15.0 Maintenance
There is only one operator maintenance item for the Air Express LAL control unit (C1500). The air filter must be
cleaned every 30 days. Remove the filter (see filter removal instructions), located near the mattress hose
connector. Wash the filter with soap and water and rinse thoroughly. Allow the filter to dry completely and
reinstall. Filters that are brittle or crumble should be replaced. Replacement filters can be ordered under P/N
20228.
Failure to clean the filter can result in damage to the control unit and/or inadequate patient
support.
Periodic testing for function and/or repairs should be referred to qualified personnel in accordance with Air
Express LAL system (P1500) Service Manual. Factory repairs can be arranged through your local Plexus dealer
or by contacting Gaymar customer service at 1 800 828 7341.
