Assembly

Installation Guidelines

It is necessary during installation to observe codes of good practice, to comply with local requirements and to follow the installation instructions. The installation location should be protected against frost and be easily accessible.

In case the mains supply fails during the backwash the batteries (if they are fitted) provide the energy for closing the backwash ball valve. The battery charge should be checked regularly. At the latest after two years exchange the batteries with new ones
In order to avoid flooding, it is recommended to arrange a permanent, professionally dimensioned wastewater connection

Assembly instructions

Close isolating valves
Open the ball valve
Check availability of a suitable drainage outlet or catchment vessel.
Filter connection 11/2″- 11/4″ (also 1/2″ and 2″ manufactured 1995 and onwards)
• Unscrew the ball valve from the filter (whilst restraining with the forked key SW 24)
• Screw in the Z11AS with the sealing ring provided
• Screw existing drain connection or hose connector into the Z11AS
Filter connection sizes 11/2“ and 2″ (up to 1995):
• Unscrew ball valve from filter, whilst restraining with a 24 mm open-end wrench
• Push and turn the ball valve on the Z11AS by 180° so that the internal thread is towards the filter
• Screw in Z11AS using existing seal ring5.
Flange filter sizes DN65 to DN100
• Unscrew ball valve from filter
• Seal in the ball valve of the Z11AS with suitable material (e.g. hemp)
• Screw existing drain connection into Z11AS
Insert electrical plug

Fitting Batteries and Fuses

The batteries provide a power supply to close the ball valve in compliance with regulations if the mains current fails during the reverse rinsing cycle.

Batteries are not supplied with the appliance.

Pull out the electrical mains plug
Unscrew the housing screws and remove the lid
Insert the batteries (Four LR 6 – 1.5 V – Mignon/AA size alkali-manganese)
Changes if necessary
Reassemble in reverse order

CAUTION!
Do not leave the mains unplugged for too long when batteries are fitted.

Start-up

5.1 Reverse Rinsing Water Drainage
1. Direct Connection Connect drainage according to EN 806-5 or to national standards

CAUTION!
Drainage connection must have a minimum cross-section ‘A’ as indicated in table below to prevent overflow from the pipework.

Filter size| Diameter size pipe A 1| Transition Connector B| Reverse Rinsing Quantity (litres2)| C mm
---|---|---|---|---
1/2″ + 3/4″| DN70| DN50/70| DN50/70 Approx.| 300
11″ + 1/4″| DN70| DN50/70| DN50/70 Approx.| 300
1 1/2″ + 2″| DN70| DN50/70| Approx. 18| 300
65-100| DN100| DNDN40/100| DN40/100| 400

*1 All necessary pipes and tundish (3 X 90o bends)

2 At 4.0 bar operating pressure and 25-second reverse rinsing duration

When our drain connector is used, the free 20 mm discharge dimension required in EN 806-5 is integral with the connector.

Discharge into existing floor drainage

Setting of the Reverse Rinsing Interval

EN 806-5 requires that a reverse rinsing cycle must occur at intervals of not more than two months. The time interval should be set according to the level of contamination present.

Setting of Other Intervals

Select required interval from the table on the housing cover

Press push button until the required programme appears on display
Display indicates the number of completed reverse rinsing cycles. This number can be reset by briefly pressing push button.

Service Indicator Displays

If programme pushbutton and reset pushbutton (for five seconds) are pushed at the same time, the remaining time to the next timed reverse rinsing cycle is indicated on and display will indicate the corresponding time interval between reverse rinsing cycles (0= minutes, 1 = hours and 2 = days).
After electrical power has failed, when it is restored a reverse rinsing cycle will automatically occur. The set timed programme and counter reading are retained. The counter can be reset to 0 by pressing reset button.

Manual Actuation of the Reverse Rinsing
Reset – press pushbutton for five seconds
Manual Reverse Rinsing when Electrical Power is off
Push the housing against the ball valve and towards the filter and turn the housing 90° anticlockwise. After approximately 15 seconds return the housing to the original outlet position.

Additional connection options

Remote switching

The Z11AS can be remotely actuated by:
a) A volt-free switching circuit
b) Via an open-collector output.
In both cases the minimum holding period is one second. Reverse rinsing occurs when the inputs “Start” and “U+” have been separated

Remote monitoring

For remote monitoring of the open/closed position of the ball valve the installation of a building management system with 0 to 10 V input is recommended. The maximum current is 10 mA. With a current of 0.5 V the ball valve is open and with a value between 5 V and 6 V the ball valve is closed.

Differential pressure switch

The reverse rinsing function can be actuated according to demand using the DDS76 differential pressure switch with voltage-free switching. It is recommended that the differential pressure be set to 1.0 bar. Operation occurs when the inputs “Start” and “U+” have been separated, that is, after the differential pressure has fallen below the set value. Through this it is guaranteed that a maximum quantity of water is available for reverse rinsing. If reverse rinsing starts immediately irrespective of the duration of the differential pressure signal, then the inputs should be connected instead to “U+” and “SIGN”.

CAUTION!
The DDS76 differential pressure switch can only be used where F76 / F76S / F76S-F fine filters are also installed.
