INSTALLATION INSTRUCTIONS

MOUNTING THE UNIT

When installing a Q-T

ec

 

unit near an interior wall on 

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

When installing a Q-T

ec

 

unit near an interior wall on 

the right side, a minimum of 18 inches is required as 
additional space is required to connect the side drain.  
If the rear condensate drain kit QCDS48 is used the 
minimum can be reduced to 8 inches.

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

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

Following are the steps for mounting the Q-T

ec

.  F

or 

reference see Figure 13A for external mounting bracket 
or 13B for internal bolt secured bracket (recommended).

 

1.  Attach mounting brackets to the wall sleeve with 

screws provided.  Either use external mounting 
bracket (Fig. 13A) or internal bolt bracket (Fig. 13B).

 

2.  Position the unit in front of the sleeve with the 

condenser section toward the sleeve.

 

3.  Remove the locking screws from the wheels.  

Refer to Figure 14. 

 

 

4.  Roll the unit into the sleeve.  Make sure to check 

both sides of the unit as it is being rolled to 
keep it centered in the sleeve.  Also check the 

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

 

5.  Make sure the gasket on the rear of the unit is 

touching the sleeve across the top and down both 
sides.  This is a rain water seal.

 

6.  Secure the mounting brackets to the unit with 

screws provided, #10 hex head sheet metal 
screws (Figure 13A) or use nut and washer to 
secure sleeve (Figure 13B).

 

7.  Bottom trim extensions are provided for use when 

wall is less than 14 inches but greater than 10.5 
inches.  Secure to wall with screws (not provided).

 

8.  Attach the bottom trim piece to the unit with the 

screws provided (dark colored).

 

9.  Position side trim pieces to wall and attach with 

field supplied screws.  There are two long pieces 

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 your ceiling height or overlap 

the unit side trim.  There is sufficient length to 

trim up to a 10'2" ceiling.

NOTE:  If the exterior wall thickness is between 5    

 inches to 10.5 inches, a side trim extension   
piece kit, model QSTX42, is available.
