Site

The indentations on the unit's sides are designed to function as handles. Lift
the unit by the handles and locate it on a sturdy work area. Ambient tempera-
tures should be inside the range of +50°F to +80°F (+10°C to +27°C).
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 VI, Cleaning).
The unit will retain its full rated capacity in ambient temperatures up to
approximately +75°F (+24°C). Above +75°F, derate the cooling capacity 1%
for every 1°F above +75°F, to a maximum ambient temperature of +95°F.
In terms of Celsius, derate the cooling capacity 1% for every 0.5°C above
+24°C, to a maximum ambient temperature of +35°C.
Electrical
Requirements
Line voltage may be easily accessible inside the pump/control box.
Always unplug the unit prior to removing pump/control box cover.
Refer to the serial number label on the rear of the unit to identify the specific
electrical requirements of your unit.
Ensure the voltage of the power source meets the specified voltage, ±10%.
The unit construction provides extra protection against the risk of electric
shock by grounding appropriate metal parts. The extra protection may not
function unless the power cord is connected to a properly grounded outlet. It
is the user's responsibility to assure a proper ground connection is provided.
For 220 - 240 volt units supplied without a line cord, use a harmonized
(HAR) grounded 3-conductor cord, type H 0 5 V V - F , with conductors
listed below. A suitable cord end is required for connecting to the
equipment (see unit socket) and must terminate with an IEC approved
plug for proper connection to power supply.
