MAINTENANCE AND TROUBLESHOOTING PROCEDURE
MAINTENANCE
Service should be performed by a
qualied service agency and an annual
system check is recommended. EMI units
are designed and constructed for reliability
and long life with minimal maintenance. To
insure peak operating efciency:
1. Clean air lter on a monthly basis or
when it is visibly dirty*:
a) The lter is accessed by removing
the front air intake access grille:
• Lift and remove grille
2. To clean the lter pull open the 2 clips
at the base of the lter and carefully pull
the lter out. Place the lter on a at
surface.
a) To vacuum: Use a brush attachment
and vacuum all visible dirt.
b) Or use a garden hose: Follow steps
1 and 2 then hose lter off. Let lter
dry before replacing.
*Allowing dust to collect on the lter will
result in reduction of air ow and cause
the unit to lose efciency. This condition
will cause the unit to malfunction.
Turn the POWER OFF to the unit be-
fore servicing or cleaning.
