INSTALLATION
Ambient Air Temperature
Locate the dryer indoors where the ambient air temperature will be between 4
ഒ
and
43
ഒ
. Intermittent operation at ambient temperatures up to 43
ഒ
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 4
ഒ
. Such operation
may result in low suction pressure, causing freeze-up.
Location and Clearance
Mount the dryer on a level base and bolt down if the base vibrates. If the dryer is air
cooled, install it in a clean, well-ventilated area to reduce fouling of the condenser coils
with dirt and dust. Allow 6inches clearance on the sides and the front of the dryer for
cooling airflow on air-cooled dryers and for service access on air-cooled dryers.
System Arrangement
Liquid water adversely affects dryer performance. To prevent "slugging" the dryer with
liquid water, locate the dryer downstream of an aftercooler and a mechanical separator.
Install drain valves to discharge condensate that collects in these areas.
If the airflow is relatively constant and will not cause short term overloading of the
dryer, it is recommended that the dryer be located downstream of the receiver tank. If the
nature of the application is such that the air demand regularly exceeds the dryer flow
rating, it is recommended that the dryer be located upstream of the receiver.
For safety and convenience, install inlet and outlet shutoff valves and depressurization
valves at the locations indicated. These valves allow the dryer to be isolated and
depressurized for servicing. Bypass piping may be installed around the dryer for
uninterrupted airflow when the dryer is serviced. If the compressed air operation cannot
tolerate undried air for short periods, install a second dryer in the bypass line.
Compressed air systems commonly require filters to remove compressor oils, particulates,
condensed liquids and other contaminants. When an oil-removal filter is used, install the
