Section III Installation and Operation
Site
Locate the unit on a sturdy work area. Ambient temperatures should be inside
the range of +50°F to +104°F (+10°C to +40°C). The maximum operating
relative humidity is 80%.
Never place the unit in a location where excessive heat, moisture, or
corrosive materials are present.
The unit has an air-cooled refrigeration system. Air is drawn through the
front panel and discharged through the rear panel. The unit must be
positioned so the air intake and discharge are not impeded. A minimum
clearance of 12 inches (30 centimeters) at the front and rear of the unit is
necessary for adequate ventilation. Inadequate ventilation will reduce
cooling capacity and, in extreme cases, can cause compressor failure.
Excessively dusty areas should be avoided and a periodic cleaning schedule
should be instituted (see Section IV, Condenser Cleaning).
Using 20°C water as a bath fluid, 115/60 units will retain their full rated capac-
ity in ambient temperatures up to +20°C. Reduce the cooling capacity
approxi-
mately
15 watts for every 1°C above +20°C, to a maximum ambient tempera-
ture of +40°C. For 230/50 units, reduce the cooling capacity
approximately
18
watts for every 1°C. Lower reductions in cooling capacity occur as the bath
fluid temperature increases.
