Step 3
Drill Hole for Line Set etc
Remove mounting bracket from the rear of the Indoor unit, use a Phillips head screwdriver to remove the unit pipe strap, and if
unit is a heat pump the defrost sensor also must be undone from its retainer. If mounting the unit on an outside wall measure
from the edges of the unit to the center of the line set stub 90° bend to locate the center of the
wall penetration. Drill a 3" Diameter hole through the wall. Angle the wall penetration slightly down towards the outside to assist
in draining the condensate away from the unit. If mounting the unit on an inside wall, use the
knockouts provided on the Left and Right sides of the unit to route the piping and wiring connections.
Step 4
Install Mounting Bracket
Locate and secure the mounting bracket to the wall. The Indoor unit weighs a maximum of 46Lbs, use wall anchors and mount
to a wall stud to ensure that the wall is capable of holding the weight of the unit. Use a level to ensure mounting bracket is
leveled, so condensate can drain properly.
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.
Tip: Use Duct tape to tape the Condensate hose (make sure it is below the Line set stubs) and the Defrost Sensor (Heat
Pump only), this makes it easier to guide them though the hole drilled in the wall. Also If possible feed the 14 AWG Interconnect
wiring between Indoor and Outdoor (Maximum # of wires required is 6) through the unit electrical connection (if required by local
codes an electrical connector can be attached to the rear of the unit). Tape the loose wire to the line set stubs.
These two tips save time and prevent damage to the stubs when mounting the Indoor unit.
Note:
Condensate hose is taped below line set stubs. Wrap Duct tape to the end of the condensate hose for easier installation.
Step 6
Install unit on Mounting Bracket. Feed the line set stubs/condensate hose/wiring connections through the 3'' hole, and then
locate the unit key slots onto the tabs on top of 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 also that the wall is plumb.
Step 7
Locate Outdoor unit
Clearances for the Outdoor unit are:
Install the Outdoor unit on a Condenser Pad or if a Heat Pump use feet to raise unit up approx 6'' to allow for defrost to drain
away. 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.
