General Installation Information
•
The Typical Installation illustrations provided on
pages 4 - 5 are only guidelines for installing system
components. Contact your Graco distributor for
assistance in planning a system to suit your needs.
•
The letters included in the following instructions
refer to letters shown in Typical Installation exam-
ples (F
IG
. 2, pages 4 - 5). The numbers
included in the following instruction refer to the Parts
pages beginning on page 10.
•
To ensure your system is compatible with fluids
being pumped, always use genuine Graco replace-
ment parts and accessories.
•
Tighten all connections firmly to avoid air and/or
fluid leaks.
•
Storage tanks should be securely anchored to pre-
vent shifting or tipping when empty or full.
Inlet Suction Kit (sold separately)
Install inlet suction kit. See Inlet Suction Kit instruction
manual for installation instructions.
Air Line
Locate one bleed-type master air valve (B) close to the
pump and use it to relieve trapped air (F
IG
. 3). 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
. 3. 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 mating
fitting into the pump air inlet snugly. Do not connect
the coupler to the fitting yet.
NOTICE
To maintain the integrity and purity of the AUS32
(Aqueous Urea Solution 32.5%) and ensure proper
operation of equipment:
•
Once the system is assembled it must remain
sealed to insure the integrity of the fluid. Break-
ing the seal on the system can lead to fluid con-
tamination.
•
After dispensing DEF, drain all the fluid from the
nozzle, making sure it is pointing downward
when stored in the nozzle holder. DEF remain-
ing in the nozzle tip and exposed to air will crys-
tallize and can plug the nozzle.
•
DO NOT lay the dispensing nozzle on the
ground or on any surface that may contaminate
the nozzle tip and compromise the purity of the
DEF.
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.
