OPERATION

DHCH, DHCS, DHLS, DPCH, DPCS, and ECONO series:
This product is equipped with a dial adjustable thermostat temperature controller. A maximum
temperature is identified on the label: 425°F (218°C) or 160°F (71°C). Adjust dial to desired heat output .
To increase temperature output of the heater, turn the adjustable dial in the clockwise direction. To
decrease temperature output of the heater, turn the adjustable dial in the counter clockwise direction.
Note:
Ambient conditions will affect the dial's position in which the heater begins to heat. In cooler
temperature conditions the heater will begin to heat at a lower temperature position on the dial
and in warmer temperature conditions the heater will begin to heat at a higher temperature
position on the dial.
It is recommended that a thermometer is attached to the vessel being heated. Adjust the dial until you
achieve the desired temperature.
Note:
Changes in ambient conditions or in the temperature of the contents may cause the
temperature to shift over time.
For heating temperature sensitive materials that require a specific set-point or have a tight
tolerance temperature range Use of an external temperature controlling device is required. Select a
temperature controller with the accuracy necessary for the application and is approved for the location
and conditions where the drum heater is to be used. For lower temperature applications up to 212°F
(100°C) BriskHeat recommends the use of a TC4X Digital Temperature Controller. For higher
temperature applications BriskHeat recommends the use of a TTD Digital Temperature Controller.
Note:
If assistance determining a proper temperature controlling device is required for your
application, please contact BriskHeat or your local distributor for application assistance and
product solutions.
Install and connect the external temperature controlling device between the drum heater and the
electrical source as shown in Figure 2. Install the temperature controlling device in accordance with
manufacturer's installation instructions.
Ensure a grounded connection is provided and if the temperature controlling device does not support a
grounded connection, ensure an approved earth ground source is provided.
Mount the temperature sensor between the heater's metal tab and the outside of the container. Secure
the sensor to the container using appropriately rated aluminum or fiberglass adhesive tape.
Set the drum heater's temperature controlling dial to the maximum temperature setting. Adjust heater
output using the external temperature controlling device.

DHCX series Remove the two screws securing the metal plate opposite the temperature sensor.
Remove the metal plate to expose the low and high limit set-point controls. Adjust the high and low
temperature set-points to an appropriate level for the application. The low temperature set-point is the
process control. The high limit set point is connected to the high temperature limit indicator light.
Replace the metal plate and secure with two screws.
Do not adjust the low set-point higher than the high limit thermostat.
Do not adjust the low set-point higher than the high temperature set-point
connected to the indicator light.
NOTE: These heaters have a built-in, high limit thermostat that will prevent it from overheating.
T-3 rated heaters: 292°F (145°C) high limit thermostat.
T-4A rated heaters: 158°F (70°C) high limit thermostat.
Drum heater operation can now be controlled using the external temperature controlling device. Follow
operating instructions for the external temperature controlling device for adjusting the specific
temperature set-point.
DHNS and DPNS series Do not operate the heater without a temperature controlling device. Failure to
use such a device may result in material damage or heater failure. If normal operating temperature
exceeds 400°F (204°C), a separate high-limit temperature cut-out sensor/controller is required to protect
the heater.
Ensure maximum intermittent exposure temperature never exceeds 450°F (232°C).
