2. 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 is provided to separate the two foam types helping to prevent pos-
sible adverse reactions.
3. After completion of Class “B” foam operations, briefly FLUSH the foam
pump and return the Hale FoamLogix to the ready condition by returning
to the TANK “A” position and flowing a small amount of Class “A” foam
concentrate. (See Figure 5-8: “Dual Tank Selector Operating Positions,”
on page 134.)
IMPORTANT !
MAKE SURE THE HALE FOAMLOGIX DUAL TANK SYSTEM IS IN THE TANK “A”
POSITION WHEN APPARATUS IS PLACED IN THE READY CONDITION.
5.11 FLUSHING HALE FOAMLOGIX
When returning the apparatus to the ready condition after foam operations
using Class “B” foam, the Hale FoamLogix foam pump must be FLUSHED.
Some Class “B” foam concentrates deteriorate rapidly and residue cannot
be left in the lines.
Note: Approved Class “A” foam concentrates do not deteriorate rapidly like Class
“B” concentrates. As long as an approved Class “A” foam concentrate is used
and the system is operated within 10-12 weeks no flushing is required. When
Class “B” foam concentrate is used, always FLUSH the system, then switch back
to Class “A.”
See Figure 5-8: “Dual Tank Selector Operating Positions,” on page 134.
Also see Figure 5-9: “Hale MST Selector Operation” on page 136.
1. Energize the apparatus and establish water flow through a foam capable
discharge. Set the fire pump for a LOW discharge pressure, 50 to 75
PSI (3.4 to 5.2 BAR).
2. Energize the Hale FoamLogix by pressing the ON push button, allowing
foam solution to discharge.
Note: When the Hale ADT, MDT
Ι Ι or MST is in the FLUSH position the Hale
FoamLogix foam injection system runs for about twenty (20) seconds.
