Model PSHR 2420-2 Filter
PSHR 2420-2 pump is equipped with Racor 2 filtration
system.
Both filter housings have a differential pressure gauge. The
first filter housing contains a filter/separator cartridge. This
filter/separator cartridge provides mechanical filtration and
separates water from the fuel.
The second housing contains an absorptive cartridge. This
cartridge will absorb any remaining water and will shut off
the flow once it becomes saturated with water.
The filter housing should be periodically checked for water accumulating in the bottom of the housing. With
the pump turned off, place a container underneath the filter housing and open the drain valve at the bottom
of the housing. Drain off any water, and close the valve.
.
Replace the filter cartridges when the indicator on the differential pressure gauge mounted on the top of the
second filter housing changes from green to red (15 psi) or when there is a significant reduction in flow, or
after one year of service – whichever occurs first. Repeat for second filter if gauge shows red. Refer to the
Cartridge Replacement
procedures in
Section 6
.
Important Note
The cartridges for the two filter housing are different from each other.
Important Note
Check the bottom of the housing frequently when using fuel containing anti-icing additives.
Stagnant water in the bottom of the filter housing can absorb large amounts of anti-icing additives.
This water/anti-icing solution can disarm water-absorbing elements allowing water to pass
downstream
