Preventative Maintenance Checklist
Operator Maintenance
Users are responsible for the thorough inspection of the
equipment before and after each use. Should any
problems or deficiencies arise, the results must be reported
to the facilities maintenance personnel. The safety of
personnel and patients relies on the proper and routine
maintenance of this equipment.
Daily Checklist
1. Ensure that the correct operation and maintenance
manual is available to all users.
2. Ensure that all personnel using this appliance have
been properly trained in the warmer cabinet operation
and safety instructions.
3. DO NOT overload cabinet. Load contents (blankets
or fluids) into the chamber with a minimum of 1 inch of
space between walls and fan to allow for circulation
(as seen below).

Weekly Checklist
1. Inspect condition of plug and cord. Replace if
damaged.
2. Clean dust from back and side vents.
3. If any of the chamber shelves are unstable when
setting objects on them, check the shelf clips that the
shelves sit upon. Make sure these are not loose. If any
are loose, snap back into place.
4. Check basket shelves (if applicable) and side rail
condition. Do the baskets move smoothly and freely?
5. Check that all control indicators (heat and alarm)
and LED display light up. LED Display panel must show
lighted top and bottom displays. Heat light will stay
on solid while the unit is heating up to its Set Point
Temperature. Once the Set Point temp is reached, the
light will begin to pulsate, and will continue to pulsate
to maintain the Set Point temp.
6. Periodically check the alarm by setting the
temperature ±15° from set point to test the alarm. If
the temperature rises or drops 15° below its set point,
the alarm should buzz and its light goes on. (Note:
90° is the lowest temperature point. To test alarm
from this point, heat the unit up 15° beyond its lowest
temperature, then bring the set point down to test the
alarm.)
Monthly Checklist
1. Check condition of casters or feet. Ensure components
are secure and tightly threaded.
2. Check control panel overlay condition. Are there any
tears or excessive wear on the graphic? Does the
control work properly when buttons are pushed?
3. Is the set temperature comparable to the actual
temperature displayed? Check chamber air
temperature with a quality thermocouple placed 1”
(25mm) from the chamber. Do not allow the sensor to
touch any surface. Monitor for approximately one hour
in an empty chamber.
Semi-Annual Checklist
1. Check the temperature accuracy on a semi-annual
basis by placing an IR Temp probe or thermocouple
on calibrated meter near the fan inlet. In general,
air temperature should be ±1°F for upper chamber
and counter top units and ±3°F for lower chambers
and large single cabinet units. See table column
“Temperature Tolerance” on page 18 for details. If
the cabinet is not within these guidelines, contact MAC
Medical for further assistance.
2. Inspect the Fan blades for buildup of lint and other
debris. Clean as necessary.
nOTe
: MAC Medical
recommends replacing the Fan Motor with Fan blade
(Part # - W0036 (120V)/ W0106 (220V)) every 2 years to
ensure uninterrupted service.
