Caution
Avoid any physical contact with the refrigerant as this may cause frostbite to the skin and
limbs or retinal damage. Use personal protection equipment against effects of refrigerants
VBG 20 (goggles, gloves, etc.)!
Refrigerant (odourless and tasteless) ejects atmospheric oxygen and can cause
suffocation. TLV values (for R407C: 1,000 ppm in 8h) and practical value limit DIN 8960
(for R407C: 0.31 kg/m³ area) must be observed. If refrigerant does escape only enter the
machine room with heavy duty respiratory protective gear. Observe the safety data sheet.
Refrigerants and compressor oil develop toxic, noxious substances in tandem with naked
flame. Do not inhale! Do not smoke in the machine room!
There may be an allergic reaction if compressor oil is touched or swallowed. Avoid physical
contact! Observe safety data sheet.
