IMPORTANT SAFETY INSTRUCTIONS
DANGER
Do not immerse heater in liquid.
Keep volatile or combustible material away from
heater when in use.
Use heater only in approved locations.
Keep sharp metal objects away from heater.
All DHCX and DHNX heaters have T ratings
described in Article 501 of the NEC code. The
heaters should not be used in an area with a lower
T rating than the heater.
Failure to observe these warnings may result in electric
shock, risk of fire, and personal injury.
WARNING
End-User Must Comply to the Following:
Only qualified personnel are allowed to connect
electrical wiring.
Disconnect all supply power at the source before
making any power connections.
All electrical wiring must follow local electrical
codes and highly recommend following NEC
Article 427.
The person who performs the final installation /
wiring must be qualified for this work.
The end-user is responsible for providing a
suitable disconnecting device.
The end-user is responsible for providing suitable
electrical protection device. It is highly
recommended that a ground fault circuit breaker is
used.
DHCX and DHNX series: A NRTL (National
Recognized Testing Laboratory) listed
temperature controller must be used to control the
surface temperature of the heaters. The controller
must be approved for the area where it is located.
DHCX and DHNX series: Heaters provide surface
heating, Consult proper authorities for information
for safe heating of materials/contents of any
vessel heated by DHCX and DHNX heaters.
Failure to observe these warnings may result in personal
injury or damage to the heater.
CAUTION
Never handle the heater while it is in operation;
Always disconnect the heater from the power
source and allow to cool prior to handling.
Inspect heater before use.
Never operate a heater without a temperature
control device.
Do not wrap the heater over itself.
If spillage of foreign matter onto heater occurs,
disconnect from power source and clean after
heater is allowed to cool.
Never operate a heater without an appropriate
heat sink (device being heated is considered a
heat sink).
Do not operate heater above rated temperature
value.
Fasten heater to device using approved methods
only.
Do not repair damaged or faulty heaters.
Do not crush or apply severe physical stress on
heater or cord assembly.
Disconnect heater when not in use.
Use specified sized heater with same sized drum.
Do not use for other applications.
DHCX series: Never allow the full weight of the
thermal bulb controller to hang from the heater.
DHNX series: The metal enclosure must not
support more than 10lbs (4.5kg).
Failure to observe these warnings may result in personal
injury or damage to the heater.
A person who has not read and understood all operating Instructions is not qualified to operate this product.

Silicone Rubber Band Drum / Pail Heaters
WARNING
Read and understand this entire manual before operating this electric heater.
SUMMARY OF OPERATION
BriskHeat
®
Silicone Rubber Drum Heaters are designed to heat the contents inside either metal
or poly drums/pails. “DH..” and “ECONO” are designed for metal drums/pails. “DP..” for poly
drums/pails.
DHCH, DHCS, DPCH, DPCS and ECONO series
drum heaters are integrated with an adjustable
thermostat controller.
DHCX series
drum heaters are integrated with a dual set-point NEMA-7 temperature controller
and a high temperature limit indicator light designed to maintain temperature at a given set-point.
The temperature controller uses a liquid-filled sensing bulb to measure the drum temperature.
Once installed, the sensing bulb is in constant contact with the drum. The sensing bulb must be
installed on the drum as close as possible to the actual heater; this ensures safety as well as
accurate measurement and control. When the temperature of the drum reaches thetemperature
set-point, a “micro switch” is actuated and power is shut off to the heater. Once the temperature
decreases below the set-point, power is supplied to the heater to raise the temperature. The
constant feedback from the sensing bulb, coupled with the controller, enables the desired
temperature control of the drum heater.
DHNH, DHNS and DHNX series
drum heaters DO NOT include a temperature controller. These
heaters must be connected to an external control device approved for the desired location. These
heaters must not be operated without some form of temperature control.
PRIOR TO INSTALLATION
1.
Check for suspected damage to the heater like rips, punctures, etc.
2.
Verify surface to be heated is free from all sharp edges, weld splatter, rust, oil, etc.
3.
Check that the desired placement of the heater will not cause damage to the heater through
impact shock, vibration, ambient temperature, or by neighboring moving parts.
4.
Confirm voltage/wattage rating of heater is appropriate for power supply device or
temperature controller. The heater is designed to work at a specific voltage to heat properly.
