Installation
The chiller has an air-cooled refrigeration system. Air is drawn in the front
of the chiller and discharged through rear and sides. Position the chiller
so the intake and discharge are not impeded. Inadequate ventilation will
reduce cooling capacity and, in extreme cases, result in compressor failure.
Avoid excessively dusty areas and institute a periodic cleaning schedule.
For proper operation, the chiller needs to pull substantial amounts of
air through a condenser. A build up of dust or debris on the fins of the
condenser will lead to a loss of cooling capacity.
The chiller will retain its full rated capacity in ambient temperatures up to
approximately +77°F (+25°C).
Make sure the voltage of the power source meets the specified voltage,
±10%.
The plumbing connections are located on the rear of the chiller and are
labelled and
for chillers with CP-55 pumps). Remove the plastic protective plugs from
both plumbing connections. Connect the

To fill the reservoir, remove the reservoir access panel and locate the
reservoir cap. Remove the cap and fill the reservoir with clean cooling
fluid.
For approved fluids refer to page 11.
Operation
Before starting the chiller, double-check all electrical and plumbing
connections. Make sure the circulating system is properly filled with
cooling fluid. Place the circuit breaker located on the rear of the chiller to
the up position.
To start the chiller, press
The LED indicates the status of the refrigeration system. It illuminates
to indicate the refrigeration system is removing heat from the cooling
fluid. As the operating temperature approaches the set point, the LED
flashes.
