INSTALLATION
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, cycle wattage 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 any walls or partitions and the unit
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 1470 has rubber feet that are already
attached to the unit and are not adjustable. Leveling feet are supplied with Models 1480 and
1490, and must be installed in the four holes in the bottom corners of the unit. With the unit
standing upright, turn the leveling foot counterclockwise to raise the level of that corner. Adjust
the leveling foot at each 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 shelves and
shelf clips and clean with a disinfectant that is appropriate for 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.
3.5 Shelves: See Figure 1 for proper orientation of shelves within the individual model chambers.
DO NOT place items directly on the floor of the chamber.

CONTROL PANEL OVERVIEW
4.1 Power Switch: The main power I/O (on/off) switch
controls all power to the unit and must be in the I/ON
position before any systems are operational.
4.2 Main Temperature Control: This control is marked
C and consists of the digital display and UP/DOWN arrow
pads for inputting set point temperatures and calibration.
4.3 Heating: This indicator is ON when the Temperature
Control has activated the heating elements to reach and
maintain set point.
4.4 Circuit Breaker / Fuse: This control, mounted on
the rear wall next to the power cord, provides protection for
the unit’s electrical circuitry against power fluctuations. The
circuit breaker, when tripped, must be reset by pushing in
the extended button for the unit to continue operation. The
fuse (on CE units in place of the circuit breaker) when
blown, must be replaced before the unit can continue
operation.
4.5 Vacuum Gauge: This component indicates the
chamber operating pressure in inches of mercury.
4.6 Vacuum: This adjustment valve allows opening and
closing of the piping system to an external vacuum pump or
system.
4.7 Vent: This adjustment valve controls the vacuum
release to return the chamber to atmospheric pressure.
4.8 Over Temperature Safety Control (OTP):
Located front left of the control panel, this is a
hydraulic thermostat that is wired between the Main
Temperature Controller and the heating element and
functions as an override control. If at any time the
Main Temperature Control fails in the ON position and
the temperature in the chamber rises above its set
point, the OTP is activated and maintains temperature
at its own set point.

PRECAUTIONS
NOTE: THIS IS NOT AN EXPOLOSION PROOF OVEN.
5.1 The bottom surface of the chamber should not be used as a work
surface.
5.2 Do not place or use explosive, combustible, or flammable materials in the oven.
5.3 Do not use sealed containers in the oven chamber.
5.4 Do not cut or remove the ground prong from the power cord or use a 2-prong
adapter plug.
5.5 Disconnect the unit from electrical power source before attempting to make any
repairs or component replacements.
5.6 If a mercury thermometer is used and breakage should occur, all spilled mercury
must be completely removed from the chamber.
5.7 This oven IS NOT suitable for use in Class I, II, or III locations as defined by
the National Electrical Code NFPA 70.
5.8 This oven is not intended, nor can it be used, as a patient, connected device.
Section

VACUUM OPERATION
6.1 IT IS IMPORTANT TO USE VACUUM TUBING FOR ALL THE VACUUM
HOOKUPS. OTHER TYPES OF TUBING MAY COLLAPSE AND PREVENT
EVACUATION.
6.2 A pump with a pumping capacity four times greater than the chamber volume is
recommended. For example, 1470 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 a 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 calibrated
from zero to 30 inches of Hg (762mm of Hg) with zero representing atmospheric
pressure. The oven can be evacuated to pressures as low as 10 microns.
A KF-25 Flange is provided at the back of the unit. This access can be used to
plumb the chamber to a larger, faster roughing pump or as a conduit for other
service applications. Any use of this flange requires the end user to assure the
attachment is vacuum tight.
6.5 These ovens are not intended for use as pressure chambers. Pressure above
atmospheric will blow by the door gasket and not allow build up of pressure.
6.6 Vacuum Release: To return the chamber to atmospheric pressure, open the
VENT valve slowly and allow the chamber to re-pressurize. The speed or re-
pressurizing can be controlled by how much the valve is opened.
6.7 Vacuum Gauge: To zero the gauge, simultaneously press the UP and DOWN
keys on the gauge until “000” is displayed.
Section

OPERATION
NOTE: Slight vapor or smoke may occur in the initial heat-up. This is the
dissipation of protective coatings that have been added 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 cord set, plug the
female end into the inlet of the unit and the male plug into the supply. Assure
that the units requiring a fuse have a fuse installed. This fuse may be at the inlet
or part of the cord set male plug.
7.2 Place a certified reference thermometer inside the chamber where it can be
easily viewed through a window. Vacuum down the chamber as described in
Section 6.0.
7.3 Set Main Temperature Control: To enter the desired set point temperature
press either the Up or Down arrow pad one time. The digital display will start to
blink from bright to dim. While blinking, the digital display can be changed by
pushing the Up or Down arrow pads until the desired set point is obtained. If no
arrow pads are pressed within five (5) seconds, the display will return to the
indicating mode. During normal operation the set point can be checked by using
this procedure and making no adjustments during the blinking mode. Allow
several hours for the temperature to stabilize.
7.4 Calibrating the Main Temperature: Calibrating the Main Temperature: It is
recommended that calibration is done once the unit is installed in its working
environment. The unit should be stable at set point for several hours and under
vacuum. Compare the reading of the reference thermometer with the digital
display. If there is an unacceptable difference, put the display into calibrate mode
by pressing both the UP and DOWN buttons at the same time until the decimal
points start to blink. While blinking, the display can be changed to match the
reference thermometer by pushing the UP or DOWN buttons until the display reads
the correct value. If no buttons are pushed for five (5) seconds the display will
revert back to reading the temperature in the chamber. Allow for the oven
temperature to stabilize again and recalibrate if necessary.
7.5 Setting the Over-Temperature Control: After the Main Temperatures are set and
adjusted, the Overtemperature Safety Control needs to be set. Do this by turning
the OTP Control Knob counterclockwise until the Overtemperature Light comes on
(this will blink in sequence with Heating Activated Light). Next, slowly turn the knob
clockwise until the light goes off, then turn the knob another 8 degrees
approximately. This should set the Overtemperature 1 degree above the Main
Temperature set point.

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 for your application. DO
NOT use chlorine based bleaches or abrasives as this 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 thorough, periodic cleaning is
strongly recommended.
B. When washing the gasket, handle carefully so as not to impair the positive
seal.
WARNING: Never clean the unit with alcohol of flammable cleaners with the unit
connected to the electrical supply. Always disconnect the unit from the electrical service
when cleaning and assure all volatile or flammable cleaners are evaporated and dry
before reattaching the unit to the power supply.
8.2 If the oven is to be shut down for storage or transporting, clean and described
above. Remove shelves and latch the door closed. Screw the leveling feet in on
the 1480 / 1490.
8.3 There is no maintenance required on the Temperature Controller or Temperature
Probe. If the oven fails to maintain temperature, see Troubleshooting before
calling for service.
