2001 and 2002
protected location with easy operator access is
the ideal installation location.
After the foam pump/motor base assembly is
mounted, remove the shipping plug in the oil fill
hole on the foam pump gear case and replace it
with the vented oil dipstick (see Figure 6).
Check the oil level by removing the vented
dipstick; make sure the oil level is to the full
mark on the dipstick. Proper oil level is also
indicated when the oil is visible in 1/2 to 3/4 of
the oil level sightglass. Add SAE 30 weight
non-detergent oil if required. Replace the
dipstick when the oil level is correct.
B. DISCHARGE RELIEF VALVE
The discharge relief valve is installed on the
outlet port of the foam concentrate pump. It is
provided to protect the foam pump from
excessive pressures. The relief valve is factory
set at 400 psi [28 BAR] (600 psi [41 BAR] for
2002HP model).

C. CAL/INJECT VALVE
The CAL/INJECT valve is mounted on the
discharge side of the foam proportioner. This
valve shall be accessible by the pump operator
during normal operations. The valve is a 3-way
directional valve that selects where the output of
the foam pump will go.
Check to make sure the valve is installed
properly. Look at the ports as you move the
handle, the flow should go from the center port
to each of the other ports.
The hose and fittings from the INJECT port to
the foam injector fitting should have
1
/2 inch
[13 mm] inside diameter and be rated at
400 psi [28 BAR] for 2001/2002 models or 600
psi [41 BAR] for 2002HP models minimum
working pressure or maximum discharge
pressure of the fire pump.
