Waste Disposal Units
One of the advantages that the Franke Turbo Permanent Magnet Motor disposers have over standard Induction Motor WDUs is the starting torque - Franke Turbo WDUs are up to full speed within the first revolution.
Most jams occur at start-up because food waste will be stuffed into the disposer until it is full (this is not the correct way to use the disposer but is more reality).
The Franke Turbo's initial high starting torque gives it the advantage to break through the waste already put into the disposer. Under similar conditions an induction motor disposer can jam as it tries to push the waste around while it builds up speed. When the induction type motor cannot push any more and becomes jammed the "Auto Reverse" feature gives the ability for the unit to run in the opposite direction to break away from the jam condition
As the overflow would normally connect to the Basket Strainer Waste, you need to purchase either a WDU Connector for a single bowl sink, or a WDU Converter for a bowl and a half sink. These can be purchased from our service agents
A Franke Turbo Waste Disposal unit consumes roughly the same power in one month to lighting a 100 watt light bulb for one hour, therefore operating costs are relatively low. The high torque fast grinding Franke Turbo units use very little water
The Franke air activated control switch button operates continuous feed waste disposal units from a point determined by the consumer, eg on the worktop or possibly even within the sink perimeter.
Air switches are safer than electric switches because they keep the electricity away from the users' hands. The air switch control mechanism usually mounts under the sink (or is incorporated into the Waste Disposal Unit itself), where it remains dry. From the activated control switch button, an air tube connects with the switch controller, which in turn operates the unit.
The benefit is that the operational switch avoids the necessity to have a wall mounted toggle switch (which itself is electrical), and is therefore neater and safer to operate
Batch Feed model is activated by loading the chamber and rotating the WDU plug. Continous Feed models are operated by an Air Switch (or alternative) and waste is fed through the open neck of the unit. In both cases, a continuous supply of water is necessary whilst the WDU is in use
Yes - by following the following procedure:
- With the disposer mounted on the sink and line cord connected to a wall outlet receptacle, turn "ON" the wall mounted switch.
- If the disposer is "OFF", depress air switch actuator to turn the disposer "ON".
- With the disposer " ON " pull air switch hose from disposer connectionn and discard air switch actuator and hose.
- Turn the disposer "OFF" by turning off the switch, usually controlled by a wall mounted switch.
- Operation of disposer is now controlled in a typical manner by the wall mounted switch
