8. DISPOSAL
Appropriate waste sorting for the subsequent recycling, treatment and disposal in an environmentally sound way of the disused equipment avoids
negative effects on the environment or human health and favours the re-use or recycling of the equipment's materials.
Properly dispose of the product by disassembling it, presorting the contents, and sending them to the waste material treatment site.
Use the public or private waste collection service in accordance with the relevant local laws and regulations.
Consult your local municipality, the nearest waste disposal site, or the dealer who sold the product to you for information on proper disposal.
The crossed bin symbol on the equipment, or its packaging, indicates that the product must be collected separately from other
waste at the end of its useful life and not with mixed urban waste.
9. TROUBLESHOOTING GUIDE
CAUTION
Checks and corrective work must only be performed by skilled technician.
Before starting any work on mixers, make sure that the fuses have been removed or the mains switch has been switched off.
It must be ensured that the power supply cannot be accidentally switched on. All rotating parts must have stopped moving.
Make sure that no one is near the mixer when the power supply is reconnected to conduct checks that require voltage.
Failure to do so could result in death or serious injury.
Problem
1
The mixer fails to start or,
starts but stop immediately
2
The power supply circuit
breaker trips
3
The thermal protection
trips after a short operating
time
4
Leakage detection
5
Tripped residual current
device (RCD)
6
The mixer operates but the
flow is low or null
Possible cause
No proper power is supplied (i.e. power outage, voltage
drop, etc.).
Power cable is faulty or disconnected
Malfunction in control system (electrical panel)
Fuses blowed
Tripped circuit breaker
Tripped thermal protector
Leakage detector alarm
Tripped residual current device (RCD)
Tripped level control
Phase voltages too low or not balanced
Wrong electrical connection
Overload relay is set too low or is faulty
Stator windings are faulty
Foreign matter is wedged in the propeller, causing the
motor protector to trip
Blocked rotor
Foreign matter is wedged in the propeller, causing the
motor protector to trip
Internal moving parts are damaged
Phase voltages too low or not balanced
Fault in bearings
Starts per hour exceed the permitted number
Water ingress in the motor due to damaged cables, o-
rings or cable glands
Water ingress in the mechanical seal chamber due to
wearing or breaking down of mechanical seals or o-rings
Humidity in motor
Low motor winding insulation
Fault in cable
Propeller rotates in the wrong direction
Propeller blades are dirty, damaged or worn
Wrong mixer selection
