General description
The Vernacare Compact Plus macerator is designed to dispose of Vernacare single use
products, human waste, toilet tissue and maceratable wipes. No other materials should be
placed in the machine. Items to be disposed of are placed in the hopper; the disposal cycle
breaks down the contents of the hopper and disperses it in water to form a fine slurry. During
the cycle the contents of the hopper are sealed inside the machine by the lid seal and the
drain valve. At the end of the cycle the slurry is discharged to the drains by opening the drain
valve.
The lid is opened and closed by use of a foot sensor, the operator places a foot below the
machine on the spot of light projected on the floor to open or close the lid. There are two
modes of operation: as standard the machine will be in auto-start mode in which case the
disposal cycle will start automatically each time the lid is closed; in manual mode the
disposal cycle is started by pressing the start button.
The disposal cycle lasts around 3 minutes during which time water is added to the hopper
and the waste materials are broken down by the cutter motor blades. At the end of the cycle
the drain valve opens to allow the contents to drain and the inside of the machine is rinsed
with clean water and deodoriser is added.

Safety related control functions
The cutter blades in the base of the hopper are potentially hazardous. To prevent operators
or maintainers being exposed to the hazard of moving blades there is a safety control
system. The control system will not allow the motor to be energised until the lid is closed and
locked. There is a magnetic sensor that switches when the lid is in the closed position and a
micro-switch that switches when the lid lock is in the locked position. There is a second
independent control which inhibits the inverter (variable frequency drive) output to the motor.
Interfering with or attempting to defeat any of these safety related components is potentially
dangerous. Any work on the control system should only be carried out by an authorised
Vernacare technician.
