4.2 Transport of kiln In case you need to move the assembled kiln, lift it from the kiln stand. Do not lift the assembled kiln from kiln handles or bottom handles. Do not move the kiln while it is connected to the power supply Do not move the kiln with the lid open Kiln handles and bottom handles are to be used during transportation of the kiln, ONLY IF the kiln is disassembled. -
Page 11: Maintenance
4.4 Maintenance Before proceeding to any maintenance or service operation Kiln main switch must be OFF, kiln must be unplugged or safety switch must be OFF 1. Kiln chamber must be kept clean, and any broken ceramic pieces must be taken out carefully. You can use a vacuum cleaner to clean the chamber. - Page 12 Kiln shelves must be smaller from the kiln interior diameter, as you need a gap between the shelf and kiln wall, for your hand to fit in, and for the hot air to circulate evenly. Supporting kiln shelves We advise you to support whole kiln shelves in 3 points. Always position the stilts one above the other for each layer, to avoid kiln shelf deformation or cracking.

5.2 Kiln loading During loading / unloading of the kiln, the main switch must be OFF, the kiln must be unplugged from power, or the power switch must be also to OFF position Make sure the lid is well supported before loading / unloading the kiln. -
Page 14: Kiln Cooling
5.3 Kiln Cooling Your new kiln features a multilayer insulation, which ensures minimum heating loss, and very slow cooling. To cool the kiln faster you can use the quick cooling position of the kilns lid support. This position keeps the lid open for few centimeters, and it helps the kiln to cool faster. -

Page 27: Error Messages
6.14 Error Messages If the ST535 detects a problem the buzzer will sound and an error message will be displayed. This error message will alternate with a display of kiln temperature. The segment number display will show where the error occurred. - Page 28 ERROR 7 Maximum room temperature exceeded. The internal temperature of the ST535 has exceeded an installer selectable limit. Possible causes: kiln room vent fan failure, kiln room too small, ventilation grills blocked, damper or bung left open, controller mounted too close to kiln.
- Page 29 All these error messages cause the ST535 to terminate the firing. The alarm buzzer will sound once per second. To reset the ST535 turn off the power to the instrument and have the fault investigated and rectified by your installer or kiln service engineer.

Page 30: Kiln Drying - First Firing
7. Kiln Drying – First firing Before using your kiln for firing you ceramics you must complete a first firing, which will allow the kiln insulation material to dry, and will create a thin protecting layer over the heating elements, which will make them last longer. It is also recommended to place all your kiln shelves in the kiln, in order to dry them out. -
