ELECTRICAL CONFIGURATION
A number of different electrical connection options are available for each 60cm and 90cm model
referred to in the table.
The names of the models have different suffixes to identify the power supply rating. Example:
- “GW4060-1”, ”GW1160-1” and “GW4190-1” refer to 230V single-phase models: “ 1N~ ”
- “GW4060-3”, “GW1160-3” and “GW4190-3” refer to three-phase models, 230V between phases, without
neutral: “ 3~ ”
- “GW4060”, “GW1160” and “GW4190”. If the model does not have a suffix it will be three-phase, with
neutral, 400V between phases: “ 3N~ ”.
- “GW4060U”, “GW1160U” and “GW4190U”. The “U” suffix refers to “North American models”, convertible

3GENERAL WARNINGS
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.
The maximum weight which can be loaded on the door, including the weight of the instrument
trolley, must never exceed
GW1160, GW4060, GW4190: 37kg
GW2145: 18kg
- if the weight of the instrument trolley and baskets is excluded, the maximum load must never
exceed:
GW1160, GW4060, GW4190: 23kg.
GW2145: 15Kg
For optimal DRYING, the load for processing must never exceed 15 kg. (only for GW4060,
GW4190 Series).
With use of the glassware washer, localised or general discolouring of the heating element may
occur. This is normal since it is due to the operating mode and does not reduce the appliance’s
effectiveness.
In the event of malfunction, disconnect the appliance from the electricity supply and turn off the
water tap. Then contact your nearest authorised Service Centre.
Open the door carefully, first waiting for the wash cycle to end.
The appliance has an automatic door opening system; do not force the door open while a program
is in progress.
The appliance must only be used by staff suitably trained in its operation.
The chamber of the appliance is not designed for users to climb into it. The user must never climb
into the chamber; this might put his safety at risk (ref. 7.102 IEC61010-2-040:2005).
Do not place flammable substances inside the device. Do not use flammable detergents.
Never place alcohol or solvents such as turpentine, which might cause an explosion, inside the
appliance. Do not place materials dirty with ash, wax or paint inside the appliance.
DEMI WATER ABSENCE
If demineralised water is not available, the user is responsible for ensuring that the quality of the
water supplied to the medical device does not cause mineral salts or other substances to be
deposited on the treated instruments, rendering their subsequent use unsafe.
Never touch the heating element immediately after the end of a wash programme.
Do not touch any residual liquids left inside the washing chamber; scalding hazard (ref. 7.102.c
IEC61010-2-040:2005).
When moving the appliance around, a forklift truck or pallet truck must be used.
Before leaving the factory, the base of the appliance is secured to a pallet, which is used for lifting
and transporting it.
Do not use appliances which have been damaged in transit!
If in doubt, contact your dealer.
Once decommissioned, the appliance must be rendered unusable. Cut the power supply cable
after removing the plug / disconnecting the cable from the power socket.

4.2 CONTROLS - DETAILED DESCRIPTION
BUTTONS
DESCRIPTION
On/Off
The button is operational with the door opened or closed.
The button turns the device’s interface on and off, allowing its use. Hold it down for 2
seconds for both switch-on and switch-off.
Once the appliance has been switched on, the code of the selected program appears on
the display (e.g. “Pr 03”).
When the interface is switched off, the display shows a flashing “OFF” message.
When the door is open, the display shows 4 horizontal dashes and none of the other
interface buttons are active.
The device is still powered up even when the interface is off.
-
Drying +/- (only on GW4060, GW4190 series)
The buttons increase/decrease the intensity (and duration) of the drying phase.
Holding down the “Drying–” button selects a separate drying program; the display shows
the message “Pdry”.
If the cycle set has a drying phase, these buttons are enabled and the drying LED
illuminates.
If the cycle set does not include a drying phase, the buttons are not enabled and the
drying LED remains off.
These are “first touch” buttons; there is no need to hold them down.
The drying duration set is displayed as follows:
- 3 horizontal bars on the display; maximum time setting, default time
- 2 horizontal bars, medium duration
- 1 horizontal bar, short duration
Start/Stop
This button starts the selected cycle or interrupts a cycle in progress. It must be held
down for 2 seconds.
Two beeps sound when a cycle is started or stopped.
The button is also used (again holding it down) to confirm the value of an appliance
parameter during modification.
Functions
Hold down: access to the appliance setup parameters, password required. Refer to the
SETUP MODE - “FUNCTIONS” section for a detailed explanation.
Short press: whenever the Functions button is pressed,
the display screen changes; the various screens show the parameters of the cycle
selected in combination with the LED which explains their meaning.
For a full understanding of the values shown on the display, note that they depend on the
appliance’s status:
1. Appliance in standby
2. Washing cycle running
