Installation Instructions : Flushsaver Urinal

 
technical specificationsInstallation Instructions
 

 

The standard unit for a FlushSaver Urinal unit comprises one 24 volt A.C. Adapter, one Control Unit (includes sensor), one 24 volt solenoid valve, one air-gap valve and one 2m length of two core cable.

  1. PLACEMENT OF THE CONTROL UNIT.
    The Control Unit houses the microwave based movement sensor and the timing/solenoid activation circuitry. Ideally, the Control Unit should be mounted in the ceiling cavity positioned centrally and parallel to the urinal face. This type of mounting is suitable only where the microwave field can pass through the ceiling material. Suitable ceiling materials include plasterboard, Stammit or similar types of suspended material - concrete and steel are NOT suitable. In addition the mounting position should be no more than 4 metres from ground level. In cases where the ceiling construction incorporates metal, thick masonry or steel the Control Module can be mounted outside the ceiling in a security box. Source of the power supply should be considered when positioning the Control Unit.
    Adjustments can be made at the Control Module to change the operation of the units as follows;

  1. Flush duration – refer to settings on page 3

  2. The Microwave sensing field – refer to settings on page 3

  3. Lockout duration – refer to settings on page 3

  4. Control Module should not be placed on metal or Electronic Cabling
    Please note that these controls are delicate.

POWER SUPPLY.
A standard mains power point is required within 3 metres of the Control Unit. The A.C. Adapter is connected to the Control Unit at the positions marked “AC” on the unit. Do not turn the power on until installation procedures have been completed. All wiring should be in conduit.

SOLENOID VALVE.
The Solenoid Valve should be fitted in the water supply line taking notice of the flow director indicator on the Solenoid Valve. The Solenoid Valve is connected to the Control Unit at the points marked “Sol 1” – one wire from the Solenoid Vale into each connection. If it is a “double Urinal unit” the second Solenoid Vales is connected as above into “Sol 2”.

NOTE:

  • All FlushSaver parts should be fitted out of sight or at least out of reach of the customers for reasons of aesthetics and vandalism. If the Solenoid Valve or Control Module is exposed we recommend a security box for these items and all wiring in conduit.

  • Solenoid Valves must be fitted with disconnection unions either side of the Valve to allow maintenance

When the power is turned on the Red L.E.D. (Sensor Indicator) in the Control Unit will illuminate indicating initial operation and it will flicker momentarily then go out. The Green L.E.D.’s (Outputs 1 and 2) will be flashing at 1 second interval and a flush cycle will commence after 60 seconds. Green L.E.D’s will be on during flush. When the flush has completed, the Red L.E.D. will flash for the set lockout period. During this time, flush function is disabled. Any movement within the micro wave field (approx. 2m-3m from the urinal will cause the Red L.E.D. to illuminate indicating that movement has been sensed by the Control Unit.
The sensitivity of detection by the unit can be adjusted. A very fine watchmaker’s standard blade screwdriver should be used for adjustment, i.e. Position “0” most sensitive and “9” least sensitive.

Torx Slot/Drive heads are used to open the Valves to clean – Available from Blackwoods

Solenoid Coverage:
One Solenoid Valve will flush 3-4 Wall hung Urinals or 2.4 metres of slab.
For dual cisterns urinals a single Control unit can be employed where it is mounted centrally and the urinal is less than 4.8m wide. For dual cistern simply duplicate the solenoid valve connections for each cistern.
NOTE: Not more than two Solenoids should be run off one Control Unit.

IN-LINE FILTER:
It is recommended that an in-line filter be placed after the stop- cock to prevent water contaminants from entering the Solenoid Valve and unseating the valves diaphragm.

PRESSURE REDUCTION VALVE:
In installations where there is high water pressure and flow rates the stop- cock may have to be partially closed to prevent water escaping from the Air Gap. This causes water turbulence that often results in a noisy installation. Should this be the case a set pressure reduction valve (350-500KPA) should be placed in the water line – where it is a multi storey facility – one per floor is required.

Existing Cisterns:
The cisterns are removed and the Direct Mains system is used – one Solenoid Valve replaces each cistern being replaced.

NOTE: Care should be taken installing the Air Gap as Follows

  1. Ensure that the Solenoid Valve and Air Gap are vertically aligned with the flush pipe.

  2. Ensure that the Air Gap is installed such that all of the 40mm thread is inside the female coupling.

  • It is recommended 40mm sparge pipe for a minimum of 300mm from the Air Gap – then reduce to 19mm or 13mm.

  • Connection onto the Air-gap Valve thread should be with a 40mm F.I. coupling (no.2) PVC or Copper F I brazing bush. Do not use 40mm Cap and Linings.

PLEASE NOTE:
Ensure that the water line is flushed of any rubbish before the Solenoid Valves are connected to ensure that nothing gets caught in the Valves to stop them closing correctly. Should they fail to close correctly the Valves should be checked and cleaned.

IN-LINE FILTER:
It is recommended that an in-line filter be placed after the stopcock to prevent water contaminants from entering the Solenoid Valve and unseating the valves diaphragm.
