2INTENDED PURPOSE AND CLASSIFICATION
2.1 INTENDED PURPOSE
PRODUCT DESCRIPTION: professional glassware washers, laboratory glassware washers (GW –glassware
washer).
Model
Key characteristics
GW0260
Laboratory glassware washers, 60 cm wide, without drying system, washing chamber in
stainless steel AISI304.
GW1260
Laboratory glassware washers, 60 cm, without drying system, washing chamber in stainless
steel AISI316.
GW4260
Laboratory glassware washers, 60 cm, with forced-air drying system, washing chamber in
stainless steel AISI316.
GW4290
Laboratory glassware washers, 90 cm, with forced-air drying system and side cabinet to take
detergent jerry cans, washing chamber in stainless steel AISI316.
INTENDED PURPOSE:
treatment, through washing and thermal disinfection, of glassware, laboratory components
and reusable components.
. The device was tested using the chemical products recommended in this manual. The use
of chemical products other than those recommended may impair the device’s fitness for its
intended purpose and its safety.
The device does not sterilise the load.
Sterilisation is performed by other devices (e.g. steam sterilisers) and is a treatment which
follows on from washing and thermal disinfection.
The washing trolley supports the load and determines type of load which can be processed
in a cycle. (The device is supplied as standard without washing trolleys; contact the
manufacturer for advice about the trolleys best suited to your needs.)
The instructions provided by the manufactures of the items in the load and the glassware
should always be followed when choosing the most appropriate treatment.
The operator’s own knowledge, especially of the Programs Table installed in the device
and the type of items for processing, is essential for selection of the correct treatment cycle:
the device offers various cycles with different time-temperature exposure (i.e. parameter A0)
values, which must be selected depending on the criticality of the load for processing.
It is essential to check the compatibility of the load for treatment with the specific washing
cycle chosen, in terms of the maximum temperatures reached and the chemicals used.
Information supplied in compliance with IEC 61010-2-040.
Any use other than that described in this manual constitutes misuse.
The manufacturer declines all liability for uses other than those stated above.
The manufacturer declines all liability for any damage caused by the use of the device to wash
instruments not approved by their manufacturers for automatic decontamination by means
of thermal disinfection.

SYMBOL
MEANING
Flammability hazard.
“Crossed dustbin” symbol. This device is tagged under European Directive 2012/19/EU ON WASTE
ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE) (ref. annex IX of directive). The symbol appears on
the product’s technical dataplate and the pack label: at the end of its working life, the product must
be consigned to a disposal plant for recovery and recycling in accordance with the relevant legislation
in the country of installation. Contact the specialist disposal consortia.
The management of WEEE (waste electrical and electronic equipment) is the responsibility of
manufacturers, who must plan and operate collection systems; used equipment can now be
consigned directly to the dealer free of charge when purchasing new equipment of the same type.
All disposal expenses will be borne by the manufacturer only when purchasing an equivalent new
device to replace the previous one.
At end-of-life the device may be contaminated, especially the chamber and water circuit (e.g. if the
device has ended its working life due to a fault that has caused the failure of the last thermal
disinfection cycle): take appropriate care when decommissioning.
Make sure that it is scrapped correctly to safeguard the environment and health.
Once decommissioned, the device must be rendered unusable. Cut the power supply cable after
removing the plug / disconnecting the cable from the power socket.
Before the old device can be disposed of, all accessible, old batteries and storage batteries must be
separated from the old device. The same applies to lamps, which can be removed from the old device
without damaging them. The end user is also responsible from obliterating any personal data on the
old device.
Notes on the recycling of materials
Help to recycle all materials marked with this symbol. Do not dispose of these materials, especially
packaging, with household waste; use the special recycling bins or the local collection systems
provided.
CE marking; the manufacturer guarantees compliance with the EU directives applicable to the
product.
Type of product “GW” – Laboratory glassware washers.
#
The # symbol identifies the Model (e.g. “GW4260”)
REF
The REF of a product, which appears on its technical dataplate, is its “catalogue number”, the code
which enables unique identification of its configuration (e.g. “GW4260-SC-000”).

5.2 GENERAL WARNINGS
MAXIMUM LOAD WEIGHT
Leaning or sitting on the open door of the device might cause it to tip over, putting people in
danger. The door is not designed primarily to support loads.
Safety information: the maximum weight which can be loaded on the door, including the
weight of the instrument rack, must never exceed: 37 kg. If the weight of the instrument trolley
and baskets is excluded, the maximum load must never exceed: 23 kg.
N.B.: the maximum load which can actually be processed depends on the correct arrangement
of the items, as instructed in the “Preparing the Load” section. In particular, items in the load
must never be overlapped.
MALFUNCTIONS and PERFORMANCE ANOMALIES
In case of operating anomalies or unforeseen events: read the “ALARMS” section of this
manual and, if appropriate, contact your nearest Authorised Service Centre.
In the event of water leaks: disconnect the device from the electricity supply and turn off the
water taps.
If the device’s interface display remains off or unresponsive even with the main switch
correctly set ON: do not touch the display as this may trigger unexpected operation of parts
of the device. Switch the device off using the main switch. Wait at least 10 seconds after
switching off before switching back on again.
Refer to the “TROUBLESHOOTING" section.
If changes in the device’s performance are noticed check:
1. That all operating conditions are as specified by the manufacturer in this manual and the
documentation supplied with the product.
2. That all maintenance procedures and recommended intervals have been complied with,
If the device’s performance is non-compliant, contact the authorised after-sales service to have
it checked and repaired.
The USB port on the product cannot be used for USB charging.
The port must only be used with the USB sticks supplied by the manufacturer and according to
the methods indicated in the user manual.
Maintenance: change drying filter (if installed)
The device provides an alert when the filter needs changing. Keeping the filter in operation after
the end of its useful life will lead to poor drying results. If the filter is fouled, the drying air flow
rate is reduced.
The filter’s useful life may be less than the preset nominal time, depending on the amount of dirt
in the environment. If drying performance deteriorates, users should have the filter changed
earlier. The device does not signal this type of wear, but only wear arising from the hours actually
worked.
