Annual Maintenance
1. Check all refrigerant lines for leaks or fatigue. Make
certain that no exposed copper tubing is in contact with
any other metal surface. If there is contact, install an
insulating material between the two metal components.
2. With the breaker at the main panel “OFF”, inspect the
system’s wiring. Look for a tight fit of all connections
and make certain that the wire restraining devices are
tight. Inspect all wires and cords, paying particular
attention to nicks or age cracks in the insulation.
3. Visually inspect the outer panel and components of the
cabinet. Check screws and bolts to make certain that
they are tight. Also, make sure that the bolts that
secure the base frame to the deck are tight.
Three Year Frequency
1. Replace the drawer gaskets. To accomplish this, it is
first necessary to remove all products from the
refrigerated compartment to avoid spoilage. Open the
drawers and remove the old gasket. The gaskets snap
in and out of a channel on the back side of the door.
Clean the track thoroughly. Replace the old gasket
with the new one by snapping it into place.
2. Inspect all motors and shafts i for both noise and wear.
If they show age, replace them.
3. With the main power off, remove the condensing unit
from its compartment and inspect all wiring. Also,
remove the cover from the controls and check them to
make certain that they are operational and do not show
signs of wear.
4. Inspect the operation of the drawer slide assembly.
Make certain that the moving parts do not show any
signs of wear. Make sure that all screws are tight.
5. To recalibrate the thermometer, remove it from the
cabinet. Using a small, flat screwdriver, remove the
lens. Prepare an ice water bath and immerse the
thermometer bulb at least two inches into the ice bath.
WIthin 30 seconds the indicator dial should read 32
degrees Fahrenheit. If it does not, it needs to be
recalibrated. Do this by placing your index finger on
the opposite side of the needle that needs to move.
Then, using a flat screwdriver, turn the screw at the
center of the dial 1/4 of a turn in the direction you want
to move the dial. Repeat the procedure until the
needle is on 32 degrees. See Figure 4.1.
