5 THE EQUATOR™ CONVECTIVE WARMER (EQ-5000)
5.1 EQUATOR™ Blankets
The blanket consists of two layers of non-woven polypropylene fabric bonded to 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.
Level 1®Convective Warming Blankets (SW-2001, SW-2002, SW-2003 and SW-2004) are compatible with
the Bair Hugger 505.
5.1.1 Warming Blanket External Features
The Level 1 convective warming blanket dimensions and configurations will vary, depending on the
specific application. Refer to Table 3 and Figure 5 for blanket information.
5.1.2 Blanket Retainer
The Level 1 convective warming blanket retainer ring is built into the hose end to secure blanket
connection. Effective transfer of warm air from the hose to the blanket is assured through blanket
retention.
5.1.3 Air Delivery Channels
Warmed air enters the blanket through the hose and travels to an air supply manifold. The air manifold
distributes the warmed air to delivery channels in a pattern designed to promote heat transfer to the
patient. Perforations on the patient side of the air delivery channel gently disperse warm air over the
patient thereby maintaining patient temperature.
5.2 Convective Warmer
The EQ-5000 is used to reduce hypothermia and patient discomfort before, during and after surgical
procedures. The system consists of a high flow warming unit with hose end temperature control and a
single use blanket.
The EQ-5000 draws ambient temperature air through a particulate air filter. The filtered air is warmed to
a selected temperature and delivered through a hose to a blanket.
The EQ-5000 has three outlet temperature settings, which provide flexibility in patient treatment. A
fourth temperature setting delivers ambient temperature air to facilitate patient cooling. These set
temperatures are servo-controlled by thermistors placed at the hose end.
An over temperature system monitors the air temperature at the end of the hose where it connects to
the blanket. A control thermistor adjusts the power applied to the heater in the warming unit 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 reaches 3°C above 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.

10 SERVICE
All service must be performed by Level 1 or a Level 1 authorized representative. Service by any other
person or organization voids the warranty and transfers liability for malfunctions of the device to the
servicing organization.
Warranty Service
Units received for repair, which have not been obviously abused or impact damaged and are still under
warranty will be promptly repaired and returned at no charge. See the Limited Warranty section of this
manual. A no-charge purchase order is requested for tracking.
Non-Warranty Work
Units received which have suffered obvious abuse or impact damage and units no longer under warranty
will be promptly inspected and a verbal estimate of repair cost will be given to you. A purchase order will
be required from the hospital consistent with the verbal estimate. A written estimate will be provided
upon request.
Before returning your EQ-5000 for service, contact Level 1 for Returned Goods Authorization.
NOTE: The EQ-5000 must be cleaned and disinfected for repair shipment or it will be immediately
returned as received.
