The unit should be located in a laboratory or clean industrial environment
where ambient temperatures are inside the range of +55°F to +95°F (+13°C
to +35°C). The unit will retain its full rated capacity in ambient temperatures
to approximately +75°F (+24°C). Above +75°F, reduce the cooling capacity
1% for every 1°F above +75°F, to a maximum ambient temperature of
+95°F. In degrees Celsius, reduce the cooling capacity 1% for every 0.5°C
above +24°C, to a maximum ambient temperature of +35°C.

The unit has an air-cooled refrigeration system. It must be positioned so the
air intake and discharge are not impeded. On models HX-75 through HX-
150, air is drawn through the left side of the unit and discharged through the
right and rear. A minimum clearance of 2 feet (0.6 meter) on these three
sides is necessary for adequate ventilation.
On models HX-200 — HX-750, air is drawn through the front of the unit and
discharged through the side and rear. A minimum of 5 feet (1.5 meters) on
all four sides of the unit is necessary for adequate ventilation.
In some applications where space is at a premium, the minimum ventilation
clearance can be compromised. However, consult our Sales Department
before positioning the unit in a location with less minimum clearance than
listed above. Inadequate ventilation will cause a reduction in cooling capacity
and, in extreme cases, compressor failure.
Excessively dusty areas should be avoided and a periodic cleaning schedule
should be instituted (see Section VII, Condenser Cleaning).
Refer to the table below to determine the approximate amount of air intake
required for the unit to retain its full rated capacity. If the air intake does not
meet these standards, cooling capacity will be derated.
