OPERATION
CAUTION:
EXERCISE CARE WHEN USING ACIDIC OR
CAUSTIC SOLUTIONS AS THEY WILL ATTACK
THE GALVANIZED STEEL BATH BODY IF SPILLED
INTO THE BATH. IF SPILLS DO OCCUR, THE BATH
LIQUID SHOULD BE IMMEDIATELY DRAINED AND
THE UNIT THOROUGHLY FLUSHED. SPILLS AND
C O N D E N S A T I O N S H O U L D B E C L E A N E D /
REMOVED FROM ALL METAL SURFACES AFTER
EACH USE.
When filling the bath with water, allowance must be
made for the displacement of water upon immersion
of samples.
CAUTION
WATER LEVEL REQUIREMENTS
MINIMUM LEVEL - WATER LEVEL SHOULD BE
1 1/2 INCHES ABOVE THE PUMP OUTLET.
THIS WILL KEEP THE PUMP FROM RUNNING
DRY AND FAILING TO OPERATE.
MAXIMUM LEVEL - WATER LEVEL SHOULD
NOT BE HIGHER THAN 1 INCH FROM THE TOP
OF THE BATH PAN.
To conserve energy, reduce evaporation and
increase temperature control accuracy, use the
gable cover provided. Do not use aluminum foil as
a cover, as it may cause corrosion due to an
electrochemical reaction.
1.
Add distilled water to bath. Use water levels
as instructed above.
2.
Power up: Depress the power switch located
at the lower right hand corner of the bath. The
unit is fully operational upon application of
power and the display will read actual bath
temperature
3.
To set temperature control point:
a. Press SETPOINT. The display will now
show the current temperature setpoint.
b. Press UP or DOWN until the desired
temperature setpoint is displayed.
c. Press ENTER to store the new value.
d. Display will return to actual temperature.
e. If ENTER is not pressed, new value will
not be set and display will return to actual
temperature.
4.
To adjust temperature offset:
a. Temperature offset should be used to
match a stable bath's actual temperature
display to a calibrated thermometer.
b. Press ENTER until actual temperature is
displayed.
c. While pressing OFFSET, press UP or
DOWN until display shows the
DIFFERENCE
between displayed
temperature and reference thermometer.
Continue holding offset and press ENTER
to set new value.
d. Display should now match your calibrated
thermometer.
e. If ENTER is not pressed, new value will not
be set and display will return to previous
actual temperature.
f.
Example: Setpoint is 37° and actual bath
temperature display is stable at 37°.
Calibrated reference thermometer reads
37.2°. Press OFFSET and UP until display
reads .2. Press ENTER while still holding
OFFSET key. Release keys. Actual bath
temperature will read 37.2°. Readjust
setpoint to 37° by repeating step 3.
NOTE
AS WATER BATHS ARE OPERATED,
ESPECIALLY AT ELEVATED TEMPERATURES,
CONDENSATION WILL FORM ON THE
UNDERSIDE OF THE GABLE COVER. THE
AMOUNT OF CONDENSATION CAN BE
CONSIDERABLE. CARE SHOULD BE
EXCERCISED WHEN REMOVING THE COVER
SO THAT WATER WILL FALL BACK INTO THE
BATH CHAMBER, AND NOT ON THE BATH
SURFACE. THE COVER SHOULD BE PLACED
UPSIDE DOWN WHEN REMOVED TO MAINTAIN
A DRY WORK AREA.
