h. Clean all exterior and interior surfaces of the warming cabinet as needed with a damp towel and a mild non-abrasive detergent. Rub surfaces in a back and forth motion in the direction of the grain, do not wipe in a circular motion or perpendicular to the grain. i. Plug the power cord into a properly grounded 120V electrical outlet. 1-3. Service / Principles of Operation This equipment contains no user serviceable parts. To avoid injury, refer all repairs to SKYTRON trained service personnel. Model SS2201-J2(G) is a single compartment 1/3 size, SS2205-J2(G) is a single compartment full size, and model SS2207-J2(G) is a dual compartment full size warmer. Each compartment has independently controlled temperature regulation by a thermostatic control unit and independent thermal protection cut off. Each warming compartment is designed to circulate air from the top of the chamber over a heating source, which cycles on and off by means of a sensor to maintain set temperature, and back out at the bottom of the chamber. This process produces a convection type of heating system. Dual compartment warmers have an air barrier between the upper and lower compartments restricting heat migration to the upper chamber and affecting the temperature setting.

SHELF SUPPORT (4 per shelf) FRONT

g. Make sure the cabinet is leveled properly to the floor or counter top by adjusting the leveling feet at the bottom of the cabinet. To promote self closing door swing, the front door hinge corner leveling foot should be slightly higher than the others.

Bottles should be loaded to allow for a minimum of one half inch from the top of the compartment and spacing around the back and sides one quarter inch and not protrude past the front edge of the fluid tray in the compartment for evenly distributed heating. For efficiency purposes bagged solutions should be placed on shelves, stacking of fluid bags increases the heating time required to achieve set temperature. Blankets must be folded and stacked to allow a two to three inch open space between the top of the compartment or shelf, on each side and rear of the stacked blankets, nor protrude past the front edge of the shelf. Following the above guidelines improves the efficiency of heating the contents thoroughly. Rotate warmed contents on a first in first out basis failure to do so may present cold or discolored contents. Temperature settings for fluids vary depending on use or manufacturer. Always refer to AORN guidelines and manufacturer’s recommendations for proper temperature settings. Flammable agents in the warming cabinet can cause an explosion or fire. Do not load the warming cabinet with any item that could introduce flammable agents into the cabinet atmosphere. In case of power failure the unit will resume normal operation when power is restored.
