Silicone Rubber Band Drum / Pail Heaters

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

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.

NOTE: The sen

sing 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 ﬁ berglass adhesive tape.

IMPORTANT SAFETY INSTRUCTIONS

A person who has not read and

understood all installation instructions

is not qualiﬁ ed to install this product.

 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 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 speciﬁ ed 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.

Approvals valid only when installed in

accordance with all applicable

instructions, codes, and regulations.

Agency Approvals

DHCH, DHCS, DHNH, DHNS, DPCH,

DPCS, DPNS, DPNH, DPNS, ECONO,

and Custom series

End User Must Comply to the Following:

 Only qualiﬁ ed 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.

 Final installation / wiring is to be inspected by the

authority who has jurisdiction in the area that the

heater is installed.

 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 blankets. 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.

 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. The T rating is

stated in marking on the heater.

Failure to observe these warnings may result in

electric shock, risk of ﬁ re, and personal injury.
