CHAPTER 5
REPLACING BATTERIES
This chapter provides instructions for changing the batteries in an 3M Scott Air-Pak X3 Pro respirator with a Personal
Alert Safety System (PASS) device, also known as a distress alarm.
Before You Begin
Carefully read “
” on page ix before beginning any of the procedures in this chapter.
Because certain accessories and features require batteries for operation, always verify that this equipment and its
accessories have fresh batteries before use.
Replacing Batteries in Respirators with PASS
3M Scott Fire & Safety respirators equipped with a PASS device require 6 AA batteries for operation. The 6 batteries
power both the Heads-Up Display (HUD) and the PASS device; separate batteries in the gauge console are not
required. Only a trained operator should replace batteries in a clean, nonflammable area.
To replace the batteries
1 Close the respirator cylinder valve and open the regulator purge valve to let out all the trapped air.
2 Close the regulator purge valve.
3 Press the manual reset (yellow) button on the remote pressure gauge console twice.
A 15-second beep sequence occurs as the residual air bleeds off. The unit will sound a 2-tone chirp and the green
light will go out.
4 Remove the cylinder.
TIP
For information about changing batteries in 3M Scott Fire & Safety components or accessories, see the user
instructions provided with the components or accessories.
NOTE
Do not use tools to close the cylinder valve. Over-tightening the cylinder valve may cause damage that
could result in air leaking from the cylinder.
NOTE
Always ensure that the cylinder value is off and
PASS device
is completely inactive before changing
batteries. Never remove or replace batteries within a pressurized system, as damage to the electronic
components may occur.
