CONDENSER FINS ARE VERY SHARP
USE EXTREME CAUTION WHEN CLEANING
Quarterly
: Thoroughly clean the condenser fins on all
air
-
cooled machines. Remove all lint and dust with a
vacuum cleaner or compressed air (Fig. 33) to clean
fins. A dirty condenser greatly reduces refrigeration
capacity and efficiency. When using compressed air,
place a damp cloth on the opposite side of the
condenser to catch the flying dirt or lint.
Annually:
Check the belts for signs of wear or cracking.
Remove panels and clean all parts inside of the machine
including the base, side panels, fan blades, condensers,
etc.
DISCONNECT THE MACHINE FROM ITS POWER
SOURCE(S) BEFORE PERFORMING ANY ROUTINE
MAINTENANCE. PERSONAL INJURY OR DAMAGE
TO THE MACHINE COULD RESULT IF THIS
PRACTICE IS NOT OBSERVED.
Daily:
Inspect the machine for signs of product leaks
past seals and gaskets. If proper assembly does not
stop leaks around gaskets or seals, check for improper
lubrication and worn or damaged parts. Replace parts
as needed.
Periodically:
Inspect the scraper blades (Fig. 32) to
see that they are straight and sharp. If worn, damaged
or warped, the blades will not scrape the cylinder walls
correctly and the freezing capacity will be reduced.
Clean the drip chute assembly with warm water and
detergent solution.
