Instructing The Owner; Notice To Owner; Indications Of Proper Operation; Maintenance - York E9FD018 Series Installation Instruction

INSTRUCTING THE OWNER

Assist owner with processing warranty cards. Review User's
Information Manual and provide a copy for the owner guidance
on proper operation and maintenance. Instruct the owner or the
operator how to start, stop and adjust temperature setting. The
owner should also be instructed about the 5 minute off cycle
timer and the defrost operation.
When applicable, instruct the owner that the compressor is
equipped with a crankcase heater to prevent the migration of
refrigerant to the compressor during the "OFF" cycle. The
heater is energized only when the unit is not running. If the main
switch is disconnected for long periods of shut down, do not
attempt to start the unit for 8 hours after the switch has been
connected. This will allow sufficient time for all liquid refrigerant
to be driven out of the compressor.
The installer should also instruct the owner on proper operation
and maintenance of all other system components.
