Top-mounted gauges may ship separately to prevent the possibility of
shipping damage to the gauge enclosure and gauges. In this case some
simple installation will be required. The gauge(s) will ship installed in an
enclosure which will be screwed to the top of the SAH. Pressure taps will
be supplied on the housing on each side of the filter. These will be
required to be connected to the gauge, using 1 ⁄
4
" diameter clear plastic
tubing, as shown in Figures 5 and 6. When the gauge option is ordered the
tubing will be supplied by AAF with the gauge and gauge enclosure. Refer
also to the specific installation instructions supplied with the gauge(s).
If pressure gauge(s) have not been included in the customer’s purchase
order discuss the pressure gauge options with your AAF representative.
3.12 Fans: Sometimes the SAH may be supplied with an internally
mounted fan. See the AAF submittal drawing and wiring diagram for
information and details. In order for the fan to be operated some or all
of the following installation steps may be required:
