Warning about the intended use of this information and potential risks.
Benefits of installing matched indoor and outdoor systems for efficiency and reliability.
Verify electrical power availability matches the unit's nameplate.
Procedure for removing basepan tabs by cutting.
Unit must be set on a level pad, at least as large as the base pan.
Maintain minimum 12" clearance from walls/shrubbery for adequate airflow.
Top discharge area must be unobstructed for at least five (5) feet above the unit.
Ensure roof supports unit weight and use isolation for vibration.
Maximum length of refrigerant lines from outdoor to indoor unit should not exceed sixty (60) feet.
Limits for refrigerant line lift (suction and liquid) based on unit orientation.
Caution to ensure all joints are brazed, not soldered, when reusing lines.
Route tubing, make required bends, and secure lines to prevent vibration noise.
Avoid direct contact between uninsulated liquid and gas lines.
Take precautions to avoid heat damage to valve cores and basepan during brazing.
Use dry nitrogen purge during brazing for proper connections.
Description of factory-shipped service valves and pressure tap port function.
Warning about extreme caution when opening service valves.
Pressurize lines with dry nitrogen and use soap bubbles to check for leaks.
Evacuate refrigerant lines and indoor coil before opening service valves.
Evacuate the system until the micron gauge reads no higher than 350 microns.
