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 circumstance this unit is intended for use indoors, at room temperatures between 5 and 40
C, at no greater than 80% Relative Humidity ( at 25C ) 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
3.5 Cleaning: The oven's interior was cleaned at the factory, but not sterilized. Remove all interior parts
3.6 Burning In: It is recommended that the unit go through a “burning in” process prior to operation.
at the base of the oven. Turn them counterclockwise to raise the level and clockwise to lower the

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 chlorine-based 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.
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.
