1.1 Product Description

Pos: 5 /TD/Einleitung/Produktbeschreibung/Öfen/P r oduktbeschreibung-Laborofen L-LE-L(T)-LV ( T)-SKM-SW-HA @ 14\mod_1299596880427_51.docx @ 113276 @ @ 1

These laboratory furnaces are a high-quality product which will give you many years of
reliable service if they are properly cared for and maintained. One basic prerequisite is that
the furnace is used the way it was designed to be used.

During development and production a high priority was placed on safety, functionality and
economy.

Laboratory Furnaces are attractive thanks to their many advantages. These furnaces are

all-rounders for research and laboratory applications. They are made from expertly finished,
high-quality materials and are easy to operate. These furnaces are optimally designed for
incinerating and heat treatment. The very best insulation materials permit energy-saving
operation and fast heating times thanks to low heat storage and thermal conductivity.
Laboratory furnaces attain furnace chamber temperatures of max. 1100 °C (2012 °F), 1200
°C (2192 °F) or 1300 °C (2372 °F).

Other Characteristics of this Product are:

 All the models have a high-quality, multi-layered and energy-saving thermal

insulation

 Double-wall housing means low outer temperatures and solid stability. All furnaces

have housings made of textured stainless steel sheet.

 Good temperature uniformity provided by special air supply and exhaust system for

models LV/LVT .../… and LT …/…HA. For models LV/LVT .../… the system
delivers more than 6 air changes a minute. The incoming air is pre-heated, so that a
good temperature uniformity is ensured.

 There are furnaces with drop-down doors or lift doors
 Ceramic heating plates with integrated heating wire, protected against splattering and

exhaust-air for models L/LT …/… and LV/LVT .../…

 Model L/LT …/…/SW with scale and software (Controltherm MV) for annealing loss

specifications

 All the models are equipped with a controller which provides considerable safety

against operator mistakes. The furnace chamber temperature is measured and
regulated by a long-life thermocouple (NiCr-Ni Tmax < 1100 °C or PtRh-Pt Tmax >
1100 °C).

Additional Equipment

 Vent, vent with fan or catalytic converter.
 Over-temperature limiter with adjustable shut-down temperature for thermal

protective class 2 as specified in EN 60519-2 to protect the furnace and the ware
against overheating.

 Manual or automatic protective gas system Protective gas connection on the back side

of the furnace

 Digital interface RS 422, for example, for process control and documentation

provided by Controltherm MV software package.

 Base plates and catch basins to protect of the furnace and to enable easy charging
 Rectangular container, stackable for charging on several levels

1.3 Safeguarding against Dangers Posed by Over-Temperature

Pos: 9 /TD/Einleitung/Produktbeschreibung/Öfen/S i cherheitseinrichtung - Überwachung der Ofenraumte mperatur (TWB-TWW) - Beschreibung @ 37\mod_1362491214270 _51.docx @ 214092 @ @ 1

Over-temperature limiters with manual reset/with automatic reset to protect against over­temperature in the furnace chamber are available for Nabertherm GmbH furnaces either as
a standard feature (depending on the model series) or as additional equipment (customized
design).

The over-temperature limiter with manual reset/with automatic reset monitors the furnace
chamber temperature. The display shows the most recently set cut-off temperature. If the
furnace chamber temperature rises about the pre-set cut-off temperature the heating is shut
down to protect the furnace, the charge and/or the operating equipment.

Pos: 10 /TD/Sicherheit/Sicherheitssymbole/W arnhinweise-ISO-ANSI/Warnsymbol_Gefahr - Absic herung von Gefahren bei Übertemperatur am TWB-TWW @ 37\mod_136249 0404 893_51.docx @ 214067 @ @ 1

DANGER

• Danger caused by incorrectly entered cut-off
temperature at the over-temperature limiter with
manual reset/over-temperature limiter with automatic
reset.

• Mortal danger

• If, as a result of over-temperature from the charge and/or the

operating equipment, a charge is likely to be damaged at this pre­set cut-off temperature of the over-temperature limiter with
manual reset/over-temperature limiter with automatic reset, or if
the charge itself becomes a source of danger for the furnace or its
surroundings, the cut-off temperature must be reduced at the
over-temperature limiter with manual reset/automatic reset to the
maximum permissible value.

Pos: 11 /TD/Betrieb_Bedienung/Vor Inbetriebnahme des Ofens ist die Bedienungsanleitung... (TWB-TWW) - Text @ 37\mod_1362494080225_51.docx @ 214142 @ @ 1

Read the operating instructions of the over-temperature limiter with manual reset/with
automatic reset before starting the furnace. The safety sticker must be removed from the
over-temperature limiter with manual reset/with automatic reset. Any time a change is
made in the heat treatment program, the maximum permissible cut-off temperature (alarm
trigger temperature) at the over-temperature limiter with manual reset/with automatic reset
must be checked or re-entered.

Pos: 12 /TD/Betrieb_Bedienung/die maximale Solltemper atur des Wärmeprogramms Controller zwischen 5 °C und 30 °C (TW B- TWW) @ 39\mod_1363784610371_51.docx @ 218500 @ @ 1

We recommend setting the maximum setpoint temperature of the heating program in the
limiter between 5 °C and 30 °C, depending on the physical characteristics of the furnace,
below the trigger temperature of the over-temperature limiter with manual reset/with
automatic reset. This prevents an unwanted triggering of the over-temperature limiter with
manual reset/with automatic reset.

Safety

This Nabertherm system was designed and manufactured after careful selection of the
harmonized standards to be observed as well as other technical specifications. It therefore
corresponds to the state of the art, ensuring the highest possible degree of safety.

Only materials with known characteristics and melting temperatures may be used. Check
the material safety data sheets if necessary.

Use of the furnace for any other purpose whatsoever such as processing

products other than those intended or handling hazardous substances or

substances posing a health hazard constitutes improper use and must be

agreed upon with Nabertherm in writing.

Whether or not the materials used in the furnace can potentially corrode or destroy

the insulation or heating elements must be ascertained.

For furnaces with over-temperature limiters, the cutoff temperature must be set to prevent
overheating of the material.

Modifications to system equipment must be agreed upon with

Nabertherm in writing. It is not permitted to remove, bypass, or shut down safety devices.

The installation instructions and safety guidelines must be observed. Otherwise, the furnace

will not be considered as being used as designated, and all claims against Nabertherm
GmbH will be void.

Opening the furnace when hot (temperature greater than 200/392 °C/°F) can lead to
accelerated wear of the following components: insulation, heating elements, and furnace
housing.

Operating with power sources, products, operating equipment, additives,

etc. that are subject to the Ordinance on Hazardous Substances or cause

risks to the health of operating personnel in any way is not permitted.

- This furnace is designed for commercial use. The furnace must not be used

for heating food, animals, wood, grain, etc.

- The furnace must not be used as a workplace heater.

- Do not use the furnace to melt ice or similar materials.

- Do not use the furnace as a clothes dryer.

Note

See safety instructions in the individual sections.

DANGER

• Danger caused by incorrectly entered cut-off
temperature at the over-temperature limiter with
manual reset/over-temperature limiter with automatic
reset.

• Mortal danger

• If, as a result of over-temperature from the charge and/or the

operating equipment, a charge is likely to be damaged at this pre­set cut-off temperature of the over-temperature limiter with
manual reset/over-temperature limiter with automatic reset, or if
the charge itself becomes a source of danger for the furnace or its
surroundings, the cut-off temperature must be reduced at the
over-temperature limiter with manual reset/automatic reset to the
maximum permissible value.

Risks during Normal Operation!

Before switching the furnace on, check and ensure that only authorized persons are in the
working area of the furnace and that no one can be injured as a result of operating the
furnace.

Before starting production each time, check and ensure that all the safety equipment works
properly.

Before starting production each time, check the furnace for obvious damage and ensure that
it is operated only in a perfect condition. Report any defects to a supervisor immediately.

Before starting production each time, remove all materials and objects that are not needed
for production from the working area.

At least once every day (see also Servicing and Maintenance) check the following:

 Check the furnace for obvious external damage,

21

 Check that all safety equipment is working as intended (e.g. emergency stop button),
 Check all hydraulic or pneumatic hoses, make sure that they are not leaking and that

they are connected properly (if applicable),

 Check all gas and oil lines, make sure that they are not leaking and that they are

connected properly (if applicable),

 Check that the fan works properly (if applicable)

DANGER

• Danger caused by incorrectly entered cut-off
temperature at the over-temperature limiter with
manual reset/over-temperature limiter with automatic
reset.

• Mortal danger

• If, as a result of over-temperature from the charge and/or the

operating equipment, a charge is likely to be damaged at this pre­set cut-off temperature of the over-temperature limiter with
manual reset/over-temperature limiter with automatic reset, or if
the charge itself becomes a source of danger for the furnace or its
surroundings, the cut-off temperature must be reduced at the
over-temperature limiter with manual reset/automatic reset to the
maximum permissible value.

Check that Everything is Complete

Compare the delivered items with the delivery note and the purchase order documents.

Immediately notify the carrier and Nabertherm GmbH of any missing or damaged parts, as

complaints at a later date cannot be acknowledged.

Danger of Injury

When the furnace is being lifted, parts of the furnace or the furnace itself could topple over,
slip, or fall. Before the furnace is lifted, make sure no one is in the working area. Wear
safety footwear and a hard hat.

Safety Instructions

 Forklifts must be operated only by authorized personnel. The operator bears sole

responsibility for safe operation and the load.

 When the furnace is being lifted, make sure that the ends of the forks or the load do

not catch on neighboring goods. Use a crane to move tall parts, such as control
cabinets.

 Use only lifting equipment with sufficient load-bearing capacity.
 Lifting gear must be attached only to positions that have been designated for this

purpose.

 Attachments, piping, or cable conduits must never be used to affix lifting gear.
 Unpackaged parts should only be lifted with ropes or straps.
 Attach transportation equipment only to positions intended for this purpose.
 Lifting and securing equipment must conform to the provisions contained in accident

prevention regulations.

 Consider the weight of the furnace when choosing lifting and securing equipment.

(see Specifications)

 Stainless steel parts (including mounting elements) must always be kept separate from

unalloyed steel parts.

 Do not remove corrosion protection until immediately prior to assembly.

When setting up the furnace, the following safety instructions must be followed:

 The furnace must be installed in a dry room in accordance with the safety instructions.
 The table/supporting surface must be flat to enable the furnace to be installed straight.

Place the furnace on a non flammable surface (fire safety class A DIN 4102 –

Example: concrete, tiles, glass, aluminum or steel) so that any hot material falling
from the furnace cannot ignite the surface.

 The carrying capacity of the table must be designed to bear the weight of the furnace

incl. accessories.

 The floor covering must be made of nonflammable material so that hot material

falling out of the furnace will not cause the floor covering to ignite.

Despite good insulation, the furnace radiates heat from its external surfaces. If necessary,

this heat must be conducted away (a ventilation engineer must be consulted if required).

In addition, the furnace must be positioned a minimum safety distance (S) of 0.5 m on each
side and 1 m at the top away from combustible materials. In individual cases, more space
must be chosen in order to match the local conditions. The minimum distance away from

noncombustible materials may be reduced to 0.2 m at the sides.

Should gases or vapors escape from the charge, then sufficient air supply and ventilation at
the installation location or an appropriate exhaust gas line must be provided.

A suitable exhaust for the burner exhaust must be provided by the customer.

DANGER

• Danger associated with the use of an atomatic extinguishing
system

• Mortal danger posed by electrocution through wetness,
suffocation caused by extinguishing gas, etc.

• If automatic extinguishing systems are in place to fight fires and

protect the building, e.g. sprinkler systems, care must be taken
during their planning and installation that no additional hazards are
created, for example by extinguishing a pilot light, mixing
hardening oil and extinguishing water, the disablement of
electrical equipment, etc.

 Heats the gases and vapors from the furnace chamber to approx. 600 °C and feeds it

through the catalytic converter honeycomb. The converter incinerates most of the
organic substances, i.e. breaks them down into carbon dioxide and steam. This largely
eliminates any annoying odors (for example, during dewaxing).

 Warning! Inorganic substances such as heavy metals halogens, silicons and

particulates (even in small quantities) will destroy the catalytic converter!

 The temperature of the catalytic converter must be checked; from the start of the

program the converter must be operating at approx. 600 °C. A statement cannot be
made regarding residues which may be released into the environment. This is largely
dependent on the individual materials/embedding masses used and their compositions.
Exhaust air cross section: 120 x 120 mm

 Installation: Fasten the U-shaped brackets to the back wall of the furnace using the

screws included in the scope of delivery, slide the included section of pipe onto the
connecting piece of the furnace and screw the vent (with CAT) firmly to the bracket.
Plug the power plug into the socket on the back side (optional) of the switchgear or
into an external socket.

 These models come with a special exhaust gas pipe.
 Begin the installation by fastening the rectangular pipe to the inner housing of the

furnace with the screws included in the scope of delivery, then by fastening the rounds
section to the outer housing. The screws included in the scope of delivery are for this
purpose.

 Operating the furnace without this pipe results in a reduced air flow which is

insufficient for an incinerating process.

We recommend connecting an exhaust air pipe to the furnace to remove the exhaust gases.
For this purpose you can use a commercially available, metal exhaust gas pipe with NW80

to NW120. It must be installed continuously rising and fastened to the wall or ceiling.
Center the pipe over the furnace vent (for models with vent fan or catalytic converter, NW
120 is necessary.
The exhaust gas pipe must not be installed with a tight fit to the furnace vent pipe since this
would prevent any bypass effect. This is necessary so that not too much fresh air is sucked
in by the furnace. (An exception are the LV furnaces: Here the exhaust gas pipe NW80 can
be slid directly onto the furnace vent pipe.)

Vent : Position the exhaust air piping approx. 50 mm over the vent.
Exhaust air (model LV/LVT) or vent with fan : Exhaust air piping can be slid directly

onto the exhaust air pipe or vent.

Furnaces without exhaust air pipe or with catalytic converter : We recommend

feeding the exhaust air through a flue.

Caution

The exhaust gases can only be vented if the workspace is ventilated with an adequate fresh­air opening.

Caution

The customer is responsible for providing the masonry and roofing work necessary for
venting the exhaust. The size and design of the exhaust air system must be decided by a
ventilation expert. The accident prevention regulations applicable in the country where the
furnace is installed must be followed.

Carefully place the insert plate(s) *) (number of insert plates depends on the furnace
model), distributed across the floor of the furnace, starting from the middle. When placing
the insert plate(s) make sure that neither the door collar nor the heating elements are
damaged. Absolutely avoid touching the heating elements when inserting the heating
plate(s). Contacting the heating elements can result in their immediate destruction.

The furnace floor is made of high-quality refractory material but this material is highly
sensitive to impact or pressure.

Some models are supplied with one insert plate as a standard in order to prevent the soft
furnace floor from being damaged. Nabertherm accepts no liability for damage (e.g.
depressions) in the furnace floor resulting from not using these insert plates. *) Damaged
insert plate(s) must be immediately replaced with new ones (see the section "Spare
Parts/Wearing Parts").

The charge must be positioned in the furnace chamber, on the floor, as centered as possible.
This ensures uniform heating.

After charging, the furnace door must be closed carefully.

Installing the Scale on the L(T).../.../SW Model

 Insert the ceramic stamp included in the scope of delivery from below into the hole

in the floor of the furnace.

 Place the scale in the frame under the furnace. At the same time raise the pipe

carefully and place it on the supporting surface of the scale.

 To hold the pipe in place the support die must be slide into the space between the

pipe and the supporting surface of the scale. This is done by carefully raising the pipe.

 In the furnace chamber, slide the ceramic plate with its guide onto the pipe and

orient it precisely. The pipe must be free-standing on the scale and must not have any
contact with the furnace insulation to avoid falsifying the measurement results.

 Connect the scale with the power plug.

The furnace must first be heated up to dry out the masonry and generate a protective

oxidated layer on the heating elements.

During the heating up the furnace may give off unpleasant odors, which is due to the
release of binding agents from the insulation material. We recommend that the furnace
location be well ventilated during the first warm-up phase.

 Warm up the empty furnace over a period of roughly 6 hours

1)

to 1050 °C (1922 °F).

Hold this temperature for roughly 1 hour.

 Warm up LE …/… models to 1000 °C (1832 °F) (without the warm-up ramp).
 After the first warm-up phase, let the furnace cool down naturally to room

temperature.

 The furnace is now ready to operate

1) Warm-up ramp

Caution

This procedure must be performed at the time the furnace is commissioned, following the
replacement of heating elements or to regenerate the oxidated layer.

Charging the Furnace

The insulation is made of high-quality refractory material but is highly sensitive to impact.
Avoid contact when charging to prevent any damage.

To obtain a temperature distribution which is as uniform as possible it is advantageous to
leave space between the pieces and between the pieces and the side walls. Nabertherm
supplies insert plates (base plate) and the like to help you make use of the furnace chamber.

40

Loading a very large quantity of ware into the furnace chamber can substantially lengthen
the heating-up time.

The furnace heating system is interrupted if the door is opened. After the door is reclosed, it
is automatically switched on again (not applicable to LE …/… models).

If it can be at all avoided, do not open the furnace when it is hot. When it is necessary to
open the furnace at a high temperature, the time should be kept to an absolute minimum.
Make sure that operators wear the appropriate protective clothing and that the workspace is
adequately ventilated.

Always make sure that the door is completely closed.

Stainless steel sheet can discolor (especially if the furnace is opened while hot). This does
not impair functionality in any way. This is no reason for a complaint.

Caution LE …/… Models:

Continuous operation at maximum temperature can lead to increased wear of the heating

elements and the door seal. We recommend operating at approx. 50 °C below the

maximum temperature.
Caution for LT …/…HA Models:

The recirculating air motor starts when the program begins and cuts out again automatically

when the program ends and the furnace chamber temperature has dropped to below 80 °C

(176 °F). Above this temperature the furnace must not be switched off or disconnected
from its power source. If this caution is not observed the recirculating air motor may be

damaged.

Warning - Danger of Electric Shock!

For the protection of the operator and the furnace the heating program must be stopped
before the furnace is loaded. Ignoring this warning can result in electric shock.

Cracks in the Insulation

The insulation of the furnace and/or the side heating plates in the furnace (depending on the
furnace model) are made of very high-quality refractory material. Thermal expansion
causes cracks in the insulation even after only a few warm-up cycles and, in some
circumstances, in the side heating plates as well. But these have no impact on the function
or quality of the furnace. This is no reason for a complaint.

Warning! General Hazards!

Cleaning, lubrication, and maintenance tasks may only be performed by authorized experts
following the maintenance instructions and accident protection guidelines. We recommend
that maintenance and repair be performed by Nabertherm GmbH Service. Failure to comply
runs the risk of bodily injury, death, or significant property damage!

Warning - Danger due to Electrical Current!

Work on the electrical equipment may only be performed by qualified, authorized
electricians!

During maintenance work, the voltage supply to the furnace and/or switching system must
be switched off to prevent unintentional commissioning. Disconnect the mains power
connector due to reasons of safety.

Operators may only correct malfunctions which are obviously due to operational error!

Wait until the furnace chamber and attaching parts have cooled to room temperature.

The furnace must be visually inspected at regular intervals for damage. The interior of the

furnace must also be cleaned as required (e.g. vacuuming out) Attention: Do not bang

against the heating elements to avoid breaking them.

While work is being performed on the furnace, the furnace and work room must
additionally be ventilated with fresh air.

Safety systems removed during maintenance tasks must be replaced after the work.

Warning of swinging loads in the workshop (e.g. crane systems). Work under a lifted load
(e.g. a lifted furnace or switching system) is not permitted.

Safety switches and any limit switches present must be checked for function periodically
(BGV A3) or according to the national guidelines of the country of operation.

To ensure proper temperature regulation of the furnace, the thermocouple must be checked
for damage before every process.

If necessary, retighten the element holders (see chapter "Replacing the Heating Element").
Before carrying out this work, the voltage supply to the furnace and/or switching system
must be switched off (disconnect mains power connector). The regulations (BGV A3) or
corresponding national regulations in the relevant country of operation must be observed.

There are one or more contactors in the control system. The contacts of these circuit
breakers are wearing parts and must therefore be serviced and/or replaced regularly (BGV
A3) or according to the national guidelines of the country of operation.

The switching system cabinet (if available) contains vent grilles with integrated filter mats.
These must be cleaned and/or replaced at regular intervals in order to ensure sufficient
intake and outflow of air from the switching system. During melting operation, the
switching cabinet door must always be firmly closed.

Follow the procedure for shutting down the furnace system (in the "Operation" section).
Then the power plug must be pulled out of the socket. Wait until the furnace cools down
naturally.

Use commercially available detergent which is either water-based or non-combustible and
free of any solvents to clean the housing of any deposits; use a vacuum cleaner for the
interior.

Follow the labeling and the instructions on the packaging of the detergent.

Wipe the surface with a damp, lint-free cloth. The following detergents can also be used:

This list must be completed by the operator.

You must be sure that the cleaner does not damage the water-soluble and, hence, environmentally safe
paint (the clear should be tried first on an interior, normally unseen location).

Fig. 23: Detergent

Do the cleaning from beginning to end without breaks to protect the surfaces.
Remove the detergent completely from the surfaces by wiping them with a damp, lint-free
cloth.
After cleaning all the supply lines, check all the connections for leaks, loose connections,
abrasion and damage; report any shortcomings found immediately!

Please follow the section entitled "Environmental Protection Rules and Regulations"

Caution

The furnace, the furnace chamber and attached components must NOT be cleaned using a

high-pressure cleaner.

directly on the fuse.

 Insert the new fuse into the fuse holder. Make sure that the fuse is pushed fully into

the holder.

 Check that the power cable is not damaged. The power cable must not be damaged.

"Fix" and "secure" (adhesive tape) all moving parts and cushion and protect any projecting
parts against breakage.

Protect your electronic equipment against moisture and make sure that no loose packaging
material can get inside it.

Fill gaps in your packaging with soft but adequately firm material (e.g. foam mats) and
make sure that the equipment cannot slide around in the packaging.

If the goods are damaged during return transportation due to inadequate packaging
or some other breach of duty, the costs will be borne by the customer.

As a rule:

The furnace is sent without accessories, unless the technician expressly requests them.

Enclose a detailed description of the malfunction along with the furnace – this saves the
technician time and costs.

Don't forget to enclose the name and phone number of a contact in case there are any
questions.

Note

Return transportation may only be carried out according to the information given on the
packaging or in the transportation documents.

Note

Transportation and return transportation not covered by a warranty claim are paid for by

the customer.
