SAFETY
Hale FoamLogix systems are designed to provide reliable and safe foam concentrate
injection. Before installing or operating a Hale FoamLogix system read all safety
precautions and follow carefully to ensure proper installation and personnel safety.
WARNINGS
1. Do not permanently remove or alter any
guard or insulating devices or attempt to
operate the system when these guards
are temporarily removed.
2. To prevent electrical shock always
disconnect the primary power source
before attempting to service any part of
the Hale Foam system.
3. All electrical systems have the potential
to cause sparks during service. Take
care to eliminate explosive or hazardous
environments during service/repair.
4. To prevent system damage or electrical
shock the main power supply wire will be
the last connection made to the Hale
Foam proportioner distribution box.
5. Release all pressure then drain all
concentrate and water from the system
before servicing any of its component
parts.
6. Rotating drive line components can
cause injury. When working on
components of the Hale Foam system
be careful of rotating components.
CAUTIONS
1. Foam tank low level sensors must be
utilized to protect the Hale Foam
proportioner from dry running. Failure to
use low level sensors with the Hale Foam
system will void warranty.
2. Do not operate system at pressures
higher than the maximum rated
pressure.
3. 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.
4. Hale Foam proportioning systems are
designed for use on negative ground
direct current electrical systems only.
5. Do not mount radio transmitter or
transmitter cables in direct or close
contact with the FoamLogix control unit.
6. Before connecting the cordsets 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
resulting in possible system failure.
7. 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.
8. 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 Model 3.3 and
Model 5.0 require 60 AMP minimum
current.
9. When operating the Hale FoamLogix in
Simulated Flow mode an outlet for the
foam concentrate must be provided to
prevent excessive pressure buildup in
discharge piping or hoses.
10. Unless engaged in Class B foam
operations, the ADT toggle switch or
MDT II selector handle must be in the
TANK A or FLUSH position. If the toggle
switch or selector handle is in the FLUSH
position when the Hale Foam system
foam pump is started the foam pump
will only run for 20 seconds and shut
down.
11. 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.
