Discharge Of Reverse Rinsing Water; Reverse Rinsing - Honeywell F76S Instrucciones De Montaje

7.3 Discharge of reverse rinsing water

The reverse rinsing water must be routed to the drain channel
in such a way that no backwater can occur.
To do this there are 3 options:
1. Direct connection:
o Connector DN 50/70 as well as the necessary pipes and
siphon (3 elbows 90°) in DN 70.
2. Drain free to existing floor drain.
3. Drain into open container.
Filter size Reverse rinsing volume*
1/2" and 3/4" 12 Liter
1" and 1 1/4" 15 Liter
1 1/2" and 2" 18 Liter
*at 4 bar inlet pressure and 3 x 3 seconds reverse rinsing

8. Commissioning

8.1 Reverse rinsing

During reverse rinsing, an inlet pressure of at least 1.5 bar is
required. The reverse rinsing interval depends on the degree
of dirt in the water. At the latest every 2 months, reverse
rinsing should be carried out according to DIN 1988, Part 8.
To ensure convenient and regular adherence to the reverse
rinsing interval, we recommend installing an automated
reverse rinsing system Z11S.
Filtered water can also be tapped during reverse
rinsing.
8.1.1 Manual reverse rinsing
If reverse rinsing water is not to be discharged via a direct
connection, a collecting container must be positioned
beneath before reverse rinsing.
1. Open ball valve by turning the reverse rinsing button to the
stop point
o Select bar must be upright
o The patented reverse rinsing system starts
o When filtering with Double Spin Technology, a visual
function check is possible through the rotating red rotor
2. Close ball valve again after approx. 3 seconds. Repeat
procedure three times
o If the filter is extremely dirty, the procedure may have to
be repeated additional times
With aid of the memory ring, the next deadline for manual
reverse rinsing can be booked.
8.1.2 Automatic reverse rinsing with the Z11S
The automated reverse rinsing system Z11S is available as
an accessory. The automated system reliably takes over
reverse rinsing of the filter at intervals which can be set
between 4 minutes and 3 months.

9. Maintenance
We recommend a planned maintenance contract
with an installation company
In accordance with DIN 1988, part 8, the following measures
must be taken:
9.1 Inspection / Servicing
9.1.1 Filter
Interval: every 2 months
• The filter must be cleaned by reverse rinsing regularly, at
the latest every 2 months
• Non-compliance can lead to the filter becoming blocked
This results in a drop in pressure and decreasing water
flow
• The filter meshes are made of stainless steel. A red
coating as a consequence of rust from the pipelines has no
influence on function or the way the filter works
Do not forget to do a visual check of the ball valve.
Replace if it is dripping!
9.2 Cleaning
Caution !
Do not use any cleaning agents containing solvents
and/or alcohol to clean the plastic parts!
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Unscrew filter bowl
o Use double ring wrench ZR10K
5. Remove filter, clean and reinsert
6. Place O-ring onto filter bowl
7. Screw in filter cup hand-tight (without tools)
8. Slowly open shutoff valve on inlet
9. Slowly open shutoff valve on outlet
10. Disposal
• Dezincification resistant brass housing
• Brass threaded connections
• Stainless steel fine filter
• Red-bronze or shock-resistant, clear transparent synthetic
material filter bowl
• NBR seals
Observe the local requirements regarding correct
waste recycling/disposal!
