SOME SPECIFIC SUGGESTED MAINTENANCE
FOR COASTAL SALT WATER AND OTHER
EXTREME ENVIRONMENTS:
Please note that the environment within one mile of a
sea coast can be extremely corrosive. Products installed
in this environment will typically deteriorate sooner than
products installed in a less severe environment.
1.
Open and close unit completely at least once a week
and inspect all surfaces. Salt and other corrosive or
abrasive materials such as sand must not be allowed
to build up on any surfaces, including all hardware
and sill. The sill and head jamb tracks should be free
from all dirt and debris. There should be no standing
water in the track in the sill. All hardware should be
intact and operating properly.
2. All surfaces must be cleaned with a mild detergent
soap and fresh water at least every month and more
frequently if necessary. After washing, the surface
should be rinsed thoroughly with clean water and
allowed to dry. For cleaning, do not use abrasive
household cleaners or materials like steel wool or
hard brushes that can wear and harm finishes. Any
glass cleaner used should not be allowed to run down
on any other surface.
3. Any breaches in the paint coating, such as scratches,
chips or areas of abrasion, must be repaired
immediately.
4. Every 3 months, thoroughly clean and dry all upper
and lower rollers and all hinges. Liberally apply
lubricant such as Teflon spray (no grease) on the
wheels and bearings of the rollers. Oil all hinges
including the hinge pin with light weight lubricating
oil or Teflon spray.
5. As with any painted surface exposed to corrosive
environments, every 6 months apply a wax to the
outside of the painted panel and painted track. If the
system includes corner connections make sure the
wax penetrates the connection joints.
