Electronic Drain Valve Adjustment
The automatic drain valve has been pre-programmed at the
factory for your specific HGEN Series dryer. Programming is
based upon a minimum of 100 psi saturated inlet air pressure
and maximum energy efficiency. Generally no adjustment to
the timer is necessary.
If water is present downstream of the dryer,
always verify that and condensate drains installed upstream
of the dryer are draining properly before attempting to adjust
the timer settings.
1. For minimum inlet air pressures that fall between column
values the setting for the lower pressure is recommended.
(i.e. select the 100 psi column values for 124 psi inlet pres-
sure.)
2. Where the dryer is consistently operating at less than
maximum capacity, it may be possible to alter the timer set
points to minimize air loss. Discretionary adjustments to the
dryer should only be made on a hot, humid day when the
maximum expected air load is flowing through the dryer.
Failure to do so may prevent the condensate from draining
completely when operating under peak load conditions.

Assumes dryer operates at ISO 7183 (Option A2) conditions: 100°F inlet air
temperature, 100 psig operating pressure, 100°F ambient air temperature and
10°F air-cooled after-cooler approach temperature.

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 op-
erated. 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.
Energize Dryer: Turn disconnect switch to "ON" position.
4.
Green dryer ON/OFF switch will illuminate.
Energize dryer for 24 hours before refrigera-
tion compressor is started! Never use the disconnect switch
to shutdown the dryer for an extended period of time
(except for repair). Failure to follow these instructions may
result in a non-warrantable compressor failure.

5. Ensure adequate ventilation for air-cooled dryers.
6. On water-cooled models, before starting dryer, begin cool-
ing water flow.
To start dryer:
1. Turn the power switch to ON. The refrigerant compressor
will turn on.
Dryer must be energize 24 hours before
starting refrigeration compressor.
2. Allow the dryer to run 15 minutes. Confirm that the tem-
perature indicators are in the green zone.
3. SLOWLY pressurize the dryer. The outlet valves of the dryer
should be closed to prevent flow through the dryer.
4. SLOWLY open the dryer outlet valves permitting flow
through the dryer.
5. Confirm that condensate is discharging from the drain valve
by pressing the "Push-to Test" button.
6. Check drain valve timing. See Automatic Drain Valve section
for drain valve adjustment procedure.
7. Confirm that the inlet air temperature, pressure and airflow
to the dryer meet the specified requirements (see Engi-
neering Data section).
8. Confirm that the condensate lines from the drain valve
Off
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 equip-
ment failure and serious personal injury.
