INSTALLATION

Section

3

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 circumstance 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
these limits.

3.1 Power Requirements: The unit power requirements are listed on the units data plate
located on the right front side of the oven. Make sure your power supply matches that
shown on the data plate. VOLTAGE SHOULD NOT VARY MORE THAN 10% FROM THE
DATAPLATE RATING. These units are intended for 50/60HZ application. A separate circuit
is recommended to preclude loss of product due to overloading or circuit failure.

3.2 Location: Select a site for the oven which is free from extreme heat, cold or excessive air
movement such as areas near steam radiators, stoves, other ovens, autoclaves, direct sun,
heating and cooling ducts, etc. Avoid high traffic areas which may reduce the accessibility to
the oven. Allow at least 30 cm of space between the oven and surrounding 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 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. Leveling feet (supplied) are to be installed in
the holes at the base of the oven. Turn them counterclockwise to raise the level and
clockwise to lower the level. If the unit must be moved, turn the leveling feet in all the way to
prevent damage.

3.5 Cleaning: The oven's interior was cleaned at the factory, but not sterilized. Remove all
interior parts if assembled and clean the inside of the chamber thoroughly with a disinfectant
that is suitable for your application. Make sure to rinse the cleaned surface with a damp
cloth, using water only, and dry the surfaces with a clean cloth. DO NOT USE chlorine­based bleaches or abrasives as they will damage the stainless steel surface. 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 Burning In: It is recommended that the unit go through a “burning in” process prior to
operation. This is to eliminate the smoking of protective coatings on the element. Read
sections 4, 5 and 6 carefully to understand operating requirements. To burn in turn the
Overtemperature Safety to maximum and set the digital display to 200. Run for a minimum
of one hour under ventilation until smoke dissipates.

PRECAUTIONS

Section

4

4.1 The bottom surface of the chamber should not be used as a work
surface.

4.2 This unit has been designed with a dampered vent from the chamber. In

order to work effectively and safely, some precautions will need to be taken
by the operator.

A. In most applications, the exhaust damper will need to be opened

during drying or degassing for best results.

B. THIS OVEN IS NOT DESIGNED TO HANDLE COMBUSTIBLE

GASSES AND IS NOT AN EXPLOSION PROOF UNIT. Do not
place explosive, combustible, or flammable materials into the
chamber.

C. Some of the out gassed by products may be hazardous or

unpleasant to operating personnel. If this is the case, the exhausts
should be positively ventilated to the outside and dealt with
according to local regulations. Your dealer can provide you with a
power exhaust which greatly helps under these applications.

4.3 Do not operate near noxious fumes.

4.4 Do not place sealed or filled containers in the oven chamber.

4.5 Do not cut or remove the ground prong from the power cord.

4.6 Do not use a 2-prong adapter plug.

4.7 Be sure that the power supply is of the same voltage as specified.

4.8 Disconnect the unit from its electrical source before proceeding to make

any electrical repairs or replacements.

4.9 If a mercury thermometer is used for calibration and breakage should occur,
all spilled mercury MUST be completely removed from the chamber before
continuing operation.

4.10 This oven is NOT designed for the use in Class I, II, or III locations as
defined by the National Electric Code.

4.11 This oven is not intended, nor can it be used, as a patient connected
