C.4.1.2.2 Service alarms requiring service center assistance

When the alarms listed below occur, call the service center for
assistance.

All alarms will be stored as follows: the “TEMPERATURE”
display shows the alarm number, e.g. “AL 1”, “AL 2”, etc.,
whereas the “TIME” display shows the ALARM CODE, e.g. “E1”,
“b1”, etc...

If no alarm is active

: the first alarm, i.e. the last to occur, is

displayed.

Use the

buttons to scroll the stored alarms.

After displaying the last alarm, the

“——”

message will appear

on the display and after 12 seconds the unit will automatically
go back to the main menu.
When the next alarm occurs, the current ones will be cancelled
(automatic reset).

If an alarm is active,

going into the utility will silence the buzzer

and simultaneously access the alarm message display.

Use the

buttons to scroll the stored alarms.

After displaying the last alarm, the l

“——”

message will

appear on the display and after 5 seconds the unit will
automatically go back to the main menu.
The function for cancelling from the memory is disabled when
there are alarms active (i.e. the reset is disabled).

To cancel the alarms, press

together for 5

seconds.

ATTENTION:

The reset function is disabled if the operator did not

see the stored alarms. When the reset function is enabled the
message “RES” appears on the TEMPERATURE display.

Refer to the handbook enclosed with the kit for instructions
on installing the accessories.

The board has a serial communication line for interacting with
other units, printers or a HACCP control station in a network.

This can be connected in the following ways:
• directly to a device that communicates in TTL (e.g. the FT190ELX
printer), by setting the parameter E485=”Prn”
• to an RS485 communications network, by setting the parameters
E485=”PC” and PRTY=”1" (refer to the handbook supplied with
the kit) inserting the conversion card RS485-LK-P and
Adr=”Network address”.

D.1.1 PRECAUTIONS FOR MAINTENANCE

Routine maintenance tasks can be performed by non-
specialised personnel. When performing maintenance please
follow the instructions closely, keeping safe at all time.

The

manufacturer declines any responsibility for injury sustained
from unsafe acts.

ATTENTION:

do not touch the appliance if hands and/or feet are wet. Before

performing any cleaning or
maintenance disconnect the
appliance from the electrical
source and carefully unplug the
appliance. It is DANGEROUS AND
UNADVISEABLE to remove the
safety guards, AND IS NOT
REQUIRED for routine
maintenance. Wear protective
gloves when cleaning the
condenser. Do not use scissors,

screwdrivers and sharp objects on the cooling circuit.

D.1.2 CLEANING THE CABINET AND ACCESSORIES

It is advisable to clean the chamber every week; increasing this
frequency according to appliance use.
Before using the unit, clean all the internal parts and accessories

with warm water and either neutral soap or products
that are over 90% biodegradable (in order to redu-
ce the emission of pollutants into
the environment), then rinse and dry
thoroughly. Do not use solvent-
based detergents (e.g. trichloro-
ethylene) or abrasive powders for
cleaning. Coat the metal panels with
vaseline oil.
The trolleys must be cleaned with high pressure

water jets.
Drain off the water used in the process of cleaning by removing
the drain plug at the bottom center of the chamber, so that the
liquid flows out into the drain tray under the cabinet. This tray
must be emptied periodically (AOFP061U4-061U, AOFP101U4-
101U, AOFP102U4-102U models).
Refit the drain plug immediately after the cleaning.

Note: make sure the drain tray has been emptied before
removing the drain plug.
