INTRODUCTION

DXR Series refrigerated air dryers use mechanical re-
frigeration to dry compressed air to pressure dew points
as low as 33°F-39°F. They deliver the required dew
point at specified inlet air temperature, pressure and air-
flow. Any change in these operating conditions may af-
fect performance. See Table 9 for rated capacity and
other dryer specifications.
To ensure continuing good performance and safe opera-
tion of the dryer, everyone who installs, uses or main-
tains it must read and carefully follow the instructions in
this manual.

SAFETY

DXR Series 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 ad-
justments are made before shipment.
Follow the maintenance schedules outlined in this man-
ual for good performance and safe operation. Mainte-
nance should be done only by qualified personnel with
proper tools.
Carefully read the following safety rules before pro-
ceeding with installation, operation or maintenance. The
rules are essential to ensure safe dryer operation. Failure
to follow these rules may 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 Inspec-
tion for instructions.
2. Compressed air and electricity have the potential to
cause personal injury or equipment damage. Before
doing any work on the dryer, be sure the electrical
supply has been locked and tagged and the internal
pressure of the dryer has been vented to the atmos-
phere.
3. Do not operate the dryer at pressures or tempera-
tures 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 authoriza-
tion.
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 haz-
ards caused by the use of unauthorized parts.

Safety Instructions

Safety instructions in this manual are boldfaced for em-
phasis. The signal words DANGER, WARNING and
CAUTION are used to indicate hazard seriousness lev-
els 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.

Safety Labels

Dryer labels providing important safety information are
included in this manual near corresponding text. If any
of the labels is missing or damaged, contact your local
distributor, request the label by its part number and ap-
ply it to the dryer.

Data Plate and Labels

The dryer data plate and dryer labels contain critical
safety and identification information. If any label or
data plate is missing or damaged, contact your local dis-
tributor and request a replacement.

RECEIVING AND INSPECTION

Inspect the dryer closely when it is received. Record
any indication of damage on the delivery receipt, espe-
cially if the dryer will not be immediately uncrated. Ob-
tain the delivery person's signed agreement to recorded
damages to facilitate future insurance claims.
Since the dryer is shipped F.O.B. New Castle, Dela-
ware, 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, no-
tify 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 abso-
lutely 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 goods
that have been damaged or lost in transit, you do so at
your own risk and expense.
