INTRODUCTION
SDR Series refrigerated compressed air dryers use me-
chanical refrigeration to remove moisture from com-
pressed air, providing dew points as low as 33°F – 39°F.
They deliver the required dew point at specified inlet air
temperature, pressure and flow. Any changes in inlet air
temperature, pressure or flow may affect the pressure
dew point. See Table I for rated capacity and other dryer
specifications.
To ensure continuing good performance and safe opera-
tion of this dryer, everyone concerned with its installa-
tion, operation and maintenance must read and carefully
follow the instructions in this manual.
SAFETY
SDR 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 proceed-
ing 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. 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 disconnected and the internal pres-
sure of the dryer has been vented to the atmosphere.
2. Never install or try to repair any dryer that has been
damaged in shipment. (See Receiving and Inspection
for instructions.)

Performance data obtained in accordance with Compressed Air and Gas Institute (CAGI) Standard number ADF 100 – Refrigerated Compressed Air Dryers –
Methods for Testing & Rating. Rating conditions are 100°F inlet temperature, 100 psig inlet pressure, 100% relative humidity, 100°F ambient temperature and 5 psi
pressure drop. Pressure drop may exceed 5 psi when the dryer is sized for a dew point higher than 33°F - 39°F. Contact your local distributor for estimated pres-
sure drop.

3. Do not remove the covers or loosen or remove any
fittings, connections or other devices when the dryer
is operating. Air under pressure within the dryer can
cause severe injury or death.
4. High voltage in the motor control box is dangerous.
The dryer must be installed in accordance with rec-
ognized electrical codes. Before performing any
work on the electrical system, disconnect power
from the dryer.
5. Do not operate the dryer at pressures higher than
those specified on the dryer label. Excessive pres-
sure may result in severe injury or death.
6. Use only genuine replacement parts from the dryer
manufacturer. Manufacturer bears no responsibility
for hazards caused by the use of unauthorized parts.
7. Before operating the dryer, read the instructions
thoroughly.
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 se-
vere injury or death.
WARNING—Hazard or unsafe practice which COULD
result in sever injury or death.
CAUTION—Hazard or unsafe practice which COULD
