CAUTION ! - continued
A “LOW LEVEL” CONDITION CAUSES INSUFFICIENT WATER FLOW FOR
CAFSPRO OPERATION; IN TURN, REDUCING THE EFFECTIVENESS OF THE
FOAM CONCENTRATE. AN “OVERFILL” (TANK OVERFLOWS) IS VERY HAZ-
ARDOUS IN FREEZING WEATHER CONDITIONS.
1. Set the AUTOFILL select toggle switch to MANUAL (Operator Control).
The BLUE LED turns OFF.
2. Switching to MANUAL mode during operation could cause the SVS
valve to stop somewhere during its opening or closing movement, in
which case one of the three LEDs on the panel illuminates to indicate
the position of the SVS valve.
3. To generate a starting point for this valve and/or to complete an opera-
tion that was interrupted, set and hold the toggle switch to the appropri-
ate position, either OPEN or CLOSE until the appropriate LED
illuminates (GREEN or RED).
4. Carefully monitor the capacity of the tank using the Intelli-Tank 4-light
level gauge to avoid an OVERFILL or a “LOW LEVEL” condition.
Note: See the Intelli-Tank manual, p/n: 106299, for sequencing of the LEDs as
related to tank capacity.
IMPORTANT !
IN THE MANUAL MODE, THE PRESSURE SWITCH IS NOT MONITORING
INLET PRESSURE. IT IS UP TO THE OPERATOR TO ENSURE THAT THE
INLET (SUCTION) SOURCE IS AT 10 PSI (0.7 BAR) MINIMUM.
5. When tank refill is needed, hold the toggle switch in OPEN to begin fill-
ing the tank. The LEDs on the panel illuminate to indicate the position
of the valve, fully opened (GREEN)-partially open (AMBER)-fully closed
(RED).
Releasing the switch immediately STOPS the valve movement at its
present position.
6. When the Intelli-Tank 4-light level gauge indicates the tank is FULL,
CLOSE the SVS valve via the toggle switch. The red LED illuminates to
indicate the valve is fully CLOSED.
7. At the end of the operation, the setting of AutoFill (AUTO or MANUAL) is
determined by your departmental regulations or processes.
