3. Use screws (2b), nuts (2e) and washers (2d) (pro-
vided) to install mounting plate to pump.

(2h). Fill bath with water. Keep nozzle bath tray filled
with water at all times.
Flushing
After initial assembly and installation, flush the entire
dispensing system by pumping 5-10 gallons of DEF
through it. This purges the system of air and insures any
impurities that may have been in the system are washed
out.
Dispose of the DEF used to flush the system using
approved DEF handling procedures. Do not return the
fluid to the drum or tote or use it in a vehicle.
Operation
Alpha letters included in the following instructions refer
to letters shown in Typical Installation examples (F
IG. 1 -
F
IG. 2, pages 4 - 5).
Priming
1. Hold dispensing nozzle (G) open while at the same
time slowly opening the pump air regulator (D) until
the pump (A) starts to cycle.
2. Allow the pump to cycle slowly until all the air has
been pushed out of the lines and the pump is
primed.
3. If the pump doesn’t prime crack the pump outlet fit-
ting and slowly run the pump until you see fluid fill-
ing the pump.
4. Then tighten the connection.
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 remaining
in the nozzle tip and exposed to air will crystallize
and can plug the nozzle.
DO NOT lay the dispensing nozzle on the ground
or on any surface that may contaminate the noz-
zle tip and compromise the purity of the DEF.
