SECTION V: INSTRUCTING THE OWNER

Assist owner with processing warranty cards and/or online registration.
Review Owners Guide and provide a copy to the owner and guidance
on proper operation and maintenance. Instruct the owner or the opera-
tor how to start, stop and adjust temperature setting.

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 peri-
ods of shut down, do not attempt to start the unit until 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.
