C.5 HACCP CONNECTIONS
(ACCESSORIES)
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 ROUTINE MAINTENANCE
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
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.
