Installation

The SN4 071 installation must comply with local plumbing codes. All work to install the equipment, put it into service and carry out maintenance must be done by a qualified professional specialist.

Fixing bowl to the Floor

  • Draw the outline of the base on the floor, in the area around the fixing holes in the ceramic bowl.
  • Measure 1/2’’ from the outline drawn, position the brackets and drill through the middle of the holes.
  • Screw the brackets in place, leaving them loose, they will be tightened once the bowl has been fitted.

Fit the bowl

Note: wait until all the connections have been made before fixing the bowl definitively in place.

  • Fix SN4 071 securely using the screws provided.
  • Your mountings must be appropriate for the base on which the device is to be installed.

Evacuation

The discharge outlet has a non-return valve.

The discharge diameter is 38 mm.

Fitting the Control Panel

  • Select control panel location convenient to toilet.
  • The keyboard must be fitted in a position where it does not interfere with use of the seat and cover, and it must not be placed more than 4 ft from the control box.
  • Cut out a rectangle measuring 3’’x 2’’ from the bulkhead.
  • Fix the panel in a horizontal position and clip the frame into place.

Electrical Connections

The electricity supply to the SN4 071 must be connected directly to the electrical switchboard, and it must be used solely for that equipment. It is advisable to add a 25 A fuse in a 12 Volt system, and a 15 A fuse in a 24 Volt system.

Advice for wiring up

 

 

Electric Diameter Wire

 

 

12 V 24 V

1.5 mm2 = 3 ft 3 in max

2.5 mm2 = 6 ft 7 in max

4 mm2 = 9 ft 10 in max

6 mm2 = 14 ft 1 in max

1.5 mm2 = 11 ft 6 in max

2.5 mm2 = 19 ft 8 in max

4 mm2 = 31 ft 2 in max

6 mm2 = 45 ft 11 in max

Fitting the Control Box

  • Fix the control box in a dry, protected location.
  • Connect the cable from the control panel to the control box.
  • Insert and connect the electrical wiring from the SN4 071 to the electrical box.
  • Lastly, connect the electrical box to the battery, making sure that the cross-section of the wires is sufficient.

Connection of the tank sensors

Fitting: Sensors are provided with 14’’ cables. You can extend up to 15 ft; no specific wire is required.

Locate the location for the sensors using diagram 9 and the information below:

  • The Full Tank sensor should be placed at the minimum distance of «wall thickness + 50% of thickness» from the top edge.
  • The Mid-Tank sensor should be installed in the middle of the tank, both in height and width.
  • Clearance should be no less than 2’’.

Clean the surface of the tank. Firmly press the sensor on the tank to stick it in place.

IMPORTANT There can not be any metallic part or another water tank within the clearance section of each sensor. This can affect its sensitivity creating a false reading. There shouldn’t be another cable, sensor or any wire above our sensors.

Optional : you can use a second set of sensor. Please respect clearance between sensors.

Connection to the Control Box

Sensors are not polarized. Follow the wiring diagrams. Return wire has to be plugged on negative terminal of control box or on ground metal frame (ground continuity has to be checked first).

Use

SN4 071 must only be used for shredding and disposing of feces and toilet paper.

Only the disposal of toilet papers, fecal matter, and waste water will be under guarantee. Any damage due to foreign bodies such as cotton, condoms, sanitary towels, wet wipes food, hair, or liquids such as oils, solvent products,… will not be under guarantee.
