Operative Instructions
Before proceeding with the various operations, the
above listed operators, must have carefully read and
become familiar with this manual.
The glasswasher packaging, in addition to the machine's
documentations, contains the two spray arms that will
be applied on the chamber, the flexible hoses for the
hydraulic connections the drain pipe, the supply wire,
the emergency release key and the USB key.
Upon delivery, check that the glasswasher is intact and
that the above-described material is actually present.
For the installation, wiring and hydraulic diagrams
(water filling and draining) contact the manufacturer.
2.5 Product analysis
The glasswasher was tested by applying «UL 61010-1
CAN/CSA-C22.2 61010-1-12 IEC 61010-2-010 61010-
2-040 Safety requirements for electrical equipment for
measurement, control and laboratory use. Part 2-040»,
where the glasswasher is expected to:
• be used only for internal uses;
• be operational up to a maximum altitude of 6562 ft
(2000 meters);
• be operational at a temperature between 41 and
104°F (5 and 40°C);
• operate in an environment with a maximum humidity
of 80% for temperatures up to 88°F (31°C), decreasing
linearly to 50% at 104°F (40°C);
• with a primary voltage fluctuation up to ±10%
compared to the nominal voltage;
• temporary type overvoltages:
- of short duration, which may occur between the line
conductor and the system earthing, which may have
a voltage equal to the power supply voltage on the
line-n1200V, and a duration up to 5s;
- of long duration which may occur between the line
conductor and the system earthing, which may have a
voltage equal to the power supply voltage on the line-
n250V, and a duration greater than 5s;
- overvoltage category II;
- pollution degree 2.
• The validation of the product was made by the
manufacturer in compliance with standards
UNI-EN-ISO 12100; IEC 61010-1; IEC 61326-1;
2006/42/EC; 2014/30/EC; 2011/65/EC.
• The machine does not cause harmful vibrations.
• The residual radiation emitted within the limits is
non-ionizing.
• The shelf life cycle of the device is 10 years.
• The machine must not be dumped when scrapped,
as it contains materials subject to legislation requiring
disposal at special centres.
2.5.1 Inlet water quality
The quality of the water used in all stages of cleaning is
important for good results.
The water used in each stage must be compatible with:
• The material which the machine is made of.
• The chemicals used in the process.
• Process requirements for the various stages of the
process.
The main factors for good inlet water quality in relation
to the effectiveness of washing are:
HARDNESS
The high hardness of the water generates a detergent
inactivation, reducing its efficacy. It also causes limescale
deposits in the machine, jeopardizing the cleanliness of
the glassware and the machine, especially on hot parts
(ex. heating elements).
IONIC CONTAMINANTS
A high concentration of ionic contaminants may cause
corrosion of steel, manganese or copper instruments.
MICROBIAL CONTAMINANTS
Microbial contaminants can increase the microbial
contamination of the instruments at the end of the
wash.
The manufacturer therefore recommends that:
- the water used in the pre-rinse and washing stage
should be of drinking quality according to the
“Guidelines for drinking-water quality, 4th edition”
published by the WHO.
- deionized water is used for the rinsing. A typical
specification for deionized water is:
Ion concentration H+
4.5…7 pH
Conductivity
< 30 μs/cm
TDS
< 40 mg/l
Maximum hardness (CaCO
3
)
< 10 mg/l
Chlorine
< 10 mg/l
Heavy metals
< 10 mg/l
Phosphates
< 0.2 mg/l as P
2
O
5
Silicates
< 0.2 mg/l as SiO
2
Endotoxins
< 0.25 EU/ml
Colony-forming units (CFU)
< 100 for 100 ml (*)
(*) for rinsing the maximum limit changes to 0.
Further advice should also be obtained from
manufacturers of laborarory equipment. Where
local standards are stricter than the provided
recommendations, they should be followed.
