HOSES and FITTINGS
Four types of hoses are supplied with the ADDP system including:
system air
supply hose, well level sensor hose, fluid intake hose
and
fluid discharge
hose
.
•
The
system air supply hose
is a
blue
3/8 inch I.D. hose with brass
MALE and FEMALE quick connects. The
system air supply hose
runs
from air compressor to the pneumatic system.
•
An
air hose socket with 1/4 inch MPT
allows the
system
air supply hose
to connect from the compressor to the
air
filter/regulator
.
• The
well level sensor hose
is a
yellow
1/4 inch I.D. hose with 1/8 inch
I.D. straight-through brass quick connect fi ings. The hose is connected
to the small quick connect on the top of the pneumatic system. The
other end of this hose is positioned in the well or tank from which
the fluid is being drawn.
• There are two
fluid hoses
, one for
intake
(ribbed), and one for
discharge
(smooth).
• The
fluid intake hose
is 1 inch I.D. or larger. With quick connect
fi ings, this hose is connected to the
DDP
and runs into the well or
tank from which the fluid is being drawn.
• The
fluid discharge hose
is 3/4 inch I.D. or larger. With quick
connect fi ings, this hose is connected to the
DDP
and runs to the
discharge point
.
• The
foot valve
placed on the end of the
fluid intake hose
keeps the
DDP
from losing prime by preventing fluid from
leaving the hose. (See Figure 2)
• The
top loading cup
placed on the end of the
fluid intake
hose
draws in hydrocarbon products. The
well level sensor
hose
is a ached to the quick connect on the
top loading cup
.
