immediately and seek assistance.

Breathing difficulty.

Dizziness or nausea.

3.1.2 Maintenance
This section applies only to the mask itself and does not include the filters unless stated otherwise.
3.1.2.1 Shelf Life
It is recommended that the HM1400 product is fully serviceable for five years after the date of
manufacture. Manufactured date is on both the outer box and internal to the front cover on the mask
itself, below the exhale valve. After this time, it would be advisable to purchase a new mask.
It is wise to make a note of the manufactured date once the mask has been purchased, just in case the
outer box is lost or the front cover requires replacement. Shelf life may be reduced if damaged or not
adequately maintained. Replace mask immediately if damaged or showing visible signs of wear.
