2 Furlex Electric
Furlex Electric is available as a complete kit for both on-deck and through-deck installation.
The electric system is also available as an upgrade of an existing Furlex by replacing the furling line,
drum and line guard assembly with the Furlex Electric Motor unit and related parts in the Furlex
Electric Retrot pack.
Low power consumption
High eciency throughout the electric power and control system. A “sleep mode” is activated to
save power when not in operation.
Powerful enough, but with precise torque limitation.
The electric motor has a computerised controller that monitors the current draw precisely. As soon
as it reaches a pre-set level it cuts out quickly enough to avoid damage to components. The torque
level is programmed into a memory chip so that each size of Furlex Electric has the correct setting.
Resistant to the marine environment
Furlex Electric has an outer cover made of an impact- and UV- resistant composite polymer.
The worm gear is enclosed in a corrosion resistant aluminum housing. The electric motor has its
own housing which is completely sealed and individually pressure tested before delivery.
Two speed operation
A double control button makes it possible to operate the
furler with great precision in the low speed mode.
By pushing both buttons at the same time, high
speed is activated.
Locks in both directions
The worm gear is self-locking (40:1) in both directions,
which means that the sail can be furled from either
the starboard, or the port side of the boat.
Emergency operation
The worm gear has a ½” socket that can be reached
from the starboard side. Seldén’s emergency line
driver is included in the delivery kit.
Compact size -minimised weight and dimensions.
The electric motor is compact, still giving enough power.
This is made possible by raising the voltage up to 42V.
Keeping weight and the dimensions in focus during the
design has resulted in a small unit.

3.2 Installation preparation for Furlex TD Electric (Through deck)
Space requirements
Please check so that there is enough space for the installation. The dimensions are given in the
section “2.5 Technical Specication”.
Make sure that there is space for the emergency line driver.
Torque bracket installation
When reefed or under full sail, the furling prole is exposed to a twisting load from the sail.
The forestay attachment of the Furlex TDE is not designed to handle this torque load.
For this reason, the Furlex TDE has a bracket at the rear part of the housing. A torque stay shall
be tted from this bracket to the side of the hull.
Without the torque stay the forestay tting may break, possibly resulting in rig failure.
3.3 Installation of the furling system excluding the electric
motor unit
For complete or retrot installation on Furlex 204/304 systems, please see:
Above deck installation: User manual 597-132 “Furlex 204S&304S”
Below deck installation: User manual 597-418 “Furlex 204TD/304TD”
For retrot installation on Furlex 200/300 systems, please see:

3.5 Step by step assembly 204TDE/304TDE
Prior to installation, follow steps in chapter 1.4-3.2 and chapter 4 in manual
597-418. Note that more references are made to this manual during the assembly.
Protect the drum unit and motor unit by working on a clean and soft surface. 597-418-E
1.
Check that motor unit ts over hub.
Check that the two locking screws (F) t.
Note that motor unit can be turned 90°
depending on the direction of the forestay
tting in the boat. Verifying what holes are
to be used at this point will help facilitate
assembly in the boat.
Finer adjustment can be made by loosening
the locking nut (N) of the fork terminal and
turning the fork. This adjustment also aects
the distance between deck and forestay
attachment - see point 2.
Remove screws and motor unit.
2.
Fit the swivel in the boat without the motor
unit to control following points:
a) Distance between forestay tting and
deck. The distance between tack ring and
deck tting should be approx. 5mm at the
front when the eye of tack-ring is pulled
upwards. If the distance needs to be
adjusted, follow the instructions in chapter
3.2, manual 597-418
b) The position of the motor unit relative to
the fork, which determines the position of
the motor unit in the boat.
Example: if the motor unit is turned
towards portside, access to the emergency
socket will improve.
