To use the RIT-PAK III portable air supply with a RIC UAC system, proceed
as follows:
1.
To prevent a loss of air from the cylinder when the valve is opened, verify that
nothing is installed on the LOW pressure air supply hose that would deplete
the air supply when the cylinder valve is open. (See the LOW PRESSURE
AIR SUPPLY USAGE section of this instruction).
2.
Fully open the cylinder valve on the SCOTT RIT-PAK III portable air sup-
ply.
3.
Before connecting to respirator user, ensure that SCOTT RIT-PAK III portable
air supply is secured on a flat, level surface where the unit will not shift or
slide. Avoid direct contact with fire or flame or other sources of heat.
4
Handle the HIGH pressure air supply hose in a manner which will prevent a
sudden or unexpected pull from moving or damaging the SCOTT RIT-PAK III
portable air supply.
5. Identify the RIC UAC coupling on the respirator user's SCBA and remove the
protective cap from the RIC UAC coupling. If the RIC UAC coupling on the
respirator appears damaged, do not attempt to connect the RIC UAC airline
assembly to the respirator. Find an alternate method of supplying air to the
respirator user.
6.
A member of the Rapid Intervention Crew/Company must visually inspect
the user's respirator before proceeding with recharging. Inspect the user's
cylinder for dents or gouges in the metal or fiber wrapping and inspect the
cylinder valve for signs of damage. If the cylinder and valve assembly shows
damage or evidence of exposure to high heat or flame, such as paint turned
brown or black, decals charred or missing, gauge lens melted or elastomeric
bumper distorted, the decision must be made whether the cylinder is suitable
for recharging by this method. Also inspect the user's respirator for other
damage to hoses or components that might result in a failure when high
pressure air is introduced into the system. If there is any suspicion that the
cylinder or the respirator is not safe, find another method of supplying air to
the respirator user.
7. Determine the maximum capacity of the user's respirator cylinder and check
the cylinder gauge on the respirator cylinder to determine how much air is left
in the cylinder. NEVER CHARGE A CYLINDER TO MORE THAN THE RATED
PRESSURE MARKED ON THE CYLINDER.
8.
Verify that the respirator user's air supply cylinder is properly installed with
the cylinder coupling connected to the cylinder to prevent any loss of breath-
ing air when the SCOTT RIT-PAK III portable air supply is connected.
9.
Verify that the cylinder valve on the respirator is fully open by turning the
cylinder valve knob fully counterclockwise (approximately 2 1/2 full turns).
10. Remove the dust cap coupling on the HIGH pressure air supply hose. Visually
inspect the coupling for dirt or damage. Remove any dirt or contamination
from the coupling.
11. Connect the HIGH pressure airline hose by pushing the quick disconnect
coupling on the hose assembly on to the RIC UAC coupling on the respirator
until the quick disconnect sleeve "clicks" into place. Check the engagement
by tugging on the coupling. See FIGURE 29.

WARNING
IF THE SCBA OR THE CYLINDER TO BE
CHARGED IS KNOWN OR SUSPECTED
OF HAVING BEEN DROPPED, EXPOSED
TO DIRECT FLAME IMPINGEMENT OR
DAMAGED IN ANY WAY, DO NOT USE
THE RIC UAC SYSTEM. FIND ANOTHER
METHOD OF SUPPLYING BREATHING AIR
TO THE RESPIRATOR USER. ATTEMPTING
TO FILL A CYLINDER WHICH IS KNOWN
OR SUSPECTED OF DAMAGE IN ANY
WAY MAY RESULT IN CYLINDER FAILURE
WHICH COULD CAUSE SERIOUS INJURY
OR DEATH.
WARNING
WHEN SUPPLYING AIR TO A RESPIRATOR
USER WITH THE SCOTT RIT-PAK III
PORTABLE AIR SUPPLY, VERIFY THAT
THE RESPIRATOR USER'S AIR SUPPLY
CYLINDER IS PROPERLY INSTALLED
AND CONNECTED TO THE RESPIRATOR
CYLINDER COUPLING. FAILURE TO
VERIFY THIS CONNECTION MAY RESULT
IN LOSS OF BREATHING AIR FROM THE
RIT-PAK III PORTABLE AIR SUPPLY, THE
USER'S RESPIRATOR OR BOTH WHICH
MAY RESULT IN UNEXPECTED LOSS OF
THE AIR SUPPLY TO THE USER OF THE
RESPIRATOR AND LEAD TO SERIOUS
INJURY OR DEATH.
WARNING
FAILURE TO CHECK ENGAGEMENT OF
THE COUPLING AS DESCRIBED MAY LEAD
TO HOSE SEPARATION AND LOSS OF
BREATHING AIR RESULTING IN SERIOUS
INJURY OR DEATH.
