SAFETY
Hale FoamMaster systems are designed to provide reliable and safe foam concentrate
injection. Before installing or operating a Hale FoamMaster 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 FoamMaster 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
FoamMaster 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 FoamMaster
system be careful of rotating
components.
CAUTIONS
1. Foam tank low level sensors must be
utilized to protect the Hale FoamMaster
from dry running. Failure to use low level
sensors with the Hale FoamMaster
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 FoamMaster 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 Hale FoamMaster unit.
6. Before connecting the cordsets 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 FoamMaster 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 FoamMaster Model 3.3 and
Model 5.0 require 60 AMP minimum
current. The Hale FoamMaster Model
3.0 requires 40 AMP minimum current.
Use correct gauge wire as specified.
9. When operating the Hale FoamMaster 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 Hale FoamMaster ADT
toggle switch or Hale FoamMaster MDT II
selector handle must be in the
TANK A
position. If the toggle switch or selector
handle is in the
FLUSH
position when the
Hale FoamMaster foam pump is started
the foam pump will only run for 20
seconds and shut down.
