Wiper system
How does the air pressure-wiper system work?
The energy to work the wiper system comes from the air
pressure inside the spare wheel which has to be around 3 bar. The
pressure can not sink under 1,6 – 1,8 bar because there is a
“Minimal-Ventil” (minimal valve) which shuts automatically if the
pressure is too low. The spare wheel is always ready to be used.
The wiper system only needs: Before pumping up the spare
wheel or filling up the water in the water tank you need to unscrew
the screw connection at the spare wheel.
Steps to install
the air pressure-wiper system: 1. In the middle, 60 millimeter
in front of the windshield, you need to drill a hole with a 8
millimeter diameter for the nozzle body (Cool. 2. The standard
installed windshield wiper switch must be taken out. The
electronical connections need to be disconnected individually and be
connected to the new switch. You eventually need a flat plug for
your cable to do so. 3. The short nozzle tube (6) which is
connected to the switch has to be put through the drilled hole
from the inside to the outside. Put the nozzle body (Cool on the
outside of the hose and pull it to the inside. To secure the
tube use a screw (7). 4. The new switch (1) has to be connected
with the electronical connections which we installed in the
second step to the dashboard. For that you need to use a Rosette
(3, Some sort of screw, Phillips?) and screw on the switch
button (4). The trigger button/release button (5) need to be put
through the hole in your switch axis (2) and be secured with
pressure. 5. The water hose (9) needs to be installed in your
direction of travel and to the right of your spare wheel. It´s
important that the water can flow properly so the hose can not
be squashed. 6. The suspension bracket (13) needs to be clamped
into two mounting holes in the rim of your spare wheel. You need
to skip one of the mounting holes (picture 3). 7. You need
to fill up the water tank (12) and clamp it into the clip. The
ascending pipe needs to be put into the water tank and sealed with
the gland (10). 8. Now you need to pump up the spare wheel
to 3 bar. 9. The screw (15) at the pressure tapping hose needs
to be put on the valve of the water tank. Afterwards you need to
connect the pressure tapping hose to the spare wheel. 10.
The system is now ready to be used. To use the windshield wiper you
need to press the release button (5) and water will be splashed
onto your windshield.
With 3 Bar you can splash 10
liters of water.
Installation of the pressure tapping hose
1. On the standard installed water tank you need to unscrew
the fittings and use a screwdriver to break through the tube.
The hole needs to have a 3 millimeter diameter. The water tank
can now hold 1,35 liters instead of 0,8 liters. (Picture
down below on page 5) 2. Pump up the spare wheel to 3 bar.
3. The air extraction tube needs to be connected to the tank first
and afterwards to the spare wheel.
Note: Before you
pump up the spare wheel or fill up the water tank you need to
disconnect the screw connection.
If you need the spare wheel
to drive you need to unscrew the connections from the spare wheel
valve. The wiper system continues to work because of the water tank
pressure. |
