Step 6
Install unit on Mounting Bracket
Feed the line set stubs/condensate hose/wiring connections through
the hole in the wall, then locate the unit key slots onto the tabs on
the mounting bracket. Bottom of the unit then latches onto the
mounting bracket. Indoor unit is now installed, it should be plumb,
level and flush with the wall. If it is not check that the line set stubs
are completely through the wall penetration, and the wall is plumb

Do not install the Outdoor unit in a location exposed to high winds (field fabricated and installed wind baffle
may be required).
Ensure location does not impede access around unit and pose a disturbance to neighboring areas
Step 8
Refrigerant Line Set Piping
Interconnecting line set between the Outdoor unit and the Indoor unit, MUST have both refrigerant lines
insulated as condensing device is located in the Outdoor unit
Gently bend the line set stubs from the Indoor unit to the desired position
Using 2 x 10"/12" Crescent wrenches remove the flare nuts from the Indoor unit line stubs.
Indoor unit has a holding charge of a dry gas, check for release of this to ensure that no leaks are present
Use a small amount of vacuum pump oil on the male flare threads to ease installation. Connect the line set to
the stubs. Using the 2 wrenches, 1 on the male & 1 on the female tighten the flare nuts
DO NOT INSTALL A LIQUID LINE SIGHT GLASS OR FILTER DRIER IN THE SYSTEM
Run the line set to the Outdoor unit, avoid tight bends and kinking the lines. Quietside does not recommend
brazing line sets together or to the unit connections
If line set length is in excess of that required, cut line set and re-flare or coil excess vertically to facilitate oil
return to the compressor
