Preventive Maintenance Plan
The TEMP 2
temperature controller should be verified every five (5) years. Medical Solutions,
Inc. requires the use of the following items to accurately measure the bag temperature for
verification.
Fluke 51II Digital Thermometer
6” Long .093” Diameter Type T Needle Thermocouple
(with the Thermocouple calibrated to the Thermometer)
With the outer wrap still on a three liter IV fluid bag, pierce the bag through the needle injection
port on the bag with an 18ga needle to make it easier to insert the Thermocouple. Insert the
Thermocouple through the pierced needle injection port. Place the fluid bag onto the center of
the bottom shelf. Load the top shelf with an additional three liter IV fluid bag. Feed the
Thermocouple wire attached to the Fluke Thermometer out of the cabinet positioning the probe
in the center of the bag. Close the door.
Turn the power on to the TEMP 2
. Adjust the temperature controller set point temperature to
104
F for both shelves. Allow the unit to operate for a minimum of 6 hours before verifying the
temperatures. After the allotted time, compare the temperature reading on the controller to the
temperature reading on the Fluke Thermometer, the two temperatures should be within two
degrees Fahrenheit of each other. If the two temperature readings are within two degrees
Fahrenheit of each other, the temperature controller has been verified. If they are not, please
contact Medical Solutions, Inc. at 800-435-7600.
Repeat the calibration process for the top shelf of the TEMP 2
.
If a Fluke Digital Thermometer is not available an alternative method to verify the controller is
to use a glass laboratory thermometer. Place 1 three liter IV bag onto the center of each of the
shelves. Turn the power on and adjust the temperature controller set point temperature to 104
F
for both shelves. Allow the unit to operate for a minimum of 6 hours before verifying the
temperatures. Remove the bag and place the end of the glass thermometer on the top and in the
middle of the bag. Fold the bag over the thermometer and hold for approximately two minutes
or until the mercury stops moving. If the reading on the thermometer is between 100.4
F and
105.8
F the temperature controller has been verified. If they are not, please contact Medical
Solutions, Inc. at 800-435-7600.
Repeat the calibration process for the other shelf of the TEMP 2
.
