INSTALLATION (See Figure One)
Local city, county or other ordinances may govern the use of this equipment. If you
have any questions about local requirements, please contact the appropriate local
agency. Installation may be performed by the end user.
Under normal circumstances this unit is intended for use indoors, at room temperatures
between 5°and 40°C, at no greater than 80% Relative Humidity (at 25°C) and with a
supply voltage that does not vary by more than 10%. Customer service should be
contacted for operating conditions outside of these limits.
3.1 Power Source: The electrical supply circuit to the oven must conform to all
national and local electrical codes. Consult the oven’s serial data plate for the
voltage, and ampere requirements before making connection. VOLTAGE
SHOULD NOT VARY MORE THAN 10% FROM THE SERIAL PLATE RATING.
This unit is intended for 50/60 Hz application. A separate circuit is recommended
to prevent possible loss of product due to overloading or failure of other
equipment on the same circuit.
3.2 Location: When selecting a site for the oven, consider all conditions which may
affect performance, such as extreme heat from steam radiators, stoves, ovens,
autoclaves, etc. Avoid direct sun, fast-moving air currents, heating/cooling ducts,
and high traffic areas. To ensure air circulation around the unit allow a minimum
of 30 cm between the unit and walls or partitions which might obstruct free
airflow.
3.3 Lifting / Handling: These units are heavy and care should be taken to use
appropriate lifting devices that are sufficiently rated for these loads. Units should
only be lifted from their bottom surfaces. Doors, handles and knobs are not
adequate for lifting or stabilization. The unit should be completely restrained
from tipping during lifting or transport. All moving parts, such as shelves and
trays should be removed and doors need to be positively locked in the closed
position during transfer to prevent shifting and damage.
3.4 Leveling: The unit must sit level and solidly. The Model 1410 has four rubber
feet that are already attached to the unit and are not adjustable. Leveling feet
are supplied with Model 1430 and must be installed in the four holes in the
bottom corners of the unit. With the unit standing upright, turn the leveling feet
counterclockwise to raise the level of that corner. Adjust the leveling foot at each
Section

corner until the unit stands solid and level. If the unit must be moved, turn the
leveling feet in all the way (clockwise) to prevent damage while moving.
3.5 Cleaning: The oven interior was cleaned at the factory, but not sterilized.
Remove all shelving and clean with a disinfectant that is appropriate to your
application. DO NOT USE chlorine-based bleaches or abrasives as they will
damage stainless steel surfaces. DO NOT USE spray cleaners that might leak
through openings and cracks and get on electrical parts or that may contain
solvents that will harm the coatings. A similar periodic cleaning is recommended.
WARNING: Never clean the unit with alcohol or flammable cleaners with the unit
connected to the electrical supply. Always disconnect the unit form the electrical
service when cleaning and assure all volatile or flammable cleaners are evaporated
and dry before reattaching the unit to the power supply.
3.6 Shelves: See FIGURE ONE for proper orientation of shelves within specific
chamber. DO NOT place items directly on the floor of the chamber.

CONTROL PANEL OVERVIEW (See Figure Two)
4.1 POWER: The main power I/O (ON/OFF) switch must be in the I/On position
before any electrical systems are optional.
4.2 HEATING: This pilot lamp is on when the temperature controller has activated
the heating elements to reach and maintain set point.
4.3 TEMPERATURE CONTROLLER: This is the manually adjustable temperature
controller marked SET TEMPERATURE. Its dial is marked from 0 to 10 and is
adjustable across this scale. A clockwise adjustment raises the temperature.
4.4 VACUUM: This adjustment valve, located on the right of the panel, allows
opening and closing of the piping system to an external vacuum pump or system.
4.5 VENT: This adjustment valve, located on the left of the panel, controls the
vacuum release to return the chamber to atmospheric pressure.
4.6 VACUUM GAUGE: This component indicates the chamber operating pressure
in inches of mercury.
