STAINLESS STEEL FLUID HEATER
READ THIS MANUAL CAREFULLY BEFORE INSTALLING,
OPERATING OR SERVICING THIS EQUIPMENT.
It is the responsibility of the employer to place this information in the hands of the operator. Keep for future reference.
GENERAL DESCRIPTION
The Aro stainlesssteel fluidheater modelsare wiredfor 220volt ACap-
plications. The heatingelementis a2000 wattcartridgetype andisther-
mostatically controlled.The wiring, heatingelement and thermostatare
protected by a preset heat limiter.
The thermostatis adjustable upto approximately 121_ C(250_ F). The
heater isoff whenthe thermostat knobisturned counterclockwiseas far
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 electricalsection and internally
spiraling material section. The material enters the base under line
pressure fromthe pumpand isheated anddelivered thru tothe ma-
terial outlet at the top.
• Twoormorepaintheatersmay becoupledtogetherbyplumbingthe
material outletof the firstheater to the material inlet of thenext, etc.
However,the distanceofpipingrunbetween theunitsshouldbelim-
ited to no more than three feet (see figure 4, page 4).
TYPICAL INSTALLATION
The heater inlet and outlet should be plumbed (up flow) as shown (see
figure 4,page 4),to minimize chances oftrapped airinside the heater.If
theinlet andoutletarereversed (downflow),thetemperature rise willbe
different.

OPERATING PRECAUTIONS
•
Heed all warnings.
WARNING
Do not exceed 35 MPa (5000 p.s.i.) maximum.
WARNING
HIGH PRESSURE DEVICE. Improper usage of
this equipmentcouldresult inseriousinjury.The possibilityof
injection into the flesh is a potential hazard. Never allow any
part of thehuman body to comein front of,or in directcontact
with, the material outlet. An injection injury can be serious. If
injection shouldo ccur, contactaqualified physicianfor imme-
diate treatment.
CAUTION
Electrical supplypower to theh eater must beoff
during flushing operation.
CAUTION
Use only genuine Aro replacement p arts to as-
sure compatible pressure rating and longest service life.
CAUTION
Do not remove cover when energized.
