prior to handling.
 Inspect heater before use.
 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 consid-
ered a heat sink).
 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

Read and understand this entire manual before operating this electric heater.
SUMMARY OF OPERATION
BriskHeat® DHCSR 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..” is designed for
poly drums / pails.
DHCSR series drum heaters are integrated with built-in
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. For additional information,
contact your local distributor or BriskHeat®.
5. Confirm heater maximum exposure temperature rating is suitable for
environment. The temperature of the internal heating element may run
up to 25% higher than the external surface of the heater. Use extreme
caution for applications that require a process temperature near the
maximum exposure temperature ratings of the drum heater.
- All Silicone rubber drum heaters except DHCX and DHNX
exposure temperature range: -60ºF to 450ºF (-51ºC to 232ºC)
- DHCX and DHNX exposure temperature range: -60ºF to 400ºF
(-51ºC to 204ºC)
T3: 292ºF (145ºC) high limit thermostat
T4A: 158ºF (70ºC) high limit thermostat
5. Do NOT connect to AC power until all installation steps are
completed.

INSTALLATION OF HEATER
1. Verify drum surface is clean, free of weld splatter, and not damaged
in anyway.
2. Select a suitable location on the drum, below the lowest expected
content level. For almost all applications, the heater should be mounted
on the bottom 1/3 of the drum.
3. Wrap the heater around the drum. Extend the spring attached to the
metal tab; latch the spring loop onto the hook on the opposite side as
shown in Figure 1.
4. Verify there are no air gaps between the heater and the drum.
Do not use metal tab as a handhold when extending the
spring.
The heater MUST make continuous contact with the drum.
Do not overlap the drum heater onto itself or another heater.

MOUNTING OF TEMPERATURE SENSOR (DHCX series)
1. Mount the temperature sensor as close as possible to the heater, on
the outside of the drum. It is best to mount the sensor vertically. Avoid
bending or coiling the capillary tube tighter than a 1/2” (13mm) radius.
NOTE: The sensing point is the entire length of the sheath (10.5” /
267mm). It is important that as much of the bulb’s surface is in contact
with the drum.
Do not immerse the sensing bulb into the contents of the drum.
2. Once an appropriate location has been determined, secure the
sensor to the drum using aluminum or fiberglass adhesive tape.
ADJUSTMENT OF TEMPERATURE SET-POINT
Do not operate the heater without a temperature controlling device (if
not installed). Failure to use such a device may result in in-process
damage or heater failure.
If the operating temperature is within 50ºF (10ºC) of the maximum
exposure temperature of the heater or if the temperature sensor/
controller or thermostat is controlling a process remote to the heater,
an integral high-limit temperature cut-out sensor/controller or
thermostat is required to protect the heater.
DHCH, DHCS, DPCH, DPCS, ECONO series
Adjust dial to desired setting. Drum heaters designed for metal drums
(DHCH, DHCS, and ECONO series) can be adjusted 50-425ºF (10-
218ºC). Drum heaters designed for poly drums (DPCH and DPCS se-
ries) can be adjusted 50-160ºF (10-71ºC).
DHCX series
1. Remove the two screws securing the metal plate opposite the
temperature sensor.
2. Remove the metal plate to expose the low and high limit set-point
controls.
3. Adjust the high and low temperature set-points to an appropriate
level for the environment. The low temperature set-point is the process
control. The high limit set point is connected to the high temperature
limit 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

Silicone Rubber Band Drum / Pail Heaters
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.
4. Replace the metal plate and secure with two screws.
CONNECTING HEATER TO AC POWER
1. The drum heater is designed to work at a specific voltage. Refer to
the lead wire label or stamp located on the heater for rated voltage and
wattage.
Failure to operate the drum heater at its rated voltage could cause
damage to the heater, surface being heated, or contents of drum.
All electrical connections must be made by qualified personnel and in
accordance with all local codes and regulations.
Properly sized circuit breakers must be used.
The end-user is responsible for providing suitable electrical protection
device. It is highly recommended that a ground fault circuit breaker
be used.
DHCH, DHCS, DPCH, DPCS, ECONO series
2. The power cable consists of three color-coded conductors, black,
white, and green. The black wire should be connected to Line 1. The
white wire should be connected to Line 2. The green wire should be
connected to earth ground. The power connections must be adequately
rated to electrically support the voltage and amperage of the heater.
The identification label located on the power cord displays voltage and
amperage requirements. Follow all local electrical codes for proper
electrical connections.
DHCX series
2. Connect the hazardous location approved plug to power source only
after all steps listed above are complete.
DHNH, DHNS, and DHNX series
2. Refer to external temperature controller instructions for power
installation instructions.

label located on the power cord displays the heater’s voltage
requirement.
Check to see if there is a resistance reading (not an open cir-
cuit) in heater using an ohm meter.

tripping
Validate that the circuit breaker is capable of handling the amp
requirement of heater. The identification label located on the
power cord displays the heater’s amperage requirement.
