Lubrication
DISCONNECT THE POWER SUPPLY TO
THE UNIT BEFORE SERVICING TO
PREVENT A SHOCK HAZARD OR
POSSIBLE INJURY FROM MOVING PARTS.
DANGER
The blower drive motor on some units may include
oiling cups at the top of the motor. There is no
requirement to oil the journals under normal
operating conditions. However, if lubrication to the
unit is desired, use only SAE 20 non-detergent type
oil. DO NOT OVER OIL, three to four drops in
each oil hole once a year is sufficient.
