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.
