INSTALLATION
Ambient Air Temperature
Locate the dryer indoors where the ambient air temperature will
be between 45°F and 110°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
refrigerantdischargepressure(seeFieldServiceGuide).
Do not operate air-cooled dryers at ambient air temperatures
below 40°F. Such operation may result in low suction pressure,
causingfreeze-up.

Compressed air systems commonly require filters to remove
compressor oils, particulates, condensed liquids and other
contaminants. When an oil-removal filter is used, it should be

Removing Condensate
Condensate must be drained from the dryer to prevent re-
entrainment. The dryers are equipped with automatic drain
valves and internal drain hoses up to the drain connections on
the dryer cabinets. The user must install a separate discharge
lineatthedrainconnectiontocarryoffcondensatetoanenvi-
ronmentally approved condensate collection/disposal system.
Piping or copper tubing 1/2 inch or larger is recommended
forcondensatedischargelines.Installthedrainlinessothat
condensate can be seen as it drains.
Electrical Connections
The dryers are constructed according to NEMA Type 1 electrical
standards. Field wiring must comply with local and national fire,
safetyandelectricalcodes.Installationmustbeinaccordance
with the National Electrical Code. Confirm that your line voltage
isthesameasthevoltagelistedonthedryerdataplate.Refer
toFigure1forelectricalschematics.
Operation of dryers with improper line volt-
age constitutes abuse and could affect the dryer war-
ranty.

Dew Point Indicator
(Models HPR75 through HPR150)
All dryers are equipped with a dew point indicator which indi-
catesdryerconditionsasfollows:

Dryer System Monitor (DSM)
(Models HPR200 through HPR500)
The Dryer System Monitor (DSM) has LED type dew point tem-
perature indicators and electronic drain valve timing controls.
When the dryer is running normally, the green LEDs will illumi-
nate.IftheredLEDisilluminated,thereisaneedforthedryer's

NOTE: When the dryer is turned on, all LEDs will be illuminated.

The automatic drain valve controls allow the period of drain
openingtobesetfrom0.5secondsto9secondsanddrainvalve
closedtimetobesetfrom0.5minutesto9minutes.When
the "PUSH TO TEST" button is pushed, the drain valve opens and
remainsopenfortheadjusted"open"time.
Automatic Drain Valve
All models are equipped with an electronic drain valve that
automatically discharges condensate from the dryer. Drain
valve operation is controlled by a drain valve timer. The drain
openingcanbesetfrom0.5secondsto9seconds.Thedrain
cyclecanbesetfrom0.5minutesto9minutes.
Models HPR75 through HPR150 have the timer mounted directly
on the drain valve. For models HPR200 through HPR500, drain
valveadjustmentsaremadeontheDryerSystemMonitor(DSM).
