SAFETY INFORMATIONS
The LAB freezers contains environmentally friendly but flammable refrigerants. It means
danger of explosion if for any reason the refrigerants are allowed to escape from the
system.
The refrigeration system must never be accessed by unauthorized personal.
When transporting and installing the unit, ensure that no part of the tubing system is
damaged.
If the tubing is damaged and leak occurs, avoid any ignition sources and naked flames near
the unit, and ventilate the room immediately.
In order to avoid formation of flammable gas/air mixtures in case of a leak from the
refrigeration system, the room where the unit is placed must have a volume equivalent to
1m³ per 8 gr. of refrigerant in the cabinet.
WARNING!!!
The ventilation openings must never be covered or blocked.
Never use a stream or water cleaning device during cleaning or defrosting in order to avoid
short circuits in the electrical system.
Do not place any electrical devices in the freezer.
Products containing flammable gasses and explosives must not be stored in the freezer.
All units should be provided with installation and operating instructions. In addition to the
Clearances Installation, the instructions should contain such directions and information that
the manufacturer considers necessary for installation, maintenance, and use of the
refrigerator.
Installation and operating instructions should be provided with cautionary statements
concerning the handling, moving, and use of the refrigerator or freezer to avoid either
damaging the refrigerant tubing, or increasing the risk of a leak.
The shipping carton of a refrigerator or freezer that employs a flammable refrigerant
should be marked
"Caution - Risk of Fire or Explosion due to Flammable Refrigerant Used. Follow Handling
Instructions Carefully in Compliance with U.S. Government Regulations".
The warning marking should also appear on the shipping carton, see below.

improper service.
