NOTES
1. Check all hoses for weak or worn
conditions after each use. Ensure that
all connections and fittings are tight and
secure.
2. 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.
3. The in-line strainer/valve assembly is a
low pressure device and WILL NOT
withstand flushing water pressure. When
installing the in-line strainer in systems
equipped with Hale MDT
ΙΙ
or Hale MST
make sure the in-line strainer/valve
assembly is in the hose on the inlet side
of the valve. If the strainer will be
subject to flushing water pressure, use
Hale FS series strainers.
4. When determining the location of Hale
Foam system components keep in mind
piping runs, cable routing and other
interferences that will hinder or interfere
with proper system performance.
5. Always position the check valve/injector
fitting at a horizontal or higher angle to
allow water to drain away from the
fitting. This will avoid sediment deposits
or the formation of an ice plug.
6. The cordsets provided with each Hale
Foam system are 100% electrically
shielded assemblies. Never attempt to
shorten or lengthen the molded cables.
If necessary order longer or shorter
cordsets from Hale Products to suit the
particular installation.
7. The cordsets provided with each Hale
Foam system are indexed so they only
go in the correct receptacle and they
can only go in one way. When making
cordset connections DO NOT force
mismatched connections as damage
can result in improper system operation.
8. The system can only perform when the
electrical connections are sound, so
make sure each one is correct.
9. 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.
10. There are no user servicable parts inside
Hale Foam system electrical/electronic
components. Opening of these
components (distribution box, control
unit, foam discharge multiplexing display
unit) will void warranty.
11. Use mounting hardware that is
compatible with all foam concentrates
to be used in the system. Use washers,
lockwashers and capscrews made of
brass or 300 series stainless steel.
12. When making wire splice connections
make sure they are properly insulated
and sealed using an adhesive filled heat
shrink tubing.
13. Before running wires from the low tank
switches to the A-B switch box make sure
the wire from Tank A is identified and
properly labeled.
14. ALWAYS connect the primary positive
power lead from the terminal block to
the master switch terminal or the positive
battery terminal using minimum 4 AWG
type SGX (SAE J1127) chemical resistant
battery cable and protect with wire
loom.
15. Prevent corrosion of power and ground
connections by sealing these
connections with silicone sealant
provided.
16. Prevent possible short circuit by using the
rubber boot provided to insulate the
primary power connection at the Hale
FoamLogix distribution box.
