CENTURION SYSTEMS RDO II - Installation Prerequisites

- 6 -
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

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:
