2. Sensor Tank & Misc.

This instruction shows how to swap the Sensor Tank with accessories in a remote installation (shower model Hatch LK, Hatch Cabinet, or Basic), where the Core is installed outside of the shower area. Follow the instructions in detail, and don't hesitate to reach out if you have any questions - support@orbital-systems.com.

Use the following kit to swap the Sensor Tank.

  7. Remove the spring lock and pull out the Sensor Tank dock.

    231208-Remove_spring_lock_and_sensor_dock.eps
  8. Remove the clip to release the hoses.

    231208-Remove_clip.eps
  9. Release the Sensor Tank dock.

    231208-Remove_sensor_dock.eps
  10. Pull out the flush hose.

    231208-Remove_flush_hose.eps
  11. 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.

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.

    240918_Basic_Insert_recirc_and_flush_hose_eps.eps
  5. Apply fitting grease and connect the hoses to the Sensor Tank dock.

  6. Lock the hoses using the clip. Press the clip down until it clicks.

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

    210507_Install_shower_Unit_Recirc_hose_barbed_nozzle.eps
  16. Apply fixture grease and connect the recirculation hose and flush hose to the Core.

    231211-Connect_recirculation_and_flush_hose.eps
  17. Turn on the power.

    231213-Turn_on_power.eps
  18. Start the shower to validate the Sensor Tank replacement. Set the temperature to 28°C. The shower should start recycling and show a count on the Control Dial within 5 minutes without increased noise level.

    231120_instruction_-_start_and_stop_adjust_temperature.eps
  19. Turn off the shower.

    231211_stop.eps
  20. Complete and submit the service report (found in the service request).

  21. Recycle the parts and components that should not be reused. 240516-Recycling.eps
