Cleaning

BED CLEANING

CAUTION
Do not use harsh cleaners, solvents or detergents. Equipment damage could occur. • Do not steam clean, hose off or ultrasonically clean the bed. Do not immerse any part of the bed. The bed electrical parts may be damaged
by exposure to water. Germicidal disinfectant, used as directed, and/or Chlorine Bleach products are not considered as mild detergents. • These products are corrosive in nature and may cause damage to your bed if used improperly. If these types of products are used, ensure the beds are wiped with clean water and thoroughly dried following cleaning. Failure to properly rinse and dry the beds will leave a corrosive residue on the surface of the bed, possibly causing premature corrosion of critical components. Failure to follow the above directions when using these types of cleaners may void the product’s warranty.
Procedure:
Hand wash all surfaces of the bed with a soft cloth moistened with a solution of lukewarm water and a mild detergent. Wipe the bed clean and dry thoroughly to avoid build up of cleaning solution.

MATTRESS CARE

WARNING
Inspect the mattress after each use. Discontinue use if any cracks or rips, which may allow fluid to enter the mattress, are found in the mattress cover. Failure to properly clean the mattress, or dispose of it if defective, may increase the risk of exposure to pathogenic substances and may bring about diseases to the patient and user.
Inspection
Implement local policies to address regular care, maintenance, and cleaning of mattresses and covers. The cover • cleaning procedure can be found below and on the bed label. Inspect mattress cover surface, interior and exterior, as well as zip fasteners and cover inner surface if mattresses • have zip fasteners, regularly for signs of damage. If the mattress cover is heavily stained or soiled, or is torn, remove the mattress from service.
Cleaning
Stains: Wash with lukewarm water using a mild detergent. Rinse with water and let dry. For tough stains, use bleach diluted with ten parts of water.
