Task
Clean the ice scoop using a neutral cleaner. Rinse thoroughly after
cleaning.
Inspect. Wash with warm water and neutral cleaner if dirty.
Check for proper pressure and change if necessary.
Wipe down with a clean, soft cloth. Use a damp cloth containing a
neutral cleaner to wipe off oil or dirt build up. Clean any chlorine
staining (rust colored spots) using a non-abrasive cleanser.
Wipe down with a clean cloth and warm water.
Clean and sanitize per the cleaning and sanitizing instructions
provided in this manual.
Wipe down with a clean cloth and warm water. Slowly pour one cup of
sanitizing solution (prepare as outlined in the sanitizing instructions
in this manual) into the evaporator condensate drain pan and then
slowly pour one cup into the gear motor drain pan. Be careful not to
overflow the pans. Repeat with a cup of clean water to rinse.
Check to make sure they are clear.
Inspect for leakage around seal bolts. Tighten (see torque values
below) or replace as necessary. Seal bolts must be replaced once
removed because seal material is one-time use only. If new seal bolts
do not have preapplied threadlocker, apply Loctite 243 or equivalent
threadlocker to seal bolt threads.
• Torque: 11.1 ft-lb/15 N·m
Tighten 2 times. Allow at least 5 sec. in between each tightening.

Check for wear using .02" round stock or pin gauge. Replace both
upper bearing and lower bearing if wear exceeds factory
recommendations. See the Service Manual for details.
Inspect. Replace both upper bearing and lower bearing if wear
