Quick Reference Operating Procedures
Operation
Before starting the unit, double-check all electrical
and plumbing connections. Make sure the bath is
properly filled with fluid.
To start the unit, press
. To turn the unit off
press
again.
The
LED indicates the status of the heater. It
illuminates to indicate the heater is on.
The
LED indicates the status of the refrigera-
tion system. It illuminates to indicate the refrigera-
tion system is removing heat from the cooling fluid.
Temperature Adjustment
To display the temperature setpoint, press
on
the controller. The indicator will illuminate and
the display will flash the current setpoint value. To
adjust the temperature setpoint, press the arrow
buttons until the desired temperature setpoint is
indicated. Press
again to confirm the change.
The display will rapidly flash the new value for a
short time and then return to the recirculating fluid
temperature.
Periodic Maintenance
Periodically inspect the reservoir fluid. If cleaning is
necessary, flush the reservoir with a cleaning fluid
compatible with your application.
The reservoir fluid should be replaced periodically.
Frequency depends on the operating environment
and amount of usage.
Before changing the reservoir fluid ensure it is
at a safe handling temperature.
Periodic vacuuming of the condenser fins is neces-
sary. The frequency of cleaning depends on the
operating environment. We recommend a monthly
visual inspection of the condenser after initial
installation. After several months, the cleaning
frequency will be established.
Installation
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 scheduleshould be instituted.
The unit will retain its full rated capacity in ambient
temperatures up to approxi75°F (+24°C).
Make sure the voltage of the power source meets
the specified voltage, ±10%.
The pump connections are located at the rear of the
pump box and are labelled
and
. These
connections are angled upward so the recirculating
fluid will drain back into the reservoir when the
hoses are disconnected. Both connections are
capped with stainless steel serrated plugs.
The pump lines have ¼" MPT for mating with
standard plumbing fittings. For your convenience
stainless steel adapters, ¼" FPT to
3

" O.D.
serrated fitting, are provided.
The bath work area has a high and low level marker
to guide filling. The markers are 1 inch horizontal
slits located in the center of the stainless steel
baffle separating the work area and the pump
assembly. The correct fluid level falls between
these two markers. The unit will not start if the fluid
level is below the lower slit.
