PRINCIPLES OF OPERATION
FSI® Pneumatic showers/shelters are inflated via the use of a compressed air source/electric inflator/deflator
and inflation time is approximately 45 seconds to 5+ minutes (size of unit dependent).
Over
-
inflation of the structure is designed to be prevented via the inclusion of a pressure relief valve fitted to
the unit.
If using compressed air to inflate unit, an operator must stand by at all times and immediately
turn off compressed air source when the overpressure valve is activated as noted by the
“
hissing
”
sound of escaping air. At all times ensure the high pressure air fill hose is locked to the supplied O/D
ring on the air berm with the supplied locking wire.
The structure has reinforced air inflated berms and is usually fitted with two external zipped doors, the first is
the entrance door, and the second is the exit door at the other end as determined by on
-
scene coordinators.
To deflate the unit an inflation/deflation valve is so equipped to release the air in the structure via a quarter
turn
‘
push in
’
stem, allowing the FSI® shower/shelter to deflate. Use the supplied inflator/deflator to
’
suck
’
all
air out of the unit until flat to the naked eye. The unit can then be carefully folded, as it was received, and
packed into the carry sleeve/bag supplied for safe transportation and storage.

INFLATION: Push in and quarter turn clockwise to lock
valve open. When unit fully inflated push in and quarter
turn counter clockwise to allow valve to pop up and
close. Your shower/shelter is now ready for use.
DEFLATION: To deflate, push in and quarter turn
clockwise to lock valve open. Air will rush out and unit
will begin to deflate. Ensure the tie down ropes are used
to assist the unit in returning to the ground by pulling
them toward each other allowing the unit to collapse into
its
’
own footprint. Use the deflation end of the electric
inflator/deflator to
‘

’
the remaining air out of the
unit until flat to the naked eye. Then push in and quarter
turn counter clockwise to allow valve to pop up and
close.
