CORRECTIVE MAINTENANCE

Wetrok machines are tested in the works for safety. For reliable operation and maintenance of value, regular servicing must be performed.
Servicing shall only be performed by the Wetrok Service Department or authorised specialists.
4.1 Fault finding and rectification
• Paper filter bag overfilled?
• Suction pipe, suction hose or nozzle obstructed?
• Inlet filter coated with dust?
• Exhaust air filter obstructed?
• Secondary air valve open at handle?
• Motor shut off by thermal overload switch (overheating)?
The suction motor of the Monovac 6 and 11 is provided with a thermal overload switch. This shuts off the motor automatically if it overheats. After coo-
ling off (may last up to 30 minutes), the motor starts up again.
5 SPECIAL INLET FILTER FOR MONOVAC 6 AND 11
An ultrafilter (for airborne particles) and a washable polyester filter are available as special accessories for the Monovac 6 and 11. Both may be attached
to any machine in place of the inlet filter without any conversion work. For assembly see the section „Checking and replacing the inlet filter".
