Note
| countries with a very warm climate like The Middle East, Australien etc, is it necessary
to install the Regulator Box between the wheel housing plate and the front fender (in front
of the water container).
- Disconnect left parking light
= Loosen the bracket from the regulator box
- Exchange the hose between the safety valve and the regulator box (length 800 mm)
- Exchange the hose between the pressure valve and the regulator box (length 700 mm)
Note! The hoses cannot be joined
_ Mark the positions for the holes and drill g#8 6 mm holes in the front member (see
drawing)
= Locate the regulatorbox with a strap
- Check the drawing of the hoses as wrinkles must be avoided

9 Increase charge pressure
— Open the cover to the char: essure regulator
membrane and tension thespring (basic setting:
screw in the large ai undo. one turn)
sO that the chargiffg pressure rises to 1.15—1,20 bar.
See workshop’ manual, section 291.
— While adjusting the charging pressure by trial and
error, note if the motor “pinks” and check that the
water injection is working. If pinking occurs at
charging pressures up to 1.20 bar:
— check water injection
1. Start the motor and leave ticking over.
2. Remove the hose from the pressure sensor at the
T-piece (7) and connect instrument 8392813,
together with a suitable pump, (eg: radiator tester)
to the hose.
3. Raise the pressure, using the radiator tester, and
check that the water injection system starts work-
ing at approx. 0.7 bar.
4. Water consumption should be 150 ml/minute.
ES — If the system does not work, check that all con-
nections are correctly made.
Fit the “s'-emblem
(loosen the 9
the left)
e right of the trunk door
rbo’’-emblem and move it a bit to
The injection equipment has its own safe-guard which
operates if the water pressure falls below approx. 0,3 bar.
eg, when:
— The water container is empty
— the injection jet is blocked
— the pump has seized or is without power
In such a case the charging pressure is automatically low-
ered to an acceptable level.
ates NEN
If the injection jet (8) is only partly blocked, the safe-guard is
not triggered, but the motor starts pinking under load.
Clean the jet (8) before loading the motor heavily again, so
that sufficient water is obtained. If the water in the con-
tainer drops below a certain level the warning lamp will
light.
