INSTALLATION
WARNING
INSTALLATION SHOULD BE COMPLETED BY
QUALIFIED PERSONNEL ONLY.
5.01 1. The most uniform operating conditions and
results will be obtained by placing the bath on
a level surface in an area remote from drafts,
ventilating outlets, radiators, and other rapidly
changing ambient conditions.
2. Place the stainless steel metal shelf
(corners facing downward) inside the bath
chamber. The shelf (Diffuser Pan) provides
a sample base and protects samples from
touching the hot metal bath bottom. If it is
necessary to increase the height of the diffuser
pan, a Leg Extension Kit is included for this
purpose, except for the Model 2829/2830.
Following the figure shown below, attach the
4 extension legs to each of the four corners of
the diffuser pan.

WARNING
FOR PERSONAL SAFETY, THIS APPARATUS MUST
BE PROPERLY GROUNDED.
1.
The power cord provided on this unit is
equipped with a three-prong (grounding) plug
which mates with standard three-prong
grounding wall receptacle to minimize the
possibility of electric shock hazard from this
apparatus. If in doubt the user should have the
wall receptacle and circuit checked by a
qualified electrician to make sure the
receptacle can provide adequate current and
is properly grounded.
2.
Where a standard two-prong wall receptacle
is encountered, it is the personal responsibility
and obligation of the user to have it replaced
with a properly grounded three-prong wall
receptacle.
circumstances, cut or remove the third
(ground) prong from the power cord. Do
not use a two-prong adapter plug.
5.03 Determine the total amount of current being
used by other apparatus connected to the
circuit that will be used for this apparatus. It
is critical that the added current demand (see
nameplate) of this and other equipment used
on the same circuit does not exceed the
rating of the fuse or circuit breaker.
