START-UP/OPERATION
Follow the procedure below to start your dryer. Failure
to follow the prescribed start-up procedure will invalidate
the warranty. If problems arise during start-up, call your
distributor.
Refer to Serial Number Tag for dryer operating
capacity. Do not exceed recommended capacity.
Drain connections must be made before the dryer can be
operated. The dryers are fully automatic and require no
auxiliary controls.
1. Turn the dryer ON/OFF switch to OFF.
2. Check that the main electrical supply voltage matches
the voltage specified on the dryer data plate.
3. Check proper connection and support of compressed air
lines to the dryer; check bypass valve system, if installed.
4. SLOWLY pressurize the dryer. The outlet valves of the
dryer should be closed to prevent flow through the
dryer.
5. Turn on the main electrical power to the dryer.
6. Ensure adequate ventilation for air-cooled dryers.
To start dryer:
1. Turn the power switch to ON. The refrigerant compressor
will turn on.
2. Allow the dryer to run 15 minutes. Confirm that the
temperature indicators are in the green zone.
3. SLOWLY open the dryer outlet valves permitting flow
through the dryer.
4. Confirm that condensate is discharging from the drain
valve by pressing the "TEST" button.
5. Check drain valve timing. See AUTOMATIC DRAIN VALVE
section for drain valve adjustment procedure.
6. Confirm that the inlet air temperature, pressure and
airflow to the dryer meet the specified requirements (see
Engineering Data section).
7. Confirm that the condensate lines from the drain valve
discharge into a collection tank or an environmentally-
approved disposal system.
The dryer is designed to run continuously. Let the dryer run
even when the demand for compressed air is interrupted;
the dryer will not freeze up.
SHUTDOWN
When the dryer must be shutdown for maintenance or other
reasons, use the following procedure.
If electrical repairs must be made:
1. Turn off the power switch.
2. Disconnect the main power supply.
3. Lock out and tag the power supply in accordance with
OSHA requirements.
If mechanical repairs are to be made or service is performed,
vent the internal pressure of the dryer to atmospheric
pressure. Restart the dryer according to the start-up
instructions.
Disconnect power supply and depressurize
dryer before servicing. Dismantling or working on any
component of the compressed air system under pressure
may cause equipment failure and serious personal injury.
MAINTENANCE
The dryers require little maintenance for satisfactory
operation. Good dryer performance can be expected if the
following routine maintenance steps are taken.
Dismantling or working on any component
of the compressed air system under pressure may cause
equipment failure and serious personal injury. Before
dismantling any part of the dryer or compressed air system,
completely vent the internal pressure to the atmosphere.
General
For continued good performance of your refrigerated dryer,
all refrigeration system maintenance should be performed by
a competent refrigeration mechanic.
NOTE: Before corrective maintenance is done during the
warranty period, call your local distributor and proceed
according to instructions. Refer to the warranty for limits of
your coverage.
Daily Maintenance
Check the operation of the automatic drain valve at least
once daily. See the Field Service Guide for remedies to drain
valve malfunctions. See the AUTOMATIC DRAIN VALVE section
for drain valve adjustment.
