INFORMATIONAL QUICK GUIDE

1. Determine the square foot of reach room and pick the appropriate indoor unit for that room. Oversizing
is not always better. If the room is too small and the head is too large, the unit will short cycle and not
remove the humidity from the room.
• Up to 350 sq. feet = 9,000 BTU
• Up to 500 sq. feet = 12,000 BTU
• Up to 750 sq. feet = 18,000 BTU
2. Determine where to install the indoor head in each room.
• An exterior wall works best. If it must be on an interior wall you may need a condensate pump to
remove the condensation in the summer. This is purchased separately.
3. Determine where the outdoor unit will be placed.
• Try to place the outdoor unit centrally to all of the indoor units.
• Keep in mind you will need to run 230v power to the unit, so try to keep it close to your electrical
panel in the house.
4. Now that you have the location of the heads in the building and the outdoor unit outside, you will need
to figure out how long each of the line sets will be.
