Safety Introductions
Please read these operating instructions before commissioning the device! Failure to observe these safety
instructions may result in damage to property and personal injury due to fire or electric shock!
Container heaters are only to be used in the upright position with the bottom of the container towards
the ground.
Container heaters are electrical equipment which may only be installed, connected and commissioned by trained per-
sonnel. Suitable electrical disconnecting and protective devices must be provided by the operator in accordance with
the relevant legislative regulations. We recommend the use of a residual current circuit breaker (RCD) with 30 mA.
All container heaters are suitable for operation in closed rooms and covered outdoor areas (degree of
protection IP 54). They must not be directly exposed to the weather.
Before commissioning
Remove the heating mantle from the packaging and make sure that it is not damaged. Never lift the heater by the
connection cable. Check that the mains voltage corresponds to the product label.
Always use the heater only for the intended container of the corresponding design and size. This applies in particular to
cambered plastic drums. Never use the heater without the suitable corresponding container!
When using on plastic containers, make sure of the maximum temperature (usually around +70 °C) and heating time
specified by the manufacturer are followed.
Keep informed (e.g. Safety Data Sheet) about which max. permissible temperature of the ingredient must
not be exceeded and whether flammable gases or vapors can escape (risk of fire and explosion!).
Make sure that the outside of the container to be heated is clean and dry.
Do not use additional heating or heat sources and never expose the container heater to temperatures above the nom-
inal temperature.
Assembly
Mount the heater in such a way that it lies smoothly and without folds on the container and that the heated areas
(recognizable by the inner pockets) do NOT overlap. Use the existing fasteners to secure the tank heater against slipping.
Do not use any fasteners other than those supplied and do not use any tools for assembly that could overstress the
material.
Always maintain a safety distance of at least 50 cm between two heated containers. The same applies to the distance
to radiators, warm surfaces, etc.
Commissioning
Do not connect the temperature controller to the power supply until after installation. To do this, remove the temper-
ature controller from its packaging and attach it to the fleece hook and loop pad provided on the heating mantle. Con-
nect the heating mantle (6+PE male) to the controller (6+PE female) using the round plug connection. Use the controller
to set the desired temperature set point. The temperature of the ingredient must be determined by separate fluid
sensor, if necessary.
Monitor the heating phase and the operation of the tank heater to observe any overheating or irregulari-
ties and initiate appropriate measures.
Open the lid or bungholes of the container so that it does not expand inadmissibly due to a pressure build-up during
heating. Monitor the fill level of the container while removing the contents. In the event of any leakage, take the con-
tainer heater out of operation immediately.
Caution: At temperatures above 60°C, there is a risk of burns on the surfaces of the containers. Protect
yourself against this.
Please ensure good ventilation. A heating mantle that is not in operation must be disconnected from the power supply.

Disassembly and storage
Switch off the heater and allow it to cool down completely. Disconnect it from the power supply before disassembly.
Then check it for damage and contamination and the connection cable for defects.
Do not use solvents or abrasive cleaners to clean the heater and never immerse it in liquids. To clean, gently wipe the
surfaces and controls with a damp cloth. Keep the heater away from sharp edges and pointed objects.
If you find defects or damage of any kind, do not put the heater into operation again. Do not attempt to
repair a damaged one yourself.
When the heater is not in use, it should be stored in a dry and clean environment in its original packaging. To do this,
gently roll it loosely along the pockets without squeezing or bending it.

1Introduction
Container heaters are used to heat drums and IBC containers made of plastic or metal in order to protect the contents
filled in them from frost, to heat them to a certain processing temperature or to facilitate their removal and dispensing
by reducing their viscosity.
The heating element is installed within inside pockets, which ensures even heat distribution and gives the heater a
structure that allows them to optimally fit the surfaces of the objects to be heated. They are equipped with a hook and
loop fleece to attach the digital temperature controller, which can be manually set to the desired temperature of up to
90 °C.
The light weight heater has integrated insulation to minimize unwanted heat loss. Equipped with robust pull straps and
snap closures, they can be quickly and easily be attached to and removed from standard containers and drums. Addi-
tional fastening straps or hooks that prevent them from slipping off the container are provided with the heater.
With their relatively low specific surface power, they are only suitable to a limited extent for rapid heating of liquids or
melting of solid ingredients. Much more, they are ideally suited for frost protection as well as slow heating and main-
taining the temperature directly at the tapping point of already heated containers. Insulation lids are available as acces-
sories to improve the efficiency and protect personal against burns on the hot surfaces of the containers.
With their high-quality materials and workmanship, the heaters provide a safe, efficient and durable solution for heating
of drums and containers in industrial applications when operated as intended.

5.4 Assemblage
Place the drum heater around the drum. The pre-installed (or enclosed) retaining straps help with mounting and at the
same time prevent sagging during operation (Figure 5.4.1). Align the two fastening straps according to a good fit on your
container. To protect against moisture and mechanical impact, the drum heater should not be placed directly on the
floor during this process. Close the buckles and tighten the tie straps evenly (Figure 5.4.2). The drum heater must fit
smoothly against the container without wrinkles and the heated areas (indicated by the inner pockets) must NOT over-
lap. The tightest possible fit will ensure efficient operation and uniform heating.

8Commissioning
Before commissioning, make sure that the operating manual of the temperature controller is available in order to obtain
detailed information about the settings and the control behavior.
Fundamental (WRL430PW): The hook and loop strip on the back of the temperature controller allows you to attach it
to the cover of the heating mantle. A hook and loop fleece pad on the heater is provided for this purpose, which is
located next to the cable with 0.3 m connection cable. Connect the 6+PE plug to the 6+PE socket of the temperature
controller. The drum heater is connected to the power supply using the controller connection cable (1). The controller
is switched on by pressing the up and down (2) keys simultaneously for a longer period of time. After switching on, the
controller performs a self-test (white indication light). If everything is OK, the display briefly lights up green (3) and then
drum heater begins heating. If an error is detected, an error message on display or signal LED (3) is displayed immedi-
ately.
Usually, after switching on, the set temperature has not yet been reached. The status LED (3) flashes blue slowly. This
means that the heating is active and the set temperature has not yet been reached. If the temperature is within the
good range of the setpoint, the status LED (3) is permanently green. Note: The controllers are delivered with a basic
setting (4) of 40°C. In the delivery state, the controller switches on automatically. Detailed information can be found in
the controller operation manual.
Figure 8. 1
Monitor the heating process and the behavior of the contents. Open the lid or bungholes of the IBC Container so that
it does not expand inadmissibly due to a pressure build-up during heating. In case of liquid leakage, im-mediately take
the IBC Container heater out of operation and remove it.

10 Service and maintenance
Maintenance and servicing should be carried out at regular intervals in accordance with the standards specified under
"Safety instructions", regulations and provisions applicable to the application. The function of the heating element, the
controller and the limiter must be checked and documented at least once a year.
The inspection must be performed after the heater has cooled down to ambient temperature and has been discon-
nected from the power supply. The heating mantle should not have any cuts, cracks or stitches. The insulation of the
connection cable must not have any visible damage. The heating mantle should have no accumulations of dirt, oil, grease
or foreign matter. Warning notices and type plates should be undamaged and clearly legible.
Heatiers in which the heating conductors are visible have been damaged or overheated. They must be taken out of
service immediately and must not be used again.
10.1 Repair
Conversions or modifications to the tank heater may impair its function. Repairs may only be carried out by qualified
personnel. Only original spare parts and accessories may be used.
Do not attempt to repair a damaged tank heater yourself!
Send it to our service department instead.
10.2 Return
For returns, we ask that you always decontaminate the heating mantle beforehand, confirm this in writing and enclose
it with the heating mantle as information. If you need a decontamination confirmation form, please contact your sup-
plier.
