1) Wash all bowl components regularly.
2) Wash impeller and bearing sleeve individually and check for
wear.
a) Check for wear on bearing sleeve (flange should be
1.77mm thick - thickness of penny or quarter). (Figure F)
b) Check for wear on impeller (inner white center section
should be flush with colored part of impeller). (Figure E)
c) If bearing sleeve or impeller do not spin freely or are worn
- replace them. (Figure I)
d) Worn parts can cause personal injury, impair cooling and
can damage machine. (Figure G & H)
3) Check valve o-rings and bowl gaskets for wear or damage -
replace every 6 months or as needed.
4) Every 6 months or more often if needed: unplug unit, remove
panels, clean condenser and interior. (Remove dust and lint
from fins with a soft brush and vacuum.)
