❑ 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 sys-
tems only.
❑ Do not mount radio transmitter or transmitter ca-
bles in direct or close contact with the Smart-
FOAM control unit.
❑ Before connecting the cord sets and wiring har-
nesses, inspect the seal washer in the female con-
nector. If the seal washer is missing or damaged,
water can enter the connector causing corrosion of
the pins and terminals. This could result 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
equip-
ment 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 ir-
reparable damage.
❑ DO NOT connect the main power lead to small leads
that are supplying some other device, such as a light
bar or siren.
❑ When operating the Hale SmartFOAM in Simulated
Flow mode, an outlet for the foam concentrate must
be provided to prevent excessive pressure build up
in the discharge piping or hoses.
❑ Make sure the foam tank and foam concentrate
suction hoses are clean before making final con-
nection 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
cor-
rect input voltage, with a reserve minimum cur-
rent available to drive the system.
❑ The in-line strainer/valve assembly is a low
pressure device and WILL NOT withstand flush-
ing 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
perfor-
mance.
❑ 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 pos-
sibility of sediment deposits or the formation of
an ice plug.
❑ The cord sets provided with each Hale Foam sys-
tem are indexed to ensure correct receptacle in-
stallation (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. Im-
proper handling and forcing connections can dam-
age these cables which could result in other sys-
tem damage.
❑ There are no user serviceable parts inside Hale
Foam system electrical/electronic components.
Opening of the motor controller or controller unit
voids the warranty.
❑ Use mounting hardware that is compatible with all
foam concentrates to be used in the system.
Use
washers, lock washers and cap screws made of
brass or 300 series stainless steel.
❑ When making wire splice connections, make sure
they are properly insulated and sealed using an ad-
hesive filled heat shrink tubing.
❑ ALWAYS connect the primary positive power lead
from the terminal block to the master switch termi-
nal or the positive battery terminal.
❑ Use a minimum 8 AWG type SGX (SAE J1127)
chemical resistant battery cable and protect with
wire loom.
❑ Prevent corrosion of power and ground connections
by sealing these connections with silicone sealant
provided.
❑ Prevent possible short circuit by using the rubber
boot provided to insulate the primary power connec-
tion at the Hale SmartFOAM motor controller.
