TYPICAL COMPRESSED AIR SYSTEM
INSTALLATION
Ambient Air Temperature
Locate the dryer indoors where the ambient air temperature will
be between 40°F and 100°F. Intermittent operation at ambient
temperatures up to 113°F 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 air-cooled dryers at ambient air temperatures
below 40°F. Such operation may result in low suction pressure,
causing freeze-up.
Call your local distributor if prolonged operation at ambient
temperatures above 100°F or below 40°F is unavoidable.
Location and Clearance
Mount the dryer on a level base. Install the dryer in a clean,
well-ventilated area to reduce fouling of the condenser coils
with dirt and dust.
Vapors and contaminants corrosive to copper and aluminum
must not be in the area of the dryer or air compressor intake.
Allow at least 6 inches clearance from the front and from the
condenser coil service access. Install the dryer with the frame
level. Anchor bolts are not required.
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 and the inlet air does not contain any liquid water.
Most compressed air systems require filters for removal of solid
and liquid contaminants. When an oil-removal filter is used, it
should be installed downstream of the refrigerated dryer. The
dryer will remove some entrained dirt, extending the life of
the replaceable filter element. Outlet air temperature may be
10 to 30 degrees higher than inlet air temperature. This is nor-
mal. Consult your distributor if a lower outlet air temperature
is required.
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 filters.
Inlet and outlet shutoff valves and a bypass valve are recom
-
mended. 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.
Removing Condensate
A separator with an automatic drain valve is supplied with each
dryer. The user must install a separate discharge line at the drain
connection to carry off condensate to an environmentally ap
-
proved condensate collection/disposal system. Securely anchor
drain line to prevent whipping.
If clogging of the automatic drain is a problem, install a particu
-
late filter before the dryer to keep solid particles from entering
the dryer. Contact your local distributor for the appropriate
particulate filter.
Electrical Connections
(See Figure 1)
Dryer is designed to operate on the voltage, phase and fre
-
quency listed on the serial number tag. Reference tag prior to
making electrical connection. Dryers are supplied with a cord
and plug. Install in receptacle of proper voltage.
Operation of dryers with improper line voltage
constitutes abuse and could affect the dryer warranty.
