INSTALLATION
Ambient Air Temperature
Locate the dryer indoors where the ambient air temperature
will be between 40°F (4°C) and 110°F (43°C). Intermittent op-
eration at ambient temperatures up to 113°F (45°C) will not
damage the dryer but may result in a higher dew point or dryer
shutdown due to high refrigerant discharge pressure (see Field
Service Guide).
Do not operate dryers at ambient air temperatures below 40°F
(4°C). Such operation may result in low suction pressure, caus-
ing freeze-up.
Location and Clearance
Mount the dryer on a level solid surface. Holes are provided in
the dryer base to permanently mount the dryer to the floor. If
the base vibrates, bolt the unit down using vibration dampeners.
Allow at least 36 inches (914 mm) clearance on the sides and
the front of the dryer for cooling airflow and for service access.
System Arrangement
Liquid water in the inlet air will adversely affect the performance
of the dryer. Install the dryer downstream of an aftercooler or
separator so that the temperature of the dryer inlet air does
not exceed 120°F (49°C) and the inlet air does not contain any
liquid water.
If the compressed airflow is relatively constant and does not
exceed the dryer flow rating, it is recommended that the dryer
be located downstream of the receiver tank. If the nature of the
application is such that the air demand regularly exceeds the
dryer flow rating, it is recommended that the dryer be located
upstream of the receiver.
For safety and convenience, install inlet and outlet shutoff valves
and depressurization valves. These valves allow the dryer to be
isolated and depressurized for servicing. Bypass piping may
be installed around the dryer for uninterrupted airflow when
the dryer is serviced. If the compressed air operation cannot
tolerate undried air for short periods, install a second dryer in
the bypass line.
Compressed air systems commonly require filters to remove
compressor oils, particulates, condensed liquids and other
contaminants. When an oil-removal filter is used, it should be
installed downstream of the refrigerated dryer. At this location,
the life of the replaceable filter element is prolonged since
some of the entrained oil is removed by the dryer and drained
through the separator.
Piping and Connections
Piping must be furnished by the user unless otherwise speci-
fied. Connections and fittings must be rated for the maximum
operating pressure given on the dryer data plate and must be
in accordance with applicable codes. Support all piping; do not
allow the weight of any piping to stress the dryer or filter con-
nections. Piping should be at least the size of the inlet and outlet
connections to minimize pressure drop in the air system. See
Engineering Data section for dryer inlet and outlet connections
1. Air Inlet - Connect compressed air line from air source to
air inlet.
Refer to Serial Number Tag for maximum working
pressure. Do not exceed dryer's Maximum Working Pressure.
NOTE: Install air dryer in air system at highest pressure possible
(e.g. before pressure reducing valves).
NOTE: Install dryer at coolest compressed air temperature
possible. Maximum inlet compressed air temperature: 120°F
(49°C). If inlet air exceeds this temperature, precool the air with
an aftercooler.
2. Air Outlet - Connect air outlet to downstream air lines.
3. Bypass Piping - If servicing the dryer with interrupting the
air supply is desired, piping should include inlet and outlet
valves and an air bypass valve.
4. Water-cooled models - cooling water inlet and outlet.
a) Connect cooling water supply to cooling water inlet.
b) Connect cooling water return line to cooling water
outlet connection.
NOTE: Strainer and water regulating valve are supplied on water-
cooled models. Also, it is recommended to add water inlet/
outlet temperature and pressure gauges to the water piping.
Removing Condensate
Condensate must be drained from the dryer to prevent re-
entrainment. The dryers are equipped with automatic drain
valves and internal drain hoses up to the drain connections on
the dryer cabinets. The user must install a separate discharge
line at the drain connection to carry off condensate to an envi-
ronmentally approved condensate collection/disposal system.
Piping or copper tubing 1/2 inch or larger is recommended
for condensate discharge lines. Install the drain lines so that
condensate can be seen as it drains.
Electrical Connections
The dryers are constructed according to NEMA Type 1 electrical
standards. Field wiring must comply with local and national fire,
safety and electrical codes. Installation must be in accordance
with the National Electrical Code.
IMPORTANT: Use copper supply wires only.
1. Dryer is designed to operate on the voltage, phase, and
frequency listed on the dryer serial number tag.
2. Electrical entry is through a hole in the back of the cabinet.
Route wires through the bottom of the electrical enclosure.
Connect power source to the terminal strip in the electrical
enclosure as shown on the electrical schematics included
in this manual.

NOTE: Refrigeration condensing unit is designed to run con-
tinuously and should NOT be wired to cycle on/off with the air
compressor.
Operation of dryers with improper line volt-
age constitutes abuse and could affect the dryer war-
ranty.
INSTRUMENTATION
ON/OFF Switch
The dryer is equipped with an ON/OFF switch on the front panel.
A light signals when the dryer is on.
Dryer System Monitor (DSM)
The Dryer System Monitor (DSM) has LED type dew point tem-
perature indicator and operating time control for the electronic
drain valve. When the dryer is running normally, the green LED
will illuminate. If the red LED is illuminated, there is a need for
the dryer's operating condition to be checked. If all LEDs are
illuminated, the sensor for the dew point temperature indicator
has malfunctioned.
The automatic drain valve controls allow the period of drain
opening to be set from 1 second to 9 seconds and drain valve
closed time to be set from 0.5 minutes to 15 minutes. When the
Drain Push-to-Test button (5) is pushed for one (1) second, the
Drain LED (6) will illuminate and the drain port opens with a click.
Automatic Drain Valve
All models are equipped with an electronic drain valve that au-
tomatically discharges condensate from the dryer. Drain valve
operation is controlled by a drain valve timer. The drain opening
can be set from 0.5 seconds to 9 seconds. The drain cycle can
be set from 0.5 minutes to 15 minutes.
Drain valve adjustments are made on the Dryer System Monitor:
1. Press the Selection (4) and Enter (5) buttons at the same
time for 3 seconds, the On Time Setting Mode LED (3) will
start to blink, and the illuminated LED on the Dew Point
Temperature Indicator LED (2) will identify the factory set-
ting for "On Time". (See table)
2. Press and release the Selection button (4) to sequence from
left to right until reaching your selection. The red LED is
not used.
3. To store the "On Time", press the Enter button (5) and set
the "Off Time" using step 2.

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.

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.
4. Energize Dryer: Turn disconnect switch to "ON" position.
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
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.

MAINTENANCE
The dryers require little maintenance for satisfactory opera-
tion. 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 war-
ranty 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.
Monthly Maintenance
For air-cooled models, it is recommended to inspect the con-
denser coils monthly. If necessary, remove dirt or other particles
with compressed air from an OSHA-approved air nozzle that
limits its discharge pressure to 30 psig (2.1 kgf/cm²).
For water-cooled models, clean strainer monthly, more often
if required. Shut off water, remove small plug to relieve pres-
sure, then remove large plug to remove strainer. Clean strainer
and replace.
Electronic Drain Valve Disassembly and Servicing
The valve body is attached to the valve strainer which is attached
to the heat exchanger vessel.
Do not disassemble drain valve timer or attempt
to repair electrical parts. Replace timer if defective.
The drain valve discharge condensate through a full-port drain
opening. The valve body may need to be cleaned under condi-
tions of gross particulate contamination.
To disassemble the drain valve body for cleaning and other
maintenance:
1. Turn power switch off.
2. Disconnect main power supply to dryer.
3. Depressurize unit.
4. Lock out and tag power supply in accordance with OSHA
requirements.
If power supply is not connected and unit is not
depressurized before disassembly, serious personal injury and
valve damage may result.
5. Removes hoses that connect the drain valve to the drain
discharge fitting and remove the valve from the drain valve
strainer.
6. Remove screw and washer from front of the drain valve.
7. Remove the power supply connector and gasket (with the
timer assembly if attached) from the solenoid coil housing.
Do not damage or lose the gasket.
8. Remove coil fixing nut from top of solenoid coil housing.
9. Lift solenoid coil housing off solenoid core in valve body.
10. Unscrew solenoid core from valve body.
Once the drain valve is disassembled, the following maintenance
can be performed.
1. Inspect internal parts of valve body; clean or replace as
required.
NOTE: Replace solenoid valve if component damage is
observed.
2. Remove debris from valve body.
3. Wipe solenoid core components with a clean cloth or blow
out debris with compressed air from an OSHA-approved air
nozzle that limits its discharge pressure to 30 psig.
4. Check that the plunger assembly is clean and moves freely
in housing.
5. If timer is attached to valve body, check electrical continuity
across timer assembly.
To reassemble the drain valve, reverse the sequence of
the preceding steps. After the drain valve is reassembled,
connect the main power supply to the dryer.
When the dryer is returned to service, check the drain
valve for air or condensate leaks; tighten connections as
required to correct leaks. Check the drain cycle; adjust
the timer according to the procedure in the drain valve
adjustment section.

FIELD SERVICE GUIDE
Problems most frequently encountered with refrigerated dry-
ers are water downstream of the dryer and excessive pressure
drop. Most causes can be identified and remedied by following
this guide.
Closed refrigeration systems are potentially dan-
gerous. Work on the refrigeration system must be done only
by a competent licensed refrigeration mechanic. Do not release
fluorocarbon refrigerants to the atmosphere. Do not discharge
liquid refrigerants into floor drains. Refrigerant vapors may ac-
cumulate in low places. Inhalation of high concentrations may be
fatal. All refrigerants must be recovered per EPA requirements.
Do not smoke when a refrigeration leak is suspected. Burning
materials may decompose refrigerants, forming a toxic gas or
acids that may cause serious injury and property damage.
Before dismantling any part of the dryer or compressed air sys-
tem, completely vent the internal pressure to the atmosphere.
