Required Accessories
Operation of the NORM-O-TEMP
®
unit requires the use of the blanket/pad(s) designed to circulate
warm water via a connecting hose with quick-disconnect male and female couplings. NORM-O-
TEMP
®
System Equipment and accessories are listed in Figure 8.
Note: Some reusable blankets/pads come with a permanently attached hose.

Functional Description of the NORM-O-TEMP
®
System
When started up, the NORM-O-TEMP
®
unit heats the water to reach a preset set point
temperature of *42°C/107°F unless an alternate temperature is selected by the health care
provider. The water circulates through the blanket/pad(s) which keeps a patient comfortable.
*42°C = 107.6°F, which will truncate to 107°F on the display.

Heating System
The NORM-O-TEMP
®
heating system consists of an immersion heater and water temperature
control. The temperature ranges are described in Section 2.
The immersion heater is located in the circulating reservoir. The water circulating in the
reservoir flows around the immersion heater and is warmed.
It is important to note that the rate of change in the circulating water temperature is not
directly proportional to the rate of change in the temperature of the patient.

Circulating System
The NORM-O-TEMP
®
6-quart (5.7 liters) capacity dual compartment reservoir is composed of
the circulating reservoir situated under and connected to the replenishing reservoir. When
the operator fills the reservoir with distilled water, the circulating reservoir fills first and holds
approximately 1 ½ quarts (1.4 liters) of water. The remaining 4 ½ quarts (4.2 liters) are held
in the replenishing reservoir. The water moves from the replenishing reservoir to the
circulating reservoir by gravitational pull as needed.
The circulating water flows over the heating element located in the circulating reservoir. The
heated water then flows out the reservoir to the circulating pump, through the pump housing,
over the water temperature sensor, and into the blanket /pad(s). The water circulates
through the blanket /pad(s) and returns to the unit. The water then passes through the water
flow indicator and returns to the circulating reservoir to be reheated and then recycled.
An internal by-pass inside the NORM-O-TEMP
®
by-passes the Hansen fittings and the flow
indicator for water circulation during preconditioning of the water.
The circulating water system contains a flow indicator. The operator should check the flow
indicator for proper flow when operation is first begun with a blanket or bypass hose attached.
In addition, the circulating reservoir contains a low water level sensor which shuts down the
unit and sounds an alarm if the water level drops below 1 ½ quarts (1.4 liters). The unit
becomes operational after the water level is restored to normal.
