Unpacking and Installation

The shipping carton should be inspected upon delivery. When received,
carefully examine for any shipping damage before unpacking. If damage is
discovered, the delivering carrier should both specify and sign for the
damage on your copy of the delivery receipt.

Open the carton carefully making certain that all parts are accounted for
before packaging materials are discarded. After unpacking, if damage is
found promptly report it to the carrier and request a damage inspection
promptly.

Important 

Failure to request an inspection of damage within a few days

after receipt of shipment absolves the carrier from any liability for damage.
You must call for a damage inspection promptly.

Place the oven near an electrical outlet meeting the requirements stated on
the name plate and in a location away from drafts and free from wide
temperature variations.

Allow enough space around the oven for the free circulation of air. Heat
escaping through the oven walls and top must be carried off by normal
convection. Do not place oven near an open window, radiator or ventilator.
It must not be placed on a combustible surface or be stacked directly on
top or under another oven. If a vacuum pump or insert gas source will be
used, allow room for the equipment.

To operate the unit as a vacuum oven, connect 1/4-inch ID tubing to valve
on either side. Connect the other end of the tubing to your vacuum pump.
