IMPORTANT

Sprinklers and soaker hoses should not be installed

where they could cause prolonged exposure to the

outdoor unit by treated water. Prolonged exposure

of the unit to treated water (i.e., sprinkler systems,

soakers, waste water, etc.) will corrode the surface

steel and aluminum parts

performance and longevity of the unit.

6. Outdoor Unit Make sure no obstructions restrict

airflow to the outdoor unit. Leaves, trash or shrubs

crowding the unit cause the outdoor unit to work harder

and use more energy. Keep shrubbery trimmed away

from the unit and periodically check for debris which

collects around the unit. When removing debris from

around the unit, be aware of metal edges on parts and

screws. Although special care has been taken to keep

exposed edges to a minimum, physical contact with

metal edges and corners while applying excessive

force or rapid motion can result in personal injury.

Cleaning of the outdoor unit's coil should be performed

by a trained service technician. Contact your dealer

and set up a schedule (preferably twice a year, but at

least once a year) to inspect and service your air

conditioning or heat pump system.

THERMOSTAT OPERATION

procedures. Refer to the user's information manual

provided with your thermostat for specific operation

details.

Temperature Setting Levers

the desired temperature setpoints for both heating and

cooling. Avoid frequent temperature adjustment;

turning the unit off then back on before pressures

can equalize will put unusual stress on the unit's

compressor.
