For your convenience, on Model 3000, 3100 and 3500 the proper bed-to-heater spacing is
indicated by a label located on the right aluminum upright (as viewed from the front).
Line Voltage Compensation:
Input line voltage is monitored and the heater drive is adjusted to compensate for
variations in the line voltage. This ensures a stable heater output despite input line
voltage fluctuations.
Circuit Breaker:
Rated Current: 7.5 A.
Trip Point: 9.45 A Minimum.
Type: Manual Resetting.
Model: Airpax Snapak.
Isolation Voltage:
2500 Vrms 60 Hz from the patient probe to the ac phase and neutral lines for one minute.
WARNING:
w
The patient probe is not isolated from earth ground. Any additional equip-
ment used with the Ohmeda Infant Warmer System must comply with UL
544, CSA 22.2, IEC 601, and VDE 750.
Leakage Current:
With ground wire open or connected and measured at an exposed metal surface, less
than 100 microamperes on 100 V and 120 V units (200 microamperes on 220 V, 230 V
and 240 V units).
Ground Resistance:
Less than 0.2 ohms as measured from the power cord plug
