SANI-CEPTORS used as sanitary indirect waste receptors are required by modern plumbing codes in buildings where food is handled or processed such as restaurants, cafeterias, food markets and food processing plants. SANI-CEPTORS used as sanitary floor and area drains are essential in locations where human life could be endangered due to lack of sanitation such as hospitals, nursing and convalescent homes, clinic rooms and laboratories; also food processing plants such as dairies, creameries and breweries. These vital areas must be kept absolutely clean because the function which they serve is connected with the health and well-being of people. When sanitation, durability and longevity are considered, SANI-CEPTORS are the most cost effective drains for most applications.

Strainers and Buckets for A.R.C. SANI-CEPTORS are furnished in light weight corrosion resistant aluminum because dropping a heavy cast iron strainer or bucket could chip or damage the coating causing almost irreparable damage. Stainless Steel SANI-CEPTORS are furnished with SS strainers and buckets. Since there is no coating to chip or damage, this potential problem is eliminated.

SS Tops or NB Rims and Grates are available for traffic areas and indirect waste applications. Both have excellent corrosion resistant qualities and are extremely serviceable where food waste and food acids are encountered. Neither will discolor like brass or bronze and both offer a "lasting" silver appearance. The polishing of a terrazzo floor and the "scuffbuff" action of foot traffic passing over a SS or NB top will actually add to its appearance. A.R.C. SANI-CEPTORS are available with cast iron grates and tops for non-traffic areas.

The body size and depth are determined by the anticipated use. Where large flow rates are anticipated, bodies with greater capacity should be used. Where SANI-CEPTOR^® drains are used for an indirect waste application, it is important to select a body with sufficient depth to prevent splashing. The need for a large capacity sediment bucket will necessitate the selection of a deep body. Round bodies are more easily cleaned than square bodies; however, all Smith square or rectangular bodies are designed with large radius corners to facilitate cleaning.

Following are body types, options and recommendations:

1) BODY WITH ANCHORING OR SEEPAGE CONTROL FLANGE (Fig. 2). This flange rigidly anchors the body in the concrete slab. Body is provided with holes to control the seepage which occurs due to normal separation between the concrete and the SANI-CEPTOR^® body. Waterproofing membranes are used in many floors on grade. They should always be used in floors located above grade. When a membrane is used, Smith flange and optional flashing clamp (Fig. 3) must be specified. To indicate, add suffix -F-C to the selected figure number.

2) BODY WITH WIDE TOP FLANGE: Prefix DX stainless steel SANI-CEPTORS are designed for installation in wood decking over 16" C/C joists (Fig. 4). Top flange is 3/16" below drain rim and grate to accept standard thickness waterproof covering (A). Covering manufacturers require top of wide flange be installed approximately 1/8" below decking. This is accomplished automatically when using 3/4" plywood (C) which permits waterproof covering to be sloped (dimpled) toward drain grate (D). Drain flange is regularly provided with countersunk anchor holes for optional screws or bolts which can secure flange to deck. Wood screws furnished when specified (B).

Prefix DX cast iron SANI-CEPTORS are shown in this section. They are installed similar to other Prefix DX drains shown in Roof and Floor Drain Sections.

3) TRAP PRIMER CONNECTION: To indicate a trap primer connection on a Smith stainless steel SANI-CEPTOR^® body, add Suffix -P to the figure number selected. Connection is located on vertical C/L 2" above bottom of drain (Fig. 6). These connections are not recommended for A.R.C. SANI-CEPTORS because the exposed pipe threads rust causing an objectionable discoloration on the A.R.C. wall. When a trap primer connection is needed for A.R.C. application, Smith recommends the use of Auxiliary Inlet Fitting Fig. 2697 (Fig. 7).

TOP GRATES & COVERS FOR TRAFFIC AREAS
When drain tops are subject to traffic loading, they are considered floor and area drain applications. SANI-CEPTOR^® drains are regularly furnished with light duty top grates as indicated by the basic figure number. Top grates are available for medium, heavy and extra heavy duty service in accordance with ASME/ANSI recommendations shown by clicking here. To indicate optional top grates or solid covers, simply add desired suffix number.

When drains are to be installed in pedestrian traffic areas such as public walkways, tunnels, airports, bus and train terminals, public garages, shopping centers, malls, plazas, etc., particular care must be exercised in selecting a grate with ample free area for the anticipated drainage. Smith also recommends that, for this service, drains with sediment buckets and optional bottom strainers be selected. Their use will prevent many waste line stoppages.

Solid covers prevent entry of foreign materials when the drain is out of service. They are ideal in locations where use may be intermittent, seasonal or where future use is anticipated. Solid covers may be replaced with a grate at any future time or, conversely, existing drain grates may be replaced with solid covers.

TOP GRATES & COVERS FOR NON-TRAFFIC AREAS
When drains are installed in areas where they are not subject to pedestrian or other traffic, these are usually indirect waste receptor drain applications. The basic use is the receptor/body, either stainless steel or A.R.C. cast iron, less top (Fig. 11) or A.R.C. body with nickel bronze top less grate (Fig. 12). When there is danger of debris entering the receptor, the use of sediment buckets (Fig. 8C- 8F) or recessed grate (Fig. 13) should always be considered. The unique shallow design of recessed grates assures easy removal, where restricted head room precludes the use of a sediment bucket. Recessed grates should always be considered for installation beneath counters in bars and restaurants to intercept pits, bottle caps and similar debris regularly encountered in this service. The unique offset handle provided on the stainless steel models facilitates easy removal and replacement.

For applications where there is danger of someone stepping into the open top of the receptor, the Smith SANI-CEPTOR^® line includes half grates (Fig. 14) and three-quarter grates (Fig. 15) and grates with center hole (Fig. 16). These allow the indirect waste to be discharged into the open portion, preventing splashing while protecting balance of the top area with grating.

Half grates (Fig. 17) are particularly suitable for installation beneath frozen food, fruit, vegetable and meat cases. They are installed with the half grate exposed in the toe space and the indirect waste half concealed beneath the case. Smith half grates are either secured or designed to be stable. The unique stabilizing leg (Fig. 14), for example, on A.R.C. half grates prevents the half grate from sliding out of place. Angle grates (Fig. 18) are a variation for modern restaurant designs that incorporate a curb which supports "off the floor" stools and service counter. Both installations provide a sanitary floor drain accessible from the aisle for cleaning by removing the exposed grate with the indirect waste half concealed by the case or counter.

Partial solid covers are available in place of half grates, three-quarter grates and grates with center hole. They should always be used in lieu of grates when the indirect waste receptor will not be utilized as a floor drain, because they prevent the entry of foreign materials. Solid covers should also be used when the velocity of the indirect waste flow is sufficient to cause splashing up through a grate. The solid cover with center hole (Fig. 19) is particularly desirable when steam or hot water is being discharged with cabinetry installed overhead. This could result in a water vapor which can cause dry rot and mildew in the cabinetry. The solid cover condenses the vapor within the receptor, greatly reducing the potential for damage.

Hinged grates (Fig. 20) are another particularly useful variation. They permit easy access for cleaning the receptor and for emptying sediment buckets. Since the grate is permanently attached to the rim, any possibility of the grate not being replaced by maintenance personnel is eliminated.

The use of funnels on top of SANI-CEPTORS is very popular. For an illustration of the available funnels, please refer to catalog page 3-18. The Smith method of mounting the funnel allows it to be centered on the grate or placed in any other desired location. Round funnels (Fig. 23) are used for single pipe discharge. The 4" diameter is suitable for low velocity. The 6" diameter should be used where higher velocity is anticipated. Oval funnels (Fig. 24) are used for multiple pipe discharge. The 4 1/2" high models should always be used where higher velocity is anticipated.

The use of these funnels with the Smith SANI-CEPTOR^® prevents splashing of the discharged waste, allows the exposed portion of the grate to function as a floor drain and more importantly, retains the sanitary features of the SANI-CEPTOR^®. To specify, simply refer to Optional Top Grates and Covers. Then select the suffix number for the grate shown with the funnel desired.

SHAPE OF TOP GRATES AND SOLID COVERS
SANI-CEPTOR^® top shape is often influenced by the floor material surrounding the drain. Round tops are easiest to orient in many floors since they will not conflict with most floor designs or require alignment with adjacent walls. Square and Rectangular tops (Figs. 21 and 22) are particularly useful when installed in floors finished with ceramic tile or vinyl floor coverings. Rectangular tops are desirable adjacent to walls because they give the maximum amount of drainage with the minimum amount of projection into the traffic area.

Dairy drains for quarry tile floors. Quarry tile is often chosen for use in dairies, creameries, breweries and similar food processing installations because of its smooth durable surface. Milk and brewery residue retained by rough surfaces, crevices and pockets common to "regular" floor drains will soon sour. This unsanitary condition fosters bacterial growth and creates undesirable odors. Special A.R.C. coated cast iron dairy drains are available for this service. See Fig. 3110 thru Fig. 3131. When equivalent stainless steel drains are required, please select the desired drain from 3000 or 3000-NB Series and specify the flange to be 3" down from top of drain which is required for quarry tile floors. Then add suffix numbers as desired for top grates or covers and suffix -SBP for solid bottom ported bucket.
