5.3 HEATER COOLING CONNECTIONS: Each Model 5194 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 1/4-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 5194 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 5194 heater.
Proper coolant flow must be maintained during operation of the heater. See Section 3 –
Specifications for required cooling water and compressed air flow for each Model 5194
heater size.
5.4 ELECTRICAL
CONNECTIONS: The T3 lamp of the Model 5194 is
electrically wired to an intermediate terminal block within the heater.
Each heater is supplied with an 8-foot (2.4 m) electrical cable. If ordered with the
controller option, this cable is directly hard wired into the Model 5420 power controller.
