8. MAINTENANCE/SANITIZING
The Denver softeners, being automatic, do not require a com-
plex maintenance.
In order to ensure a correct working of the system it is enough
to make the following checking from time to time as showed
in the table below:
It is important not to make the sanitizing and the descaling
treatment at the same time, because the chemical products can
react in a dangerous way. You should alternate both processes as per
indicated frequency.
SALT FILLING
Please revise the level of the salt inside the tank.. It should be
mínimum: 1/3 of the tank. If the system runs out of salt before
the refilling the softener will produce hard water. When finis-
hing the checking please make sure that the cover is correctly
closed.
NOTE:
In humid areas it is best to keep the salt storage
level lower and refill the tank more often.
RECOMMENDED SALT:
Coarse salt tablets or balls with less
than 1% of impurities.
NOT RECOMMENDED SALT:
Rock salt, with impurities, block,
granulated, table, ice melting, or for kitchen use.
BREAKING A SALT BRIDGE
Sometimes, a hard crust or salt bridge is formed in the brine
tank. It is usually caused by high humidity or the wrong kind
of salt. When there is a salt bridge, and empty space forms
between the water and the salt. Then the salt will not be dis-
solved in the water to make brine and without brine the resin
bed does not regenerate and you will get hard water.
If the storage tank is full of salt, it is hard to tell if you have
a salt bridge because salt is loose on top but the bridge is
under it.
Take a tool or a broom handle, for instance, and hold it next
to the water softener, measure the distance from the floor to
the rim of the water softener. Then push the broom handle
straight down into the salt. If you find a hard object, it is most
likely a salt bridge. Carefully push into the bridge in several
places to break it.
“WARNING”
Do not use any sharp or pointed objects as you
may puncture the brine tank
SANITIZING:
Every year it is recommended to make an sanitizing process
as follows:
1.
Open the covers of the salt tanks and put inside about 20 a
30 ml (2 or 3 caps) of Bacwater (652100.) inside the funnel.
Close again.
