MAINTENANCE
o Access doors should be manually operated once a year to check performance.
o Lubricate moving parts such as hinges and latches with a silicone spray lube as required
to maintain a smooth opening and closing of the door. Do not overlubricate. Do not use
regular lubricating oil that can attract dust and grit.
o Non-moving parts can be cleaned with a mild soap or dishwashing detergent and
water solution.
o Gaskets can be cleaned with a clean, damp, lint-free cloth. Do not apply mineral oils, vinyl
dressings, or other lubricants to the gasket as they can cause the gasket to break down
over time.
