3 Installation
Read the chapter on safety. Check before installation if the parts are all present
and undamaged. In case of errors, contact your vendor.
3.1 Preparation
The complete wiper, with packaging, can be handled and transported by hand.
Leave the wiper in the packing, until you are ready to install it; this to reduce
the risk of damage. Make sure all parts, tools and other means are ready.
3.2 Installation of mechanical parts
1. The wipe arc of your wiper is not set. Please follow steps described in
paragraphs 5.3 and 5.4 to set the wiping arc prior to installation.
Determine the place where the wiper is to be installed. The dimensions are
shown below. The wiper can be installed in any position.

Attention!
When installing the wiper, reserve space for a housing or cover.

bulkhead.
Attention!
Do not fit the wiper arm before finishing the electrical connections.

4. Connect the wiper to the ship’s electrical installation; see the drawing above
(and the colour codes at page 19). Use a cable with 5 wires with a diameter
of at least 1½ mm2(16 g) up to a maximum length of 10 m. Use larger
diameters when using longer cables.
5. Fit a slow blow fuse of 8A (12Volt) or 6A (24 Volt) in the main cable.
6. Connect the switch to the wiper (refer to the switch manual for installation).
3.4 Final installation
7. Switch on the power and test the motor briefly. Wait until the motor stops
after turning off the switch. The motor will be in park position. The
standard park position is shown in the figure
under point 8.
Hint!
If you have doubts regarding the park position,
make a vane with tape to simulate the position of
the arms.
Attention!
The 255BS is suitable for wiper arms model P10 up
to 1000 mm and wiper-blades up to 1200 mm.
8. Place the wiper arm with the blade on the shafts. Fasten the nuts loosely
onto the shafts.

Attention
To ensure the arm has the right spring pressure, install the wiper arm in such a way
that the shaft makes a 90° angle with the window (figure left) ánd that the shaft
makes a 90° angle with the wiper arm (figure right). If this is not the case, please
install spacer(s) to make the 90° angles.
9. Switch on the power and test the motor briefly again to check the wiped
area.
10. If the wipe arc is correct, adjust the position and the length of the arm if
necessary. Tighten the nuts properly now.
