THESE INSTRUCTIONS, DO NOT USE
THE AIR SUPPLY UNLESS THERE IS
A COMPELLING REASON TO DO SO.
REMOVE THE EQUIPMENT FROM SERVICE
AND TAG FOR REPAIR BY AUTHORIZED
PERSONNEL. USE OF AN AIR SUPPLY
WITH A MALFUNCTIONING LED DISPLAY
MAY RESULT IN SERIOUS INJURY OR
DEATH.
WARNING
THE LED DISPLAY IS A CONVENIENCE
FEATURE THAT IS NOT CRITICAL TO THE
OPERATION OF THE AIR SUPPLY. IF THE
LED DISPLAY IS NOT OPERATING AS
DESCRIBED IN THIS INSTRUCTION AND
PRESSURE GAUGE AND THE REST OF THE
AIR SUPPLY IS FUNCTIONING NORMALLY,
THE USER MUST DECIDE IF THERE IS
A COMPELLING REASON TO PROCEED
WITH USE OF THE RIT-PAK III PORTABLE
AIR SUPPLY. FAILURE TO PROPERLY
ASSESS AN EMERGENCY SITUATION AND
THE OPERATIONAL CAPABILITIES OF THE
EQUIPMENT MAY RESULT IN SERIOUS
INJURY OR DEATH.
WARNING
REGULARLY INSPECT THE RIT-PAK III
PORTABLE AIR SUPPLY, INCLUDING
THE LED DISPLAY, AS DESCRIBED IN
THIS INSTRUCTION AND CORRECT ANY
DAMAGE FOUND. DO NOT SUBSTITUTE
ANY PARTS OR COMPONENTS. USE
ONLY THE BATTERIES AS SPECIFIED
IN THIS INSTRUCTION. THE FAILURE

BATTERIES, OR THE SUBSTITUTION OF
ANY OTHER COMPONENTS MAY IMPAIR
THE OPERATION OF THE UNIT AND MAY
LEAD TO A FIRE OR AN EXPLOSION
WHICH COULD RESULT IN SERIOUS
INJURY OR DEATH.
The cylinder pressure remote gauge console has an LED DISPLAY with lights to provide
a visual monitor of the air supply in the cylinder and valve assembly. The LED DISPLAY
appears across the bottom of the gauge console and uses the same sequence of lights
found on a standard heads-up display. The LED DISPLAY consists of four rectangular
lights to represent the cylinder pressure at FULL, THREE-QUARTERS, ONE-HALF, and
ONE-QUARTER. A fifth round red light indicates LOW BATTERY. The LED DISPLAY
operates as follows:
1. When air cylinder is opened, the LED DISPLAY will initialize and illuminate all
five lights for twenty (20) seconds. Operation of all five lights must be verified
every time the RIT-PAK III Portable Air Supply is used and with every REGU-
LAR OPERATIONAL INSPECTION. If the lights do not operate as described
here, do not use the RIT-PAK III unless there are compelling reasons for
using the equipment without the display lights. Remove the respirator from
service and tag for repair by authorized personnel.
THE LED DISPLAY
2. After initialization, the rectangular indicator lights will show the level of the
air supply in the cylinder as follows:
a) FULL cylinder is indicated by the two green lights glowing near the center
of the display.
b) THREE-QUARTERS cylinder is indicated by a single green light glow-
ing.
c) ONE-HALF cylinder is indicated by the yellow light flashing slowly at once
a second.
d) ONE-QUARTER cylinder end-of-service time indicator is indicated by the
red light at the far left flashing rapidly at ten times a second. WHEN THIS
WARNING LIGHT IS FLASHING RAPIDLY, THERE IS LESS THAN ONE-
QUARTER OF THE TOTAL AIR SUPPLY LEFT IN THE AIR CYLINDER.
THE BELL ALARM WILL ALSO SOUND AT THIS POINT.
3. When the batteries require changing, the round LOW BATTERY indicator at the
right of the display will light for twenty (20) seconds and then begin to flash
slowly at once a second. When the LOW BATTERY indicator is actuated, the
batteries still have sufficient life to operate the LED DISPLAY longer than the
longest duration cylinder that could be used with the RIT-PAK III Portable Air
Supply. However, the batteries must be changed immediately upon termina-
tion of use of the equipment. See the BATTERY REPLACEMENT section of
this instruction.
The LED DISPLAY is a convenience feature that is not critical to the operation of the air
supply. If the LED DISPLAY is not operating as described in this instruction and pressure
gauge and the rest of the air supply is functioning normally, the user must decide if there
is a compelling reason to proceed with use of the RIT-PAK III portable air supply.
