Safety provisions
The safety provisions will protect the user against contact with moving, electrical
or hot parts. Some of these have to be provided by the installer. There are several
safety provisions:
• Cover or panel (obligatory): covers moving parts and electrical connections.
The installer MUST provide a self-made cover or place the wiper behind a panel.
• Make sure the wiper has enough ventilation when placing it behind a panel or cover.
• Place a fuse (see specications) sized to protect the motor.
Safety requirements
Before the Exalto wiper is installed, we strongly recommend the following:
• Read the entire manual before installation.
• Make sure your working environment as well as the wiper parts are clean.
• Check to be sure no parts are missing or damaged.
• Use only high quality tools and have them within reach when installing.
• Handle the parts with care.
• Never install or maintain the wiper with the electrical voltage applied, unless this is
specically mentioned in the manual.
• Clear your tools after installation.

1. Introduction
With this user manual we want to guide you in the installation and use of the Exalto
windscreen wiper. Please follow all instructions and install all safety provisions.
1.1 Introduction
Exalto windscreen wipers are especially designed to keep working even with the most extreme
weather conditions at sea. All external parts are made of corrosion resistant materials. The
spindle housings with the self-lubricating bearings are made of naval brass. The wiper is
designed to be mounted through the bulkhead above or below the window. The wipe arc is
stepless adjustable from 40° to 90°. By standard the model can be supplied for a bulkhead
thickness of 35 mm and 65 mm. The matching Exalto HD1 (P10) pantograph arms have
adjustable arms between 750 and 1000 mm in length. The motor has insulated earth return.
1.2 Environmental factors
Some materials used in the construction of the wiper motor maybe harmful to the
environment (e.g. copper). These parts of the wiper may be re-used or recycled.
No harmful substances are released when using or disassembling the wiper.
1.3 Modified use and warranty conditions
All modications or defects in the product are subject to the Orgalime General
Conditions of Sale. Please contact your vendor in case of any questions or if you want
to use Exalto wipers in a non-maritime environment or other applications.

3. Installation
Before starting the installation read the chapter on safety. Check before installation that all
parts are 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 will reduce the risk of damage and
loss of parts. 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 pre-set unless specied in the order and
manufacturing process. Please follow steps described in paragraphs 5.3 and 5.4 to set
the wiping arc prior to installation.
2. Rough determination of wiping arc and wiper
blade. With this method the wiping arc and the
wiper blade length can roughly be determined.
Please contact your vendor to calculate your
conguration more accurately.
• Determine length of pantograph arm (L):
L = E + D
• Get the maximum wiped area width (W):
W = ±0.9 * GW
• Find the intersection of L en W in the diagram below;
L
D
E
GH
GW
W
H
D= distance top side
glass to center
of spindles
E= eye level
GH = glass height
GW = glass width
H= vertical displacement
L= length of arm
W= width of wiped area

3. Determine the place where the wiper is to be installed. The dimensions are shown
below. The wiper can be installed in any position above or below the window.
4. Place the windscreen wiper in the pre-drilled holes of the bulkhead (see gure).
A rubber sealing gasket must be placed at both sides of the bulkhead. Hole sizes are 2x
clearance on M20 at 60 mm centers.
• The wipe arc-line closest to the intersection, shows the wipe arc;
• Find in the table below the vertical displacement of the blade (H);
Now the wiper blade length can be calculated: Length of wiper blade = 0.9 * 2 * (E-H).

3.4 Final installation
Aention!
Do not t the wiper arm before nishing the electrical connections.
Hint!
If you have doubts regarding the park
position, make a vane with tape to
simulate the position of the arms.
1. Install the wiper switch in the dashboard.
2. Connect the wiper to the ship’s electrical
system. 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 cable lengths.
3. Fit a slow blow fuse of 8 A (12 Volt) or 6 A (24
Volt) in the main cable (positive).
4. Connect the switch to the wiper (refer to the
switch manual for installation).
1. Switch on the power and test the motor briey. Wait until the motor stops after
turning o the switch. The motor will be in park position. The standard park position is
shown in the gure under point 5.3.2.
