REFRIGERANT PIPING CONNECTIONS
Installation Overview
Installation
Single Zone Wall-Mounted systems are one-to-one
systems. There is a direct piping connection between the
outdoor unit and the indoor unit. The figure at right illus-
trates the basic pipe connections between the outdoor
and indoor unit. Refer to the illustration when proceeding
with pipe connections.
This illustration shows the indoor unit being installed at
a higher position than the outdoor unit. However, if the
outdoor unit be installed at a higher position than the
indoor unit, the basic pipe connections are the same.
Refer back to the tables within the "Connection Limita-
tions" section for specific length limitations in conjunction
with outdoor unit and indoor unit positioning.
• When proceeding with piping connections, adhere to
clamps and pipe support materials.
• Always adhere to local codes regarding piping and
accurate support spacing along the piping system.
• Always include insulation on all refrigerant and drain
piping to ensure condensate does not form and cause
damage to walls, floors, etc.
