WARNING: During the installation or reinstallation of the instrument, ensure that the
external connecting cables (i.e., data, RS232 etc.) are placed separate from the mains
power cables. Also, ensure that the external connecting cables and the mains power
cables are placed away from any hot external parts of the instrument.
Note: Ensure that the mains power cable is selected such that it is suitable for the
instrument that is being installed or reinstalled, paying particular attention to the
current rating of both the cable and the instrument.
WARNING: Before switching the instrument on, apply the air to the instrument and
switch on the water supply to the Peltier system (if used).
WARNING: During operation, extreme hot or cold surfaces may be exposed. Take
adequate precautions. Wear safety gloves before removing hot or cold geometries.
WARNING: Liquid nitrogen can cause rapid suffocation without warning. Store and
use in an area with adequate ventilation. Do not vent liquid nitrogen in confined
spaces. Do not enter confined spaces where nitrogen gas may be present unless the
area is well ventilated. The warning above applies to the use of liquid nitrogen.
Oxygen depletion sensors are sometimes utilized where liquid nitrogen is in use.
WARNING: The various surfaces and pipes of the ETC and the supply Dewar can get
cold during use. These cold surfaces cause condensation and, in some cases, frost to
build up. This condensation may drip to the floor. Provisions to keep the floor dry
should be made. If any moisture does drip to the floor, be sure to clean it up promptly
to prevent a slipping hazard.
WARNING: Always unplug the instrument before performing any maintenance.
WARNING: No user serviceable parts are contained in the rheometer. Maintenance
and repair must be performed by TA Instruments or other qualified service personnel
only.
WARNING: This instrument must be connected to an earthed (grounded) power
supply. If this instrument is used with an extension lead, the earth (ground) continuity
must be maintained.
