WARNING: Disconnect power cord before
servicing.
Note: Reconnect all grounding devices.
All parts of this appliance capable of conducting
electrical current are grounded. If grounding wires,
screws, straps, clips, nuts, or washers used to
complete a path to ground are removed for
service, they must be returned to their original
positions and properly fastened.
Caution: To avoid personal injury when servicing
the condensing unit, stand on a ladder which will
give enough support to allow removal of the top
panel and safely allow access to service the unit.
