BEST PRACTICES

Unit Placement

  • ✔️ Follow clearance guidelines on indoor & outdoor units for proper airflow & servicing
  • ✔️ Include space for drainage so condensate flows out of unit
  • ✔️ Anchor both units properly to prevent vibration or malfunction
  • ✔️ Be sure condensate drain tubing is pitched downward for proper drainage

Piping

  • ✔️ Use only correct line set size as determined by indoor unit
  • ✔️ Use only copper refrigerant piping
  • ✔️ Insulate both refrigerant lines from each other
  • ✔️ For flare connections, use a 45° flaring tool such as Yellow Jacket Deluxe
  • ✔️ Use a pipe length that does not exceed the maximum or go below the minimum length
  • ✔️ Do not make vertical loops in the piping; support runs from sagging or bending

Wiring

  • ✔️ Use only 14/4 STRANDED wire
  • Never use wire nuts or wire splices
  • ✔️ L1 & L2 are polarity sensitive
  • ✔️ Use non-insulated spade connectors on all terminal connections
  • ✔️ Use only a dedicated electrical circuit
  • ✔️ Always GROUND indoor & outdoor unit
  • ✔️ Surge protector HIGHLY recommended (I.E. Intermatic AG3000)

Charging

  • ✔️ Test refrigerant lines for leaks by pressurizing with nitrogen to 500 P.S.I.
  • ✔️ While under pressure, use a leak detection solution to test for all leaks at all flare connections
  • ✔️ Use only approved evacuation hose & vacuum pump oil for proper evacuation and leak testing: Evacuate to less than 500 microns and hold for 30 minutes
  • ✔️ If refrigerant is added, use electronic scale and weigh in precise amount
  • ✔️ Open service valves prior to energizing unit
