SECTION 3. OPERATION
3-1. Introduction SKYTRON offers 5 base models of Warming Cabinets to meet each facility’s unique needs: • Model SS2201-M(G) offers a compact size with one warming compartment. See figure 3-1. • Model SS2203-M(G) provides a mid size solution for areas that need more than a countertop version can hold but less than would be needed by a full size unit. • Model SS2205-M(G) offers a full size with one warming compartment. See figure 3-2. • Model SS2207-M(G), a dual chamber solution, provides upper and lower compartments for maintaining different heated goods at different temperature settings. See figure 3-3.
for increased heating efficiency. Doors are made of double panned stainless steel or double paned tempered glass framed with extruded aluminum. Heated air is circulated over the contents by fan(s) in a convection function providing an even heat distribution. Each compartment is designed to hold a quantity of blankets or solutions. Once a set temperature is selected and obtained it will be controlled throughout within +/- 3° F (1.7 °C) of the selected temperature. From a cold start, each compartment's loaded contents will be evenly heated to a setpoint within 8 to 12 hours. In the event of power loss the warmer will resume normal function once power is restored.
• Model SS2209-M(G) offers a unique triple chamber solution for storage of multiple items that need individual temperature setting in one cabinet eliminating the use of multiple units in a given area. See figure 3-4. The Warming Cabinets are designed to provide heated storage of blankets, sterile water and saline solutions used in the care of patients by healthcare facilities. The body of the warming cabinet is double walled stainless steel construction with insulation

WARNING Explosion or Fire Hazard: DO NOT use Warming Cabinet in the presence of flammable anesthetics or solvents. Loading the cabinet with any item that could introduce flammable agents into the cabinet atmosphere can cause a fire or explosion. 1. Make sure the power cord is plugged into a properly grounded 120VAC electrical outlet. 2. Press the control panel switch to the ON position. The display will show the actual chamber temperature. Setpoint temperature range.
CAUTION Burn Hazard: DO NOT raise the setpoint temperature to increase the rate of heating. On double or triple chamber cabinets, do not exceed 30° F (16.7 °C) higher temperature than the chamber above. Example: Upper chamber 110° F (43 °C) lower chamber must not exceed 140° F (60 °C). This could overheat the contents leading to possible patient burns. Temperature settings for fluids vary depending on use or manufacturer. Always refer to AORN guidelines and the fluid manufacturer’s recommendations for proper temperature settings.
WARNING Explosion Hazard: DO NOT exceed 150° F for non-vented closures; (screw caps, crimp seals, plastic pouches, etc.) DO NOT exceed pre-sterile solution manufacturer’s temperature requirements. Single chamber Warming Cabinet models: SS2201, SS2203 and SS2205 setpoint temperature range: • 90° F (32 °C) to 160° F (71 °C)
Double chamber Warming Cabinet model SS2207 setpoint range: • UPPER: 90° F (32 °C) to 160° F (71 °C) • LOWER: 90° F (32 °C) to 160° F (71 °C) Triple chamber Warming Cabinet model SS2209 Setpoint range: • UPPER: 90° F (32 °C) to 160° F (71 °C) • MIDDLE: 90° F (32 °C) to 160° F (71 °C) • LOWER: 90° F (32 °C) to 160° F (71 °C) All loads should be allowed time to stabilize at the Setpoint temperature: Solutions - Approximately 8 to 12 hours Blankets - Approximately 6 to 8 hours Selecting the temperature setpoint.
CAUTION Burn Hazard: The recommended temperature limit for warming solutions is 110° F (43 °C). Solutions warmed above 111°F (44 °C) can cause second degree burns.
