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.

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.

PRECAUTIONS
THIS IS NOT AN EXPLOSION PROOF OVEN.
5.1 Do not place or use explosive, combustible, or flammable materials in the
oven.
5.2 Do not use sealed containers in the oven chamber.
5.3 Do not cut or remove the ground prong from the power cord or use an
ungrounded 2-prong adapter plug.
5.4 Disconnect the unit from the electrical power source before attempting to
make any repairs or component replacements.
5.5 If a mercury thermometer is used and breakage should occur, all spilled
mercury must be completely removed from the chamber.
5.6 THIS OVEN IS NOT SUITABLE FOR USE IN CLASS I, II, OR III
LOCATIONS AS DEFINED BY THE NATIONAL ELECTRICAL CODE
NFPA 70.
5.7 This oven is not intended, nor can it be used, as a patient connected device.

VACUUM OPERATION (See Figure Two)
6.1 IT IS IMPORTANT TO USE VACUUM TUBING FOR ALL THE VACUUM
HOOKUPS. OTHER TYPES OF TUBING MAY COLLAPSE AND
PREVENT COMPLETE EVACUATION.
6.2 A pump with a pumping capacity four times greater than the chamber
volume is advisable. For example a 1410 has a chamber volume of one (1)
cubic foot so a pump with a pumping capacity of four (4) cubic feet per
minute is recommended. When working below 1mm, a diffusion type pump
will be needed. See unit specifications for chamber capacities.
6.3 Vacuum: To apply vacuum to the chamber attach the hose from the
vacuum pump to the larger 3/8" hose connection on top of the oven. Close
the VENT valve and open the VACUUM valve. Latch the door shut and start
the vacuum pump. Be certain the vacuum valve is open and the VENT
valve is closed. This action will hold the door shut and against the gasket
until the pump creates a vacuum in the chamber. Once a good vacuum seal
is accomplished, the door will hold itself shut and sealed until the chamber is
returned to atmospheric pressure.
6.4 Watch the VACUUM GAUGE and when the required vacuum is obtained,
close the VACUUM valve and turn the pump off. The VACUUM GAUGE is
incremented from zero to 30 inches of Hg (76 cm of Hg) with zero
representing atmospheric pressure. The oven can be evacuated to
pressures as low as 10 microns.
6.5 Vacuum Release: To return the chamber to atmospheric pressure, open
the VENT valve very slowly and allow the chamber to re-pressurize. The
speed of pressurizing can be controlled by how much the valve is opened.

OPERATION
NOTE: Slight vapor or smoke may occur in the initial heat-up. This is the
dissipation of protective coatings that have been applied to the oven
elements.
7.1 Power Supply: Connect the service cord to a grounded outlet and push the
power switch to the I/ON position. If supplied with a detachable cordset,
plug the female end into the inlet of the unit and the male plug into the
supply. Assure that units requiring a fuse have a fuse installed. This fuse
may be at the inlet or part of the cordset male plug.
7.2 Place a reference thermometer inside the chamber where it can be easily
viewed through the window. Then vacuum down the chamber as described
in Section 6.0
7.3 Setting Temperature: The temperature control dial is marked from 0-10.
These scale numbers do not represent temperature but are to be used as a
reference guide. The operating range is 40°C - 200°C. The dial should be
used according to the operating range. To set the temperature control, turn
the knob clockwise to the setting on the dial that is just above the
approximate operating temperature desired. The HEATING light will come
on indicating that the oven is heating. Allow the unit to heat until the
reference thermometer has reached the desired temperature. When the
desired temperature has been reached, turn the control knob
counterclockwise just until the HEATING light goes off. Allow the unit to
stabilize for several hours. Re-adjust the control knob up or down as
required until the desired temperature is obtained. Allow the unit to stabilize
between each setting. Temperature stability is obtained when the HEATING
light circulates on and off to maintain set point and the temperature value in
the chamber remains consistent.

MAINTENANCE
NOTE: Prior to any maintenance or service on this unit, disconnect the service
cord from the power supply.
8.1 Cleaning: Disinfect the oven interior on a regular basis. To prepare the
oven for cleaning remove the shelves and door gasket. The shelves and
door gasket are autoclavable.
A. First clean removed parts and interior with soap and water. To
decontaminate use a disinfectant that is suitable to your
application. DO NOT use chlorine based bleaches or
abrasives as this will damage stainless steel surfaces.
B. When washing the gasket, handle carefully so as not to impair
the positive seal.
8.2 If the oven is to be shut down for storage or transporting, remove shelves
and latch the door closed. Screw the leveling feet in on the 1430. See
Section 3.3 for transport procedures.
8.3 There is no maintenance required on the electrical components. If the oven
fails to operate as specified, see Troubleshooting before calling for service.
