PART 1 - ELECTRICAL ANCHOR WINDLASS
INSTALLATION
VERTICAL ELECTRIC MODELS
Windlass 1 Remove the anchor windlass from the packing case.
Installation Ensure that you have the necessary parts required to
complete your system.
There are four items to position, the windlass deck unit,
motor/gearbox, chain pipe (optional) and controls.
Remember to allow space below deck for the motor -
gearbox.
2 Position the windlass deck unit on the deck or in the
anchor well (see drawings for cut out dimensions)
such that the centre-line of the chain on the gypsy
aligns with the bow roller in a horizontal plane, and that
the vertical line is within 10 degrees of the chain gypsy.
Ensure that the chain achieves maximum contact around
the chain gypsy (i.e. at least 120 and preferably 180
degrees contact).
3 Cut and drill clearance holes in the deck for the windlass
and chain pipe, to the size detailed on the installation
template.
4 Apply bedding compound onto the joint faces to seal the
windlass and chain pipe to the deck.
5 Apply a small amount of grease to the deck unit drive shaft
before bolting the motor/gearbox into position. Ensure that
the gearbox is mounted squarely on the shaft. If the
underside of the deck is not parallel with the gearbox-
mounting flange, packing must be used to correct any
misalignment.
Wiring 6 The wiring of you unit and switch controls are shown in the
diagrams at the end of this section. Please ensure that you
follow the diagram for your system (Dual Direction or Single
Direction).
7 Mount the control box close to the motor, (within 1 meter),
preferably in a dry environment.
8 Connect the electrical cables from the control to the motor
(customer supply). Ensure that the cables are secure and
that the rubber boots are fitted before final crimping of the
terminal ends. Check that the cables are connected as per
the wiring diagram, before operating the windlass under
power.
9 Run the electrical cables from the control box to the batteries
(customer supply). Ensure that the cables are secure and
that the rubber boots are fitted before final crimping of the
terminal ends. Check that the cables are connected as per
the wiring diagram, before operating the windlass under
power.
10 Smear all terminals with grease, for extra protection against
corrosion, before fitting the rubber boots.
NOTE AIR Deck Switches
If using an AIR deck switch system. Please ensure that the
small breather hole, located on the underside of the switch
body, is kept clear and free from sealing compound on
installation.
ELECTRIC Deck Switches
Use 16/0.2 wire to connect the deck switches to the control
box.
Cable Sizes Lewmar recommend the use of the following cable sizes.
System Distance from Cable Size Wire (USA)
Battery to Motor mm2
12v 1m – 10m 35 1
10m – 15m 50 1/0
15m – 20m 70 2/0
24V 1m – 10m 25 3
10m – 15m 35 1
15m – 20m 50 1/0
Note: The windlass performance is directly related to the
cable size and its length. A voltage drop of more than 2 volts
will increase the amps required to power the motor and will
effect the performance of the unit. In all cases this will cause
the motor to overheat and in some to burn out. We
recommend the use of PVC or Butyl Rubber Insulated cable.
A larger cable will give increased performance.
The thermal cutout on the motor must be connected to the
switch wiring to protect the motor from overheating. The
Motor Warranty will be invalidated if the thermal cutout
is not connected as shown in the wiring diagrams
supplied.
Circuit Breaker The windlass circuit must be protected by a “Slow Blow”
Circuit Breaker fitted as shown in the wiring diagram
Model System Circuit Breaker Value
(Slow Blow)
3500 12v 225 Amp
(68000628)
3500 24v 160 Amp
(68000627)
Isolator Switch An isolator switch (ON/OFF) switch must be used to isolate
the unit when not in use, or when carrying out routine
maintenance to the unit.

PART 3 - HYDRAULIC ANCHOR WINDLASS
INSTALLATION
VERTICAL HYDRAULIC MODELS
Windlass 1 Remove the anchor windlass from the packing case.
Installation Ensure that you have the necessary parts required to
complete your system.
There are four items to position, the windlass deck unit,
motor/gearbox, chain pipe (optional) and controls.
Remember to allow space below deck for the motor -
gearbox and for the connection of the hydraulic lines from
the windlass to the power unit.
2 Position the windlass deck unit on the deck or in the
anchor well (see drawings for cut out dimensions)
such that the centre-line of the chain on the gypsy
aligns with the bow roller in a horizontal plane, and that
the vertical line is within 10 degrees of the chain gypsy.
Ensure that the chain achieves maximum contact around
the chain gypsy (i.e. at least 120 and preferably 180
degrees contact).
3 Cut and drill clearance holes in the deck for the windlass
and chain pipe, to the size detailed on the installation
template.
4 Apply bedding compound onto the joint faces and mount the
windlass and chain pipe with the gypsy pawl facing aft and
the chain stripper facing forward.
5 Apply a small amount of grease to the deck unit drive shaft
before bolting the motor/gearbox into position. Ensure that
the gearbox is mounted squarely on the shaft. If the
underside of the deck is not parallel with the gearbox-
mounting flange, packing must be used to correct any
misalignment.
Hydraulic 5 The Lewmar 3500 hydraulic windlass is designed
Installation to be used with Lewmar Commander power packs or
similar power packs that give the required flow and
pressure. Plan the routing of the hydraulic lines
(including case drain lines) and run them from the
hydraulic supply to the windlass motor (see hose type
recommendations).
6 Connect the hydraulic feed and return lines to the hydraulic
windlass motor, ensuring that the connections are secure
(see motor specifications). Ensure that pipe work is flushed
through to remove any dirt and debris before final connection
to the motor and power pack.
7 Connect the case drain line (see case drain line
specifications). Ensure that it is of adequate size.
8 Find a suitable position for electric safety deck
switch(es), remote control and / or toggle switch in view
of the windlass, anchor line and bow roller. Connect up
the switch wiring to the Commander system (see
Commander manual) or a suitable proprietary system
ensuring that the minimum supply is 3 amps. The
switches require a 12V or 24V DC system depending on
available supply.
9 Check correct operation of the windlass (eg up / down).
If the rotation is incorrect, swap the A + B hoses at the
motor, or swap the switch wiring, or swap the Directional
Control Valve (DCV) caps.

Hose For reliable operation and safety reasons, it is essential
Types to use the correct bore size of hose. To reduce pressure
drops in hose runs greater than 5 - 7 m it is
recommended a larger hose size is used.
The recommended hose bore sizes with their flow
requirements are given below.

4.54 litres ≈ 1 Imperial Gallon
(b) It is important that the correct hose
specification is used as this affects the
efficiency of the hydraulic motor and the
performance of the windlass.
IMPORTANT
Drain To obtain optimum shaft life a case drain line must be
Line fitted.
Min drain line bore diameter: 6mm (1/4")
Safe working pressure : 18 Bar (250 psi)
All drain lines should if possible be connected to the
reservoir separately.
Hydraulic The Lewmar Anchor Windlass hydraulic motors accept
Fittings the following fittings :
Motor ports - 1/2" BSP Female
Case Drain - 1/4" BSP Female
Hydraulic The connection of the service lines should be plumbed in
Connections as follows: -
A Case Drain Line Must Be Fitted.
