1.0 Symbols and Warnings

1.0 Symbols and Warnings

1.1 Switches and Lights

Instrument switch: when the instrument switch is operated the

temperature control circuit is energised.

Heat light: the adjacent light glows or flashes to indicate that power

is being supplied to the elements.

Heat switch: the switch disconnects power to the heating elements;

unless this switch is OFF there is a danger of electric shock when

inserting objects into the product.

1.2 General Warnings

DANGER – electric shock. Read any warning printed next to this

symbol.

WARNING: risk of fatal injury.

DANGER – hot surface. Read any warning printed next to this

symbol.

WARNING: all surfaces of a product may be hot.

DANGER – read any warning printed next to this symbol.

Caution – Double Pole/Neutral Fusing

1.3 Warning Labels

On the front control panel there are 2 warning labels as shown in Figure 1.3.1; they are

numbered 7 and 8. These warnings must be followed for the safe operation of this

furnace.

7- Warning label - Do not operate without a work tube.

The furnace must not be operated without the correctly sized work tube

and correspond work tube adaptors or it could be possible for an

operator to access electrically live element coils that could cause serious

injury or death.

8- Warning label - Switch off the furnace before loading and

unloading.

The furnace heaters must be switched OFF using the heater switch, item

2 in Figure 1.3.1, when the furnace is being loaded or unloaded. The

work tube can become electrically conductive at high temperatures,

presenting a possible hazard to the operator. If element failure is left

undetected the element could collapse onto the work tube.

1.0 Symbols and Warnings

2.0 Installation

If the product has been transported or stored in humid conditions it

must be dried out completely before operating the furnace. Contact

Carbolite Gero Service for instructions.

2.1 Unpacking and Handling

When unpacking or moving the product, always lift it by its base or both ends of the

main body. Never lift it by the end insulation or by a work tube. It may take 2 or 3

people to lift the furnace, depending on the size and configuration.

NOTE: This product contains Refractory Ceramic Fibre (also known as

Alumino Silicate Wool - ASW). For precautions and advice on handling

this material see section 6.2.

2.2 Siting

Place the product on a level surface in a well ventilated area. Site away from other

sources of heat and on a non-flammable surface that is resistant to accidental spillage

or hot materials.

The surface on which the equipment is mounted should be stable and not subject to

movement or vibrations. The height of the mounting surface is important to avoid

operator strain when loading and unloading samples.

Ensure that there is free space around the sides and back of the product. Clear space is

required above the product to dissipate heat.

If the product is to be used in a process which could liberate hazardous gases, then it

should be installed together with a suitable fume extraction system.

Ensure that the product is placed in such a way that it can be quickly switched off or

disconnected from the electrical supply.

2.3 Setting Up

The horizontal furnace models must have a work tube fitted before being used. The

diameter of the work tube is a customer order option and therefore varies between

tube furnaces.

Note: If a metal work tube is being used in the furnace, ensure that it is

earthed. See 4.4.

2.0 Installation

Under no circumstances should any objects be placed on top of the product.

Always ensure that any vents on the top of the product are clear of any

obstruction. Always ensure all cooling vents and cooling fans (if fitted) are

clear of any obstruction.

Fitting the standard length work tube in a split tube furnace

No tools required.

The fitting of the work tube is as follows with reference to figure 2.3.3. Please note that

standard length work tubes are also referred to as tubes suitable for working in air.

They are 150 mm longer than the heated length of the furnace (see the table in section

10.0). Read section 6.2before fitting the work tube.

lRelease the top fixing clips

(9 in Figure 2.3.1, lift the

lid by the handle (1).

lPlace the work tube into

the bottom half of the fur-

nace in the tube adaptors,

between the work tube

end stops (5). Note that

the work tube might be a

tight fit when it is new and

may need to be twisted

backwards and forwards

slightly as it is placed.

lLower the lid by the

handle and refasten the

clips.

lNote in Figure 2.3.1 the

right hand furnace end

guard (8) is not shown so

that the end adaptor (3)

and tube end stop (5) can

be seen. It is not neces-

sary to remove the guards

to fit the work tube.

2.3.1 Figure - view showing how to fit the stand-

ard length work tube in the split tube furnace. Note

that the right hand furnace end guard (8) has been

removed from the view for clarity to show the end

adaptor and tube end stop.

stop for a standard length work tube on the split

tube furnace. Note that the right hand furnace

end guard (8) has been removed from the view

for clarity to show the end adaptor and tube end

stop.

Fitting the extended work tube in the furnace

Tools required: 4 mm Allen key.

Fitting of the work tube is as follows with reference to Figure 2.3.2, Figure 2.3.3, Figure

2.3.5 and Figure 2.3.6.

lBefore the extended work tube can be fitted, the work tube end stops for the stand-

ard length work tube (item 5 in figure 2.3.2 and figure 2.3.3) must be removed from

both ends of the furnace. This is done by removing the furnace end guard (8) and

the work tube adaptor brackets (4) to release the work tube end stop. The guards

and brackets should then be refitted.

lFit the tube support bracket, (15), figure 2.3.7. Use supplied M6 button head screws

and supplied washers.

lFit the extended work tube guard, (14), figure 2.3.8. Use supplied M6 button head

screws and supplied washers.

lRe-fit furnace end guard, (13), figure 2.3.9. Use supplied M6 button head screws

and supplied washers.

lIf supplied fit the optional tube end seal assembly as shown in figure 2.3.10. Refer

to manual MEN-ENDSEALS-01 for detailed fitting instructions.

lFit tube support bracket, (7), figure 2.3.11. Use supplied M6 button head screws and

supplied washers.

lFinally fit tube support collar, (5) and secure figure tight using (6) until tube is secure

to be used in a vertical arrangement. Fitting arrangement is shown in figure 2.3.10.

lFigure 2.3.5 - shows an exploded view of all the required parts.

lFigure 2.3.6 - shows the assembled parts as they would be used.
