1.2. Getting Started
Plug the mains cable into a conventional, properly earthed 240 Volt 10 Amp mains power
socket-outlet and switch it on. The green Standby indicator (B) will illuminate and the
CWS4000 will beep when power is connected.
Ensure that air is not prevented from entering the inlet slots at the sides by blankets or other
objects.
Remove the CE Marked warming blanket from its packaging. Unfold the warming blanket and
place it over the patient. Refer to Section 2 below for more detailed instructions on
warming blankets. Connect the air delivery hose to the warming blanket by pushing the plastic
fitting into the air inlet port and securing it firmly. Please note that when using the CWS4000
warming unit with a Bair Hugger™ blanket a delivery hose nozzle adaptor is required (Part
Number CWS203); please contact your Care Essentials representative or agent. Refer to
Section 8 below for commingling information relating to the use of Cocoon warming unit and/or
blankets with other manufacturer’s warming units and blankets.
1.3. Unit Operation Procedure
Select the desired temperature on the control panel by pressing the ambient temperature
output button (C) or one of the output temperature selection buttons (E). The appropriate
green or yellow light (D or F) will indicate the selected temperature setting. Another temperature
may be selected at any time. When using the 34
o
C, 37
o
C, 40
o
C, 43
o
C, or 46
o
C temperature
settings, place your hand under the warming blanket to confirm that the CWS4000 is supplying
warm air. Placement of a blanket, sheet or drape over the inflated warming blanket may be
undertaken to maximize the efficiency and minimize the heat loss from the system. When using
additional covers it is important to ensure air flow through the convective warming blanket is not
disrupted.
The internal timer will automatically decrease the temperature setting from 46
o
C to 43
o
C after 10
minutes. This timer can be reset by re-selecting the 46
o
C temperature setting.
Switch the unit off by pressing the standby button (A). The green standby indicator (B) will
illuminate when the unit is off.
