Enviro-Tech ET3-R Urinal Flush Valve
Product Using Instructions
- Attention: Hold the plug not the wire to connect and disconnect and make sure the pins align to the holes in the right position.
- Note: Ceiling must be level. If ceiling is sloping/pitched, the detection zone will be altered.
- Follow the steps provided in the manual to install the sensor properly.
- Detailed instructions on how to connect the cables for Solenoid Valve, Sensor, and Transformer are provided in the manual.
- The manual includes information on adjusting settings like distance sensitivity, flush time, pre-flush settings, and more.
INSTALLATION INSTRUCTIONS ET-3R URINAL FLUSH VALVE
- We strongly recommend that you use a qualified and registered plumber and electrician.
- You must ensure that all pipe work is flushed adequately, particularly in new builds or where lines have been disrupted.
- Components of sensor products are particularly susceptible to debris and will require more thorough flushing than a standard plumbing fixture.
- IMPORTANT: Flush pipe must be DN20 copper pipe or equivalent. Installation must be in accordance with AS/NZS3500.
- Please note that – incorrect installation is NOT covered by your warranty

COMPONENTS
ATTENTION:
- Hold the plug not the wire to connect and disconnect and make sure the pins align to the holes in the right position.
SOLENOID VALVE INSTALLATION
- Flush Pipework thoroughly – failure to do so will result in solenoid sticking soon after install, which is NOT covered by your product warranty.
- Attach bracket, then insert solenoid valve.
- Connect water feed to inlet valve.
- Connect outlet to urinal.
SENSOR INSTALLATION
Note: Ceiling must be level. If ceiling is sloping/pitched the detection zone will be altered.
For Single Urinals
- Drill a 70mm hole in the ceiling centred on the urinal and 100mm from the wall/back of urinal to the centre of the sensor.
- Remove the screws from the sensor plate and install the flush box into the ceiling using the screw clips. (Ensure the screw holes are aligned as shown in 3)
- First make any changes required to flush time or pre-flush settings. Then refix the sensor plate using the 2 screws. Ensure sensor plate screws are parallel to wall for a single urinal.
For Twin or Trough Urinals
- Drill a 70mm hole in the ceiling centred on the trough or the 2 individual urinals and 300mm from the wall/back of urinal to the centre of the sensor.
- Remove the screws from the sensor plate and install the flush box into the ceiling using the screw clips. (Ensure the screw holes are aligned as shown in 3)
- First make any changes required to flush time or pre-flush settings. Then refix the sensor plate using the 2 screws. Ensure sensor plate screws are aligned facing the wall for twin or trough urinals.
CABLE CONNECTIONS
CABLE CONNECTIONS OF ET3-R
- Insert and connect male to male connection cable between sensor and solenoid (Fig 1)
- Connect sensor to transformer with WAGO connectors. Ensure marked taped ends go together in one connector, unmarked ends into the other (Fig 1).
- Lock WAGO connectors and then connect transformer to mains power (Fig 2). System will run test and be ready to use.
SETTINGS
DISTANCE
- Turn the potentiometer clockwise to increase the sensing distance and anti-clockwise to decrease it.
FACTORY SETTINGS
- Pre-flush is “‘ON”.
- Time is “4”.
- “1-10 Jumper Right” at 350kPa, giving flush volume of 0.8ltr for a single urinal.
PRE-FLUSH ON/OFF
- Factory setting is set to ‘ON’ and jumper is set to the ‘Right’.
- To turn ‘OFF’ pre-flush, set the jumper to the ‘Left’.
FULL FLUSH TIME
- Set the jumper to the ‘Left’ to choose 11-20s (20s=0s).
- Set the jumper to the ‘Right’ to choose 1-10s (10s=0s).
- Set the coding wheel to the required flush time – see table on next page for full details of flush volumes, and time setting options for different urinal types.

TROUBLESHOOTING
| PROBLEM | POSSIBLE CAUSE | SOLUTION |
| No water out or will not stop running | Most common: Plugs not connected correctly. No water supply or No Power. | · Check water and power supply. · Unplug all cables, leave unplugged for 5 minutes, then reconnect everything carefully. |
| Blocked filter or solenoid | Clean filter. Clean/replace solenoid. | |
| Too little water flow | Water pressure is low or turned down. | Adjust/raise the water pressure. |
| Flow Valve needs adjusting. | Adjust flow valve on solenoid | |
| The filter or solenoid is blocked. | Clean the filter. Clean/replace the solenoid | |
| Too much water flow | Water pressure is too high. | Adjust/lower the water pressure. |
| Flow valve needs adjusting. | Adjust flow valve on solenoid. | |
| Flush time or sensing distance is not adequate | Sensor requires adjustment. | See the ‘Settings’ section of this manual for instructions. |
