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.
Wall Mounting - Dryer may be wall mounted by using an
optional wall mounting bracket. clearance must be
maintained on all other sides as indicated.
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 122°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 normal. Consult your distributor if a
lower outlet air temperature is required.
Piping and Connections
Piping must be furnished by the user unless otherwise
specified. 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 recommended. 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 approved condensate collection/disposal
system. Securely anchor drain line to prevent whipping.
If clogging of the automatic drain is a problem, install a
particulate 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
frequency 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
