Installation; Reverse Rinsing; Manual Reverse Rinsing; Automatic Reverse Rinsing With The Z 11 S - Honeywell Braukmann F76S Instrucciones De Instalación

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. Isolating valves
should be fitted on both sides of the water
supply unit.
1.1 Assembly
1. Flush pipework thoroughly.
2. Install water supply unit with filter
Ensure correct flow direction as
indicated by arrow
Install in horizopntal pipework with
filter bowl downwards
Install free of bending or twisting stress.
3. Seal in pressure gauge connection.
4. The water supply unit with filter is now
ready for use.
1.2 Reverse Rinsing Water Drainage
The reverse rinsing water must be piped to
the drain in such a way that no back
pressure can occur.
To ensure this, there are three possibilities:
1. Direct connection to drainage pipework
A DN 50/70 reducing connector and
required DN 70 tundish and pipe
(maximum three 90º bends).
2. Free discharge into existing floor drain
3. Discharge into an open container.

* at 4.0 bar inlet pressure and a rinse duration of 15
seconds

2. Reverse Rinsing

An inlet pressure of at least 1.5 bar is required
for reverse rinsing. The reverse rinsing interval
is dependent on the degree of contamination
of the water. DIN 1988, Part 8 requires that
the reverse rinsing interval shall be no longer
than every two months.
To ensure that convenient and regular reverse
rinsing takes place, we recommend that a
Z 11 S automatic reverse rinsing actuator be
fitted.
Water can still be drawn during the
reverse rinsing cycle.

2.1 Manual Reverse Rinsing

If reverse rinsing is not via a direct drainage
connection, then a suitable container must
first be put underneath.
1. Open the ball valve by turning the
reverse rinse knob 1 until it reaches
stops
Indicator bar must be vertical
The patented reverse rinsing system
will start operating.
2. Close the ball valve after approximately
15 seconds
A longer reverse rinsing period may be
necessary if the filter is very dirty.
The date of the next scheduled reverse rinsing
can be marked using the memory ring 2 .
2.2 Automatic Reverse Rinsing
with the Z 11 S
The Z 11 S automatic reverse rinsing actuator
is available as an accessory. The actuator
automatically controls reverse rinsing at any
preset interval between four minutes and
three months.

3. Maintenance
Wir empfehlen dem Betreiber, einen
Wartungsvertrag mit einem Installations-
unternehmen abzuschließen.
Planned maintenance is recommended and
DIN 1988, Part 8 specifies the following
operations:
The filter must be cleaned regularly by
reverse rinsing and at intervals of no
longer than two months. This
operation can be carried out by the
user.
Filter can become blocked if this is
not done, resulting in pressure drop
and falling flow rate.
The filter sieves are stainless steel.
Red rust deposits from the pipework
have no effect on function and filter
operation.

4. Scope of Application
