GENERAL DESCRIPTION

(223.8 mm)  
The Aro stainless steel fluid heater models are wired for 220 volt AC ap-  
plications. Theheatingelement isa2000wattcartridgetypeandisther-  
mostatically controlled. The wiring, heating element and thermostat are  
protected by a preset heat limiter.  
The thermostat is adjustable up to approximately 121_ C (250_ F). The  
heater isoffwhenthethermostat knob isturned counterclockwise asfar  
as possible. The heater will not switch on until the knob is rotated to at  
least ambient room temperature.  
Fluid heaters have been tested in water soluble oil. Some of this fluid  
may be left within the heater, therefore flush out this fluid with a solvent  
compatible with the material to be pumped.  
This unit utilizes an explosion-proof electrical section and internally  
spiraling material section. The material enters the base under line  
pressure from the pump and is heated and delivered thru to the ma-  
terial outlet at the top.  
Twoormorepaintheatersmaybecoupledtogetherbyplumbingthe  
material outlet of the first heater to the material inlet of the next, etc.  
However,thedistanceofpipingrunbetweentheunitsshouldbelim-  
ited to no more than three feet (see figure 4, page 4).

OPERATING PRECAUTIONS  
Heed all warnings.  
WARNING Do not exceed 35 MPa (5000 p.s.i.) maximum.  
WARNING HIGH PRESSURE DEVICE. Improper usage of  
thisequipment couldresult inseriousinjury. Thepossibilityof  
injection into the flesh is a potential hazard. Never allow any  
part of the human body to come in front of, or in direct contact  
with, the material outlet. An injection injury can be serious. If  
injection shouldoccur, contactaqualifiedphysician forimme-  
diate treatment.  
CAUTION Electrical supply power to the heater must be off  
during flushing operation.  
TYPICAL INSTALLATION  
CAUTION Use only genuine Aro replacement parts to as-  
sure compatible pressure rating and longest service life.  
CAUTION Do not remove cover when energized.  
The heater inlet and outlet should be plumbed (up flow) as shown (see  
figure 4, page 4), to minimize chances of trapped air inside the heater. If  
theinletandoutletarereversed(downflow), thetemperaturerisewillbe  
different.
