Our observations, which cover the frequency range $212-272$ GHz, encompass approximately the range $6<z<8$ for [CII] line emission and reach a limiting luminosity of L$_{\\rm [CII]}\\sim$(1.6-2.5)$\\times$10$^{8}$ L$_{\\odot}$. We identify fourteen [CII] line emitting candidates in this redshift range with significances $>$4.5 $\\sigma$, two of which correspond to blind detections with no optical counterparts.
