Maintenance

All products must be installed in accordance with accepted good trade practice
(and in accordance with supplied instructions where applicable), and maintained
in accordance with these procedures or else the warranty shall be void.
AUTOMATIC CLOSERS AND OPERATORS
All Centor Architectural hardware systems are designed for manual operation.
Poorly adjusted automatic operator closers can impart significant destructive
forces to tracks, bearings and stops. Such hardware used in installations
is expressly excluded from Centor North America Inc. warranty terms.
Hardware in buildings is subject to deterioration from everyday use,
and also from environmental attack due to atmospheric and other conditions.
Maintenance of hardware is even more important in severe environments
such as coastal marine areas, and some industrial areas. Even stainless
steel products require maintenance to prevent deterioration in some environments.
Centor Architectural requires the following minimum maintenance to
be followed otherwise the warranty shall be void.
TRACK AND BEARINGS
Using a spatula or similar (not your finger), apply a small amount
(typically a 1/4 teaspoon) of white petroleum jelly (Vaseline) or similar
lubricant to the inner lip of each side of the track. Ensure that the
wheels pass through the lubricant and it is distributed evenly along
the track. Put additional lubricant around bearings. Lubricant reduces wear,
improves smoothness and further protects against corrosion of track
and bearings. Remove all surface contaminants by wiping all visible track
surfaces with a damp soft cloth and a mild detergent, then wipe clean with
a clean cloth. In severe environments, apply a thin film of a corrosion preventative
such as CRC Marine 66, Innox or WD40, by wiping with a soft cloth moistened
with one of these products.
Stainless-steel bearings are manufactured from hardening-grade stainless-steel
and although this material performs considerably better than plated
steels, it is still susceptible to corrosion unless maintained as described
above.
HANGERS, PIVOTS AND BRACKETS
A light spray application of a corrosion preventative such as CRC Marine
66, Innox or WD40, followed by a light wipe with a dry cloth to remove
excess, is recommended to all hangers, pivots and brackets. Exposed
surfaces should first be wiped down with warm soapy water and a soft
rag, and then rinsed clean before applying preventative.
HINGES
Wipe down the visible surfaces with warm soapy water on a soft rag
and then rinse off by wiping with a clean damp rag. Application of
a thin film of a light machine oil or one of the corrosion preventative
sprays mentioned above will help to maintain the original lustre of
the metal finish. Be careful not to get these compounds on the timberwork
itself as they may cause staining.
DROPBOLTS
Spray application of a suitable lubricant such as CRC Marine 66, Innox
or WD40 to the sliding pin inside the bolt and to the lock cylinder
is recommended. A tube attached to the nozzle will help to concentrate
the spray where you want it to go. There are access holes or slots
on all dropbolt products so that this can be done without removing
the locks from the doors.
SOLID BRASS
Polished solid brass is supplied as a natural, unlacquered finish.
The finish can either be left to develop a naturally aged patina or
polished with any commercial brass polish.
FREQUENCY
The procedures mentioned above need to be carried out as often as is
necessary to prevent deterioration in the installed environment, however
we recommend the following minimum frequency of application:
- general environments 6 monthly
- marine and industrial environments 3 monthly
Regular maintenance is required to all hardware, even stainless steel,
otherwise the manufacturer’s warranty may be voided.
