INSTALLATION
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).
The unit should now be unpackaged, removed from the
skid and placed on a level floor near its install location.
If the front doors are not aligned when closed, six (6)
nylon washers have been provided, located on each
door hinge, to be moved as needed to adjust the door
alignment.
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.
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-TEC
.
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
(Figure 13A) or internal bolt bracket (Figure 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 (see
Figure 14 on page 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).
