6. Connect a hose between the foam tank outlet and the BOTTOM of the foam
tank (Tank "A"). (See Figure 3-1: ‘Three-Position Valve Plumbing, Single Tank’
on page 11.)
The foam tank fill hose must be plumbed to the bottom of the tank to prevent
“foaming” of the concentrate.
Notes: The system installer must supply a service shut-off valve at the foam
tank. If a “Dual” Tank System is used, a second hose line must be fed from the
second 3-position valve to Tank “B.”
7. Connect a hose between the FLUSH outlet and an appropriate ground con-
tainer
(5 gallon/19 liter bucket). (See Figure 3-1: ‘Three-Position Valve Plumb-
ing, Single Tank’ on page 11.)
The flushing hose must be a minimum of 1/2” (12 mm) inside diameter.
WARNING!
FLUSHING PROCEDURES MUST MEET EPA STANDARDS (AND/OR YOUR
DEPARTMENTAL PROCEDURES) IN ACCORDANCE WITH TYPE OF FOAM
BEING USED.
3.2 ELECTRICAL
Smart-Switch Controller (SPC)
Refer to Figure 3-4: “Quick Disconnect Suction Hose Adapter Installation”
on page 13 for the suggested panel installation and cutout dimensions.
Determine a location on the operator panel of the apparatus for the smart-
switch controller. Consideration must be given for routing the interconnect-
ing cable from the controller to the EZFill pump/motor assembly and the
apparatus tank FULL level sensor.
Interconnecting Wire Harness
Before connecting the cable harness, inspect the O-ring seals of the female
connectors. If a seal washer is missing or damaged, water can enter the
connector causing pin and terminal corrosion, resulting in possible system
failure. (See Figure 3-6: “Interconnecting Harness, Single Tank,” on page
15.)
