: Installation
master disconnect switch or solenoids to the
Hale FoamMaster. Other electrical
components must not be supplied from this
wire. DO NOT connect the primer and Hale
FoamMaster to the same power wire.
The toggle switch on the Hale FoamMaster
distribution box should be left in the
ON
position at all times. So the Hale
FoamMaster system is ready for immediate
operation when the operator places the
apparatus in pump mode, and to prevent
battery power drain when the apparatus is
not running, the primary power connection
must be made so power is supplied to the
Hale FoamMaster when the main
apparatus electrical system is energized.
Use of a solenoid with a 200 AMP peak, 100
AMP continuous rating is recommended.
With Hale FoamMaster Model 5.0 or Model
3.3, cable lengths up to 6 feet (1.8 meters)
require minimum 4 AWG type SGX (SAE
J1127) battery cable. Use solder lugs on
cable ends with a 5/16 inch (8 mm)
diameter hole. For Hale FoamMaster Model
3.0 or cable lengths greater than 6 feet (1.8
meters) refer to the following table for the
recommended battery cable size for Hale
FoamMaster system primary power wiring.
When planning cable runs make sure the
primary wires are routed by the shortest
most direct route.

A braided flat ground strap is required for
the ground connection to limit the RFI/EMI
interference encountered with radios,
computers or other sensitive electronic
equipment. The ground strap should be a
minimum of 1-¼ inches (32 mm) wide and
be no longer than 18 inches (457 mm) long.
The ground strap must have soldered flat
lug ends with 5/16 inch (8 mm) diameter
holes. If the ground strap length exceeds 18
inches (457 mm), a wider ground strap
should be used or use a double thickness of
1-¼ inches (32 mm) wide ground strap.
When making the ground strap connection
make sure the connection is made to the
chassis. Use minimum 5/16 inch (8 mm)
diameter bolt or mounting stud for this
connection.
Make sure the ground is attached directly
to the chassis frame not the apparatus
body work. Before making ground
connection remove all paint, grease and
coatings from the connection area. After
making connection seal against corrosion.
NOTE:
When an inline current shunt
ammeter is installed on the apparatus or
the Hale FoamMaster is used with
Multiplexing Display Units with multiple water
flow meters it is necessary to install a
FoamMaster power filter kit (Hale P/N 546-
1870-00-0) on the Hale FoamMaster foam
pump.
FOAM CONCENTRATE TANK(s)
Foam concentrate tank(s) must be supplied
to suit the capacity required for the
apparatus application. The tank(s) must
meet NFPA minimum standards for their
design capacity, including filler size, vapor
pressure venting, baffling and drain
facilities. The following table lists
recommended foam tank capacities for
the different Hale FoamMaster models
based on NFPA requirements for flammable
liquid (Class B) fire suppression.
