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 re-
sistant 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 be-
low the window. The wipe arc is step less adjustable from 45° to 90°. By standard the
model can be supplied for a bulkhead thickness of 35 mm and 65 mm. The matching
Exalto MD1 Pendulum arms have adjustable lengths between 300 mm and 750 mm
in length (suitable for wiper blades upto 750 mm). The wiper arm 2143.1000B is suita-
ble for length between 750 mm and 1000 mm in length and suitable for wiper blades
850-1000 mm. 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 Modied use and warranty conditions
All modications or defects in the product are subject to the Orgalime General Con-
ditions 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 manu-
facturing 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;

Determining the vertical displacement of the wiper blade
Wipe arc
Vertical displacement of the blade (H)
Units in mm
Now the wiper blade length can be calculated: Length of wiper blade = 0.9 * 2 * (E-H).
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.
Attention!
When installing the wiper, reserve space for a housing or cover.
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. A second-
ary xing is required and we advise to bond or mechanically install a secondary
xing at the opposite end of the housing.

Attention!
Do not t the wiper arm before nishing the electrical connections.
3.3 Electrical installation
1. Install the wiper switch in the
dashboard.
2. Connect the wiper to the
ship’s electrical system; see
from page 18 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 cable lengths.
3. Fit a slow blow fuse of 8A (12 Volt) or 6A (24 Volt) in the main cable (positive).
4. Connect the switch to the wiper (refer to the switch manual for installation).
3.4 Final 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 posi-
tion is shown in the gure under point 5.3.2.
Hint!
If you have doubts regarding the park position,
make a vane with tape to simulate the position
of the arms.
