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
warranty.
