HANDLING UNIT AFTER REMOVAL 

FROM SKID

The unit will have to be turned sideways and removed 

from the skid to fit through a 36" doorway.  If the door 

height allows, the unit can be slid sideways through the 
door.

If the unit can not be slid through the door, then the unit 
will have to be put on a cart and tipped down to roll 
through the door.  It is recommended that an appliance 
cart by used with a strap to hold the unit on the cart.  The 
wheels of the unit 

must be locked

.  If the wheels were 

allowed to roll, the unit could roll off the cart.  

The unit 

should always be carted from the left side

.  This is the 

side where the compressor is located.  See Figure 4. 

The blade of the appliance cart should be slid under 
the wheels of the unit.  The strap of the appliance cart 
should be placed around the unit and strapped tightly.  
Help will be required to tip the unit back onto the cart.  
The unit can be leaned far enough back to be rolled 
through the door.  Be careful when setting the unit back 
up to keep from damaging the unit.

GENERAL

The equipment covered in this manual is to be installed 
by trained, experienced service and installation 
technicians.  A QWS-Series wall sleeve supplied as a 
separate accessory must be ordered and installed with 
Q-Tec unit.

The unit is designed for use with or without duct work.  
For use without duct work, Plenum Box QPB42 is 
recommended.

These instructions explain the recommended method 
to install the air cooled self-contained unit and the 
electrical wiring connections to the unit.

These instructions and any instructions packaged with 
any separate equipment required to make up the entire 
air conditioning system should be carefully read before 
beginning the installation.  Note particularly “Start 
Procedure” and any tags and/or labels attached to the 
equipment.

While these instructions are intended as a general 
recommended guide, they do not supersede any 
national and/or local codes in any way.  Authorities 
having jurisdiction should be consulted before the 
installation is made.  See Page 3 for information on 
codes and standards.

Size of unit for a proposed installation should be based 
on heat loss calculation made according to methods 
of Air Conditioning Contractors of America (ACCA).  
The air duct should be installed in accordance 
with the Standards of the National Fire Protection 
Systems of Other Than Residence Type, NFPA No. 
90A, and Residence Type Warm Air Heating and Air 
Conditioning Systems, NFPA No. 90B.  Where local 
regulations are at a variance with instructions, installer 
should adhere to local codes.

MINIMUM INSTALLATION HEIGHT

The minimum installation height of the unit with a 
Free Blow Plenum is 8 ft. 6 in.  This provides enough 
clearance for the plenum to be removed.  See Figure 5.

The minimum installation height for ducted 
applications is 8 ft. 4½ in.  This provides enough 
clearance to install the duct work.  See Figure 6.
