Installing an Aftercooler (Optional)
You can add an aftercooler to the D Carousel Dryer by ordering the optional after-
cooler assembly. Installation is easy.
The optional aftercooler requires a source of city, tower, or chiller water and a dis-
charge or return line. You can use water at temperatures up to 85°F (30°C). But the
water flow should be at least 1 gal/min (3.8 liters/min) for models D15, D25, D50;
or 2 gal/min (7.6 liters/min) for models D75 and D100.
1 Stop the dryer and lockout the main power.
2 Remove the cover plate from the right side of the aftercooler housing on the
dryer by removing the five screws.
3 Inspect the condition of the gasket. If the gasket is damaged, replace the
gasket.
4 Insert the aftercooler assembly into the aftercooler housing. Make sure the
staggered holes in the aftercooler mounting plate align with the holes in the
aftercooler housing.

TIP: Make the water supply and dis
charge / return connections with
flexible hoses at least 24 in. (61 cm)
long. This allows you to easily
remove the aftercooler assembly for
cleaning.
✒
TIP: If an optional flow control is also
being installed with the aftercooler,
the manual shut off valve should be
installed on the inlet line for the flow
control.
