8. Fig. B: After the Mover is positioned in the correct position,
the 4 stop blocks should be bolted onto the chassis immedi-
ately behind and in front the mounting brackets (17 mm AF to
28 Nm). The stop blocks ensure that the Mover does not move
along the chassis during operation.
9. Fig. E: Now that the Mover is fitted and secured correctly,
take the remaining tubes for the cross actuation and fit as illus-
trated. The sliding centre tube will allow the width to change to
suit the caravan’s chassis. The outer tubes must be secured on
each side with the 4 grub screws provided.
Installation of motor cables and control unit
Remove battery cable terminals and disconnect any ex-
ternal electrical power before starting work. If you are
unsure about the electrical installation, have it checked out by
a qualified Auto Electrician.
Pre-fitted, each motor has four heavy-duty cables (2 x 4 mm
2
and 2 x 1 mm
2
). All the cables have to be routed along the un-
derside of the caravan floor to the point where the electronic
control unit will be situated. A recommended location for in-
stallation of the control unit is in a bedding locker close to bat-
tery and Mover locations.
The battery connection cables may not be lengthened.
1. Fig. F: Fit the control unit onto the floor of the bedding
locker with screws provided.
2. Drill a 25 mm hole, approximately 150 mm in front of control
unit for the motor cables. (Note: Take care to avoid any chas-
sis members, gas pipes and electrical wires).
3. Route the motor cables along the underside of the caravan
to the point where the control unit is located. The cabling can
be secured using the „P“ clips/screws and metal spring clips
provided. Take care to secure the cables so they will not chafe
on the chassis or sag below the floor (use supplied protection
tubing). Note: The motors move when the drive rollers are
engaged, so allow a little slack at the motors to avoid the
cables being stretched.
4. Fig. F and G: Connect the battery cables (6 mm
2
) to the ex-
isting battery connections (red = positive, black = nega-
tive). Fix the battery cables securely from the battery connec-
tors to the control unit, using „P“ clips and screws. Note: Be
particularly careful that the main battery cables will not chafe -
particularly if passed through drilled holes in metal clad bulk-
heads. Use water type tubing or a bush to prevent damage to
the cables.
5. Bring the motor cables to the entry side of the control unit.
Note the identity of each cable in turn and cut to length. On
the 4 mm
2
cables crimp the provided spade connectors to the
bared cable ends (fig. H) and connect as illustrated (red = pos-
itive: black = negative). The 1 mm
2
cables are to be connect-
ed to the plug connector (observe left and right, no need to be
concerned about polarity).
Excess cable must be cut to length and not looped inside
the bedding locker. A good quality connection on each
cable is essential!
Complete all cable terminations from the motors and battery
terminals, depending on the installation behind or in front of
the axle.
6. Ensure all electrical connections are sound and safely
clipped in place using „P“ clips provided.
Commissioning the Mover
1. Ensure the battery used to operate the Mover is fully
charged (do not operate the Mover if the voltage in the battery
is below 10.2 V DC).
2. Place the caravan outside in a clear area and pull on the
handbrake. Ensure that the rollers are disengaged from the
road tyres and the corner steadies are raised.
3. Connect battery terminals to battery, check that all cables
are secure and not hot or indicating signs of short circuits, etc.
4. Press the red button on the handset twice within one sec-
ond. This will switch on the handset and illuminate the handset
light. If the lamp does not illuminate, check the handset batter-
ies polarity and condition. The handset will switch itself off af-
ter 40 seconds if no buttons are pressed.
5. Check that both drive motors are stationary. With the hand-
set switched on, and within 2 m of the control unit, press the
forward button. Check that both drive motors are driven.
6. Press the red button again to switch off the handset and
Mover.
7. Engage the drive rollers by use of the 19 mm AF wrench
provided or the steady leg brace. The action will be quite stiff
and will snap into place. The movement required is just over
1/2 turn. Turn the wrench until it will turn no more without ex-
cessive force. This action can be done on any side of the cara-
van and will engage both sides.
8. Ensure there are no obstructions around the caravan. Re-
lease the handbrake and switch on the handset. Now check all
functions several times according the operating instructions.
9. Press the red button again to switch the handset and Mover
off. Release the drive mechanisms with the wheel brace (19 mm)
and recheck the roller to tyre spacing. Adjust if necessary.
15 mm is the minimum distance that the Mover roller
should be from the tyre.
