3.4 Connecting the water safety device
A water safety device (1) must be used in order for the softener to be
operated in accordance with DIN requirements. A kit is available
from Winterhalter for this purpose.
The kit contains a backflow preventer type HD in accordance with
DIN EN 1717.
Installation of the water safety device is shown in the drawing.
Should national guidelines not require a check valve or anti-vacuum
device, the water supply hose (2) is connected directly at the control
head (3).
3.5 Installing dirt trap
After the water stop cock (1),
install a dirt trap (2) with a
mesh width of 150 µm.
INFO
The dirt trap en-
closed with Win-
terhalter warewash-
ers is suitable for this
purpose.
Connect supply hose (3).
3.6 Connecting the waste water hose and overflow
hose
Attach waste water hose to the
hose nipple and secure with a
hose clamp.
Guide the waste water hose to
the on-site water drain.
Attach a hose to the safety
overflow on the rear of the sof-
tener and guide this to the on-
site water drain.
Attach both hoses to the water
drain at a distance of 20 mm
(see drawing).
4 Commissioning
After the machine has been correctly connected to the water supply
and waste water drain, contact your Winterhalter branch or your
dealer in order to request them to perform commissioning. You can
use this opportunity for you and your operating personnel to learn
how to operate the softener.
5 Operation
The softener works automatically following commissioning. Only the
regeneration salt must be refilled from time to time.
Caution
Possibility of damage due to incorrect salt.
Only use undenaturated evaporated salt (approx. 15 mm
granularity or in tablet form) marked as regeneration salt
for softeners. Do not use any other types of salt e.g.
table salt, rock salt or de-icing salt. These may contain
components that are not soluble in water.
Refill the regeneration salt as
soon as the water in the contain-
er is above the level of the salt.
6 Maintenance
Caution
Possibility of damage due to chemicals.
Do not clean the inside of the container with cleaning
agents or other chemicals.
Only ever clean the container with water.
Clean the outside of the softener using conventional plastic kitch-
en hygiene products.
7
Maintenance by service technicians
Have the softener examined at least once per year by an authorised
Winterhalter service technician.
7.1 Cleaning the inside of the container
Turn off the water supply.
Drain the container completely (scoop out salt and water).
Remove filters.
Remove any sludge or dirt particles using a cloth or brush.
Insert filters.
Open the water supply.
Refill new regeneration salt (approx. 20 kg).
7.2 Cleaning the dirt trap
Turn off the water supply.
Remove the dirt filter, clean it and reinsert
it.
Open the water supply.
7.3 Check backflow preventer type HD
Is the backflow preventer installed according to the connection
diagram (page 10)?
Is the backflow preventer clean?
No visible leakage, corrosion or other damage?
