4.4. CONTROL AND SECURITY DEVICES (ALARMS AND CONTROLS)
The control devices available in this unit, if activated, will be displayed will following symbols:
id
open door: the cycle stops and will be restarted from the point of interruption once the door is closed again.
HP
alarm high pressure.
AL
alarm minimum temperature.
AH
alarm maximum temperature (alarm H.A.C.C.P.).
Pr1
error chamber probe.
The activation of one of these alarms prevents the cycle start. If a cycle is in progress it will be blocked.
Pr2
error core probe: in this case it’s not possible to start a temperature cycle. However, all time cycles can be executed.
Each warning is joined to an acoustic alarm. Press any button to stop it.
5. ORDINARY MAINTENANCE
5.1. WARNINGS
Carefully read all security and warning instructions in the introduction page.
The manufacturer is not liable for any damages caused by improper operations or by any improper use of the appliance, as from the
specifications of this instruction manual.
It is necessary to remind users about some basic operations to be carried out before starting cleaning:

Disconnect the machine from the electrical feeding network unplugging the main switch and the feeding plug.

Use protective gloves to protect the hands.

Do not introduce any tools, screwdrivers or other instruments between the moving parts or the protection elements.

Do not pierce pipes, or open the gas valves.

Do not pull the feeding cable.

Do not remove protective and security devices while carrying out ordinary maintenance operations.
5.2. INTERIOR CLEANING
The machine must be cleaned either inside and outside before starting any working cycle and at the end of any cycle , thus
preventing the arising of germs, bacteria, virus and unpleasant smells – together with anything else that may harm food.
The machine must be cleaned using degreasing and disinfectant products commonly used in the kitchen. Avoid steel wool, abrasive sponges,
solvents and any products, which might corrode or scratch the surfaces.
In short, the blast chiller must be clean when used and must be left clean at the end of every working session.
The racks are easily removable for cleaning. Reposition them once they have been washed.
It is important to carefully wash the inside of the unit and the door.
Do not scrape with sharp tools, especially the cool generator.
Remove the drain cap on the bottom of the chamber to let the water flow out and put it back before starting a new working cycle. The waste
water will be drained into the drip tray (optional in mod. AS.003 (3.10)), which will be emptied and cleaned every day by pulling it out from the
front bottom of the unit.
Keep the door ajar, so as to allow air circulation inside the chamber and prevent bad smells and mould from developing.
Prevent any salt pouring on the surfaces of the blast chiller: if this should occur, clean the surface properly and immediately.
5.3. CLEANING OF THE CONDENSER
The condenser needs to be cleaned at least all 2 months. In the air cooled models, the condenser is placed on the front side of the unit, whereas
the models equipped with remote unit have the condenser in the group itself. This important operation ensures the proper functioning of the
unit and avoids the intervention of the security switch (HP).
Put protective gloves on to carry out these operations: the condenser tongues are very sharp. Also use protective glasses and a protection mask
for the respiratory tract.
Carefully follow the instructions listed here below:

Disconnect the plug from the power point before starting;

In case of models AS.003 (3.10), AS.005C (5.12) and AS.005ST (5.12) blow an air jet into the condenser placed in the front of the unit;

On all other models strongly pull the front panel;

Turn the board carefully over in order to prevent damages to the control board;

Clean the condenser by removing all dust and down deposits, using a brush or aspirator along the wings, making sure not to bend them; in
case of greasy deposits, remove them by using a little brush dipped in alcohol;

Once finished, close the front panel;

Roll-in units have the condenser is at sight.
