Remove lateral uprights before washing. To do this: Remove the straps, making a note of their original positions. Pull on the top of the product to disengage the upper end of the lateral uprights from of their casings. Remove the uprights via the top opening. Replace after washing: Insert the hinge via the top opening, with the domed part outwards and flexed towards the back. Insert the upper and lower ends of the uprights into their casings. Check that the loops protrude properly through the openings. Replace the straps, placing strap at the back of the calf, strap at the back of the thigh and strap at the front of the thigh. Close the self-fastening tabs before washing. Machine wash at 30°C (delicate programme). If possible use a washing net. Do not use detergents, fabric softeners or aggressive products (products containing chlorine, etc.). Squeeze out excess water. Dry away from any direct heat source (radiator, sun, etc.). If the device is exposed to seawater or chlorinated water, make sure to rinse it in clear water and dry it.
