5. START UP
5.1 Delivery / Unpacking of kiln
The Toploader will usually be delivered on a pallet by a freight-forwarding agent. Immediately after delivery check the packaging
for any visible damage. Should you detect any damage, unpack the pallet together with the driver and check the goods again for
damage. If you detect any damage please enter details on the delivery note and let the driver countersign your remarks.
Keep one copy of the complaint for yourself. Inform the freight-forwarding agency immediately of the damage.
Complaints submitted at a later date cannot be taken into consideration.
5.2 Disposal of packing material
Contribute to a clean environment by disposing of wood, cardboard and plastic packaging material in your nearest waste disposal
plant.
5.3 Installation environment / Location
When selecting a suitable place for your kiln, please note the following guidelines and prepare the kiln environment accordingly:
• Place the kiln on an even surface.
• The distance to re proof wall vägg should be at least 30 cm.
• The distance to non re proof wall should be at least 50 cm.
• The distance to non re proof ceiling should be at least 150 cm.
• The oor or kiln base where the kiln is placed must be made of re proof material.
• Make sure that the kiln environment can be properly ventilated. Otherwise a ventilation system must be installed.
Please consult a qualied ventilation specialist to nd out whether a ventilation system is necessary.
• The protection foil on the kiln must be removed before the kiln is taken into operation.
• Keep away from children when the kiln is in operation or in the cooling down phase after ring.

Pict 2 Pict 3
Note! Remove the protection foil and check that the accessories stated below
was enclosed in the delivery (Pict 1).
• 3 pcs cordierite blocks
• 1 pcs ceramic tube for exhaust air
• 2 pcs sealing plugs (1 pcs is an extra spare part)
• 2 pcs plastic cap for kiln stand (1 pcs is an extra spare part)
• 1 pcs exhaust air socket and xing screws
You will also nd enclosed the controller, refractories and instruction manual for the controller and
the kiln. Take the ceramic tube out of the box and plug it onto the exhaust air opening on the left
side of the kiln (pict 2 and 3).
5.4 Assembly of kiln
Ver.200319-01

MANUAL SC-TOP
5.5 Installation of ventilation system
Screw the exhaust air socket (gure 4) into the hole on the left side of
the kiln. The opening has been located in a position that will allow
fumes and gases to be released through an exhaust air socket
(optional accessory). Plug the exhaust air tube into the exhaust air
socket (gure 5) and use the xing screw to x it to the socket.
Please note that the exhaust air tube only evacuates the main part of
the fumes from the kiln and has no capacity for evacuating the heat.
For that reason the exhaust air tube must not block or replace the room
ventilation. If the room already is well ventilated we recommend that the
exhaust air tube is not being installed.
5.6. Air supply handle
All SC-models are equipped with an air supply handle (gure 6) on the kiln base.
When the handle points to the left, the air supply is cut o󰀨. When the handle points to the right,
the air supply is open. You can signicantly increase the service life of the heating elements by
opening the air supply up to a temperature of 600 – 700°C.
Note! - The air inlet is only functional if the air outlet is fully open (no prop).
5.7. Connecting to power supply / controller
The kiln is equipped with a mains supply cable and CEE-stickpropp (pict 7). The power supply data can be seen on the type plate.
The power supply must be suitable for the requirements of the kiln. The plug must be located next to the kiln. Do not use extension
cables! The mains supply cable must not come into contact with the hot kiln!
Regional voltage uctuations are possible and will lead to uctuations in
the nominal output. In Sweden, the nominal voltage of 230 / 400 is
subject to voltage uctuations of 10%. If the voltage drops from 230
to 210 under load, the output of the kiln will be reduced by 16%.
Pict 8 shows the 14-pin plug and screw connection for the controller,
pict 9 or 9A. You will nd the black socket (gure 8) next to the electric
connection on the side of the switch cabinet.
First plug in the black plug of the controller. You might need to turn it a
little until it locks into position. Then turn the screw connection ring,
in order to protect the connection.
Note! Never use force, the pins in the
plug can be damaged.

5.8 Wall installation for controller G20-20
G20-20 is being delivered with a special wall xing device.
Please follow the manual enclosed with the controller.
5.9 Kiln and furniture initial ring
VARNING: First check that the protective foil has been removed from the entire kiln !!
Before starting to use the kiln in every day ring, you must carry out a dry ring. For this purpose make sure the exhaust air
opening on the side of the kiln is open. The ”burning-in” by means of a dry ring is important, in order to remove residual
moisture from the kiln walls. It also generates a protective oxide layer on the heating elements which will considerably
improve the service life of these components.
The ventilation handle must be in position ”open” during this ring process.
Settings for initial ring:
1) With controller G20-20: Choose program P2 ”Normal biscuit ring”.
2) With other controller: Set the heating time to 100°C/h and the top temperature to 1050°C. Set the soak time to 60 minutes.
IMPORTANT!
After the rst ring the tensioning belts of the stainless steel casing must be tightened with the straps, see part 8.
Pict 23Pict 22Pict 21
6.0 Exemple of kiln setting
Place the three (3) enclosed corderite blocks according to pict 21.
Place the rst batt on the blocks and make sure it is centered in the kiln (pict 22).
The batts are place on a 3-way point support. It is very important that the tubes are placed straight on top of each other and the
corderite blocks (pict 23).
This is a precausion in order to minimize the risk for cracked and bended batts. The batts will bend after some time of usage
and must be replaced.

MANUAL SC-TOP
7.0 Generell ring instructions
7.1 The controller
Please read the controller instruction manual carefully. The kiln is ready for operation after it has been connected
to the mains supply and the controller.
During the rst ring of the kiln we recommend that it is frequently checked.
7.2 Important about ring
• Do not place ammable objects near the kiln.
• The kiln may only be used in a well-ventilated room. In order to guarantee safe operation, the kiln may be only operated up to
an environmental temperature of 40°C.
• The kiln must be placed in a free-standing position in the room. Make sure that the heat release is not blocked.
• Do not place any objects on top of, or around, the kiln.
• Never open the kiln during operation or before it has cooled down completely. High temperatures are released and might cause
physical injury and material damage. The manufacturer of the kiln does not assume any liability in such cases!
• When ring materials which release hazardous gases and fumes, an exhaust air system must be installed that directs
these into the open air.
• Never use your kiln for ring inammable materials or food.
• Keep away from children when the kiln is operating or in the cooling down phase of the ring process.
• Do not re with reduced athmosphere in the kiln.

MANUAL SC-TOP
8.0 MAINTENANCE / CARE AND CLEANING
As the re bricks give o󰀨 residual moisture during the rst operation the volume of the kiln might change slightly. It is
therefore essential to readjust the tensioning belts of the stainless steel casing of the cover (gure 24) and main ring
(gure 25) after the rst rings (not applicable for Quattro and square or rectangular Toploader models).
8.1 Heating elements
Heating elements are subject to wear. Their resistance (Ohm) increases with every ring. Over the course of time this will lead to
delays in the ring cycle due to a drop in performance, especially in the upper temperature range. If there is excessive wear we
recommend that you replace the complete set of heating elements rather than just single elements.
Replacing individual elements might lead to variations in temperature inside the kiln.
Have a qualied electrician replace the heating elements!
Proper precausions for optimizing the life time of the heating elements:
• Avoid glaze contamination/spill on heating elements and bricks. In case this occurs, the glaze must be removed before next ring.
• Make sure there are no clay contamination/spill in the brick channels for the heating elements.
• Remove clay and stone dust regularly using a soft broom and a vacuum cleaner.
• Do not re higher in temperature than neccessary.
• Make sure the kiln chamber is well ventilated up to 600˚C
• Avoid reduction glaze ring.
• Do not use the kiln for wax melting.
A tip for the ring professional: Always keep a spare set of heating elements! In case of an
emergency this will save you unnecessary delay and allow you to continue ring as
quickly as possible.
Pict 25Pict 24
9.0 Good to know
• After the inital rings small cracks appears in the bricks.
These are so called hair cracks and is a normal development since the bricks are shrinking a bit when being dried out.
• Small brick particles are falling down on the top batt when opening and closing the air outlet.
This is normal for a new kiln but will reduce after some time of usage.
• When the kiln is ring in a high temperature, a thinn streak of light appears in the gap between the lid and the kiln.
This is normal for top loaded kilns with this lid construction but has no negative e󰀨ects on the kiln performance.
