4) 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.
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.
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.
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.
hose is a ached to the quick connect on the top loading cup.
