Laguna 2.0 Patient Chair – Care and Maintenance
No maintenance is required except normal care and cleaning.
Clean vinyl upholstery and plastic components with mild soap and water.
Barrier covers should be used on chairs for asepsis.
Surface disinfecting chemical will eventually cause some discoloring of upholstery.
Suggested Disinfectant Application
Clean dirt and stains with mild soap and water.
Moisten an applicator with disinfectant; mildly wipe the material with the disinfectant.
Do not allow the disinfectant to soak in or dry on the surface; wipe off with soap and water.
PLEASE KEEP LIQUIDS AWAY FROM ELECTRICAL CONNECTIONS!
Most electrical control switches ARE NOT hermetically sealed.
When a switch gets wet, it can self-activate, or perhaps short out and damage other system
components. Keep switches dry. Avoid costly equipment damage or failure. Avoid downtime by
following these guidelines:
Please DO NOT spray disinfectants directly AT OR INTO electrical switches and controls.
Simply spray these solutions onto a cloth and wipe down the control surfaces. Be careful not to
saturate the cloth.
• Any action not recommended by the manufacture may cause risk of injury or shock!
