IMPORTANT SAFETY RECOMMENDATIONS
FAILURE TO COMPLY WITH THE FOLLOWING SAFETY RECOMMENDATIONS MAY
RESULT IN SERIOUS PERSONAL INJURY, DEATH AND/OR PROPERTY DAMAGE.
1. READ AND FOLLOW ALL SAFETY AND INSTALLATION INSTRUCTIONS
CAREFULLY.
2. The installation of your new Automatic Garage Door Opener (hereinafter referred to as
“RDO II”) must be carried out by a technically qualified or licensed person. Attempting to
install your new RDO II without suitable technical qualification may result in severe
personal injury, death and/or property damage.
3. Only install the RDO II on a properly-balanced and aligned, well-functioning garage door. An
improperly-balanced or malfunctioning garage door could cause serious injury. Have a qualified
person check, and if required, make repairs to your garage door before installing the RDO II. As
a general rule, your garage door is deemed to be well-balanced and aligned if it;
a. Requires an equivalent amount of applied force to manually open or close and,
b. Requires no more than 150N of applied force to either manually open or close and,
c. Does not rise or fall more than 100mm when stopped at any position between fully open or
fully closed positions and,
d. Does not rub on or make contact with any supporting or surrounding structures.
4. Repairs to garage doors must only be carried out by technically qualified persons. Attempting to
repair the garage door without suitable technical qualification may result in severe personal
injury, death and/or property damage.
5. Remove or render inoperative all existing locks and ropes prior to installation of the RDO II.
6. The counterbalance springs on sectional type doors must be properly lubricated between all of
the coils with heavy automotive bearing grease. Failure to adequately lubricate the springs may
result in one or more of the following symptoms;
a. The springs will become rusty over time resulting in extra operating friction between the
coils which may cause the RDO II to malfunction.
b. Seasonal temperature changes may cause the garage door springs to expand and/or contract.
The resultant increase and/or decrease in operating friction may cause the RDO II to
malfunction. Properly lubricating the springs will help to minimise the effect of seasonal
temperature changes in operating friction of your garage door.
7. If possible, install the RDO II at least 2 meters or more above the ground. Adjust the Manual
Release Cord so that it hangs approximately 1.8 meters from the ground.
8. Do not connect the RDO II to the power source until this manual instructs you to do so.
9. The RDO II must be connected to a properly-earthed general purpose 220V outlet which has
been installed by a qualified electrical contractor.
10. If one remote is to be used as a wall pendant, locate it;
a. Within site of the garage door and,
b. At a minimum height of 1.5 meters above the ground so that it remains out of the reach of
small children and,
c. Away from all moving parts of the door.
11. Install the Entrapment Warning Label in a prominent position next to the wall-mounted remote
control.
12. The Manual Release Instruction Tag must remain attached to the Manual Release Cord.
13. After installing and correctly adjusting the RDO II, the garage door must stop and reverse
direction when it comes into contact with a 35mm high solid object placed on the floor under the
garage door.

- 3 - INSTALLATION MANUAL – RDO
14. The correct function of the Safety Obstruction Reversing System should be checked on a
monthly basis. Make sure that the garage door reverses when it makes contact with an
obstruction.
15. Never use the RDO II unless the garage door is in full view and free from objects such as cars,
children and/or adults.
16. Never allow children to operate the RDO II.
17. Never operate the RDO when children/persons are under or near the path of the door. Children
must be supervised at all times when near the garage door and when the RDO II is in use.
18. Never attempt to disengage the RDO to manual operation when there are children/persons and/or
other objects including motor vehicles under or near the path of the garage door.
19. Never attempt to open or close the garage door by pulling on the Manual Release Cord.
20. Never attempt to make any repairs or remove covers from the RDO II without first disconnecting
the power supply cord from main power supply.
21. For additional safety, we strongly recommend the fitment of Safety Beams. Although the RDO II
incorporates a pressure sensitive safety obstruction system, the addition of Safety Beams will
greatly enhance the operating safety of the Automatic Garage Door and provide additional peace
of mind. In some countries, it is a mandate of law to fit Safety Beams. It is the sole responsibility
of the owner/installer to fit Safety Beams in those countries which so require.
22. Removal of the RDO II’s protective covers must only be performed by a technically qualified
person. Attempting to remove the protective covers or repair the RDO II without suitable
technical qualification may result in severe personal injury, death and/or property damage.
23. Always ensure that the garage door is fully open before driving into or out of the garage.
24. Always ensure the garage door is fully closed before leaving the driveway.
25. Adjustments to the Safety Obstruction Force settings must only be carried out by a technically
qualified person. Attempting to adjust the Safety Reverse Force setting without suitable technical
qualification may result in severe personal injury, death and/or property damage.
26. Keep hands and loose clothing clear of the garage door and product at all times.
27. In order for the Safety Obstruction Force System to function it must first encounter an
object/person on to which some force MUST be exerted. As a result the object/person/door may
suffer DAMAGE OR INJURY.
28. The Safety Obstruction Force System is designed to work on STATIONARY objects only. If
the garage door encounters a moving object during an Open or Close Cycle, serious
personal injury, death and/or property damage may occur.

REQUIREMENTS PRIOR TO INSTALLATION
A. Forward
Your RDO II is comprised of two major individual components, namely the
Drive Unit (top figure alongside) and Control Box (bottom figure alongside).
This section of the manual deals with the basic fitting requirements which should
be met before you attempt to install your opener. Study them carefully to ensure
that your door and surroundings are suitable for such an installation.
Important Note: The procedures outlined in this manual require a certain degree of
technical and mechanical skill. It is not recommended that your RDO II be installed
by a home handyman. The RDO II should always be installed, serviced and
adjusted by a technically qualified person.
B. Side Room Requirement
The recommended minimum and maximum door mounting bracket position as measured
from the edge of the garage door curtain is depicted in Fig.4. The ideal distance should
be between 85~125mm as indicated.
Important Notes:
•The fixing distance may vary from garage door to garage door
depending on the distance that the garage door drum wheel has
been set inside the garage door curtain
•If the door drum wheel has been set too deep inside the garage
door curtain, it is recommended to fit an additional drum
wheel closer to the edge of the curtain facilitating easier
installation of the RDO II unit. This product is available from
Centurion Systems (Pty) Ltd
•The installer should verify the correct distance by actually
checking the measurement prior to mounting or moving any
garage door brackets
Fig 4
C. RDO II to garage door compatibility
If, for whatever reason, the plastic forks of the RDO II do not fit into or align with the slots in the garage door
drum, or you wish to reinforce a structurally unsound drum, a special adaptor plate can be purchased from
Centurion Systems (Pty) Ltd. Instructions for the installation of the adaptor plate are included with the product.
Examples of garage door drums that would require the use of the RDO adaptor plate:
Example 1 Example 2 Example 3 Adaptor plate
Fig. 5

- 7 - INSTALLATION MANUAL – RDO
D. Check For Correct Function Of The Door
Before beginning the installation of the RDO II, check that the garage door is functioning correctly. The garage
door must be well-balanced and operate smoothly and freely. When opened to between 900~1200mm from the
floor and released, the garage door should remain in one fixed position and not rise or fall more than 100mm. It
should not bind or stick in the side tracks. The ideal operational effort required to open or close the garage door
should not exceed a force of 15kg. (Refer Item 3, Page 2)
Important Note: The RDO II must not be installed on a poorly-adjusted, worn or damaged door.
E. Weight Bar
The main purpose of the weight bar is to eliminate the possibility of the garage door curtain “ballooning” when
starting from the fully open position. With the weight bar fitted, the garage door should have a natural tendency
to lightly free fall from the mid-open position.
F. Left / Right-Hand Installation
The RDO II has been factory-set to be installed on the right-hand end of your garage door (when viewed from
inside the garage looking out). Flip dipswitch 6 to the ‘ON’ position for a left-hand installation, and to the ‘OFF’
position for a right-hand installation. Please refer to Section 13.4 for further information.
G. Control Box Location
Mount the Control Box on a smooth, flat surface. The area must be completely free from
exposure to water, either direct (rain, garden hose, sprinklers, etc.) or indirect
(seepage either through or down the internal face of the wall). The Control Box contains
sensitive electronics which will sustain damage as a result of any water ingress.
Water-damaged electronics are not covered under the terms of the opener warranty.
Important Note: The control box is not waterproof!
H. Battery Charger
The plug-in battery charger is provided to keep the batteries charged to an optimum voltage. A green coloured
LED, located on the charger casing will illuminate to indicate that the charger has been connected to an active
power supply.
Important Note: Do not mount the charger any further away from the control box than the connection
cable allows. Please ensure that a 220V mains point is provided at the control box for the charger.
I. Battery Cable Connection
In order to conserve battery power prior to installation, the RDO II is
supplied with the positive (red) battery cable disconnected from the
battery terminal.
Connect this cable as follows prior to commencing the installation;
Remove the Control Box lid and connect the red cable to the positive
(+) battery terminal as depicted in Figure 6 (Item 7).
Once connected, the lid can be refitted.

INSTALLATION INSTRUCTIONS
1. Mounting The Control Box
1.1 Establish a location at approximately chest height on the same wall face as that of the Door Mounting to which
the Drive Unit will be secured. Make sure that the cable running from the Control Box is long enough to reach up
to the Drive Unit for the location that has been selected.
1.2 Use the Mounting Template provided on Page 22 of this manual, mark the location of the three Control Box
mounting screws.
1.3 Drill a 6mm hole at each of the three marked locations to an approximate depth of 75mm.
1.4 Insert a wall plug (provided) into each of the three holes.
1.5 Insert a self-tapping screw (provided) into each of the green plugs and leave the heads exposed from the wall
(protruding approximately 6mm).
1.6 Locate the three recessed mounting slots on the center back of the Control Box base plate and “hook” the Control
Box onto the screws.Note: The mounting screws may need to be adjusted for depth if the Control Box will not
hook onto the screws or if the Control Box does hook on but is loose.
1.7 At this stage, DO NOT plug the Charger into a power socket.
2. Fitting Of Drive Unit to The Door (Right-Hand Installation Depicted)
2.1 Check that the door U-bolt is securely tightened on the opposite end of the door to which the Drive Unit will be
fitted (Fig.7)
2.2 Open the door fully and ensure that the bottom stoppers of the garage door are engaged with the stoppers on the
door guide tracks.
2.3 Place a suitable prop under the door as close to the edge (to which the drive unit is being fitted) as possible. The
prop should be adjusted so that it sits firmly under the door. (Fig.8)
2.4 Important Note: The door curtain can become damaged quite easily once the full weight of the door is
imparted on the prop. The prop must be strong enough to sustain the full weight of the door but at the
same time have enough padding that it will not damage the door curtain. The suitability of the prop should
be determined by a technically qualified person. No claims for door damage will be recognised under the
terms of the RDO II’s guarantee when using an unsuitable prop.

ensure that one of the garage door drum wheel spokes slides in between the forks of the Drive Unit.
2.10 Refit the garage door mounting bracket to the wall. The U-Bolt slots in the door bracket must align with the
U-bolt mounting slots in the Drive Unit. (Fig.10)
2.11 Important Note: In some cases the door mounting bracket may need to be repositioned in order for the
U-Bolt holes align.
2.12 Fully insert the specially supplied U-bolt through the Drive Unit and garage door mounting bracket slots.
2.13 Affix and firmly tighten the U-Bolt with the two securing nuts provided.
2.14 Check the manual operation of the door by fully raising and lowering the door. The door should run smoothly
and should not catch on any part of the Drive Unit assembly.
