11. Full function check of Main Unit
GENERAL
•
This procedure and corresponding protocol are to be used during a full function check of the
KANMED WarmCloud OT600 system.
•
If nothing else is stated, the default setting of 37ºC and 30 mb. are presumed to be used during
operation of the system.
•
The main PCB has two LED indicators that are useful to observe. The red LED indicates that the
computer has activated the heater elements. During the initial heating phase, it should be lit 80-
100% of the time, and when the system is in thermal balance (after more than 10 minutes of
operation), the indicator should be flashing with approximately 2 Hz. The green LED indicates that
the computer has activated the compressor.
PREPARATION
a) Remove the casing of the main unit, and perform an internal ocular inspection of the chassis.
b) Refit the air hoses and the hand controller.
c) Connect the main unit to an OT600-220 standard mattress.
d) The pressure is measured with an accurate manometer (DIGITRON P200M or similar). The
temperature is measured with a FLUKE 52 II (or similar thermometer). Power consumption with an
ampere meter.
e) Electric safety test are performed according to standard for medical technical equipment, IEC 601.1
Class II type B.
