Heater/Circulator
The Hanson Phase One Disintegration Tester is integrated with
the PolyScience LX Immersion Circulator for control of bath
temperature. The following is a quick guide for entering the set
point temperature and working with the unit. Please refer to the
instruction manual included with the tester for complete
instructions. Electronic copies of the manual (LX Immersion
Circulator Operator’s Manual 110-874 PSC/EN) may be
obtained from www.polyscience.com
Turn on the Power to the Heater/Circulator
The PolyScience LX Immersion Circulator has its own power
supply. The power switch is located partway down the back side
of the heater towards the right edge (as viewed from the front).
The toggle switch is oriented for vertical activation (toggle to the
top—ON, toggle to the bottom—OFF).
When the heater is powered on, the display will light up and
indicate the current water temperature in the middle of the
display and the target temperature in the lower right.
WARNING!
The maximum possible temperature able to be set
for the heater is 98 °C (factory-set limit). However, to avoid
distortion of the waterbath, bath lid, and baskets, and to protect
the tester warranty, the heater should never be allowed to run
higher than 55 °C.
Note: As a safety feature, the heater/circulator function will not
turn on, or will shut itself off, when the water level falls below the
minimum limit marked on the front of the heater.
Do not set heater
above 55 °C
