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
pipe support spacing lengths as shown in the General
Refrigerant Piping System Information section. Refer
to the "Pipe Supports" section for information on using
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.
