Preventive Maintenance Plan
The TEMP 3
temperature controller should be verified at least once every five years. 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 1000ml solution 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 bag into the TEMP 3
through the lower door of the cabinet. Feed the Thermocouple wire out of the cabinet to the
Fluke Thermometer and position the probe in the center of the bag. Close the lower door. Add
five additional bags to the cabinet from the top loading door.
Turn the power to the TEMP 3
on. Adjust the temperature controller set-point temperature to
40
C. Allow the unit to operate for a minimum of 1 hour before verifying the temperatures.
After the allotted time, compare the temperature on the controller to the temperature reading on
the Fluke Thermometer. The two temperatures should be within one degree Celsius of each
other. If the two temperature readings are within one degree Celsius of each other the
temperature controller has been verified. If they are not, please contact Medical Solutions, Inc.
at 800-435-7600.
If a Fluke Digital Thermometer is not available a glass laboratory thermometer may be used as
an alternative. Load the unit with (6) 1000ml bags and turn the power on. Adjust the
temperature controller set-point temperature to 40
C. Allow the unit to operate for a minimum
of 1 hour before verifying the temperatures. Remove the bottom bag and place the end of the
glass thermometer on top of and in the middle of the bag. Fold the bag over the thermometer and
hold for approximately two minutes or until the thermometer stops moving. If the reading on the
thermometer is between 38
C and 41
C the temperature controller has been verified. If it is not,
please contact Medical Solutions, Inc., at 800-435-7600.
