INSTALLATION INSTRUCTIONS

MOUNTING THE UNIT

When installing a QC

 

unit near an interior wall on the 

left side, a minimum of 8" is required; 12" is preferred.

When installing a QC

 

unit near an interior wall on the 

right side, a minimum of 12" is required as additional 
space is required to connect the drain. 

This clearance is required to allow for the attachment 
of the unit to the wall mounting brackets and the side 
trim pieces to the wall.

This unit is to be secured to the wall with the wall 
mounting brackets provided.  The unit itself, the supply 
duct, and the free blow plenum are suitable for “0” 
clearance to combustible material.

NOTE:

  When a wall sleeve is to be used discard the 

brackets shipped with the heat pump and 

attache the unit to the sleeve with bracket 

supplied with the wall sleeve.

Following are the steps for mounting the QC units; for 
reference see Figure 13.

1.  Attach wall mounting bracket to the structure wall 

with field-supplied lag bolts.  The fluid piping 
connections are to be within the confines of this 
bracket.  See Figure 1 for cabinet openings and 
location of fluid coil connection points.

2.  Position the unit in front of the wall mounting 

bracket.

3.  Remove the locking screws from the wheels.  Refer 

to Figure 12. 

 

4.  Roll the unit up to the wall mounting bracket.  

The unit must be level from side to side.  If any 
adjustments are necessary, shim up under the 
rollers with sheets of steel or any substance that is 
not affected by moisture.

5.  Secure the unit to the wall bracket with provided 

#10 hex head sheet metal screws.  There are 
prepunched holes in the cabinet sides, and 
the bracket has slotted holes to allow for some 
misalignment.

6.  Position the bottom trim piece to the unit and 

attach with provided screws (dark colored).

7.  Position side trim pieces to the wall and attach 

with field-supplied screws.  There are two long and 
two short pieces supplied.  The long pieces are to 
enclose the gap behind the unit.  The short pieces 
are to fill the gap behind the cabinet extension or 
the free blow plenum box.  They may be cut to suit 
the ceiling height or overlap the unit side trim.  
There is sufficient length to trim up to a 10'-2" 
ceiling.
