  • Page 9 Installation (CONT’D) Step 5 Prepare Unit Line Set Connections Rotate refrigerant line stubs set gently through 90° (if mounting on an outside wall). For other line set configurations align the stubs as required. Condensate Hose Hose connection is sized to accept a 5/8'' OD or 1/2'' ID clear plastic hose to then extend to building drain. Connect it to the gray condensate line coming from the indoor unit.

    Installation (CONT’D). Step 6 Install unit on mounting bracket. Feed the line set stubs/condensate hose/wiring connections through the 3'' hole. Installation can be made easier by lifting the indoor unit and inserting a cushioning material (spacer) between indoor unit and the wall. Hook the top of the indoor unit to the top of the bracket (2 or 3 places) and once hooked, gently let it swing down and then push the lower portion of the indoor unit against the bracket until it snaps into the bracket.
  • Page 11 Installation (CONT’D). Step 8 Install drain joint Heat pump units require a drain joint. Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. Note that there are two different types of drain joints depending on the type of outdoor unit. ●...

  • Page 22: The Importance Of Deep Vacuum

    THE IMPORTANCE OF DEEP VACUUM The purpose of a vacuum pump is to remove moisture and air from an A/C-R system. Modern systems are built tighter and charges are more critical. That means these systems have a greater sensitivity to moisture and other contaminants, making thorough evacuation more important than ever before.
