2. INSTALLATION

2.1 Installing AFG SLR model fans

NOTE: The AFG SLR model fans are designed to mount behind existing vents. If no

vent exists, one must be installed. Vent should be installed in the upper

center section of the gable.

NOTE: The mounting brackets for the AFG SLR model fans are on sliding rails.

Simply loosen the 8 nuts on the 4 mounting brackets to slide the bracket

into the proper position for your installation. (as shown in Figure 2.1A)

The fan should be flush to the gable vent when installed.

NOTE: The AFG SLR model fans include (8) screws that can be used on masonry or

brick and (8) screws with washers that can be used on wood and shingles.

(see Figure 2.1B)

Installing the QuietCool AFG SLR is very easy. To install the AFG

SLR, simply mount the gable fan to your gable vents as shown in

the following steps:

Flush Mount: The AFG SLR can be mounted flush to a rectangular type louver by fastening through the

mounting brackets to the frame of the louver (as shown in Figure 2.1C)

Fasten the fan to the vent frame studs. Once fastened, tighten the 8 mounting bracket nuts to secure

the fan flush to the gable vent.

Wide Mount: The AFG SLR can be mounted on a wide louver, but additional mounting steps must be

taken in order for the fan to work properly. As shown in Figure 2.1D, two additional boards must be

fastened to the boards framing the gable vent so the AFG SLR can be mounted securely.

Fasten the fan to the vent frame studs. Once fastened, tighten the 8 mounting bracket nuts to secure

the fan flush to the gable vent.

Odd Mount: The AFG SLR can also be mounted off center for an odd shaped louver (as shown in Figure

2.1E).

Any area of the louver that is not covered by the AFG SLR must be sealed off in order to prevent air

leakage, which may hinder performance.

While this is not the most ideal way to mount the gable fan, it is possible. However, since the fan is not

completely covering the vent, maximum airflow will not be achieved.

Fasten the fan to the vent frame studs. Once fastened, tighten the 8 mounting bracket nuts to secure

the fan flush to the gable vent.
