1.5.2.1 VERY IMPORTANT NOTE :-
This type of door can only be automated
with the aid of a special adaptor system,
viz., the "Vertical Track Adaptor Kit". When
fitted with a "VTAK" system, the "built-in"
overload sensors of the door operator,
regardless of make or model, may be
compromised to the extent that local safety
standards may not be complied with.
SABS-IEC Safety Standards preclude the
use of this system for the automation of
domestic garage doors.
Check with your local operator dealer for
more information.
IMPORTANT NOTES ON THE
CONDITION OF GARAGE DOORS
No door should be converted to automatic
operation unless it is in good working
order.
Before installing an automatic door
operator, inspect the door for signs of
worn, damaged or missing parts and
repair or replace as necessary. Test the
operation of the door to make sure that it
is properly balanced.
Pay particular attention to the springs.
Domestic garage door springs should be
replaced after every 10 000 operating
cycles, ( or approximately 4 to 5 years of
normal usage ).
