EQUATOR ® Convective Warmer Service Manual
Chapter 1 Description
1 Description
EQUATOR ® Convective Warmer
The EQUATOR ® Convective Warmer is used to reduce hypothermia and patient
discomfort before, during and after surgical procedures. The system consists of a
high-flow warming device with hose-end temperature control and a single-use
blanket.
The EQUATOR ® Convective Warmer draws ambient-temperature air through a
particulate air filter. The filtered air is warmed to a selected temperature. The
warmed air enters the blanket through the hose and is distributed through
delivery channels to the patient. Perforations on the patient side of the air
delivery channels in the blanket gently disperse warm air over the patient,
thereby maintaining patient temperature.
The warming device has three outlet temperature settings that provide flexibility
in patient treatment: 36°C, 40°C, and 44°C. These three temperature settings are
servo-controlled by thermistors placed at the hose end that connects to the
blanket. A fourth temperature setting delivers ambient-temperature air.
The temperature indicated on the display of the warming device is the
temperature of the air being delivered to the blanket at the end of the hose.
An over-temperature system monitors the air temperature at the end of the hose
that connects to the blanket. A control thermistor adjusts the power applied to the
heater in the warming device to maintain the selected temperature. This enables
the system to maintain the selected temperature under variations in ambient
temperature.
A safety thermistor provides a signal to a separate high temperature comparison
circuit. The safety thermistor activates and alarms if the temperature exceeds the
set point. The safety circuit provides an independent means of shutoff, which
discontinues power to the heater and blower. This prevents patient exposure to
excessive temperatures in a single fault failure of the temperature controller.
Convective Warming Blankets
The blanket consists of two layers of non-woven polypropylene fabric coated with
a layer of polyethylene. The layers are bonded together to form a distribution
network of air delivery channels. The warm air is distributed around the blanket
through the delivery channels and exits the blanket through a specially designed
series of perforations in the patient side of the blanket. The distribution of air is
designed to minimize temperature differences throughout the blanket.

Symptom
Disconnect LED
is immediately on
and stays on, no airflow is detected, and
the temperature reading is
approximately ‘00’.
The temperature reading is between
00°C and 30°C.
Possible Cause/Solution
Check the thermistor cable connections for the hose.
1. Check that the hose air connector is fully inserted to the
interlock switch inside air outlet on the rear of the device.
2. Disconnect the power cord from the electrical outlet and
check physical function of the microswitch with a finger on
the inside top of the air outlet. There should be a distinct
“click” as it operates.
3. Try a second hose if the thermistor cable connection is
suspect.
Note: There is no delay before starting self-test unless the hose end temperature is above the Over
Temp trip point for the newly selected temperature (e.g. Shutting off at 44° and right back ON,
selecting 36°). Under this condition, the device may beep and the display may be irregular until
the device drops below the Over Temp point for the newly selected temperature (e.g., 39°). This
could take up to 10 seconds.

Appendix B Troubleshooting
Thermal Runaway – Device Causes T-Stat to Open
Symptom
Possible Cause/Solution
Motor Stopped
The T-Stat opens if the motor is stopped while a
temperature is selected. This happens because there is no
delivery of heated air to the hose-end sensors.
Note: When this happens, always check the impeller for
heat damage.
Motor Running
The T-Stat opens if the heater is constantly on, or if the
airflow is greatly reduced.
1. If the temperature reading is normal,
• Check for a crushed hose.
• The device may have been used with a restricted air
outlet.
2. If the temperature increases, (look on Control Electric
Assembly )
• If HEAT CONT LED is OFF, then the Mains Electronic
Assembly solid-state relay K2 has shorted.
• If HEAT CONT LED is ON, then the Control Electronic
Assembly heater servo loop has malfunctioned.
Safety Leakage Test
Symptom
High leakage – especially reverse polarity
Possible Cause/Solution
1. Be sure there is no permanent connection between the
motor mounting plate and the rear chassis (EARTH
GND).
2. Check for an earth ground wire that was removed, and
not reinstalled correctly.
