Extreme operating conditions

Low Temperatures
Use anti-fog coated visors (PCaf) or use anti-fog agent "klar-
pilot gel" to prevent visor inside from steaming up.
High Temperatures / Alternating Thermal Stress
WARNING

damage, e.g. bubbles in the visor.
The coating may dissolve in some places on visors marked with
PCas and PCaf. The facepiece is fully serviceable until the end
of the operation. Replace visor after use.
