Piping Design and Layout

The piping design and layout are critical factors for the overall performance and reliability of the
system. Find the desired locations for each indoor unit and the outdoor unit. Then measure and
record the piping lengths and heights as directed below to qualify the piping design and layout.

First, measure and record the piping length (L1,L2, L3….Ln) from the outdoor unit to each indoor unit.

NOTE:

Min. refrigerant line length between the indoor and outdoor units is 10 ft. (3 m).

L1=

L2=

L3=

L4=

L5=

Second, find the indoor units with the greatest vertical distance from the outdoor unit. Measure the maximum
vertical height (H1) from the bottom of the outdoor unit to the bottom of the highest mounted indoor units.

H1=

Third, find the two indoor units with the greatest vertical distance from each other. Measure the maximum
vertical height (H2) between those two indoor units from bottom of one unit to bottom of the other unit.

H2=
