Brookfield Bath, Model TC-602 - Manual (Page 8)

Section 3 – Operation
3.1 Circulator Location
Locate the Circulator on a level surface, free from drafts and out of direct sunlight. Do not place it
where there are corrosive fumes, excessive moisture, high room temperatures, or excessive dust is
present.
Refrigerating/Heating Circulators must be a minimum of four inches (102mm) away from walls or
vertical surfaces so air flow around the unit is not restricted.
To help prevent voltage drops, position the Circulator as close as possible to the power distribution
panel and a properly grounded outlet. The use of an extension cord is not recommended.
3.2 Filling the Reservoir
The maximum fill level for the Circulating bath is one inch
(25mm) below the top of the reservoir. A liquid level that fully
covers the heater coil, pump, over-temperature sensor, and at
least one inch (25mm) of the temperature sensor must be
maintained. For optimum cooling efficiency, the bath fluid level in
Refrigerating/Heating Circulators should be kept above the
cooling coils at all times.
Minimum fill
level
Upon start-up, it may be necessary to add fluid to compensate
for the fluid required for external circulation. If the proper fluid
level is not maintained, the heater coil may become exposed and
possibly damaged.
Warning : These units are equipped with over-temperature protection (Safety Set). A low-liquid
level or failure to set the Safety Set and properly immerse the heater may result in heater burnout
and triac failure. While operating, do not allow the heater to contact any potentially flammable
materials, such as plastic trays or the sides of plastic tanks, as a fire hazard may result.
3.3 Power
An IEC power cord is provided with the Circulator. This power cord should be plugged into the IEC
receptacle on the rear of the Controller and then plugged into a properly grounded outlet. Make sure
that the power outlet is the same voltage and frequency indicated on the identification label on the
back of the Controller.
The use of an extension cord is not recommended. However, if one is necessary, it must be properly
grounded and capable of handling the total wattage of the unit. The extension cord must not cause
more than a 10% drop in voltage to the Circulator.
Once the unit has been connected to an appropriate electrical outlet, place the Circuit
Breaker/Power Switch on the rear of the Controller in the ON position. Four decimal points (….) will
appear on the digital display. DO NOT place the Power Switch on the front of the Controller ON until
the Safety Set has been adjusted to the desired temperature (see 3.4 below).
After filling the reservoir with fluid, you must set the Safety Set and the High Limit as well as your
desired control set point temperature.
3.4 Setting the Safety Set Point
The Safety Set feature automatically disconnects Controller power to the heater and pump in the
event that the reservoir liquid level drops too low or the Controller fails. The Safety Set is user-
adjustable between approximately 40° and 210°C. It should be set at least 5°C higher than the High
Limit temperature.
Use a flat blade screwdriver to rotate the Safety Set Indicator Knob to the desired temperature. Do
not force the knob beyond the stops at either end of the temperature value range.
