Installation Recommendations; Electrical Connections - Vetus TWinlineA Instructions D'installation

1 Introduction
The VETUS extractor fan type TWinlineA / TWinlineB / TWinlineC / TWin-
lineD is intended for ventilating the engine room, toilet or kitchen.
In order to prevent personal injury, the electrical supply should always
be disconnected during installation and maintenance.
Never use the fan where the ambient temperature exceeds 70º C (158
degrees F).
We DO NOT recommend that this extractor fan is used to supply air to
the ship's engine. Any engine will be able to supply itself with air, pro-
vided the ventilation openings in the engine room are large enough.
When a fan is fitted in the engine's air supply duct, the suction of the
engine intake will make the fan run too fast, causing it to overheat.
2 Operating Instructions
The fan should be switched on for a minimum of 4 minutes and the
engine room checked for vapour before the engine is started.
NEVER switch the fan on while refuelling.

Installation recommendations

The fan can be fitted in a number of different situations.
3.1 Example 1
Here, the ship's engine does NOT obtain its inlet air separately. The
engine room can only be ventilated by the fan when the engine is
stopped. See Drawing 1.
3.2 Example 2
In this situation, the ship's engine gets its inlet air separately (via a grille
with plenum chamber). The fan is then used to extract hot air from the
engine room. this can be done while the engine is running or stopped.
See Drawing 2.
3.3 Note
Always ensure that the ventilation openings are large enough, and
that the fan(s) has sufficient capacity. Improperly positioned ventila-
tion openings and insufficient capacity fans can lead to poor function-
ing of the ship's engine. Always read the engine supplier's installation
instructions.
With a DIESEL engine , the air should preferably enter the engine room
low down, and be extracted as high up as possible.
With a PETROL engine , the air should enter from high up in the engine
room, and be extracted as low down as possible , where it is most
likely that vapour will collect. This point should always be below the
top of the engine foundation. However, the duct opening should not
be so low that there is a risk of bilge water being sucked into the fan.

4 Installation
Fit the fan in a bulkhead or floor, high enough above the bilge water
level, in a place free from splashes, drips or deck swabbing water. The
ventilator should be fitted facing downwards, to allow natural water
drainage. This will prevent water collecting in the fan.
Determine the position of the fitting holes. Use the fan as a guide. Drill
holes for 4.8 mm. (no. 10) screws. Fix the fan with the screws. Tighten
up the screws evenly.
4.1 Ventilation Duct
Fit ventilation ducting which conforms to the following requirements:
- Smooth inside
- Resistant to a temperature of at least 70º C (158 degrees F)
- Resistant to water, oil and fuel
- Resistant to under and over-pressure
with an internal diameter of: TWinlineA / TWinlineC : 76 mm (3")
TWinlineB / TWinlineD: 102 mm (4")
Keep the ventilation ducting as short as possible with as few bends as
possible. Keep the radius of any bends as large as possible.
Fit the duct with a screwing movement to the duct outlet. Fix ducting
with stainless steel hose clamps. A ridge on the duct connectors keeps
the ducting in place and ensures that they will not slide off after instal-
lation.
Fit a grille over the extractor opening when the fan does not have a
ventilation duct. This will prevent touching the revolving fan blades.

4.2 Electrical Connections

Check that the ship's voltage is the same as the voltage stated on the
fan (12 or 24 Volt).
Connect the fan as shown in the diagram, see drawing 3. Extend the
connector wires if required. The minimum core wire cross- section is 1.5
mm 2 , the insulation must be resistant to more than 70 degrees C. Fit a
4 Amp fuse in the + wire.
