Unpacking and Installation
Shelving
Install the two shelves. While the door is open, apply a high-quality
vacuum grease to the door gasket.
Place the thermometer so that the sensing element is in direct contact with
the top shelf. The dial should be easily visible through the glass door.
Note
It is important to place the sensing element of the thermometer in
direct contact with the shelf or sample that is being heated, in order to
obtain a precise reading of the temperature under vacuum conditions.
Make sure that the dial is clearly visible through the glass door.
s
The unit is supplied with a 3-wire line cord. It should be plugged into an
outlet supplying the correct voltage for the unit and designed for 3-prong
plugs.
For an outlet designed to accept 2-prong (ungrounded) plugs, the best
recommendation is to have a qualified electrician replace it with a new
grounded outlet.
If a plug must be installed, use only the 3-prong grounded type, rated for
the unit load requirements and matching the power outlet. Make sure the
green ground wire is secured to the plug ground post.
Turn the power switch to the OFF position and insert plug into an outlet
meeting the electrical requirements of the unit
