TANK SELECTION WITH DUAL TANK
SYSTEM
The following procedures are provided for
operation of the Hale FoamLogix system
with a Hale ADT or Hale MDT
ΙΙ
Selector
installed.
CAUTION: Unless engaged in Class B
foam operations, the Hale FoamLogix
ADT toggle switch or Hale FoamLogix
MDT
ΙΙ
selector handle must be in the
TANK A position. If the toggle switch or
selector handle is in the FLUSH position
when the Hale FoamLogix foam pump is
started the foam pump will only run for
20 seconds and shut down.
1. Make sure the Hale FoamLogix is
operating and foam solution is being
discharged.
2. Flip the Hale ADT toggle switch down or
turn the Hale FoamLogix MDT
ΙΙ
handle until
the indicator points toward the desired tank
(See figure 4-10). When changing toggle
switch or selector handle position, move
smoothly from the TANK A position through
the FLUSH position to TANK B position in one
motion without stopping. With the fire
pump discharging water and the Hale
FoamLogix operating, a small volume of
water will be provided to separate the two
foam types helping to prevent possible
reactions.
