INTRODUCTION
The dryers use mechanical refrigeration to dry compressed air. See Table 4 for rated
capacity and other dryer specifications.
To ensure continuous good performance and safe operation, everyone who installs, uses
or maintains the dryer must read and carefully follow the instructions in this manual.
SAFETY
The dryers are designed and built with safety as a prime consideration; industry-
accepted safety factors have been used in the design. Each dryer is checked at the factory
for safety and operation. All necessary adjustments are made before shipment.
Follow the maintenance schedules outlined in this manual for good performance and safe
operation. Maintenance should be done only by qualified personnel with proper tools.
Carefully read the following safety rules before proceeding with installation, operation or
maintenance. The rules are essential to ensure safe dryer operation. Failure to follow
these rules void the warranty or result in dryer damage or personal injury.
1. Do not install or try to repair a dryer that has been damaged in shipment.
See Receiving and Inspection for instructions.
2. Compressed air and electricity have the potential to cause personal injury or
equipment damage. Before doing any work in the dryer, be sure the electrical supply
has been locked and tagged and the internal pressure of the dryer has been vented to
the atmosphere.
3. Do not operate the dryer at pressures or temperatures above the maximum conditions
shown on the data plate.
4. Always supply electrical power that complies with the voltage shown on the data plate.
5. Do not readjust the dryer without factory authorization.
6. Work on the refrigeration system must be done only by a competent refrigeration
mechanic.
7. Use only manufacturer’s genuine replacement parts. The manufacturer bears no
responsibility for hazards caused by the use of unauthorized parts.

Safety Instructions
Safety instructions in this manual are boldfaced for emphasis. The signal words DANGER,
WARNING and CAUTION are used to indicate hazard seriousness levels as follows:
DANGER ------- Immediate hazard which WILL result in severe injury or death.
WARNING ------- Hazard or unsafe practice which COULD result in severe injury
or death.
CAUTION ------- Hazard or unsafe practice which COULD result in minor injury or
in product or property damage.
Data Plate
The dryer data plate contains identification information. If the data plate is missing or
damaged, contact your local distributor and request a replacement.
RECEIVING AND INSPECTION
Inspect the dryer closely when it is received. Record any indication of damage on the
delivery receipt, especially if the dryer will not be immediately uncrated. Obtain the de-
livery person's signed agreement to recorded damages to facilitate future insurance claims.
Since the dryer is shipped F.O.B. Factory, the manufacturer's responsibility for the
shipment ceases when the carrier signs the bill of lading.
If goods are received short or in damaged condition, notify the carrier and insist on a
notation of the loss or damage across the face of the freight bill. Otherwise no claim can
be enforced against the carrier.
If concealed loss or damage is discovered, notify your carrier at once and request an
inspection. This is absolutely necessary. Unless you do this, the carrier will not consider
any claim for loss or damage. The carrier will make an inspection and may grant a
concealed damage notation. If you give the carrier a clear receipt for the goods that have
been damaged or lost in transit, you do so at your own risk and expense.
The manufacturer is willing to assist you in collecting claims for loss or damage.
Willingness does not make the manufacturer responsible for collecting claims or replac-
ing material. Claim filing and processing is your responsibility.

INSTALLATION
Ambient Air Temperature
Locate the dryer indoors where the ambient air temperature will be between 4ഒand
43ഒ. Intermittent operation at ambient temperatures up to 43ഒwill 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 air-cooled dryers at ambient air temperatures below 4ഒ. Such operation
may result in low suction pressure, causing freeze-up.
Location and Clearance
Mount the dryer on a level base and bolt down if the base vibrates. If the dryer is air
cooled, install it in a clean, well-ventilated area to reduce fouling of the condenser coils
with dirt and dust. Allow 6inches clearance on the sides and the front of the dryer for
cooling airflow on air-cooled dryers and for service access on air-cooled dryers.
System Arrangement
Liquid water adversely affects dryer performance. To prevent "slugging" the dryer with
liquid water, locate the dryer downstream of an aftercooler and a mechanical separator.
Install drain valves to discharge condensate that collects in these areas.
If the airflow is relatively constant and will not cause short term overloading of the
dryer, 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 at the locations indicated. 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, install the

filter downstream of the 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 specified. Connections and fit-
tings 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 filters. Inlet and outlet shutoff valves and a
valved bypass are recommended. Piping should be at least the size of the inlet and out-
let connections to minimize pressure drop in the air system. See Table 3 for dryer inlet
and outlet connections.
Drains
Condensate must be drained from the dryer to prevent its reentrainment. 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 discharge line from the drain connection
and run it to a waste disposal collection system that meets applicable regulations. Pipe or
copper tubing inch or larger is recommended for condensate discharge lines. Install
the drain lines so that condensate can be seen as it drains.
Electrical Connections (See Figure 3)
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. Confirm that your line voltage is the same
as the voltage listed on the dryer data plate. Refer to Figure 3 for electrical schematics.
CAUTION
Operation of dryers with improper line voltage constitutes abuse and could
affect the dryer warranty.

HOW IT WORKS
Airflow (see Figure 4)
The dryers use refrigeration cooling to condense entrained moisture out of the air stream.
Warm saturated air enters the air-to-air heat exchanger where it is cooled by outgoing cold
air. The inlet air is further cooled in the refrigeration chiller. The cold, dry air is reheated by
incoming warm air as it passes back through the air-to-air heat exchanger. Using the
outgoing air to pre-cool the inlet air condenses up to 65 percent of the moisture out of the
inlet air before it reaches the chiller. Pre-cooling the inlet air reduces the heat load on the
refrigerant compressor, permitting the use of a smaller refrigerant compressor.
Refrigeration System
The refrigeration system is designed and fabricated in accordance with recognized com-
mercial/industrial practices. It consists of a compressor and the controls, safety inter-
locks and associated equipment necessary for safe performance.
All models use the constant pressure expansion valve. The constant pressure expansion
valve modulates the refrigerant flow in response to changes in the refrigerant pressure.
The constant expansion valve is adjusted at the factory; operation is fully automatic.
Color Indicator (HX76K~151K)
Figure 1. Color Indicator
The dryers (HX76K~151K) are equipped with a color indicator which indicates dryer
conditions as follows:
It is normal for the indicator color to be in the red zone when the dryer is first turned on
and then move to the green zone when the dryer reaches its normal operating
temperature. If this indicator is in the red zone during normal operation, turn the dryer off
to avoid compressor damage. Refer to the Field Service Guide, for additional information,
or call your local distributor.

ELECTRONIC DRAIN VALVE
The dryers(HX76K~151K) are equipped with an electronic drain valve that automatically
discharges condensate from the dryer. The drain valve and its controls are accessible from
the left side of the dryer. The electronic drain valve has two indicators and a test button to
help verify operation. Pushing the test button causes the drain port to click open. If either
indicator fails to turn on at the proper time, refer to the maintenance section of this manual.
Drain valve operation is controlled by an electronic timer. The drain opening can be set
from 0.5 sec to 10 sec. The drain cycle can be set from 0.5 min to 45 min.

* Operating check points
Check the following on a periodic basis:
A. Green power on light is illuminated.
B. Dewpoint indicator is in green area.
C. Condensate is discharging from drain.
Electronic Drain Valve Adjustment
To minimize air losses, the drain valve control time should be adjusted to open the drain
port just long enough to discharge accumulated condensate. Set the drain valve operating
time so that only air discharges at the end of the open period. Recommended initial
settings are a 1 to 2-second drain opening and 30 seconds drain closed time (cycle). If
liquid discharges as the port is closing, set the timer for a shorter cycle or a longer opening.

FIELD SERVICE GUIDE
Problems most frequently encountered with refrigerated dryers are water downstream of
the dryer and excessive pressure drop. Most causes can be identified and remedied by
following this guide.
DANGER
Closed refrigeration systems are potentially dangerous. 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 accumulate in low
places. Inhalation of high concentrations may be fatal.
Do not smoke while working on the refrigeration system or when a refrigerant leak is
suspected. Burning materials may decompose refrigerants, forming toxic gas or acids
that may cause serious injury and property damage.
The refrigerant valves are adjusted at the factory with the refrigerant system operating
and no airflow through the dryer. While the dryer is operating, the suction pressure may
fluctuate slowly with changes in the refrigeration load. To determine the suction
pressure, see the Refrigerant Suction Pressure Gauge mounted on the front panel.
