CAUTION
RESPIRATOR SYSTEM MUST NOT BE
PRESSURIZED WHEN BATTERIES ARE BEING
INSTALLED. DAMAGE TO THE ELECTRONIC
COMPONENTS MAY RESULT IF BATTERIES
ARE INSTALLED WITH SYSTEM PRESSURIZED.
SCOTT respirators equipped with the PAK-ALERT distress alarm
require six (6) “AA” cell batteries for operation. The six (6) batteries
power the Heads-Up Display, the PASS device, and the PAK-TRACK-
ER Transmitter. The batteries should be replaced only by a trained
maintenance technician in a clean area known to be nonflammable.
NOTE
WHEN RECEIVING AIR-PAK RESPIRATORS, THE USER SHOULD UP-
DATE THE ELECTRONICS TO THE LOCAL TIME ZONE USING THE
PAK-LINK PROGRAMMER (P/N 200673-01).
Replace batteries as follows:
1. Close respirator cylinder valve, open regulator purge valve letting out
all the trapped air, close regulator purge valve, press the reset button
twice. If there is air pressure left in the system, the green ashing light will
continue to ash while a fteen second beep sequence is heard from the
Sensor Module as the residual air bleeds from the system. As soon as
the air has completely bled from system, the unit will sound a quick two
tone chirp and the PASS DEVICE distress alarm will be inactive. If there
is no pressure in the system when the RESET button is pressed twice,
there will be no beep sequence. If there is air pressure in the system, the
PASS DEVICE distress alarm will return to the active mode.
NOTE
ALWAYS BE SURE THAT CYLINDER VALVE IS OFF AND THE PASS
DEVICE IS COMPLETELY INACTIVE BEFORE CHANGING BATTERIES.
NEVER REMOVE OR REPLACE BATTERIES WITH SYSTEM PRESSUR-
IZED OR DAMAGE MAY OCCUR TO ELECTRONIC COMPONENTS.
2. When replacing batteries on respirators, remove the cylinder and place
the respirator in a clean, non-hazardous area.
3. Use a Phillips driver to remove the Battery Housing Cover as shown in
FIGURE 6. Carefully remove the cover and set aside.
4. Remove used batteries from battery compartment by sliding them out of
the battery compartment.
5. Install six (6) fresh new “AA” batteries of the same type. Always replace
all batteries at the same time.
The battery holder is marked with the style and orientation of the batteries
required. See FIGURE 7.
