A, B, C – dimensions of the chamber;
a, b, c – spaces between the walls and the load;
a= A x 0,1
b= B x 0,1
c= C x 0,1
Working volume (space)
V = (A-2a) x (B-2b) x (C-2c)
Close the electric Furnace’s door.
Turn the switch (Pic.11, Pic.12) on. The light indicates that the Furnace is switched on
(just in Pic. 11).
Set the necessary program by following the instruction of the temperature controller.
If the Furnace is equipped with a switch, as shown in Fig. 12, by pressing the red button,
you can close the switch in the off position (Fig. 13).
After end of the work turn off the Furnace.
10. MAINTENANCE
The electric Furnace should be disconnected from the mains (power supply) and
cooled.
Open the door and loosen the door hinge fastening screws. Move the door to chamber
and clamp the screw. Close the door and check the door position. There must be no
gaps between the chamber gasket and the door and should close tightly. If gaps
remain – repeat the procedure.
Press the holder of the fuse, turn anticlockwise and take out from the socket. Change a
burnt-out fuse. Screw in the holder of the fuse in the reverse order. Ensure the fuse
holder is firmly tightened.
Once every six months examine visually the wires and electrical connections. If
necessary, tighten the contact screws.
When an operation is completed, clean the external surfaces of the electric Furnace,
except for the markings, with a water-dampened piece of cloth. Clean out the scale
from the heating chamber with a water-dampened piece of cloth. If there is necessity
clean the vents with a vacuum cleaner.
You are responsible for the correct boot sterilization.
