Make sure that the marked centre of the main cross bar (5) is positioned in the middle of the caravan.
With the main assembly is loosely fitted onto the chassis, slide the whole assembly along the chassis until the
rollers are 20mm away from the surface of the centre each tyre (Fig. 3). Two 20mm spacers (34) are provided.
It is vitally important that each roller is at exactly the same distance away from the tyre.
The whole assembly must be parallel to the caravan/trailer axle.
Slide the motor units in or out of the cross bar accordingly to ensure the roller will have the
maximum possible contact with the tread of the tyre. Ensure that the position of each motor
unit does not obstruct shock absorbers (if fitted) and that the gear cover (Fig. 4) is not too
close to the surface of the tyre/shock absorber. The minimum clearance when the motor
units swivelled in is 15mm.
Re-check that there is sufficient space available (minimal 10mm) between the top of the
motor housing and the floor of the caravan so the motors can move freely.
Fully tighten (10Nm torque) the four bolts (Fig. 1.3C) on the main cross bar and lock them by the additional
nuts.
Fully tighten the bolts on both clamping assemblies (Fig. 2.3) with a 45Nm torque.
Re-check the distance of 20mm from the rollers to the tires, the position of the aluminium rollers in addition to
the surface of the tire and finally the distance between the gear cover (Fig. 4) and the tires & shock absorbers
(>10mm). The weight of the caravan must be on the wheels when doing this. If necessary, loosen the bolts and
re-adjust the position of the assembly.
Re-check that all bolts/nuts have been tightened to the correct torque!
The main mechanical components have now been installed.
Make sure the 12 Volt supply from the battery and any 230 Volt electricity supply are
disconnected.
Remove battery cable terminals and disconnect any external electrical power before starting work.
Find a suitable place for the control unit (8), such as a storage area, under a seat or a bed. Make sure this
place is dry and close to the battery (40cm to 60cm). The control unit can be mounted vertically on a side wall
or be mounted flat. When mounted vertically, the connections must point downwards to avoid any short-circuits
by objects falling into.
Fix the control unit securely into position with two screws M5x40 (38). Note: if the provided screws are not of
suitable length or type for the desired location/material please substitute these as appropriate.
Drill a 25mm hole through the floor of the caravan approximately 150mm centrally in front of the control unit
terminals.
Caution! Take extra care to avoid any chassis members, gas pipes and electrical wires!
Route and connect the motor cables in accordance with wiring diagram (Fig. 6) (red = positive, black =
negative). In order to avoid a confusion of cables, all of the cables of motor unit B are provided with a green
stripe.
The wiring diagram (Fig. 6 & table A (see below)) depicts the wiring route when installing the motor units in
front of the wheels/axle towards the ‘A’ frame. Please refer to table B (below) for fitment of the motor units to
the rear of the axle.
