fixtures. However, it may be necessary to clean out your faucet
aerators and showerhead periodically during this time to remove
pieces of scale that have dislodged from your pipes. This effect
will stop once the pipes have been de-scaled.
After installation of Scale TAC-ler Plus, low or phosphate-free
cleaning products (for clothes and dishwashing) are recommend-
ed to achieve optimum results. Modern surfactant or detergent
based, liquid soaps are preferred over old-fashioned caustic solid
soaps.
7.1 Water heaters
Existing mineral accumulations in your water heater may also de-
scale after the installation of your Scale TAC-ler Plus System. If you
have a traditional water heater, we recommend that you clean out
this material by opening the bottom drain valve on the hot water
heater 30 to 60 days after installation of Scale TAC-ler Plus. Be sure
to turn off the electricity or gas to your water heater before drain-
ing your tank. Follow the manufacturer’s instructions for draining
and flushing the tank. The good news is that a clean water heater
uses much less electricity or gas to keep the water hot!
7.2 Dishwashers
To accelerate de-scaling in your dishwasher, you may wish to put
a cup of white vinegar in the upper basket during the washing
cycle for the first few weeks. You can also use citric acid or a
commercial product like CLR or Lime Away instead of the white
vinegar. This will help dissolve the existing scale in the washer
arms and inside surface of the dishwasher. You may need to do this
until all of the scale in the plumbing is dissolved. If you are using
harsh dishwashing detergents that have low pH, high chlorine,
and phosphates, some of the nano-crystals formed by the Scale
TAC-ler Plus system may break down and cause spotting on the
dishes. We recommend that you reduce your soap usage as much
as 50%, and that you use eco-friendly phosphate-free dishwash-
ing detergents. Using an anti-spotting agent such as Jet-Dry
®
or
Finish
®
may also be useful.
7.3 Glass shower doors
Over a few weeks you may see the existing scale slowly dissolve in
your shower heads thereby increasing water flow. You may need
to clean the inlet screen of your shower head during the first few
weeks as mentioned previously to remove some of the scale that
is being removed from your pipes. We recommend that you first
clean the shower with a cleaning product that dissolves old scale
that has built up before installation of the Scale TAC-ler Plus con-
ditioner system. CLR or Lime Away are good cleaner choices for
this purpose. We then recommend that you coat the walls in the
shower, and your glass shower doors with Rainx, a commercial
product used for automobile windshields. The Rainx allows the
majority of the nano particles to be easily washed to drain. The
few nano particles that are left can be easily wiped down because
they can no longer adhere to the sides of the shower.
8. Maintenance
The filter cartridge in your system will need to be replaced every
2 years or sooner if hard water scale is noticed. Use only genuine
Stiebel Eltron Scale TAC-ler Plus Cartridges for replacement. Use
of an alternative media may adversely affect the performance of
the system.
8.1 Obtaining replacement filter cartridges
Replacement filters can be obtained from your dealer. Replace
the Scale TAC-ler Plus cartridge every 24 months or if hard water
scale returns
- Replacement cartridge part number: 692443
8.2 Filter cartridge replacement procedure
f
Turn off the water supply to the system using the ball valve
on the inlet side of the system or your main incoming water
line shut-off valve. Open a hot water faucet downstream of
the housing to release pressure. Close the shut-off valve on
the outlet of the system if so equipped. Depress the pressure
release button on the top of the filter housing cap to allow
any remaining pressure inside the housing to escape.
f
Unscrew the housing sump from the cap using the spanner
wrench (included with original purchase of your system).
f
Take out the old filter cartridge and discard it.
f
Scrub the bottom of the housing and cap with dish soap and
warm water using a sponge or soft cloth. Fill 1/3 with water
and add about 2 tablespoons of household bleach (unscent-
ed). Scrub to disinfect (we recommend that you use rubber
gloves). Rinse all parts thoroughly!
f
Inspect the O-ring. The housing O-ring should be replaced
if it is kinked, cracked, stretched, etc., or if any leakage be-
tween the housing cap and the housing sump is detected and
does not seal after proper tightening. Lubricate the O-ring
only with food-grade silicon lubricant if needed. DO NOT use
petroleum jelly.
f
Remove the protective plastic wrapping from the new filter
cartridge and insert the cartridge into the housing sump,
making sure that it slips over the standpipe in the bottom of
the housing. The wider part of the cartridge is the top.
f
Check to make sure that the O-ring is seated properly at
the top of the housing sump. Screw the housing sump onto
the housing cap. Hand tighten only. It is not necessary to
over-tighten to create a good seal. You can use the spanner
wrench for convenient grip, but do not use excessive force.
f
Turn on the water supply slowly to allow the system to fill
with water. Depress the pressure release button on top of
the unit again to release any trapped air. Inspect carefully for
leaks. If a leak is found, first inspect the O-ring to ensure that
it is seated properly before tightening the sump more. Tight-
en using the spanner wrench as necessary to achieve a good
seal and stop leaks (do not use excessive force).
f
Flush the system by running water from a nearby faucet for 5
minutes prior to using the water.
