  7. Pull out the flush hose.

    231208-Remove_flush_hose.eps
  8. Pull out the recirculation hose.

    Caution

    It is important that the circulation hose is pulled out from the top, to minimize the risk of the hose coupling getting stuck in the pipe.

    Note that the location of the Core varies depending on the customer's model. The connection pipe can be located on the right or left side of the Wall Box or in the back.

    231208_Cabinet_Remove_flush_hose.eps
  9. Pull out the sensor cable.

    231208-Remove_sensor_cable.eps

Install Sensor Tank

  1. Clean the drain unit.

    231211_clean_drain.eps
  2. Route the sensor cable from the Wall Box through the connection pipe with the large connector down to the Sensor Tank. Pull out the cable about 180 mm in the floor fitting.

    231211_sensor_cable_in_drain.eps
  3. Tape the flush hose and the recirculation hose together at the end of the couplings, flush hose on the left. Make sure that the couplings, especially the o-rings, are carefully covered with tape.

    231211-Tape_hoses.eps
  4. Pull the hoses through the connection pipe, with the couplings down towards the Sensor Tank. A tension spring is recommended for smooth installation.

    231211_Cabinet_Insert_recirc_and_flush_hose.eps
  5. Apply fitting grease and connect the hoses to the Sensor Tank dock.

    210302_SIT_connect_hoses_4.eps

    210302_SIT_connect_hoses_2_R3.eps
  7. Insert the dock into the connecting pipe and push it all the way in.

    210308_SIT_insert_sensor_lock.eps
  8. Lock the Sensor Tank dock in place with the spring lock. Ensure that the sensor cable is not pinched.

    210309_SIT_insert_sensor_lock_spring.eps
  9. Apply grease to the Sensor Tank o-rings.

    231220-Sensor_tank_oring.eps
  10. Remove the protective cap from the sensor cable, and connect the cable to the Sensor Tank.

    Caution

    Make sure to have correct alignment between the groove and the pin when connecting.

    210302_SIT_connect_cable.eps
  11. Insert the Sensor Tank to the drain unit.

    Caution

    Make sure the Sensor Tank is inserted correctly. Its edge should be fully pushed towards and at level with the edge of the drain unit.

    210430_SIT_insert_tank_lock.eps
  12. Lock the Sensor Tank in place by turning the Sensor Tank Lock 90° clockwise.

    240226-Lock_Sensor_Tank.eps
  13. Place the Funnel and grate back in place.

    Note

    Place the Funnel with the hole oriented to the left! Placing the hole oriented to the right will disable recirculation.

    240305-Insert_funnel_and_grid.eps
  14. Connect the sensor cable to the communication port on the Core (blue port). The connector should be tightened by hand.

    Caution

    Ensure correct alignment between the connector and communication port. This must be done with particular attention to prevent damage to the pins.

    231211-Connect_sensor_tank_to_core.eps
  15. Cut the circulation hose and the flushing hose according to the measurements below from the rubber grommet of the Wall Box, or from the connection pipe in the case of an installation with Basic, depending on the installation.

    211028_Hatch_core_cut_hoses.eps
  16. Apply fitting grease to the separate hose coupling, push all the way into the circulation hose and tighten with the hose clamp.

Install Core

Take the new Core out of the packaging and put it in a safe and stable place. Make sure that the packaging and pallet are saved in good condition - they should be reused when returning the replaced Core. Also, save the foam inserts to ensure that the Core can be sent back in a safe and stable way.

  1. Transfer the transport plugs from the new Core to the old one.

    231211-Transport_plugs.eps
  2. Place the new device in the Wall Box. The Core should click all the way into the vibration damper.

    231213-Cabinet_Insert_core.eps
  3. Attach the safety wire to the Core and keep it in the tilted position.

    231213_Cabinet_Hatch_Safety_Wire-2.eps
  4. Feed the stripped part of the electrical cable into the electrical box and tighten the strain relief.

    240305-Fasten_strain_relief_junction_box.eps
  5. Connect the cables and screw the lid back to the electrical box.

    240305_Hatch_Junction_Box.eps
  6. Lean back and screw the Core onto the vibration damper. Make sure the electrical cable is placed behind the hot water pipe without any sharp bends, and make sure it is not pinched behind the Core.

    231113_-_Hatch_Cabinet_Fasten_core_top.eps
  7. Open the Filter hatch and insert a Filter Capsule.

    210511_1-02-0045_R3_change_filter_3.eps
  8. Connect the hot and cold water connections. Then connect the shower water connection to the Core.

    Caution

    Make sure the gaskets are in good condition and have no damage.

    231213_-_Insert_Remove_water_connections.eps
  9. Connect the Wi-Fi antenna cable.

    231213_Cabinet_R3_Remove_wifi_cable.eps

    For Ethernet installation: Unscrew the protective cover and connect the Ethernet cable.

    231213-Connect_ethernet_cable.eps
  10. Apply fixture grease and connect the recirculation hose and flush hose to the Core.

    It is important to relubricate the plug-in coupling and hose to prevent damage to the o-ring in the connection on the Core.

    231211-Connect_recirculation_and_flush_hose.eps
  11. Unscrew the protective caps on the red and blue communication ports on the Core. Then plug in the Control Dial (red port) and Sensor Tank (blue port).

    For installations with Audio: Unscrew the protective cap on the yellow communication port and plug in the amplifier. The contacts should be tightened by hand, and the cable to the Control Dial and amplifier should be routed behind the air gap tank.

    Caution

    Ensure a proper alignment between the connector and the communication port. This must be done with special attention to prevent damage to the pins.

    231214-Connect_sensor_tank_control_dial_and_audio.eps
  12. Fit the protective caps on the old Core and place it in the packaging.

    231214-Add_protection_plugs.eps
  13. Turn on the incoming water. Check and fix any water leaks. Then turn on the power. It takes about 1 minute for Core to start up.

  14. Replace the air gap tank cover.

    210119_Remote_Cabinet_R3_core_air_gap_bracket.eps
  15. Put the splash guards back in the Wall Box and close the door.

    231211-Close_Hatch_Cabinet_and_remove_protection_sheets.eps
  16. Verify the shower. Follow the guide here.

  17. The replaced Core should be sent back to Orbital.

    • As per the instructions, make sure the plugs and protective caps are transferred from the new to the old Core.

    • Use the pallet, box, and foam inserts from the new Core to pack the old Core. Secure the box safely to the pallet using straps, tape, or similar.

    • Record the work order number on the label if it is not already there, and contact Orbital to book the pickup.
