SPL Supreme Master Flush Urinal Water Control Instruction Manual

SPL Supreme Master Flush Urinal Water Control Instruction Manual

General Information

• Designed for indoor use only. Do not expose to the elements of nature.
• All plumbing connections must be made in accordance with AS/NZ3500 and installation with AS/NZ3500.2.
• Master Flush systems should be installed in compliance with all local / national water supply standards.

Warnings

• Read all instructions before attempting to install this system. It is recommended a qualified & registered plumber completes the install.
• Never connect the battery pack directly to solenoid valve.
• Ensure pipe work is thoroughly flushed before installing the solenoid assembly. Solenoid components are susceptible to debris and require additional flushing compared to a standard plumbing fixture.
• Consideration should be given to any regulations relating to an air gap, an air break or double check valve to protect against back flow.

Operating Instructions and Parts Manual

Please read carefully before attempting to assemble, install, operate or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage. Retain instructions for future reference.

Supreme Master Flush Urinal Water Control

Passive infrared (PIR) sensors detects and responds to movement engaging flush cycle. Program your flush cycles to suit system and traffic. Suitable for direct feed or cistern feed urinals. Battery or mains powered options.

Specifications

Planning

The Supreme Master Flush is suitable for controlling the water flow in direct feed or cistern feed urinals.
Consideration should be given to any regulations relating to an air gap, an air break or double check valve to protect against back flow.

Maintenance

• Keep slot opening on sensor clean and clear of dirt. Never use abrasive cleaners. Use warm soapy water and a soft cloth. Never hose or spray.
• To avoid premature failure it is recommended that the battery pack and solenoid is inspected and cleaned annually.

Typical Piping Arrangements

Typical Installation with Cistern Feed

Typical Installation with Direct Feed

NOTE: Multiple water outlets may require form of water balancing to achieve uniform flushing.

Installation

1. Solenoid (Cistern & Direct Feed)
   i. Isolate water supply. An isolating valve must be installed in accordance with AS/NZ 3500.1
   ii. Identify a suitable position for the solenoid assembly. Position in an upright position (preferably). If cistern, position solenoid as close to cistern as possible.
   iii. Cut the water supply pipe and flush thoroughly to purge swarf and debris.
   Failure to perform this step may cause the solenoid to become blocked and it will not close.
   iv. Ensure solenoid valve orientation is correct (flow direction is marked on the body of the valve with an arrow).
   v. Fix appropriately to wall or in ceiling cavity.
   
   vi. If direct feed urinal, fit air break at the top of the urinal spurge pipe.
   vii. Turn water on and check for leaks.

IMPORTANT:

• If water pressure exceeds 500KPA or 5bar, install flow restricter valve (not supplied). Flow restricter valve must be installed between the isolating valve and solenoid valve.

• If any water hammering present, install hammering arrestor (not supplied).
  Continued hammering may cause the solenoid to fail and bounce open.

• If solenoid is blocked due to debris and cannot close, check and clean filter.

• If water quality is poor, additional filter protection may be required.

• Cistern – ensure flush triggering level of autosyphon is below water inlet – Fig 1.
  – an air-gap must be present between the cistern water level and the water inlet pipe to prevent back-flow – Fig 1.

2. Sensor (Surface Mounted)

i. The sensor can be ceiling (preferable) or wall mounted. For optimal performance sensor should be positioned 1 – 1.5m from the urinal (allow traffic to pass through versus standing under)

ii. For single stall urinal position sensor above centre of stall.
iii. For double or triple urinal position in centre of stalls.
iv. If more than 3 urinals, use additional sensors.
v. When a suitable location has been found, remove mounting plate from sensor unit (magnetic) and fix to ceiling (or wall) using appropriate fixing for substrate. Take note of sensor slot orientation – Fig 3 & Fig 4.

NOTES:

• If mounting on wall ensure sensor slot is orientated North / South. It can also be tilted to capture a greater range of heights – Fig 4.
• Avoid locating sensor near heat sources (hot pipes, radiators, heat emitting lights or where direct sunlight encroaches on sensor lens).
• Additional flex (cable between sensor and solenoid) can be supplied upon request. DO NOT cut and join as polarity is critical to operation.

IMPORTANT:

• Never connect battery or power pack directly to the solenoid valve or until all plumbing connections are completed. Power must be connected last.

3. Connect Solenoid Valve to Sensor

i. Run the latching valve cable to the sensor. Ideally, this will be within the wall, ceiling cavity or in conduit.
ii. Do not extend the cable as this will affect correct operation (we can provide more flex if required).
iii. Once the power is connected, the system operates in default factory settings.

4. Connect Mains Power Supply (optional)

i. Locate battery holder and battery supplied with the system. If connected, remove the battery.
ii. Carefully align the power pack outlet cable plug to power inlet plug attached to the printed circuit board.
iii. Connect power pack to 220-240V 50/60Hz AC power supply (do not turn on).

Set up

1. Turn water on and inspect all connections. Start with isolating valve half open.
2. Separate the two halves of the sensor assembly by removing the 4 x self tapping screws.
3. Affix battery pack (or power pack if mains) to the back cover and pass solenoid lead through hole.
4. Connect the solenoid lead and battery to the printed circuit board (PCB) – Fig 5.
5. Program flush cycle. See page 8 for further details.
6. Reassemble the controller.
7. Attach to ceiling plate via back plate magnets.

Programming Flush Cycles

Direct Feed Urinals

1. Set the pre-flush to “2” (jumpers hard left) – See page 9.
2. Select time delay before flush. We suggest 1 minute.
3. Select janitor flush time (either 6 or 12 hours).
4. PUSH & RELEASE the learn button to start flow of water (green LED flash).
5. When sufficient water has flowed to clear the urinal PUSH & RELEASE the learn button again to stop the water flowing (red LED flash).
6. Your flush cycle is now set.

IMPORTANT: The flushing volume of water should not exceed the volume the sparge pipe (and urinal) can flush to avoid flooding during fault and / or blockages.

Cistern Feed Urinals

It has been assumed that the cistern will be fitted with an auto syphon.

1. Set the pre-flush to “0” (jumpers hard right) – See page 9.
2. Select a time delay before flush. Options range from 25 sec to 15 min.
3. Select janitor flush time (either 6 or 12 hours).
4. With the cistern empty, PUSH & RELEASE the learn button to start flow of water (green LED flash).
5. Continue filling until the auto syphon system starts to flush. Count 1001, 1002,1003 then PUSH & RELEASE the learn button again to stop the water flow (red LED flash). The fill cycle should over-run the flush by a few seconds to allow for pressure fluctuations.
6. Your flush cycle is now set.

IMPORTANT:

• You should not have a volume of water entering the cistern greater than the sparge pipe (and urinal) can flush. This is to safeguard against a possible overflow of the cistern under fault conditions.
• With cistern set up, sensor will not flash on detection and will flash once choosen delay period has past and solenoid opens.
• The maximum available flush time is 7 minutes.

Explanation of Master Flush Features

The controller has a number of features to allow customisation

Troubleshooting

There are 3 generation models of Supreme Master Flush. If spare parts are required visit splwashrooms.co.nz/product/flush- parts

Advanced Problem Solving

When the learn button is pushed and released (to open and close the valve) the LED’s at the sensor and the solenoid valve should flash simultaneously.

• If the both LED’s flash and you can hear the solenoid trying to shut or click – ensure there is water at the source and the solenoid is clear of debris. If this fails to resolve – replace solenoid valve.
• If the LED flashes at the sensor, but not the solenoid valve – check connection and cable between sensor and solenoid, including polarity. If this fails to resolve – replace solenoid valve.
• If there is no LED flash at the sensor – ensure there is power, all connections are correct and no signs of corrosion. If this fails to resolve – replace the printed circuit board (PCB).
