6.1.1 Technical maintenance Stage 1 schedule
1. Ask the operators who work with the machine for any issues related to the machine
and its operation.
2. Ensure that the machine is installed in accordance with the installation instructions
(see section 3).
3. Visually nspect the machine to detect any faults or broken parts. Make photo as
necessary.
4. Inspect supply cord, cable plug, and wall receptacle. Pay attention to mechanical
damages, damaged insulation, and colour changes. Replace damaged components.
5. Check the cable gland for supply cord. Cord must be tightly secured by the gland.
Tighten loosen gland.
6. Check control panel elements (push buttons, switch, thermostat), tighten their
mounting means as necessary.
7. Check the resistance between the grounding pin in the plug and accessible conductive
parts. The result must not exceed 0,2 Ohm.
8. Check connection and continuity of the equipotential bonding wire.
9. Make a note about conducted maintenance in the corresponding section of the
machine's factory certificate.
6.1.2 Technical maintenance Stage 2 schedule
1. Unplug the machine. Open the electric panel. Remove dust and debris from inside.
2. Inspect internal wiring; pay attention to mechanical damages, insulation colour
changing. Replace damaged wiring; restore markings on the wiring.
3. Inspect all electric components, including supply cord, cable plug, and wall receptacle.
Pay attention to mechanical damages, damaged insulation, and colour changes. Replace
damaged components.
4. Tighten contact joints and terminals of main current conducting parts, terminal block
and connectors. Face up pitted contacts as necessary.
5. Open the chamber, then remove the cover to get access to the heating elements
terminals and busbars, see Fig. 5. Inspect busbars (3), wires (2), and terminal studs of
the heating elements (4). If corroded or burnt, replace such parts. While replacing, use
anti-seize electroconductive copper based paste.
6. Check heating elements continuity. There should be no open or close circuit, nor
ground fault. Resistance should be around 21 Ohm for each element. Replace fault
elements. While replacing, use electro-conductive anti-seize paste.
