• <br />• <br />• <br />Containment Manholes <br />The Emco Wheaton A1003 <br />containment manhole is designed <br />to prevent underground pollution by <br />catching and containing product <br />spilled during product drops. <br />Spillage can be bailed out of the <br />manhole, or drained directly into the <br />underground tank through an <br />internal drain path. <br />Although the concept of a <br />containment manhole is not new to <br />the petroleum industry, the design <br />features of this manhole certainly <br />are. Please take note of these <br />special features called out below. <br />• <br />Entire unit is constructed of light- <br />weight aluminum and gas -resistant <br />plastic—extremely durable, yet easy <br />to ship, store, handle, and install. <br />Since all components of the unit <br />are internal, this manhole is the <br />one manhole that really can be <br />maintained. Other styles cannot <br />be maintained once they're <br />cemented in. <br />This manhole is compatible with all <br />Emco Wheaton coaxial or dual point <br />product drop equipment. For informa- <br />tion on how to order, contact your <br />nearest Emco Wheaton distributor. <br />Features: <br />Aluminum Lid designed to be <br />waterproof, yet light and easy to <br />remove and replace. Non -sparking. <br />Lid bearing load 7.5 ton. <br />Anchoring Bolt seals inner shield <br />and expansion joint to rim. <br />Drain Assembly latches open. It <br />cannot be left o0en or the manhole <br />lid will not fit properly. This simple <br />check was designed into the <br />system to make sure that the <br />underground tank does not vent <br />through the manhole. <br />Expansion Joint isolates riser from <br />grade. Frost heave and mild <br />siesmic shock will not rupture <br />containment manhole. <br />Large Internal Drain feature pro- <br />vides quick evacuation of product <br />and greatly reduces the possibility <br />of blockage. No external hose. <br />Body of unit threads directly on to <br />fill pipe.
