It is strictly forbidden to remove guards or safety devices when performing routine maintenance
work. The manufacturer disclaims all liability that may arise if this regulation is not observed.
Emergency measures in case of fire
- Disconnect the unit from the electrical power socket.
- Do not use water to extinguish the fire.
- Use powder or foam extinguishers.
5.1 CLEANING OF REFRIGERATOR
The unit is designed to preserve blood and blood products so it is important to keep it clean for
reasons of hygiene and health. The appliance is thoroughly cleaned in our factory before delivery.
We recommend, however, that you clean the interior of the appliance before use. Before cleaning
the appliance make sure the power cord is disconnected.

To this end, we indicate cleaning products to be used for exterior and interior of the appliance:

surfaces

IN CASE OF BREAK OR LOSS OF BLOOD FROM THE BAGS STOWED IN DRAWERS OF
BLOOD BANK REFRIGERATOR, PLEASE REFER TO INTERNAL HOSPITAL OR
LABORATORY PROCEDURE FOR CLEANING AND DISINFECTION.
5.3 CLEANING OF CONDENSER
The condenser is a heat exchanger hence if it is dirty or clogged the air cannot pass freely into the
same, it cannot do its job properly and the efficiency of the refrigeration system falls down
proportionally.
FOR THOSE REASONS IT IS IMPORTANT TO KEEP CLEAN THE
CONDENSER WHERE TYPICALLY IT MEANS TO CLEAN IT MONTHLY
.
WARNING!!
always switch off the unit and disconnect power cord before cleaning, it is
dangerous to do it with power: fan may start suddenly at any time!
