SECTION 5 MAINTENANCE
MAINTENANCE PROCEDURES
After each use 1.
Inspect wiring, hoses, ow sensors and
connections for tightness, corrosion, leaks and.
or damage. Refer to Figure 3 on page 21.
Flush foam pump if a non-approved foam
concentrate is used. Also see appendix A, “Hale
Foam concentrate Compatibility” beginning on
page 87 for recommended foam concentrates.
Monthly 2.
Remove and clean the foam strainer screen.
Flush as required.
Monthly 3.
Verify water ow calibration.
Annually 4.
Verify foam feedback calibration.
Every two (2) months 5.
If an approved foam concentrate has been left in
the system, operate foam system to remove the
foam concentrate and prevent jelling.
FREEZE PROTECTION
Cold weather transport and cold weather storage of
FoamLogix systems:
• When transporting the completed re
apparatus from the OEM to the dealer, and
the dealer to the end-user, or, when the end-
user decides to store the nished apparatus
in an unheated area subject to below freezing
temperatures, a FoamLogix winterization
process must be used.
• Any water and/or foam concentrate that
is in the foam concentrate reservoir, foam
concentrate pump, and associated foam
system piping/tubing will freeze and then
break system components when the system
is subjected to subfreezing temperatures
commonly found in over-the-road driving
during re truck delivery and transport. The
following precautions must also be taken
by OEMs, end-users, re-sellers, re truck
dealers, transport agencies, etc., that will be
transporting and/or storing the apparatus in
below freezing temperatures:
o Drain the foam concentrate storage
reservoir in accordance with safe foam
concentrate handling practices as outlined
by the foam concentrate manufacturer. If
the foam reservoir is lled with only water,
completely drain the storage compartment
of water. After empty, close all drain valves.
o Pour in ve gallons (18.93L) of an
appropriate antifreeze solution in the foam
concentrate reservoir. Consider using an
environmentally friendly biodegradable
formulation.
o Follow the Installation and operation manual
procedure to “prime” the foam pump.
o With the apparatus re pump in gear, a
water supply established, and a discharge
hose and nozzle attached to the discharge
side of the re pump, discharge over
100-gpm (380 LPM)from a foam capable
discharge.
o Turn the FoamLogix system “on.” Depress
the “up” arrow and raise the proportioning
rate to 3.0%.
o Continue to discharge water out of the
discharge hose for one-minute.
o Shut the FoamLogix system “Off.”
o Shut off the discharge valve and shut the
re pump down. Remove the water supply
connection to the re pump.
