3.1.1 Rust on industrial dishwashers
• Large-scale industrial dishwashers in general as well as our dishwashers
are made of stainless materials, but despite this, there are still situations
where rust can occur on “stainless” materials.
• We are going to describe a few reasons for this here, so that you, as a user,
service engineer or other type of personnel, can avoid this.
• Rust usually occurs due to the fact that something that is not stainless finds
its way onto the stainless surface. The non-stainless particles will soon
start to rust, and then contaminate the stainless material, which also starts
to rust. If no action is taken at this point, serious damage such as a hole in
the material can occur.
N.B.! If rust spots have developed, they must be dealt with immediately by a per-
son authorised to do so!
RISK SITUATION CAUSE DECLARATION / ACTION
Drilling holes when installing a
detergent device.
Using a drill or hole saw that has pre-
viously been used for ordinary non-
stainless materials.
“Contaminated” hole-drilling tools
can cause enormous damage in the
form of pores in stainless plates.
Never use a cutting tool that has pre-
viously been used on other materials
or blackplate.
Using blunt tools when drilling holes. Stainless plate, which has overheat-
ed during hole drilling, may lose its
“stainless” properties.
This can show up as rust around the
hole for the detergent cell.
Shavings from hole drilling. The shavings from drilling or hole
sawing are usually heated so much
that they lose their stainless proper-
ties.
They must always be removed by
hand! Washing after hole drilling is
not enough!
Rust spots that occur during nor-
mal operation and use.
Minerals, e.g. ferrous gravel or
earth, from dishware or food (vege-
tables and root vegetables) that has
been lying in crates, find their way
onto the stainless surface. Minerals
(gravel) can also be found on the
wheels of catering trolleys.
Daily cleaning is always important.
Use a suitable brush for “mechani-
cal” cleaning, e.g. in the wash tanks,
on the wash trays and filters.
Steel wool. Ordinary steel wool is not
stainless, and can cause serious
damage to stainless surfaces and
plates.
Use stainless cleaning pads. Re-
move all ordinary steel wool from the
catering facility / restaurant.

3.5.1 Electrical connection
Information about electrical connections is available on the machine’s wiring dia-
gram which is provided on delivery. Store these in the special plastic document
wallet.
• The machine is designed for quick electrical installation.
• The machine must be connected to a lockable power switch. This should
be placed on a wall, well-protected from water and from the steam which
escapes when the machine is opened.
• Connect the cable at (1), or alternatively the machine may have an electri-
cal connection from the floor (6). Protect the incoming cable with, e.g. Pipe
for connection cable, WD212.4102 (option).
• Check the direction of rotation of the pump motors during operation when
the tanks are full of water. The direction of rotation must conform without
exception to the direction of the arrow on the pump. Stop the dishwasher
immediately if the direction of rotation is incorrect and change two of the
incoming phases.
After completing the installation, switch on the power switch and all circuit break-
ers.
3.5.2 Water connection, regardless of any options
• A shut-off cock must be installed on the incoming pipe.
• It is important that the water supply has sufficient pressure to ensure the
correct flow of water to the machine. The required water flow and pressure
can be found in the TECHNICAL SPECIFICATIONS. If the water pressure
is too low, a booster pump must be fitted.
The water pipe is connected at (2), or alternatively at (7). If the machine is con-
nected with a hose, this should be steel braided and have an internal diameter of
at least 12 mm.
The water connection on the machine is fitted with a filter, non-return valve and
vacuum valve.
As the machine is fitted with a “break tank”, the connection is fitted with a filter and
non-return valve.
3.5.3 Ventilation
The machine’s heat load for the room is stipulated in TECHNICAL SPECIFICA-
TIONS.
Connection to the ventilation duct is done at the outfeed (5) and the infeed (12).
If a hood is fitted over the machine, it must cover the drying rack after the ma-
chine.

3.5.4 Drain/waste pipe
The waste water system connected to (3 or 8) should consist of a 50mm metal
pipe that will withstand mechanical impacts. The waste pipe must run to a floor
drain, where its opening must be above the water level.
The drain can be fitted to the right or left. Remove the perforated section of the
end plate and pull the pipe through the hole. Connect the drain and run to the floor
drain where it should flow freely above the water level.
Ensure that the drain connection is kept in place by using e.g. cable ties in the
designated areas.
3.5.5 Detergent and drying agent
• Check what your machine is equipped with, which depends on the model,
machine type and country.
• Use the same make and type of detergent and drying agent.
• With machines connected to cold water, the water pipe temperature may
be too low for use of powder or paste type detergents.
• If liquid detergent is used together with Wexiödisk’s detergent pump, the
detergent must be placed under the machine’s tank level.
If equipment for a different type of detergent is used, it should preferably be put
on the wall behind the machine to avoid holes being drilled unnecessarily in the
machine.
The process of setting the detergent and drying agent dispenser is described in
the ADJUSTMENT INSTRUCTIONS.
