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.
LOCATION:
Place the unit where it will be operated, away from drafts and wide
variations in ambient temperature. It should be near a power source that
matches the unit nameplate requirements. Allow clearance around the unit for
free air convection, hose/accessory attachment and user-access. DO NOT put
the oven on top of or underneath another oven, or on a combustible surface.
HOSE CONNECTIONS:
Connect a ¼-inch ID vacuum hose to the left hose connector on the
control panel that is marked "EVACUATE". Connect the other end of the hose
to a vacuum pump.
If operation will include replacing the vacuum in the chamber with an inert
gas such as carbon dioxide or nitrogen, connect a ¼-inch ID flexible hose to the
right hose connector that is marked "VENT" and to the regulator for the gas
supply. DO NOT use combustible, flammable or corrosive gases.
ELECTRICAL CONNECTION:
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—refer to the upcoming wiring
schematics if necessary.
Turn the power switch
OFF
and insert the plug into the outlet.
FOR SERIES 3618 UNITS
ONLY
: Turn the power switch to the
OFF
position.
For the 120V unit, plug the power cord into a grounded 20-amp outlet; for the
240V unit, attach proper power plug to match the power outlet.

THERMOMETER:
For models using the dial thermometer—3608, 3608-1CE, 3618 and
3618-1CE—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.
Models with the LED display of temperature—3608-5, 3608-6CE, 3618-5
and 3618-6CE—are easily identifiable with the LED positioned just below
the power switch.
Model 3608MP features a microprocessor based temperature controller
with an incorporated display.
