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:
Apex unit nominal hp
15
20
25
RNC dryer model
RNC75
RNC100
RNC125
·
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 1ph-60Hz-115vac receptacle to plug in the
dyer power cord. Refer to the dryer serial number tag for the proper ampacity.
·
Starting and stopping the dryer -
o
Energize the receptacle - green power light will illuminate in the control panel.
o
Toggle ON/OFF switch to the ON position to start dryer operation. It is recommended
that the dryer be started 15min before the compressed air flow begins.
o
Do not stop or de-energize the dryer during the normal operational shift (e.g., 8 hrs) of
compressed air system.
o
The RNC dryer runs continuously when turned on. This is normal operation.
o
Toggle ON/OFF switch to the OFF position to stop dryer operation.
