

If working in areas subject to risk of explosion spray the mask with an
antistatic spray which is compatible with the eyes and skin and which will not
damage rubber and plastics.

After use, remove the filter (or breathing tube) before cleaning and disinfecting.

6 CLEANING AND DISINFECTING

Disassemble the face mask only if it is particularly dirty or if it is difficult to clean by
washing only.
Clean  the  face  mask  with  warm  water  and  neutral  detergent.  Do  not  use  organic
solvents  for  cleaning  the  visor  and the rubber parts. Disinfect the face mask after
every cleaning cycle by soaking it in a disinfectant bath. Use only disinfectants that
will not damage the rubber and plastic components of the mask. Rinse thoroughly
under  running  water  and  allow  to  air  dry  away  from  direct  sun  light  and  at
temperatures lower than 50°C.

6.1 Procedure for sanitization from COVID19 (circular n ° 5443 of 20-02-2020
of the Ministry of Health).

• Carry out the 1st wash with soap water under running water. Do not immerse the
device.
• Immerse the mask in a solution of water and sodium hypochlorite (0.1% -0.5%),
or ethanol (62-71%) or hydrogen peroxide (0.5%).
• Remove the mask from the solution and do not wash the mask immediately but
let the hypochlorite act for about 10 minutes.
• To clean the polycarbonate screen and the mask body, use a soft cloth.
• Rinse thoroughly with running water and allow to air dry at a maximum
temperature of 50 ° C away from the sun's rays.

7 CONSERVATION, STORAGE AND TRANSPORT
7.1 Conservation

After the cleaning and disinfecting operations put the face mask into its original
packaging away from intense light, temperature extremes, humidity or altering
radiation. Avoid stacking or placing objects on top which could deform or damage
the face mask’s profile.

7.2 Storage

New, unused face masks are to be kept in their original packaging away from
excessive humidity and possibly at ambient temperature.

7.3 Transport

Keep masks in their original packaging during transport

8. MAINTENANCE, PERIODIC CHECKS, REPAIRS
8.1 Disassembly

-Unhook straps from visor frame and remove harness.
-Remove screw from bottom of visor frame and take visor out of the face blank.
-Slip  the  inner  half  mask  out  of  the  speech  diaphragm  and  the  exhalation  valve
seat and remove.
-Unscrew  the  speech  diaphragm  from  the  inside  turning  it  in  an  anticlockwise
direction  and  remove  the  internal  guard  taking  care  not  to  mislay  the  sealing  O-
rings.
-Unscrew the exhalation valve assembly from the inside turning 60° anticlockwise.
-Remove the equipment connector taking care not to misplace the O-rings.
-Clean  the  various  components,  inspect  visually  paying  particular  attention  to  the
rubber gaskets and the inhalation and exhalation valves and, if necessary, replace
damaged or worn parts.

8.2 Assembly

-Rub some silicone grease on gaskets and O-rings.
-Re-assemble the face mask following the steps at point 8.1. backwards taking
care not to damage the inhalation and exhalation valves during assembly.
-Tighten speech diaphragm and exhalation valve assembly.
