Installation Of Heater; Mounting Of Temperature Sensor (Dhcx Series); Adjustment Of Temperature Set-Point - BriskHeat DHCH Serie Manuel D'instructions

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.
6. 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 any way.
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.
WARNING
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 and 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 as possible.
WARNING
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
WARNING
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 and ECONO series
Adjust dial to desired setting. Drum heaters designed for metal drums (DHCH, DHCS and
ECONO) can be adjusted 50° to 425ºF (10° to 218ºC). Drum heaters designed for poly drums
(DPCH and DPCS) can be adjusted 50° to 160ºF (10° to 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.
4. 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.
