13.5.2 Environmental influences
The additional tank for AUS 32 should not be
exposed to direct sunlight for a prolonged period of
time, either during transport on a vehicle or during
storage. The container is made of a high-quality
opaque plastic. In direct sunlight it can heat up
considerably, which has a negative effect on the
quality of the urea solution and can also lead to
deformation of the container.
Protect your filling station by covering it, for exam-
ple. Deformations caused by heat do not constitute
grounds for a complaint.
Ideal storage conditions for the urea solution are in
the temperature range from -5 °C to +25 °C. Above
+25 °C ammonia begins to outgas. In this case,
ensure that the environment is sufficiently venti-
lated. Below -11 °C the urea solution will freeze
and the filling station can be damaged.

Troubleshooting
(For troubleshooting at the pump, see operating instructions of the pump, section 10)
Feature
Delivery hose is leaking
The delivery nozzle
does not switch off auto-
matically or switches off
too late
The delivery nozzle
switches off constantly
Solution
•
Re-tighten hose clamp with a screwdriver.
•
Shorten the delivery hose up to the leaking point or replace it completely.
•
Check whether the delivery nozzle is encrusted and, if necessary, soak in
lukewarm water for some time
•
Fully insert the delivery spout into the tank nozzle
•
Change the position of the delivery spout in the tank nozzle
•
Pull the actuating lever only partially and thus reduce the flow rate

Maintenance
Dripping and minor leaks cannot be avoided with
urea solution. This leads to build-up of crystallised
white urea. Clean the unit, especially the delivery
nozzle, with lukewarm water if necessary. While
doing so, do not allow drinking water to get into the
container, as it does not meet the purity require-
ments.
Only demineralised water can be used to clean the
inside of the container.
Maintenance of the pump, see operating instruc-
tions of the pump, section 9.
The container and the hoses should be visually in-
spected regularly, at least once a month, for dam-
age and leaks. Defective parts must be replaced.
