FoamLogix, Model 2.1A and 1.7AHP Class “A”
Electronic Foam Proportioning Systems
12
❑
All electrical systems have the potential to
cause sparks during service. Take care to
eliminate explosive or hazardous environments
during service and/or repair.
❑
To prevent system damage or electrical
shock the main power supply wire is the last
connection made to the Hale Foam proportioner
distribution box.
❑
Release all pressure then drain all concentrate
and water from the system before servicing any
of its component parts.
❑
Do not operate system at pressures higher than
the maximum rated pressure.
❑
Use only pipe, hose, and fittings from the foam
pump outlet to the injector fitting, which are rated
at or above the maximum pressure rating at
which the water pump system operates.
❑
Hale Foam proportioning systems are designed
for use on negative ground direct current
electrical systems only.
❑
Do not mount radio transmitter or transmitter
cables in direct or close contact with the
FoamLogix control unit.
❑
Before connecting the cord sets and wiring
harnesses, inspect the seal washer in the female
connector. If the seal washer is missing or
damaged, water can enter the connector causing
corrosion of the pins and terminals. This could
resulting in possible system failure.
❑
Always disconnect the power cable, ground
straps, electrical wires and control cables from
the control unit or other Hale Foam system
equipment before electric arc welding at any
point on the apparatus Failure to do so could
result in a power surge through the unit that
could cause irreparable damage.
❑
DO NOT connect the main power lead to small
leads that are supplying some other device, such
as a light bar or siren.
The Hale FoamLogix, Models 2.1A and
1.7AHP require 40 AMP minimum current.
❑
When operating the Hale FoamLogix in
Simulated Flow mode, an outlet for the foam
concentrate must be provided to prevent
excessive pressure buildup in the discharge
piping or hoses.
❑
Make sure the foam tank and foam concentrate
suction hoses are clean before making final
connection to foam pump. If necessary flush
tank and hoses prior to making connection.
❑
Check all hoses for weak or worn conditions
after each use. Ensure that all connections and
fittings are tight and secure.
❑
Ensure that the electrical source of power for
the unit is a negative (–) ground DC system, of
correct input voltage, with a reserve minimum
current available to drive the system.
❑
The in-line strainer/valve assembly is a low
pressure device and WILL NOT withstand
flushing water pressure in excess of 45 PSI (3
BAR).
❑
When determining the location of Hale Foam
system components keep in mind piping runs,
cable routing and other interferences that
could hinder or interfere with proper system
performance.
❑
Always position the check valve/injector fitting
at a horizontal or higher angle to allow water
to drain away from the fitting. This avoids the
possibility of sediment deposits or the formation
of an ice plug.
❑
The cord sets provided with each Hale Foam
system are indexed to ensure correct receptacle
installation (they insert one way only). When
making cord set connections DO NOT force
mismatched connections as damage can result
in improper system operation.
❑
Make sure all connections are sound, and that
each connection is correct.
❑
The cables shipped with each Hale Foam
system are 100% tested at the factory with that
unit. Improper handling and forcing connections
can damage these cables which could result in
other system damage.
