The Hydro-Wiper is a mechanical wiper system designed to fit
easily to a variety of optical instruments. Using a regular gentle
brushing action, the Hydro-Wiper keeps the optical window of the
instrument clean from bio-fouling and other unwanted deposits
such as mud. The Hydro-Wiper reduces the need for costly site
visits to manually clean the instrument, maintaining data integrity
throughout long deployments.
This manual is supplied with all standard self-contained Hydro-
Wipers and provides an overview of installation and operation. If
technical assistance is required, please do not hesitate to contact
Zebra-Tech. Our contact details are on the contact page.

1.INTRODUCTION

Your Hydro-Wiper offers the following features:
•Easy to install and simple to operate
•Ultra-low power consumption for long term deployments
•High precision wipe interval timing for minimal clock drift
during long deployments
•Adjustable wipe angle
•Customisation
•Very robust for harsh field conditions
•Brush design that has been extensively field proven in
extreme conditions around the world
•On board self-monitoring for reliable operation; if the wiper
arm is knocked in front of the instrument face, the wiper
arm automatically moves to one side.

The Hydro-Wiper is fitted with 1 meter of cable between the wiper
body and control housing as standard. However, the length of
cable required may vary depending on the type of installation.
Additional cable can be fitted at the factory when the Hydro-Wiper
is built. Please specify the cable required when ordering.
FIELDTOOL KIT
The field tool kit supplied with the Hydro-Wiper contains:
•Lid shifting tool
•Spare control housing O-ring

If you require technical assistance fitting the Hydro-Wiper to your
instrument, please contact Zebra-Tech. See contact page for our
details.
FITTINGYOUR SENSOR INTO THE HYDRO-WIPER CLAMP
ADJUSTINGWIPER BRUSH PRESSURE
The success of the Hydro-Wiper is based on the brush sweeping
lightly across the sensor window at regular intervals –it is not a
scrubbing action. If there is excessive pressure, the life of the
brush will be reduced and damage to the sensor surfaces may
occur. If the brush pressure is insufficient, contact between the
brush and optical window will be lost and fouling may develop.
There are two methods to adjust the brush pressure depending on
the orientation of the brush. Vertical brushes are for instruments
with the windows on the side. Horizontal brushes are for
instruments with optical window on top of the sensor.
1. Vertical brushes:
The brush is mounted on an adjustable arm. The length of the arm
controls the brush pressure applied to the face of the sensor. This
is generally factory set and should not need adjustment unless you
are changing sensors.
Ensure the Hydro-Wiper is switched off when manually
rotating the wiper brush.
