Pump
For complete pump instructions refer to the pump
instruction manual included with your system.
• If necessary, change the orientation of the fluid inlet
and outlet ports on the pump. See pump instruction
manual for this procedure.
• Retorque bolts per specifications.
Air Line
Alpha letters included in the following instructions refer
to letters shown in Typical Installation examples (F
IG. 1 -
F
IG. 2, pages 4 - 5).
Locate one bleed-type master air valve (B) close to the
pump and use it to relieve trapped air (F
IG. 4). For drum
mounted installations only, also locate a second master
air valve upstream from all air line accessories and use
it to isolate them during cleaning and repair.
1. Using the hardware provided install the air controls
to the air inlet of the pump as shown in F
IG. 4. Use a
minimum 1/4 in. (6.3 mm) ID air hose.
2. Install an air line quick disconnect coupler onto the
end of the air supply line (C) and screw the matting
fitting into the pump air inlet snugly. Do not connect
the coupler to the fitting yet.
Fluid Supply Hose
Numerals used in the following instructions refer to ref-
erence numbers used in the Parts Lists provided on
pages 10 - 11.
1. Screw the fluid supply hose (9) fluid fitting into the
pump inlet snuggly. Do not overtighten.
NOTE: At the inlet, if the fluid pressure is greater than
15 psi (0.1 MPa, 1 bar) the diaphragm life will be short-
ened.
Fluid Suction Kit (6) - 24F532
Numerals used in the following instructions refer to ref-
erence numbers used in the Parts Lists provided on
pages 10 - 11.
The DEF System includes a Fluid Suction Kit containing
the following parts - Drum Coupler (6a), Drum Insert
(6b) and Suction Line (6c).
NOTE: The suction line (6c) can be used with either a
55 gallon drum or larger totes.
• If using with a large tote
: Do NOT trim the suc-
tion line.
• If using with a 55 gallon drum
: Trim the suction
line to 39 inches (991 mm). Remove all burrs.
A bleed-type master air valve (B) is required in your
system to relieve trapped air between the valve and
the pump. Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
from fluid splashing in the eyes or on skin, injury
from moving parts or contamination from hazardous
fluids.
