Place two <br />support bars across the island widthwise. (Fig. A.1) <br />A.2- Rest UniBox on top of a bed of peagravel and <br />ensure the UniBox is level. The Angled supports should <br />make contact with the support bars of the island (Fig. A.1). <br />Containment boxes are marked "A" for <br />Junction box side. Refer to dispenser manufacturers <br />Junction box position. <br />UaLj Ljff,Atl►Y■ Box should be approximately 1/4" <br />above top edge of island to allow water to drain away <br />from containment box. <br />A.3- After positioning dispenser box, secure with tie <br />wire to the island support to prevent shifting during <br />concrete pour.
