FAQs

What do the safety signal words DANGER, WARNING, CAUTION, and NOTE mean in this manual?

DANGER indicates immediate hazards that can cause severe personal injury or death. WARNING indicates hazards or unsafe practices that could cause severe injury or death. CAUTION indicates hazards or unsafe practices that may result in minor injury or product/property damage. NOTE highlights suggestions that enhance installation, reliability, or operation.

How should R-410A systems be serviced and what equipment considerations are required?

The manual states R-410A operates at 50% to 70% higher pressures than R-22, so servicing equipment and replacement components must be designed for R-410A. Recovery cylinder service pressure ratings must meet 400 psig requirements, and the system should be charged with liquid refrigerant.

How do you identify the outdoor unit model number for single-phase units?

The outdoor unit model number identification guide maps digit positions to components of the part number, using codes for mainline branding, type (air conditioner or heat pump), SEER value, nominal capacity, features, voltage, sales code, engineering revision, and extra digits.
