Start-up procedure
Refer to outdoor unit Installation Instructions for system start-up
instructions and refrigerant charging method details.
CARE AND MAINTENANCE
The system should be regularly inspected by a qualified service
technician. Consult the servicing dealer for recommended frequency.
Between visits, the only consumer service recommended or required is
air filter maintenance and condensate drain operation.
AIR FILTER
Inspect air filters at least monthly and replace or clean as required.
Disposable type filters should be replaced. Reusable type filters may be
cleaned by soaking in mild detergent and rinsing with cold water. Install
filters with the arrows on the side pointing in the direction of air flow.

CAUTION

PRODUCT DAMAGE HAZARD
Failure to follow this caution may result in poor unit performance
and/or product damage.
Never operate unit without a filter. Factory authorized filter kits may be
used when locating the filter inside the unit. For those applications
where access to an internal filter is impractical, a field-supplied filter
must be installed in the return air duct system.
