uSe of The AuTomATic TrAnSfer feATure
Before entering the area requiring respiratory protection, test the Au-
tomatic Transfer feature of the SKA-PAK AT respirator as follows:
1. Breathe normally from the respirator supplied by the air supply
hose.
2. Check that the air supply cylinder gauge is reading "FULL".
3. Check that the red purge valve on the facepiece mounted regula-
tor is closed (fully clockwise and pointer on knob up).
4.
oPen The cylinder vAlve
by turning the valve knob to the
full counterclockwise position. This will require approximately 2
1
/
2
complete rotations of the cylinder valve knob. The ELECTRONIC
alarm shall flash both lights for approximately five seconds to ini-
tialize and stop. The cylinder pressure gauge on the ELECTRONIC
alarm shall read "FULL". The VIBRALERT shall NOT actuate and
breathing shall continue normally.
5. To test the Automatic Transfer, briefly disconnect the air supply
hose from the airline connection hose. The SKA-PAK AT shall
begin to supply air from the air supply cylinder and actuate the
VIBRALERT end of service time indicator.
6. Immediately reconnect the air supply hose to the airline connection
hose. Air shall be supplied to the respirator from the air supply hose
and the SKA-PAK AT shall cease supplying air from the cylinder.
The VIBRALERT end of service time indicator shall stop.
Perform
this test quickly to maintain supply of air in cylinder
.
7. If the ELECTRONIC alarm RED light begins to flash during or
after the above test, check both the gauge on the air supply
cylinder and the pressure gauge on the ELECTRONIC alarm. If
the cylinder has dropped below 90% (+/-5%) of full volume, the
ELECTRONIC alarm RED light will continue to flash. Replace the
air supply cylinder with a "FULL" cylinder before entering the area
requiring respiratory protection.
8. During use of the respirator in the hazardous atmosphere, if the
VIBRALERT actuates at any time or the ELECTRONIC alarm RED
light begins to flash, IMMEDIATELY LEAVE THE HAZARDOUS AT-
MOSPHERE AND DETERMINE THE CAUSE OF THE ALARM.
noTe
IF THE AIR SUPPLY SYSTEM IS INCAPABLE OF MAINTAINING
THE REQUIRED PRESSURE AND FLOW TO THE SKA-PAK AT, THE
VIBRALERT MAY ACTUATE INTERMITTENTLY. IF THE VIBRALERT
END OF SERVICE TIME INDICATOR ACTUATES FOR ANY REASON,
LEAVE THE HAZARDOUS ATMOSPHERE AND DETERMINE THE
CAUSE OF THE ALARM.
