SECTION I INTRODUCTION
1-1. General
SKYTRON Stainless Blanket and Solution Warming
Cabinets are designed to provide heated storage of
blankets, sterile water and saline solutions used in
the care of patients in surgery, recovery, OB/GYN,
ICU, ER and trauma areas. SKYTRON Model
SS2201-J2(G) offers a compact size with one
warming compartment. Model SS2205-J2(G) offers
a full size cabinet with one warming compartment.
Model SS2207-J2(G) provides upper and lower
compartments.
a. Controls
The controls for each compartment are mounted
in the top section of the warmer and labeled Upper
Chamber and Lower Chamber, with a circuit breaker
providing power to each control.
Each compartment controller:
• Controls on/off of the compartment
• Set point of temperature 90° to 160°
• Temperature display in Fahrenheit
Digital read out provides:
• Chamber temperature
• Temperature set point
• Heating active
• Over heat (alarm)
An audible and visual AL alarm
indicates an overheat condition.
• Loss of power
b. Performance
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 10° of the selected
temperature. From a cold start, each compartment's
loaded contents will be evenly heated to set point
within 8 to 12 hours. In the event of power loss the
warmer will resume normal function once power
is restored.
c. Usage
This device is intended for warming 100% cotton
blankets ONLY and non-ammable solutions in
commercial establishments where all operators/

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.
1-2. Installation / Uncrating
Move the warming cabinet to the location of
installation prior to uncrating.
a. Remove metal banding securing the cabinet
to the pallet.
b. Remove all packing materials covering the
warmer.
c. Remove the warmer from the pallet and position
in desired location.
d. Open the door(s) and remove the shipping
brackets and replace the screws in the body
of the cabinet.
e. Remove the shipping brackets holding the
shelves in the bottom compartment and discard.
f. Install shelf supports as outlined in the Shelf
Adjustment portion of the Operation Section.
