Installation of internal valve tap

NOTE:
Flush pipework prior to installation. Do not install opposite a mirror. Minimum 0.5 Bar dynamic pressure.When installing the inlet pipework, it is good plumbing practice to ensure that there is an accessible isolating valve upstream of the tap.The tap can be mounted on any horizontal surface up to 40mm thick. It requires a hole of 32.5-36mm diameter.

How to change the nozzle
Use the nozzle tool to unscrew the 5 litre (blue) nozzle. Insert the 3.5 litre (blue) nozzle and tighten until flush with tap body; no part should be protruding from the end of the tap. Ensure the nozzle is not over-tightened as this may pinch the “O” ring and cause the tap to leak.

Installation of external valve tap

NOTE:
Flush pipework prior to installation. Do not install opposite a mirror. Minimum 0.5 Bar dynamic pressure. The tap can be mounted on any horizontal surface up to 40mm thick. It requires a hole of 32.5-36mm diameter.

How to change the nozzle
Use the nozzle tool to unscrew the 5 litre (blue) nozzle. Insert the 3.5 litre (blue) nozzle and tighten until flush with tap body; no part should be protruding from the end of the tap. Ensure the nozzle is not over-tightened as this may pinch the “O” ring and cause the tap to leak.

Power connections

NOTE:
Only one power source should be connected at any time, either mains or batteries. It is not possible to connect both simultaneously.

If using the battery case, open it and fit 4 Alkaline AA (LR-6) batteries as indicated. Reseal and fasten into place on panel using screws A or with the sticky pads.
If using the mains adapter, fasten into place on panel in a dry location using screws A or with the sticky pads and connect the un-terminated mains cable to a 50Hz 230V AC single phase supply via a 1A fused spur (not supplied).
Electrical connection
Connect the power connector from the tap to the mains adapter, or in the case of a battery powered installation, the battery case.

• Decreases setting
• Increases setting
• Checks the setting being altered
• Saves changes and exits ICU configuration mode Quits ICU configuration mode without saving changes Configures sensor range
• Configures run-on time

Inserting and replacing batteries
The ICU uses 2 AAA or LR03 alkaline batteries, these must be installed before use. Always use new batteries of the same type. Install as indicated in the battery compartment on the rear of the ICU.

NOTE: Batteries should be replaced when the signal of the ICU becomes weak and it becomes difficult to activate either cleaning or configuration mode.

Activating cleaning mode
Cleaning mode, disables normal operation for cleaning for a timed 30 seconds. In order to activate cleaning mode with the ICU, it must be pointed at the sensor of the selected washroom product. Activation is most effective when the clean button is held down as the ICU is brought close to the sensor. It can take up to 3 seconds for the product to sense the ICU. When the washroom product is in Clean Mode, the sensor flashes green once a second.

Activating ICU configuration mode
In order to activate ICU configuration mode with the ICU, it must be pointed at the sensor of the selected washroom product. Activation is most effective when the configuration button is held down as the ICU is brought close to the sensor. It can take up to 3 seconds for the product to sense the ICU. The washroom product will return to normal operation if there are no button presses for 30 seconds.
Infrared taps
The ICU can adjust/activate the sensor range, the run-on time and the 12hr hygiene cycle settings. The product must always be put into ICU configuration mode before any setting can be configured.

Configuring sensor range
Point the ICU at the sensor and press the 1 sensor range button (the sensor blinks green). Decrease or increase the sensor range by pressing the and buttons respectively. The sensor blinks red when the min or max value is reached. Press the button to check the sensor range setting – the sensor displays the current setting by flashing green, see table.

Save setting and exit ICU configuration mode by pressing the button. Exit without saving by pressing the button.

Configuring run-on time
Point the ICU at the sensor and press the 4 run-on time button (the sensor blinks green).Decrease or increase the run-on time by pressing the and buttons respectively. The sensor blinks red when the min or max value is reached. Press the button to check the run-on time setting – the sensor displays the current setting by flashing green, see table.

Save setting and exit ICU configuration code by pressing the button. Exit without saving by pressing the button.

Configuring the 12hr hygiene rinse cycle
Point the ICU at the sensor and press the 5 12hr hygiene rinse button (the sensor blinks green). Decrease or increase the hygiene rinse time by pressing the and buttons respectively. The sensor blinks red when the min or max value is reached. Press the button to check the hygiene rinse time setting – the sensor displays the current setting by flashing green, see table.

Save setting and exit ICU configuration mode by pressing the button. Exit without saving by pressing the button.

Reset to factory settings
Point the ICU at the sensor and press the 9 reset button (the sensor blinks green). This sets all settings to the default factory settings. Save setting and exit ICU configuration mode by pressing the button. Exit without saving by pressing the button.

Cistermiser range

Urinal flushing

• Hydraulic Valve
  An automatic urinal flush control valve which reduces water consumption. The valve uses a simple patented mechanism which prevents water waste by ensuring that the auto-flush cistern is only filled, and can only flush, when the washroom is used.

• Infrared Control (IRC) Valve
  This valve automatically manages the water supply to the urinal cistern and reduces water consumption by up to 80%. The PIR sensor detects movement and activates the solenoid valve, allowing water into a urinal cistern.

• Direct Flush Valve
  An infrared sensor controlled urinal valve. It automatically flushes individual urinals after use, ensuring the highest level of hygiene from the minimum volume of water.

WC flushing

• Easyflush Wave
  An infrared, hands-free and water-conserving WC cistern flush valve suitable for concealed or exposed cisterns. Easy to install in retrofits or new installations, its no-touch dual flush WC cistern valve promotes water economy and hygiene in domestic and commercial washrooms.

• Easyflush Walkaway
  An infrared controlled automatic WC cistern flush valve that is suitable for concealed cisterns. The valve flushes once the user exits the cubicle. Ideal for use in environments where hygiene and water economy are concerns.

• Easyflush Direct
  An infrared electronic flushing system that removes the need for a WC cistern by taking its water feed straight from the mains supply. Ideal for high traffic areas as the system allows for a second flush without a delay.

Infrared Taps

• Novatap
  A contemporary deck-mounted chrome tap. The infrared control reduces water and energy usage and eliminates the risk that the tap may be left running.

• Vectatap
  An elegantly designed infrared tap with the benefit of hygienic hands-free operation. Vectatap improves water and energy efficiency and includes auto- shut off and hygiene flush features.

Washroom control systems

• Sensazone
  An innovative system to conserve water and energy. Occupancy is monitored by sensors; when someone enters the washroom all services controlled by Sensazone are activated – the hot and cold water, lighting and extractor fans.

• LinkThru
  LinkThru TMU delivers remote real-time monito ring of water temperatures on a 24/7 basis. LinkThru TMU harnesses the power of the Internet of Things to monitor water temperatures and helps to ensure Building Ow ner compliance with HSG274, reducing the risk of Legionella.
