Safety
Refrigerant must not be used in low-lying spaces such as assembly pits
or soakaways. Refrigerant is heavier than oxygen and therefore dis-
places the air you need to breathe. This can cause a lack of oxygen when
working in unventilated assembly pits.
Take suitable precautions to ensure that leaking refrigerant is not able to
get into the drainage system.
Special information on refrigerant R-1234yf and safety measures as well
as protecting personnel and objects, including fire protection can be
found in the safety sheets of the refrigerant manufacturer.
