Choose an area where the wall is plumb and determine how to best run the unit interconnects. 5” from wall 5” from wall Optimum 8 ft plus from floor ALL VIEWED FROM FRONT SIDE For model: WM6H424ZMI For models: WM9H424ZMI, WM12H424ZMI 950-0285 - 6 - April 18, 2022... - Page 8 For models: WM18H424ZMI, WM24H424ZMI Ensure no obstacles to airflow are directly in front of the unit, for a minimum of 12 ft for 9,000 / 12,000 Btu/h units and 16 ft. for 18,000 / 24,000 Btu/h units. Do not install the indoor unit in areas exposed to high humidity (RH of 80% plus), direct sunlight, direct heat from stoves or other devices.
- 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.

(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) ● If the drain joint comes with a rubber seal (see Fig. A), do the following: 1. Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit. 2. Insert the drain joint into the hole in the base pan of the unit. 3.

Page 23: 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. -
