� On tiled work surfaces, the joints in the area where the hob sits must be completely filled with grout. � On natural stone, synthetic stone, or ceramic surfaces, the snapaction springs can be bonded in place. � Ensure that the seal is correctly seated in the frame and that it is seated against the work surface without leaving any gaps. Please do not apply additional silicon sealant, this will make removal more difficult in the event of the need for service.
