A. INTRODUCTION

This booklet includes our recommendations, hints and points of notice for you to have a safe and better service
from this equipment. We kindly ask you to carefully read this manual and only then to operate the furnace.

This insignia is used for the purpose of
warning you against risks involved.
Read carefully the notes when this sing is noted.

The insignia is to warn you for any risk of
damage to this equipment.

This insignia warns you of the hints to use

i

this equipment in better terms.

B. Information Related To Safety

1. Unpacking and Handling of the Furnace
Before operating the furnace please take note of following points.

• This furnace has been packed to minimize any risk due to transportation. Remove the

packing with care; avoid using any kind of force and removing packing inserts slowly.

It is extremely important to remove the packing inserts from

i

• Use furnace base while lifting and carrying the furnace.

• Always use two persons to carry.

• Always take note of the weight of furnace during placement.

• Do not operate the furnace if there is inflammable material around. Ensure that the risk of

fire is non-existent .Do not place the furnace on an inflammable surface.

• Placement should be in a well ventilated room, with no interaction with other sources of

heat. Do not place on an inflammable surface.

i

inside the furnace .Operating the furnace without removal
of safety inserts will cause heavy damage on the heating elements.

Air circulation, should be capable enough to remove any gas emission
due to come through the lid or furnace chimney. Almost all gas
emissions during operation can be hazardous for Human health

• Always give space of 30cm around the furnace to enable quick service. Do not close the

vents on the furnace body. These are required to cool down the system.

2. Electrical Safety

2.1 Electrical Connections

Due to safety none of the Labnics furnaces that use over 16 amps have a plug while
delivery. Main connection of furnace over 16 amps should be managed through a circuit
breaker and according to electrical diagram supplied together with this manual.

Electrical plugs even at low amperes (< 16amps) are prone to create

electrical arcs. We therefore strongly recommend using a circuit

breaker of appropriate amperes rather than the plug.

Any electrical connection to operate this furnace must be done by

a Qualified Electrician .Accordingly any repairs or maintenance

job requires a qualified technician.

The technician who is responsible of commissioning the furnace is

also responsible to act in accordance the rules of safety of European

Community. Technician is solely responsible of selection and use of

appropriate circuit breaker and earth connections.

•Power supply must be close enough to enable the operator to cut off

power easily in case of emergencies.

•Mains connection must incorporate an earthed isolating cut off switch.

Never use an electrically conductive tool within the furnace while in
operation

3. Human Health and Environmental Safety

1. Do not operate this furnace while there is any live substance in it.

2. Do not operate this furnace with flammable, explosive, poisonous etc. materials (Hydrogen,
LPG, Acetylene, Arsenic, TNT, Gunpowder etc.) inside. Labnics does not accept any
responsibility in case of any accident which might happen during any kind of process due to
the usage of materials mentioned above.

3. Do not contact or get in close proximity with flammable or explosive materials while this
furnace is operating or hot.

4. If at any times, this furnace is to be used under conditions of hazard to Human health, the
sole responsibility belongs to Operator. During such operation Operator is obliged to
provide the necessary conditions to minimize any risks involved.

5. If the lid of furnace is to be opened for a short cool down, any risks involved due to hot
discharge of air, belongs solely to Operator. We strongly advice of notification of personnel
around, against risks, to avoid any burns etc.

6. Labnics furnaces are manufactured in conformity with CE Electromagnetic Emissions
Directive. Even though so electromagnetic emissions can effect some sensitive equipment
such as Hearth Pace Batteries. Any one carrying such batteries should avoid close contact
with this furnace.

• Data concerning the Configuration Parameters are placed to controller during set

up. These parameters define many details such definition of thermocouple type,
temperature scale, PID values etc.

• All configuration parameters of the control system are “read only “. Changing these

parameters can have a detrimental effect to operation of furnace. If, any such
intervention is to be made Alser AS must be informed beforehand and asked to
provide a written consent. Otherwise we declare that the furnace will be void of any
