GENERAL DESCRIPTION
The Aro stainless steel fluid heater models are wired for 120, 230 / 240
and 415 / 440 volt AC applications. The heating element is a 2000 watt
cartridge type and is thermostatically controlled. The wiring, heating
element and thermostat are protected by a preset heat limiter.
The thermostat is adjustable up to 250_ F (121_ C). The heater is off
when the thermostat knob is turned counterclockwise as far as posĆ
sible. The heater will not switch on until the knob is rotated to at least
ambient room temperature.
Fluid heaters have been tested in a water solution. 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 explosionĆproof 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 maĆ
terial outlet at the top.

OPERATING PRECAUTIONS
• Heed all warnings.
WARNING Do not exceed 5000 p.s.i. (35 MPa) maximum.
WARNING HIGH PRESSURE DEVICE. Improper usage of
this equipment could result in serious injury. The possibility of
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 should occur, contact a qualified physician for immeĆ
diate treatment.
• This unit is CSA certified for Class I, Division 1, Group D, HazardĆ
ous Locations, Temperature Code (identification number) T3.
• Two or more paint heaters may be coupled together by plumbing
the material outlet of the first heater to the material inlet of the next,
etc. However, the distance of piping run between the units should
be limited to no more than three feet (see figure 4, page 4).
CAUTION Electrical supply power to the heater must be off
during flushing operation.
CAUTION Use only genuine Aro replacement parts to asĆ
sure compatible pressure rating and longest service life.
TYPICAL INSTALLATION
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
the inlet and outlet are reversed (down flow), the temperature rise will
be different.
