E LECTRIC C OUNTER C ONVECTION S TEAMER INSTALLATION INSTALLATION INSTRUCTIONS GENERAL The SX-3 and SX-5 steamers are single compartment electric pressureless steam cookers with an internal electric steam generator that maintains water temperature at approximately 205 Deg F. SX-3 is rated 7.5 kW as standard; 10 kW is optional. SX-5 is rated 15 kW as standard; 12 kW is optional. At high altitude locations a lower temperature is required to achieve atmospheric steaming.
E LECTRIC C OUNTER C ONVECTION S TEAMER INSTALLATION LEVELING Using a spirit level or pan of water in the bottom of the steamer, adjust the leveling feet or the feet on the adjustable legs to level the steamer front-to-back and side-to-side. After the drain is connected, check for level by pouring water onto the floor of the compartment. All water should drain through the opening at the back of the compartment cavity.

INSTALLATION E LECTRIC C OUNTER C ONVECTION S TEAMER PLUMBING CONNECTIONS WARNING Plumbing connections must comply with applicable sanitary, safety and plumbing codes. The water supply inlets are provided with 3/8” (10 mm) compression fittings for 3/8” O.D. copper tubing. The water supply line pressure should be 25 - 50 psi (170 - 345 kPa) for each line. The water supply to the generator tank is separate from the water supply to the cooling system where steam is condensed before entering the drain line.
E LECTRIC C OUNTER C ONVECTION S TEAMER INSTALLATION DRAIN CONNECTIONS (FIGURE 2) The drain connection (Fig. 2) must be 1” IPS down, preferably with one elbow only, maximum length of 2 feet horizontal before open air gap and piped to an open air gap type drain. Drain pipe should be copper. DO NOT use PVC pipe - PVC pipe may lose its rigidity or glue may fail. Figure 2 CAUTION In order to avoid any back pressure in the steamer, do not connect solidly to any drain connection.
E LECTRIC C OUNTER C ONVECTION S TEAMER INSTALLATION WATER QUALITY The water supply connected to this steamer should contain no more than 2.0 grains of hardness per gallon with pH from 6.8 to 7.3. This degree of hardness and pH can easily be obtained with the use of a properly maintained water softener. Water supplies vary from one location to another. A local water treatment specialist should be consulted before installing any steam generating equipment.
