Scott RIT-PAK III Operating And Maintenance Instructions Manual page 31

AFTER THE EVACUATION IS COMPLETE
1. Verify that the HIGH pressure hose coupling is clean and reinstall the dust
cap on the HIGH pressure air supply hose coupling.
2. Immediately replace the cylinder on the RIT-PAK III portable air supply with a
full cylinder. Always provide a full cylinder for the SCOTT RIT-PAK III portable
air supply rather than use the cylinder from a previous use, to ensure the
maximum transfer of air to the respirator user's SCBA. See AIR CYLINDER
REPLACEMENT section of this instruction.
IF USING THE HIGH PRESSURE AIR SUPPLY HOSE IN COLD AMBIENT
CONDITIONS, I.E. TEMPERATURES BELOW FREEZING, SEE THE USE OF THE
RIT-PAK III PORTABLE AIR SUPPLY IN LOW TEMPERATURE SECTION OF THIS
INSTRUCTION.
USE OF THE RIT-PAK III PORTABLE AIR SUPPLY
IN LOW TEMPERATURES
USE OF THE HIGH PRESSURE AIR SUPPLY HOSE IN LOW TEM-
PERATURES
Keep the HIGH pressure air supply hose coupling and the RIC UAC coupling dry
at all times. Water on either coupling may freeze preventing connection to the
RIC UAC coupling on the respirator or preventing removal of the HIGH pressure
air supply hose once connected.
If the HIGH pressure air supply hose is used to fill a respirator cylinder in tem-
peratures less than 32° F /0° C and the full respirator is then moved indoors to
warmer temperatures, the pressure in the cylinder MUST BE CHECKED FOR
EXCESS PRESSURE within two hours after the respirator is moved indoors.
Warmer ambient temperatures will cause the pressure of the air in the cylinder
to increase. If the pressure gauge on the cylinder is reading above "full," excess
pressure must be removed from the cylinders by releasing air from the respirator
with the regulator purge valve until the pointer of the gauge is reading "full."
USE OF THE LOW PRESSURE AIR SUPPLY
IN LOW TEMPERATURES
Keep the LOW pressure air supply hose couplings dry at all times. Water on either
connector may freeze preventing connection to the coupling on the respirator or
preventing removal of the LOW pressure air supply hose once connected.
Keep the pressure reducer assembly dry at all times. During operation when air is
passing through it, the reducer will naturally get cold. Water, mud, or wet debris on
the reducer may freeze and may interfere with the operation of the air supply.

WARNING
IF THE SCOTT RIT-PAK III PORTABLE
AIR SUPPLY DOES NOT PERFORM AS
DESCRIBED IN THESE INSTRUCTIONS,
REMOVE THE UNIT FROM SERVICE
AND TAG FOR REPAIR BY AUTHORIZED
PERSONNEL. USE OF IMPROPERLY
OPERATING EQUIPMENT MAY RESULT
IN FAILURE OF THE EQUIPMENT WHICH
COULD LEAD TO SERIOUS INJURY OR
DEATH.
