3.2 Unpacking
Carefully unpack and place the instrument and
accessories in a secure location. Use extra care
while unpacking the Borosilicate glass cylinders.
Ensure that all parts listed in the previous
section are present. Inspect the unit and all
accessories for damage. If you find any damage,
keep all packing materials and immediately
report the damage to the carrier. We will assist
you with your claim, if requested. When
submitting a claim for shipping damage, request
that the carrier inspect the shipping container
and equipment. Do not return goods to Koehler
without written authorization.
3.3 Instrument Installation
The instructions for preparing the equipment
assume that the user is aware of the contents of
this
document
which
lists
the
warranty
conditions and important precautions.
Equipment Placement and Ventilation:
Place
that bath on a firm, level table in an area with
adequate ventilation and environmental control.
The room temperature should not exceed 25°C
(77 °F). Please allow at least 12’’ (30cm) of
open space around each side of the unit in order
for the refrigeration system to work properly.
The unit may be leveled by making minor turning
adjustments to the feet located at the base of
the unit.
Leveling:
For proper operation, the unit should
be leveled. The use of a spirit level will ensure
proper adjustment. To adjust the leveling feet,
use a 13mm open end wrench to loosen the
locknut (upper nut). Adjust the leveling feet
(lower nut) with a 13 mm wrench. When level,
tighten the lock nut.
Filling the Bath:
The bath should be filled with
moisture-free 200 proof ethanol. Please refer to
sections 6.1 and 6.2 for filling and operation
instructions.
Mounting the Brookfield Viscometer:
Attach
the threaded support rod to the support bridge
with the supplied bolt and washer. The threads
should face the back of the unit. Loosen the
screw at the back of the rack and pinion on the
Brookfield Viscometer, and then mount the
viscometer onto the support rod. Tighten the
screw and then adjust the height of the
viscometer using the right thumb screw.
