Water Specification; Drain Line - Southbend R2 Operator's Manual

WATER SPECIFICATION:
To meet warranty requirements,
supply water must meet the following specification:
Pressure:
30 to 60 psi
Total
Dissolved Solids (TDS): 60 PPM
Hardness: 2 Grains or 35 PPM
pH Factor:
7.0 to 7.5
DRAIN LINE:
The drain line connection size from the unit is 1" NPT (32 mm). 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 elimi-
nate any water from entering the steamer because of a blocked drain and it also prevents any back pressure within the
steamer cavity. The unit must be free-venting to the atmosphere. Any connection that allows the build-up of back pres-
sure in the unit such as a reduction in pipe size to a line smaller than 1" or a 90 degree angle in the line prior to the
"open funnel" drain discharge point may cause personal or property damage and therefore will void the warranty. This 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 3.

A WARNING
BURN HAZARD
It is imperative that the drain connection be installed per instructions and kept clean (open) to assure
free venting to atmosphere. A clogged drain will cause pressure to build up inside the steamer cavity
and can endanger the operator when opening the door. It will also cause excessive leakage of
steam from the door.
NOTICE
Floor drain must be located outside the confines of the equipment base or damage to equipment may
occur.
Do not locate unit adjacent to any high heat or grease producing piece of equipment, such as a range top, griddle,
fryer, etc., that could allow radiant heat to raise the exterior temperature of the steam body above 130°F (54°C).
DO NOT MOUNT ABOVE OTHER COOKING EQUIPMENT.
