1. Drill a 20mm diameter hole through the cill on the centreline of the weld. The centre of this hole must be set 36mm from the inside edge of the cill.

2. Unthread the nut and capstain from the jack base. Position the base on the brickwork and pass the M16 studding through the hole in the cill. Ensure the jack is level and true resting on a sound substrate. Any packing must be done using stainless steel shims. The cill must be fixed to the brick work either side of the jack base within 150mm of the cill centreline.

3. It is important to make a good watertight seal between the M16 thread and the cill- Use an appropriate silicone sealant. Wind the nut and capstan down onto the base and position the fibre washer supplied as shown.

4. Cut the baypole to length -- ensure the cut is straight and true. For a 30mm cill, the formula is opening size (brick to brick) -- 100mm. Now locate the baypole on top of the fibre washer as shown.

5. Locate the top spreaderplate into the hole in the baypole with the fibre washer in between. You can now begin to 'jack' the pole buy using a X-head screwdriver in the capstan. You shoukld jack approximately 5mm until the bay starts to take load. Do not over tighten, simply 'take the weight'. You must ensure the pole is vertical in both planes and that the top spreaderplate is located onto a suitable surface. Packing with stainless steel shims may be required at the head - depending on substrate and its condition.
