Installer Supplied Parts
The Hypro High Pressure System is provided with the
major components and accessories required for installa-
tion. Due to differences in chassis and apparatus configura-
tions, the installer must provide plumbing to satisfy individ-
ual installation requirements. The following paragraphs list
the specifications for selection of these components.
Before beginning system installation, read this section thor-
oughly to make sure the proper components are selected.
For detailed system installation instructions, refer to Pages
5 and 6.
Suction Lines
Corrosion-resistant fittings and hoses from the foam tank to
the foam concentrate inlet of the pump must be used. Use
5/16-inch minimum inside diameter hose for the foam inlet.
Corrosion-resistant fittings and hoses from the water
source to the inlet of the pump must be used. Use only 3/4-
inch minimum inside diameter hose for the water inlet. Use
components that are rated for 23 in [584.2 mm] Hg vacuum
and 50 psi [3 bar] pressure or greater for all suction line
inlets. The components used must be compatible with all
foam concentrates to be used. All fittings used must be
made of brass, 300 series stainless or other corrosion-
resistant materials. Before selection of components, check
for compatibility with foam concentrate. The use of clear
suction hose is recommended to allow viewing of foam and
water priming operations. The pump must be positioned to
allow gravity feed from the foam tank and water source or a
net positive suction head (NPSH) is required.
Discharge Lines
Fittings and hoses from the foam solution discharge of the
pump to the foam spray nozzle must be supplied by the
installer. Hose end fittings on gun and pump are 1/2-inch
[12.7 mm] NPT. Hose lengths and sizes are shown below.
All hoses must be rated for 1800 psi [124.1 BAR] minimum
working pressure. Fittings and hoses must be compatible
with all foam concentrates to be used. Use fittings of brass,
300 series stainless or other corrosion-resistant material
that is compatible with foam concentrates to be used.
Thermal relief valve must be plumbed to discharge away
from operator.
Check Valves
Check valves have been included with the system at the
water inlet to help prevent back flow of foam concentrate or
foam solution. The system should be disconnected from
exterior water supplies when not in use. A complete system
flush should be performed before storage to prevent com-
ponent failure due to evaporation of foam and water within
the system.
Foam Concentrate Tank
A foam concentrate tank must be supplied to suit the
capacity required for the apparatus application. The tank
should meet NFPA minimum standards for the design
capacity, including filler size, venting and drain facility. A
shut-off valve is recommended to allow cleaning of the
strainer.
Electrical Requirements
Electrical wiring must be supplied to the engine starter
switch. SEE ENGINE MANUAL for detailed electrical hook
up specifications.
CAUTION: Always disconnect ground before electrical
arc welding on any Hypro equipment. Failure to do so
will result in a power surge through the system that
could case irreparable damage to the electronic com-
ponents.
