SEZ SERIES COUNTERTOP STEAMERS INSTALLATION

Step 3: Drain Connection

The drain outlet is located on the back of the steamer, as shown in Figure 4 on page 9. The drain connector on the unit is 3/8" NPT male.

Position the unit near, but not on top of, an open floor drain. DO NOT directly plumb to the unit unless you also install an “open funnel” downstream of this connection in the drain system. Make the drain line from the unit to the air gap above the “open funnel” as short as possible. There should be no horizontal piping between the unit and the air gap above the “open funnel.” The “open funnel” is intended to eliminate any water from entering the steamer because of a blocked drain, and it also prevents any back pressure within the steamer cavity. Any connection that allows the build-up of back pressure in the unit (such as a reduction in pipe size to a line smaller than 3/8", or more than one 90-degree angle in the line prior to the “open funnel” drain discharge point) may cause personal or property damage and will therefore void the warranty. The unit is a pressureless, free-venting steam cooker and will not operate properly unless the drain line is short, at a steep angle, and open! See Figure 6 below.
