Mounting & Operations Manual
Optical Arrangement (Reflection Tube), Requirements for Installation
1. The distance between helmsmen´s eyes and mirror head should not exceed 1 m ... 1.2 m.
2. To get a picture with upright figures as required by the maritime authorities the location of the mirror head
should be in ship´s ahead direction of the helmsman´s position.
3. The recommended hight above eye level of the reflection mirror is about 10 cm.
4. There are no insulating glass panes in all reflection tubes to avoid condensation caused by the temperature
difference between wheelhouse inside and compass deck.
To prevent water from deck comming into the wheelhouse the reflection tube was extended so that it
exceeds the compass deck level by about 70mm. If water should get into the binnacle column in which ever
way clearances in the binnacle base allow the water to flow out again. Therfore please do not seal the
binnacle base against the compass deck!
5. The vertical axles of reflection tube and binnacle column have to be parallel to ensure line up of optical
components and to grant a symmetric reflection image.
6. If a higher foundation is necessary to reach a suitable iron safe distance of the magnetic compass, then the
reflection tube has to be weather protected by an protective tube to the sides. Use only amagnetic material
for this.
7. The flange of the reflection tube should be installed to the upper surface (from below) of the foundation.
8. Optional: horizontal optical by-passes are horizontal optical channels. These should be installed between
wheelhuse roof resp. deck beams and ceiling. Special instructions are attached to the delivery.
