Sterilizing Chamber Specifications
The sterilizing cylinder is constructed from 3/16" (4.8mm) thick welded aluminum with a polished stainless steel exterior. Interior dimensions measure 16" (406mm) in diameter and 26" (660mm) long with a cubic content of 5,220 cubic inches (85 liters). Door opening is 13-1/2" (343mm) wide and 11" (279mm) high.
Pan Capacity
- (3) 12" x 20" x 2-1/2" (305mm x 508mm x 64mm) or
- (2) 12" x 20" x 4" (305mm x 508mm x 102mm) or
- (1) 12" x 20" x 6" (305mm x 508mm x 152mm)
Door Design
The sterilizer door is a self-sealing type which cannot be opened until steam pressure is completely exhausted. Constructed from 12 gauge stainless steel, the door is removable for cleaning without tools. The one-piece molded door gasket is replaceable without tools or cement.
Automatic Operation
The sterilizing cycle is fully automatic and time-controlled with a built-in temperature control providing 250°F (121°C). Model STM-EL features an adjustable temperature control that can be set anywhere in the 230°-250°F (110°-121°C) range. All operating controls are located at the top, front of the sterilizer. Pressure is automatically and quickly exhausted and power supply shut off at termination of cycle. Slow exhaust may be selected for sterilizing liquids.

Unit must be grounded. Main supply voltage fluctuations are not to exceed ± 10% nominal supply voltage.
Service Connections
- Drain - 1/2" (13mm) N.P.T. or 3/8" (10mm) OD copper (an air break must be provided if a unit drain line is run)
- Steam Exhaust Connection - 5/8" (16mm) (vent exhaust to atmosphere)
- Electrical Connection - per electrical specifications
Installation Requirements
Clearance from combustible and non-combustible construction should be a minimum of 4" in the back and 2" on the sides. Heat of Rejection (Heat Loss Into the Room) 6,000 BTU'S. Customer provided drain catch pan approximately 4-6 quarts (3.8-5.7 liters) required.
Exhaust Line Requirements
Exhaust line must be vented to the outside to eliminate the exhaust steam and the accompanying noise from entering the room. Use 1/2" (13mm) copper tubing or suitable alternate. The overall height and length of the line should not rise more than 4' (1.2 meters) above the unit and exceed 15' (4.5 meters) with a minimum of bends. The line should slope downward after leaving the sterilizer in order to ensure condensate drainage. Failure to comply with this outline will affect the sterilization process.
Water Supply Requirements
Good quality water feed is the responsibility of the owner. Water quality must be within the following general guidelines:
| TDS: |
40-125 ppm |
| Hardness: |
35-100 ppm |
| Silica: |
<13 ppm |
| Chlorides: |
<25 ppm |
| Chloramine: |
<0.2 ppm |
| Chlorine: |
<0.2 ppm |
| pH: |
7.0 - 8.5 |
The best defense against poor water quality is a water treatment system designed to meet your water quality conditions. Appliance to be installed with backflow protection according to federal, state or local codes.
