Installation - Honeywell Z 11 AS Einbauanleitung

1. Installation

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.
2. Assembly
2.1 Close isolating valves 1 and 2 .
2.2 Open the ball valve.
Check availability of a suitable drainage
outlet or catchment vessel.
2.3 Filter connection 1 / "- 1 1 / " (also 1 1 / " and 2"
2 4 2
manufactured 1995 and onwards)
Unscrew the ball valve 3 from the filter (whilst
restraining with the forked key SW 24)
Screw in the Z 11 AS with the sealing ring
provided
Screw existing drain connection or hose
connector into the Z 11 AS.

2.4 Filter connection sizes 1 / " and 2" (up to 1995):
2
Unscrew ball valve 3 from filter, whilst
restraining with a 24mm open-end wrench
Push and turn the ball valve on the Z 11 AS
by 180° so that the internal thread is towards
the filter
Screw in Z 11 AS using existing seal ring.
2.5 Flange filter sizes DN 65 to DN 100
Unscrew ball valve 3 from filter
Seal in the ball valve of the Z 11 AS with
suitable material (e.g. hemp)
Screw existing drain connection into Z 11 AS.
2.6 Insert electrical plug
This will cause a reverse rinsing cycle to
occur.
3. Reverse Rinsing Water Drainage
3.1 Direct Connection Connect drainage
according to DIN 1988 or to national standards.
Drainage connection must have a minimum
cross section 'A' as indicated in table below
to prevent overflow from the pipework.

When our drain connector is used, the free
20 mm discharge dimension required in
DIN 1988 is integral with the connector.
3.2 Discharge into existing floor drainage

4. 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.
4.1 Pull out the electrical mains plug.
4.2 Unscrew the housing screws and remove
the lid.
4.3 Insert the batteries (Four LR 6 - 1.5 V -
Mignon/AA size alkali-manganese).
4.4 Changes if necessary.
4.5 Reassemble in reverse order.
Do not leave the mains unplugged for too
long when batteries are fitted.
5. Setting of the Reverse Rinsing
Interval
DIN 1988 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 1 on
the housing cover
Press pushbutton 2 until the required
programme appears on display 3
Display 5 indicates the number of completed
reverse rinsing cycles. This number can be
reset by briefly pressing pushbutton 4 .
Service Indicator Displays
If programme pushbutton 2 and reset pushbutton 4
(for five seconds) are pushed at the same time, the
remaining time to the next timed reverse rinsing cycle
is indicated on 3 and display 5 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. Counter 5 can be reset to 0 by pressing
C reset button 4 .

Manual Actuation of the Reverse Rinsing
Reset - press pushbutton 4 for five seconds
Manual Reverse Rinsing when Electrical
Power is off
Push the housing against the ball valve and
400
towards the filter and turn the housing 90° anti-
clockwise. After approximately 15 seconds return
the housing to the original outlet position.

6. Additional connection options
6.1 Remote switching
The Z 11 AS can be remotely actuated by:
a) A volt-free switching circuit (e.g. Honeywell
Centra Bürkle type REL 2)
b) Via an open-collector output.
In both cases the minimium holding period is
one second. Reverse rinsing occurs when the
inputs "Start" and "U+" have been separated.
6.2 Remote monitoring
For remote monitoring of the open/closed position
of the ball valve the installation of a building
management system with 0 to 10V 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 5V and 6 V the ball valve is
closed.
6.3 Differential pressure switch
The reverse rinsing function can be actuated
according to demand using the DDS 76 differenti-
al 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" .
The DDS 76 differential pressure switch can
only be used where F 76 / F 76 S-F fine
filters are also installed.

According to regulations
With due regard to safety
7.2 Follow installation instructions
7.3 Immediately rectify any malfunctions which
may influence safety.
7.4 The Z 11 AS automatic reverse rinsing
actuator is exclusively for use in reverse
rinsing applications with Honeywell
Braukmann filters and filter combinations.
Any variation from this or other use will not
comply with requirements.
All electrical work must be carried out by
authorised specialists and comply with local
