Heater Cooling Connections
Each Model 5209 is designed with three ‘quick-disconnect’ fittings protruding from the top of
the heater cover. The two fittings located at the outer ends of the heater are the inlet/outlet
cooling water ports. The single fitting located at the center of the heater is the cooling air inlet
port.
All three fittings accept ½-inch outer-diameter flexible nylon tubing. A 30-ft. (9.1 m) length of
tubing and three additional quick-disconnect fittings are shipped with each Model 5209 heater.
The tubing should be cut to specific lengths so that both cooling water and compressed air can
be supplied to the heater. The additional fittings should be used for connecting the tubing
directly to the cooling water and compressed air source.
Once cut to the appropriate lengths, each individual tube length should be inserted into the
appropriate fittings on both the heater and the cooling water and compressed air sources.
Figure 5-2 details a typical installation for the Model 5209 heater.
Note: Fitting plugs are placed into the two water coolant fittings as shipped from the factory. Both of these plugs
must be removed from their respective fittings prior to inserting the flexible tubing. These plugs can either be kept
for future use or discarded. See Figure 4-1 for detail.
