items to keep in mind:

Dryer models corresponding to compressor package models:

Installation - Package must installed in a location with an ambient temperature range of 40ºF to
110ºF (3ºC to 43ºC). Consult Gardner Denver for operation outside this range.

Discharge service pipe - The discharge service line connection is provided at the outlet of the
bypass valve assembly. A hand operated valve, (air service valve) and a separate (swing-type)
check valve must be installed between the unit and the customer's air system. If a fast operating
valve such as a ball valve is used, it must be closed slowly to give the intake valve time to shut
and keep the discharge pressure from spiking.

Electrical power connections - Provide a grounded 1 phase, 60Hz, 115VAC receptacle to plug in
the dryer power cord. Refer to the dryer serial number tag for the proper ampacity.

Starting and stopping the dryer – Each dryer version has its own starting controls. Refer to the
vendor-supplied instruction manual included with the refrigerated dryer for full details of the
start/stop procedures.
GENERAL PURPOSE FILTER – All XGNC dryers have the option of including an in-line general purpose
air filter. All service intervals and operational details are defined in the vendor-supplied instruction manual
included with the filter.
