Warning:
The safety rules listed in this document must be obeyed. If you violate them unacceptable risks
may result.
The maintenance engineer must be fully aware of the complete contents of the operating and
maintenance instructions.
Warning:
Any modifications to the unit will cause the invalidation of the CE certification. Hazardous
situations may arise.
2.4 Safety instructions
The machine meets the basic health and safety requirements of the relevant directives of the European
Union. Improper or careless use can lead to dangerous situations.
Be aware of dangerous situations!
Please observe the following general safety instructions:
Connect the machine in accordance with the basic health and safety requirements of the
relevant European directives.
Exercise caution with loose hair and clothing.
Keep your hands away from dangerous zones.
Never power up the machine if people are in contact with it.
Electrical isolate the machine before carrying out maintenance work on the machine.
Faultysafety equipment must be replaced before the machine is used in production.
The machine must be maintained in accordance with the instructions found in chapter 6
Changes to the machine must not be implemented without the prior consent of the
manufacturer.
The safety equipment of the machine must be checked weeklyfor correct operation.
Do not remove or cover any labels on the machine
The unit is suitable for indoor use only.
2.5 Positioning of the units
Position the installation in such a way that the pathway for the operator and the service engineer is
sufficiently wide. These pathways must not be obstructed byequipment which can cause dangerous
situations for the personnel; this is important with respect to escape routes. For service propose it is
necessary to have enough space to access the right side of the machine to remove the side panel and
repair/replace components.
2.6 Safety precautions
The following primary precautions features are integrated:
All units have a main switch to turn off all energy to the unit to stop the process at once.
The main switch on each unit can be locked out in case of maintenance to prevent uncontrolled
start of the units.
The Solus is equipped with a safetygrid and lid which prevents access to the rotating parts of
the food waste grinder.
A safetycontact prevents the Solus to start in case the grid has been removed.
The rotaryblade stops automatically if the safety grid is removed during operation.

DATE : 19TH DECEMBER 2014
The unit is delivered with a CE-2A certificate.
There are rotating parts at the outlet of the dewater unit. To prevent access to these rotating
parts the collection bin must be in place. Therefore the unit has a bin detection. If the bin is not
in place the unit will not start. If the bin is removed during operating, the machine willstop
instantly. There is sign indicating the risk.
2.7 Hygiene
Good hygiene is very important. Please adhere to the following rules as guideline:
Clean the waste station at least once a day.
Use cleaning and disinfecting agents to ensure an optimum result (cleaning agent should not
affect Stainless steel 304, NBR, PVC or EPDM components of the drop unit).
Cleaning procedures of the Solus should be integrated in the existing hygiene plan of the site.
The Solus has a cleaning cycle option to clean internal wet parts and piping. We recommend using this
option at least once a day to prevent buildup of fogs and oils. You can contact Rendisk for additional
solutions to keep the machine in a proper condition.
! The operator always remains responsible for good hygiene.
2.8 Noise
The A-weighted equivalent continuous noise level on the workstations is below80 dB (A) during normal
operation. Higher noise levels may occur at the installation site due to local conditions. In this case, the
employer is obligated to provide operating personnel with appropriate protective equipment.
2.9 Water supply
Check local requirements if the Solus is connected to a drinking water network. If the Solus is
connected to a drinking water network in Europe there needs to be back flow preventer installed which
meets EN1717class 5.
The water which comes from the cleaning shower is not suitable for drinking.
2.10 Wastewater
The system dewaters the food waste. The waste water can be drained to the sewer. Check local
regulations for additional grease trap or other requirements.
2.11 Personal protective equipment
For normal operation (waste station) we advise the operator to wearfollowing personal protection:
Hand protection for hygiene (one way gloves)
Protective clothing against water
Safetyshoes. Be aware of slippery floor.
Ear protection in case noise levelincreases above 80dB.
For cleaning and maintenance:
Hand protection for hygiene (one way gloves) in case of working at food waste contact parts.
Protective clothing against water

Chapter 3 Machine description
This chapter gives general information about the Solus
3.1 Purpose of the unit
The unit is designed for the dispose of food waste (organic material only) in a hygienic and ergonomic
way at the source (restaurant or kitchen) with a minimum of logistics and handling of personnel to the
waste storage room.
3.2 Technical specification
The Solus is a standalone unit which reduces the volume of the loaded foodwaste on the spot. The food
waste is loaded on the grid where it falls through. Below the grid is a grinder which reduces the size of
the particles in the food waste. From here the food waste is transported to a dewater unit where the
water is separated from the solid parts. The water is partly recycled and the solids are collected in a bin.
The system consist the following parts:

3.3 Solus main components
After opening the cover (2), the waste can be dropped into the waste inlet and safety grid (1). The waste
falls on the grinder. After closing the safety grid and cover the cycle can be started bypressing the start
button on the control panel (5). Some water will be added to the food waste (3). The food waste will be
grinded and transported to the dewater unit. The hand shower can be used for cleaning the station (6).

3.3.1 Food waste intake
The maximum intake for each cycle is 16 liters. If more waste is added the water will float through the
overflowopening (1). The food waste inlet is covered with a safety grid (2) which prevents a human arm
to reach into the grinder (5). On the safety grid there are hit bars (3) to easy emptya plate (only one
hand needed). The grid also functions as a guide for the food waste to slide along the optional magnet
(4) which is situated at the far inside of the food waste inlet. This magnet will hold cutlery (metal) to
prevent the system against damage. There is a safety sensor (reed contact) (7) which detects if the
safetygrid is closed before starting a cycle.

4.4 Normal operation mode
4.4.1 Start-up
1. Turn on the main power switch on the Solus. The system automatically starts up in normal
operation mode.
 The status of the system can be checked on the control panel.
2. Check the collecting bin and replace/empty if necessary.
3. The system is ready for use.
4.4.2 Loading food waste intake
Do not throw cutlery, plastic, glass, rope or any other garbage that is not food waste (organic)
into the drop unit. This can damage the system and will reduce the lifetime.
Do not throw coffee grounds or frying fat/oil into the drop unit. This can lead to blockade of the
piping or dewater unit.
Do not overload the Solus.
Do not throw food waste with a temperature above 60°C in the drop unit.
Warning: Processing of meet ropes, plastic nets, fish nets or other typical fiber materials are
strictly prohibited because it can cause serious damage to the machine.

Figure 9 Materials that can (not) be processed with Solus
The following actions have to be carried out to process the food waste correctly:
Remove cutlery, plastic, coffee grounds or any other waste that is not food waste (organic) from the
trash. Also see figure 10.
1. Open the lid.

3. Close the safety grid (and the cover)
4. Start the cycle.
4.4.3 Batch cycle
If the push button ‘Batch cycle’ (Switch 1) is pressed once the Solus will start a batch to empty the food
waste intake (max 16 liters). The led will indicate that the cycle is running. If the button is pressed once
during the batch, the Solus will stop the running cycle instantly and return to standbymode.
