INSTALLATION
SECTION 4
FIGURE 3 RECOMMENDED INSTALLATION DETAIL
4.5 FREEZE PROTECTION
If the aftercooler is to be installed in a location where ambient
temperatures may fall below 35
o
F, heat tracing and/or insula-
tion must be used on the outlet piping to the separator, the
separator, and the drain piping. The aftercooler must be
protected from the direct wind, i.e. a roof and/or walls.
The aftercooler should be turned off when ambient tempera-
tures fall below 35
o
F.
4.6 SEPARATOR INSTALLATION
CAUTION
WHEN INSTALLING THE SEPARATOR, NEVER REDUCE
THE PIPING SIZE BETWEEN THE AFTERCOOLER AND
SEPARATOR. THIS MAY CAUSE INADEQUATE
DRAINING OF THE AFTERCOOLER AND POSSIBLE
BACK PRESSURE OR INCREASED PRESSURE DROP.
IF THE SEPARATOR DRAIN IS TO BE CONNECTED
INTO A REMOTE OR COMMON DRAIN LINE, MAKE
SURE THAT IT IS VENTED.
THE DISCHARGE FROM THE SEPARATOR MAY
CONTAIN COMPRESSOR LUBRICANTS. COMPLY WITH
ALL REGULATIONS CONCERNING DISPOSAL OF SUCH
FLUIDS.
When the system air is cooled by the aftercooler, moisture in
the compressed air condenses and accumulates in the outlet of
the aftercooler. To efficiently remove this liquid from the air
system, a separator with a FD-1 float drain must be installed
immediately downstream of the aftercooler.
Install the separator as outlined in the Installation, Operation,
and Maintenance Instructions supplied with the component. If
a separator was not ordered with the aftercooler, one can be
ordered from your VAN AIR distributor.
