General Guidelines for N95 Mask Loading
6.2.1
Instrument and Materials Compatibility
For high-‐velocity hot air (HVHA
™
) RH-‐N95 operating at 167
°
F, most of
the N95 mask/respirator filtration materials are thermally tolerant at
this operating temperature along with elastic, adhesive and nose foam
materials.
6.2.2
Loading RH-‐N95 Trays
•
Use trays provided with the RH-‐N95 that have been designed to
provide required hot airflow from all directions to N95
masks/respirators.
•
Masks/respirators are to be placed flat on the tray. Only two
molded masks may be stacked (nested) together and up to 12
Techno (Duckbill) may be nested linearly. See Section 6.3.3 for
details.
•
Masks must fit within the tray.
•
Trays must be fully inserted into the treatment chamber to
assure full airflow to the masks.
6.2.3
Before Running Your First Decontamination Cycle
•
Before turning the RH-‐N95 on, open the door and visually inspect
the heating chamber. Clean and wipe as needed with mild soap
and a damp cloth or any non-‐abrasive cleaner. Unit can be
externally disinfected with the disinfectant (avoid bleach) of your
choice.
•
Check for obstructions to air supply on back panel (clean filter and
maintained distance from wall) and interior air exhaust port.
•
Check seal around door to ensure it is clean and free of
obstructions.
•
Close the door and latch into closed position.
•
Start the unit by pressing the on/Standby button, locking the
door and initiating chamber pre-‐heat to 174
°
F (79
°
C) via the
“Start-‐Up” chamber heating sequence. (See 6.3.4.2) The keypad
WARNING – HOT SURFACES!
The RH-‐N95’s interior, doorway, and trays will be hot. Use heat-‐protective
gloves when touching hot surfaces or objects.
