  4. Refrigerant Lines: Connect pre-charged linesets following manufacturer guidelines.
  5. Condensate Drain: Install according to local codes.

WARNING! Unit is heavy; use proper lifting equipment. Installation must be performed by a qualified HVAC technician.

First-Time Setup

After installation, perform initial startup procedure.

  1. Electrical Check: Verify correct voltage and proper grounding.
  2. Refrigerant Charge: Check charge using superheat/subcooling method.
  3. Thermostat Wiring: Connect to compatible thermostat following wiring diagram.
  4. System Test: Power on unit and test cooling operation in stages.
  5. Airflow Verification: Check indoor airflow and adjust blower speed if needed.

CAUTION! Disconnect power before servicing. Follow all local electrical codes.
