The air handler is designed so that refrigerant piping
can enter from either the right or left hand side. It is
shipped with the intent that the refrigerant lines will
enter from the left hand side. To convert to right hand
entry, unbraze the elbow on the suction line and rotate
180° and rebraze.
IImmppoorrttaanntt:: Access to refrigerant lines is limited in all
horizontal and some vertical applications.
Therefore, refrigerant lines should be
stubbed out and temporarily capped prior
to setting the air handler. Protect adjacent
surfaces from heat damage when brazing
in and around the air handler. See , p. 12.

The general location of the air handler is normally
selected by the architect, contractor and/or buyer. For
proper installation, the following items must be
considered:
• Available power supply must agree with electrical
data on component nameplate.
NNoottee:: Unit voltage cannot be changed on units
ordered with a VFD.
• If external accessories are installed on the unit,
additional clearances must be provided.
• All duct work should be properly insulated to
prevent condensation and heat loss.
• Refrigerant gas piping must be insulated.
It is recommended that the outline drawings in the
Dimensional Data section be studied and dimensions
properly noted and checked against the selected
installation site. By noting in advance which features
are to be used, proper clearance allowances can be
made for installation and possible future service.
