2. Warning in relation to R290 refrigerant
This equipment is designed to use only R290 (propane) refrigerant, which is hermetically
sealed under pressure in the refrigeration circuit. Repairs to this equipment may only be
carried out by a specially trained service technician in accordance with national
legislation relating to flammable substances! The service manual is available on request.
Do not interfere with, pierce or expose the cooling circuit to higher temperatures.
Do not release refrigerant into the atmosphere.
Do not try to speed up the defrosting process in any way (e.g. by heating).
The device must be placed in a room with a minimum surface area of 4 m2.
R290 is a flammable gas (propane) and is heavier than air. For this reason, its concentration
rises most near the ground during a leak, but it can be agitated (e.g. by drafts, fans, etc.) to
higher layers. The propane used in this equipment is an odourless gas.
Do not use the unit in a room with an open flame or other strong heat source (e.g.
cigarettes, candles, etc.) or electrical discharges. Place the appliance in a room that can be
ventilated if necessary and where gas accumulation is not possible.
If propane is detected or even suspected in the room, do not allow unauthorized persons
to search for the location of the leak. In this case, evacuate all persons from the room,
open the windows, exit the room, and notify the local fire station of the propane leak. Do
not allow any person to return to the room until the fire department commanding officer
or certified service technician has determined that the hazard has passed.
FAILURE TO FOLLOW THE ABOVE INSTRUCTIONS MAY RESULT IN FIRE, EXPLOSION,
PROPERTY DAMAGE, INJURY OR DEATH.
