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 power
25hp
30hp
18kW
22kW
Dryer model
RNC125
RNC150
RES 120
RES 140
·
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.
