Installation Guide：

    1. Locating
    It is better to locate near the ridge of a house, put the waterproof basic board on the roof of the house and embed the upward edge of basic board into the gap under metal cover about 10cm.

    2. Hole cutting
    Take the interior hole of waterproof basic board as a sample to contour the hole and cut it by professional machine; cut the heat preservation cotton as the grapheme of 米 and take it away; put the well-cut cotton and the aluminum foil into the place between steel panel and the heat preservation cotton.

    3. Waterproof adhesive tape & Waterproof silica gel sticking
    Stick the waterproof adhesive tape to the juncture between the waterproof basic board and the ridge cover, onto the top of wave crest in both sides also; Stick waterproof silica gel between closure strip and skylight panel and tear the paper on surface.

    4. Waterproof basic board fixing
    Fix the waterproof basic board onto the roof by at least 10 bolts or rivets 

    5. Install the tube which has spin angle
    Place the tube with spin angle on basic board, turn the spin part of tube and adjust it by gradienter upon 90 degree to make the top of tube level; then mark the top & bottom spin parts and the place between the tube and basic board

    6. Fix the tube
   Fix the tube on basic board by at least 4 bolts, fix the top and bottom spinning parts of the tube by metal splint and rivet according to the mark made in step 5.

    7. Fix the turbine onto the tube
    Put the 4 supporting bracket of turbine into the groove and fix the turbine onto the tube by 4 bolts.

    8. Examination & Adjustment
    First check the bolt and rivet are fixed or not; whether the turbine can spin stably or not since it may has little variation of shape because of extrusion and adjust if necessary; then stick waterproof silica gel on closure strip and around basic board.
