Frequently Asked Questions
Frequently Asked Questions:
Do Rensa Avskiljarteknik meet the requirement for CE-approval?
To comply with EU Machine Directive the BASE disposer must be fitted with an appropriate assembly/protection lid. Disposers with an assembly comply with the EU Machine Directive 2006/42/EC, EMC directive 2014/30/EU and Low Voltage Directive 2014/35/EU.
The directive is not applicable for installations on board ships as galley
installations are not included in the EEC´s Machine Directive.
What is the average generated volume of food waste per person?
As a general average 0,1–0,15 litre food waste is generated per person and meal. This includes preparation waste as well as leftovers on plate after meal. For example, if 500 persons are served it comes to 50-75 litre food waste.
What documentation is included with the delivery of the disposer?
Product sheet, installation instructions, wiring diagram, operation and safety instructions
Do disposers in Rensa Avskiljareteknik´s range meet with the requirement of Marpol?
This is to verify that the food waste disposer Mola Bas 1,25kW,2,5kW,4,0kW and 5,5kW manufactured by Rensa Avskiljareteknik AB, Sweden, are in compliance with regulations 4,5 and 6 in MARPOl Annex V REGULATIONS FOR THE CONTROL OF POLLUTION BY GARBAGE FROM SHIPS, as amended 2016 and 2019.
How often does the disposer require service and are there recommended service package available?
Rensa´s Mola series require that preventive service should be undertaken at 3-5 year interval, and that a complete service is made every 7-10 year.(depending one the use and wear of the disposer)
The ”small” service package includes items to be replaced when carrying out a preventative
maintenance and the ”big” service package includes when subject to wear.
What is the expected lifetime of the grinding unit?
About 7-10 years Depending on how much the disposer is used and what kind of food waste that is grounded.
What if food waste jams the grinding unit, and what is a jam release wrench?
If the disposer stops or does not start it could be that something got stuck in the grinding unit. A humming sound may be heard from the motor. The jam release wrench is used to dislodge the stuck material.
Place the tool over the centre plate of the grinding unit. Rotate the tool with changing direction of rotation. The method uses inertia in the rotation disc to generate counterforce If this is the case remove the object from the grinding unit.
Are all Rensa´s models delivered with supporting legs?
Disposer from 2,5kW and higher kW are delivered with three supporting legs.
Can Rensa´s free standing disposers be positioned in outdoor marine environments with the use of seawater as flushing water?
The standard Rensa´s cabinet is made of stainless steel AISI304 and not recommended for outdoor usage. Depending on such conditions as salt water and wind a cabinet in acid proof stainless steel (AISI316) can be supplied as an optional extra. In case sea water shall be used as flushing water the disposer can be delivered with salt water resistant inner parts.
Are there general tips for handling dried out food waste?
Before grinding dry food (like bread, steamed rice etc.), sticky food waste (like dough, pancakes etc.) and fibre food waste (like banana peels, leeks etc.) in the disposer it´s recommended to add water to the waste bucket, thereby dissolving the sticky food waste. It is also advantageous to mix the waste with other types of food waste. Permit continuous water supply to the disposer, and make sure of the required gradient for the drain line from the disposer, to ensure that this type of waste effectively will flow in the drain line.
How is the flushing water regulated?
A solenoid valve connected into the flushing water pipe opens the flow of water to a nozzle when the control circuit is activated by pressing the start button. The solenoid coil has therefore the same voltage as the control voltage of the disposer. When the operation of the disposer is completed and the stop button is pressed, then the solenoid valve closes and no water flushes through the disposer.
