5.3 Securing the unit
5.3.1 Tabletop units
For safety reasons, tabletop units should only be
placed atop a manufacturer-original oven stand
or base unit. Maximum working height for the
topmost rack is 63” [1600 mm].
Unit size 60 These units do not have height-adjustable feet;
instead, they are set up directly on the installation surface.
The installation surface must be level, clean and
free of grease. Unevenness across the width of
the unit must be no greater than 0.04” [1 mm].
A sealant band is affixed to the underside of the
unit to seal the installation site. This prevents dirt
from getting underneath the unit. When moving
the unit, take care not to damage this seal.
Mounting onto an oven stand:
Insert the two included neoprene blind rivet nuts
into the holes in the rear part of the underbody.
Place the unit onto the oven stand.
Secure in place using the screws provided.

Connect the unit to drinking water-quality water.
Install the unit with adequate backflow protec-
tion to comply with applicable federal, state, and
local plumbing codes.
Connect a flexible drinking-water connection
hose in accordance with EN 61770 / IEC 61770
or of similar quality. Take any necessary safety
precautions with the water tap, such as backflow
preventers as required by local code. (Not supplied by manufacturer)
The water connection hose must comply with
country-specific hygiene standards for drinking
water hoses.
Use only new hoses as water connections. Do
not re-use old hoses.

NOTICE
The manufacturer recommends preventative
inspection be conducted around six months
after unit commissioning to ascertain the
degree of limescale buildup in the steam generator, especially for CMP/CM units.
This inspection should be performed by a
trained technician.
7.3 Water treatment
> The water connection must not use treated
water with hardness below 5.2 gr/gal, as
such water is aggressive and corrosive, and
can shorten the lifespan of the unit.
> Connecting the SCC to water with hardness
below 7.3 gr/gal:
When the self-test begins, the system will
prompt the user to indicate the hardness of
the water the unit is connected to. Select
“Water hardness below 7.3 gr/gal “treated
water”.
> Observe all country-specific regulations
46
7 Water connection
regarding water and sewer connections, especially those regarding installation of water
intake points.
Only USA (not valid for CAN) In most cases, water connections do not require
additional filters or water treatment.
Filtration and/or water treatment (A, B, C, D)
may be necessary if water conditions are critical.
Contact the local water supply company to
inquire about water chloride levels (Cl–), chlorine
levels (Cl2) and hardness.
7.4 Selectingwaterlters
A) Fine filters We recommend fine filters with fineness of 5 -
15µm for filtering water contaminated with sand,
iron particles or suspended matter.
B) Active carbon filters If water contains high levels of chlorine Cl2 (over
0.2mg/l, corresponds to 0.2ppm; information
provided by water supply company), (typically
municiple supplied water).
C) Reverse osmosis system Due to corrosion risks, a reverse osmosis system
must be used if and only if chloride (Cl–) concentrations are above 80mg/l (corresponds to
80ppm, information provided by water supply
company).
Note: Ensure that the minimum conductivity
value of 50µS/cm (Micro Siemens) is being
maintained.
D) Water softening:
SCC: When used properly, these units remove lime
from water completely independently, so upscale
water softening is not necessary.
CMP: Recommended for treating water if severe calci-
fication occurs (without chloride contamination).
Systems: Weak acid decarbonization (H+ ion
exchange).
Sodium ion exchangers (as are commonly found
in dishwashers) are not recommended.
Phosphate metering is also not recommended
due to its negative effects on the water system.

7 Water connection
Important for treated water connections:
To increase filter capacity, split the water con-
nection like shown in chapter 7.2 into cold and
treated water inputs (not possible with size 60
units) - remove the common water supply line.
i
NOTICE
Unit size 60 is single water connection only.

an UltraVent is in use, the test will take around
20 minutes longer.
> To perform the self-test, check the hook
latches and the air baffle to ensure they are
seated correctly and no cardboard/plastic is
inside unit.
> The unit must be connected to water, waste-
water, and electricity as per installation
instructions; gas units must also be connected to gas supply and operational ventilation
hood.
> The left side panel must be closed.
> With tabletop units, insert a flat container into
the middle of the rack, with the opening facing down.
> With floor units, insert two containers into
the mobile oven rack: one centered in front of
