MAINTENANCE AND CARE FOR THE

EQUIPMENT OWNER

Before proceeding with those things you might want to maintain yourself, please carefully consider the following:

!WARNING

ELECTRICAL SHOCK AND CUT HAZARD

Failure to follow this warning could result in personal in- jury, death or property damage.

1.TURN OFF ELECTRICAL POWER TO YOUR UNIT BEFORE SERVICING OR PERFORMING MAINTE- NANCE.

2.When removing access panels or performing mainte- nance functions inside your unit, be aware of sharp sheet metal parts and screws. Although special care is taken to reduce sharp edges to a minimum, be extremely careful when handling parts or reaching into the unit.

AIR FILTERS— Air filter(s) should be checked at least every 3 or 4 weeks and changed or cleaned whenever it becomes dirty. Dirty filters produce excessive stress on the blower motor and can cause the motor to overheat and shut down. Table 1 indicates the correct filter size for your unit. Refer to Fig 2 to access the filter(s).

To replace or inspect filter(s) (or accessory filter rack when supplied):

1. Remove the filter access panel using a 5/16-in. nut driver.
