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.
