5 Operation
5.1 Refrigerated Test Chamber
Remove the Chamber lid
(Figure 3, Item 9)
and
fill the test chamber with Dry Denatured Ethanol
as specified in section 1.3. Fill the bath with the
medium
to within about 1” (2.54cm) from the top of
the grease cylinder sleeve. Approximately 20
Gallons or 75.71 Liters will be required. Additional
medium may need to be added as fluid is cooled
to appropriate test temperature.
NOTE:
Do not attempt moving the bath
when filled with fluid medium. Drain all fluid before
moving or relocating the instrument. Sudden
starting and stopping could result in cold bath fluid
being forcefully ejected from the bath.
5.2 Power
Press on the compressor switch, See
Figure 4,
Item 12
. This turns on the refrigeration system of
the instrument.
WARNING:
Do
NOT
turn the compressor on
unless the bath is filled with the proper medium;
otherwise, damage may occur to the unit and the
warranty would be void.
Set Chamber Temperature Controller
(Figure 4,
Item 16)
to desired testing temperature. The
scope of ASTM D1092 covers a testing range
down to -54°C. Refer to section 4.5 for detailed
operation
instructions
for
the
temperature
controller.
NOTE:
Allow for the test chamber to cool
and come to temperature equilibrium prior to
turning on Drive Motor / Recirculating Pump
(See
Figure 4, Item 13)
. It may take approximately 8
hours for temperature equilibrium at -54°C and
having the gear pump and operating during this
time will only cause unnecessary wear to its
components.
5.3 Calibrate Hydraulic System
Prior to calibrating the hydraulic system, check
and confirm that the hydraulic oil reservoir is filled
with hydraulic oil at least ¾ of its entire volume.
The hydraulic oil in the reservoir will come to
temperature
equilibrium
with
the
chamber
temperature during the cooling period.
If the reservoir is not filled with hydraulic oil, fill
the reservoir with the appropriate amount of oil
(3/4 of the reservoir cylinder volume) and allow for
sufficient time for the oil to come to equilibrium
with the chamber temperature.
After the test chamber medium and hydraulic oil
has obtained equilibrium at the desired test
temperature, the hydraulic system must be
calibrated at that temperature.
1.
To calibrate the hydraulic system, first connect
the Calibration Piping Assembly
(Figure 1,
Item G)
to the Hydraulic System Connection
Port
(Figure 3, Item 11)
using the quick
connect coupling. Refer to Figures 7 and 8
below.
