Basic Installation Design and
Application Planning
Successful unit installations require proper planning
and site inspection before installation begins. Before
installing the unit, make sure that all service and
airflow clearances are met and that the unit can meet
all applicable code and regulation requirements.
Provide an inspection of both the inside and outside of
the structure by reviewing floorplans and/or visiting the
installation site.
Mounting the Unit
The unit is shipped with the compressor secured to
the compressor rails with two (2) shipping brackets.
Although the unit will perform as designed with the
shipping brackets in place, there may be an increase
in noise and vibration levels. Remove and discard the
shipping brackets once unit is positioned at its final
installation location (see Figure 12).
When installing a Q-TEC unit near an interior wall on
the left side, a minimum of 8" is required but 12" is
preferred.
When installing a Q-TEC unit near an interior wall
on the right side, a minimum of 18" is required as
additional space is needed to connect the side drain.
If rear condensate drain kit QCDS48 is used, the
minimum can be reduced to 8".
This clearance is required to allow for the attachment of
the unit to the sleeve and side trim pieces to the wall.

clearance to combustible material.
Following are the steps for mounting the Q-TEC.
