3. Site Preparation

Please review the requirements outlined in this section before your Digester ships to your location.

Note

All work and costs associated with the site preparation phase are the responsibility of the customer.

3.1. Location

With guidance from the customer, BioHiTechManco recommends a location for the Digester that blends seamlessly into their current workflow and processes. Units are typically placed either at the food waste's point of generation, or its final point of collection.

Easy access to power, water, and drainage aids in determining a unit's location. Finding a location that has adequate and relatively easy access to power, water, and drainage helps minimize site preparation costs.

The location of the Digester should have a level surface.

The optimal space for the machine has at least 3 feet (1 meter) of clearance on both sides of the machine. The additional room is necessary to help facilitate maintenance of the machine.

Appropriate Clearance

Due to the weight and size of the machine, we strongly recommend that these criteria are met. In the event this space is not available, a customer application may be necessary.

See the chart below on the Digester's physical dimensions, based on the model.

    Eco-Safe 8 and 12 Water Connection

The following water requirements must be met:

  • A dedicated warm water source with a 3/4 inch male pipe fitting is also required within 6 feet (2 meters) of the left side of the machine.

  • Incoming water pressure should be a minimum of 50 PSI (3.5 bars) at 4 gallons (15 liters) per minute.

  • The water source should provide water at 90° to 110° F (32° to 43° C). 
 Some customers may choose to use a mixing valve and a thermometer to ensure a proper temperature.

    Water Mixing Valve

  • The water source should be dedicated to machine operation only. Sharing the water source with other usage is not recommended.

3.4. Drainage

Proper drainage is essential for safe disposal of wastewater from the Digester into the sewer system.

The following drainage requirement must be met:

  • The drain must be an open floor drain and should be connected to the Digester with a minimum 2-inch drain pipe (PVC or Copper). Please minimize any changes in flow direction from the machine to the drain hole. 


    Typical floor drain

  • An elbow fitting should not be used more than 2 times. 


  • A pitch must be maintained at least 1/4-inch declination for every 2 feet length. 


  • If processing large amounts of meat and dairy products, a grease interceptor should be considered. 


4. Installation

4.1. Installation Procedure

The following procedure is used to install the Eco-Safe Digester:

  1. Place the Digester in its desired location. Lower the legs.

  2. Connect the power lines into the Digester.

  3. Power on the Digester. Perform a weight test.

  4. Connect the stainless steel drain elbow & PVC tubing as needed.

  5. Connect the warm water source to the Digester.

4.2. Fixed Legs

Roll the Digester to its desired location using its built-in wheels. The final location of the Digester should have a level surface.

  1. Use a bottle jack or pallet jack to raise unit off the floor to enable installation of the stationary legs.

  2. Install the legs. Use a wrench to screw the legs onto the Digester so that they are resting as high as they can go (screwed in all the way).

  3. Use the jack to lower the unit onto its legs. Remove the bottle jack or pallet jack.

  4. Check all four legs. Using a wrench, lower any legs that are not firmly planted on the ground.

For all units:

  1. Legs on both sides of machine must be adjusted all the way down.

    Check to make sure that the Digester is level. Do this by using a wrench to make sure that an equal amount of force is required to turn the screw under each leg. Use a level to ensure that the machine level left-to-right and front-to-back. When complete, lock down the lock nut to make sure it does not move due to vibration.

    Note

    DO NOT use the rocking technique to check to see if the Digester is balanced. There is way too much weight and inertia for this approach.

4.3. Electrical Connection

Note

Electrical connections vary by model and by country.

Please follow the appropriate instructions for your Digester model and your country.

All wiring work is performed inside of the electrical cabinet in the Digester. On all models, the electrical cabinet is located in the front of the unit, and is accessible after the front panels are removed. Note that a key is required to access the electrical cabinet.

Warning

All electrical work should be done with the electrical power turned off.

If you are in any way unsure of how to proceed with any of the procedures outlined in this manual, please consult a qualified and certified electrician to complete the electrical installation in accordance with the required standards and regulations or contact BioHiTech. Manco.
