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.
DHCX series
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 series) can be adjusted 50-
160ºF (10-71ºC).
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.
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

PRIOR TO INSTALLATION
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..” is designed 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lLLED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 the temperature set-point, a “micro switch”
is acuated 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.
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.

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.
The heater MUST make continuous contact with the drum.
Do not overlap the drum heater onto itself or another heater.

Do not use metal tab as a handhold when extending the spring.

applications that require a process temperature near the maximum exposure
temperature ratings of the drum heater.
