: Installation
Some installations may require higher flows
and larger diameter piping. Use a Hale 4
inch 2433 flange type check valve (Hale
P/N 038-1570-04-0) for these installations.
This check valve has an 8 bolt, 5-¾ inch bolt
circle and will fit pump discharge openings
and flanges that have this configuration.
The Hale 2433 check valve has a pressure
rating of 500 PSI (34 BAR) and a flow rating
of 1250 GPM (4731 LPM). The Hale 2433
style flange (Hale P/N 115-0040-00-0) has an
8 bolt, 5-¾ inch bolt circle and 4 inch NPT
threads for in-line mounting of the 4 inch
check valve.
FLUSHING WATER HOSE
Flush water connections for the Hale ADT,
Hale MDT
ΙΙ
or Hale MST must be made
using ½ inch inside diameter tubing and
appropriate fittings. The tubing and fittings
used must be capable of withstanding the
maximum fire pump discharge pressure (500
PSI (34 BAR) minimum) and should be
compatible with foam concentrates being
used in the system.
When the Hale ADT, Hale MDT
ΙΙ
or Hale MST
is installed a check valve is provided
integral to the flushing water line
connection to provide protection against
contamination of the water system with
foam concentrate.
Hale recommends the use of one of the
above selector options to provide foam
system flushing capabilities, but if the Hale
FoamLogix system is ordered with the "no
tank" option the system installer must
provide proper hose, shutoff valve, check
valves and connections for flushing water
for the system to be NFPA compliant.
Additionally, when the Hale FoamLogix is
installed without a Hale provided selector
some operating and system protection
features will not be available.
FOAM DISCHARGE DRAINS
Drains must be provided from foam
capable discharge piping components to
prevent freezing in cold weather. When
designing the drain system care must be
taken to prevent contamination of the
water system with foam and the foam
concentrate with water. Some multiple
drain systems that allow individual drain
lines to communicate also allow foam to
bypass the installed check valves causing
contamination of fire pump and the water
or foam concentrate storage tanks.
Hale has an optional 6 port drain valve,
Model MMD6 (Hale P/N 104961) that
provides individual drains with a single
control to use for applications where a
single point for multiple drains is required. If
a Hale MMD6 drain valve is not used then
individual drain lines and valves for foam
capable discharge piping are
recommended.
ELECTRICAL REQUIREMENTS
The system installer must provide the primary
power wire and a ground strap for the Hale
FoamLogix system.
Primary power must be supplied from the
main apparatus battery to the distribution
box on the foam pump and motor
assembly. The Hale FoamLogix Model 5.0
and Model 3.3 each require minimum 60
AMP electrical service.
Primary electrical power must be supplied
directly from the battery or the battery
master disconnect switch or solenoids to the
Hale FoamLogix. Other electrical
components must not be supplied from this
wire. DO NOT connect the primer and Hale
FoamLogix to the same power wire.
The toggle switch on the Hale FoamLogix
distribution box should be left in the ON
position at all times. So the Hale FoamLogix
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
