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.
Power : The power source must match the voltage, cycle, phase and ampere
requirements listed on the data plate (located just above the power cord on
the back side of the oven). The unit is intended for 50/60 HZ application.
Make sure your power supply matches that shown on the data plate. VOLTAGE
SHOULD NOT VARY MORE THAN 10% FROM THE DATA PLATE RATING. A separate circuit
is recommended to preclude loss of product due to overloading or circuit
failure. Note that the electrical supply to the unit must conform to all
national and local electrical codes.
Location : When selecting a site for the oven, consider conditions that
may affect performance, such as heat or cold from air vents, fast moving air
currents, other ovens, autoclaves, direct sun, etc. Avoid high traffic areas
that may reduce accessibility to the oven and allow at least 20cm between the
unit and surrounding walls or partitions that might obstruct free airflow.
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 and 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.
Leveling: The unit must sit level and solidly. The oven is equipped with
non-adjustable rubber feet to raise it off the counter and prevent sliding;
however, the counter must be level to provide optimum working and safety
conditions.
Cleaning: The oven was cleaned at the factory, but not sterilized. Remove
all interior parts, including shelves and shelf clips. If assembled and clean
the inside of the chamber thoroughly with a disinfectant that is appropriate
for your application. DO NOT USE chlorine-based bleaches or abrasive cleaners,
as they will damage the ovens interior surfaces. DO NOT USE spray cleaners
that might leak through openings and cracks and get on electrical parts or
that may contain solvents that willharm coatings. A regular 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 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.
Shelves : Place shelves in the chamber at desired position. See Figure 1.
CONTROL PANEL OVERVIEW
Power Switch: The main power I/O (on/off) switch controls all power to
the oven. It must be in the I or ON position before any systems are
operational.
Main Temperature Controller: Marked SET TEMPERATURE, this control is
equipped with an adjustment knob and a graduated dial. The graduated dial is
marked with 10 major increments. The increments can be used as index points
for setting and returning to set point temperatures.
HEATING light: This green pilot light is marked HEAT ACTIVATED and
indicates when the element has been activated and the oven is heating. When
set point is reached the pilot light will cycle on and off as the elements
maintain the temperature selected.
Over Temperature Thermostat: Marked SET OVERTEMPERATURE, this control is
completely independent of the Main Temperature control and is equipped with an
adjustment knob that requires a flat-edged tool when making adjustments to
eliminate accidental changes. It provides safety temperature protection for
the oven. If for any reason the oven temperature rises above the Main
Temperature control’s set point, the Over Temperature Thermostat will limit
the rise to approximately 10°C above the set point selected.
Over Temperature light : This red pilot light is marked OVERTEMPERATURE
ACTIVATED and is on when the Over Temperature Thermostat has been activated
and taken control of the elements. Under normal operating conditions this
pilot light should never be on.
PRECAUTIONS
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.
The bottom surface of the chamber should not be used as a work area.
In most applications, the exhaust damper will need to be open during drying or
degassing for best results.
THIS OVEN IS NOT AN EXPLOSION PROOF OVEN AND IS NOT DESIGNED TO HANDLE
COMBUSTIBLE GASSES. Do not place explosive, combustible or flammable materials
into the chamber.
Some of the out-gassed byproducts 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 that greatly helps under these applications.
Do not place sealed or filled containers in the oven chamber.
This oven is NOT designed for use in Class I, II, or III locations as defined
by the National Electrical Code.
This oven is not intended, nor can it be used, as a patient connected device.
OPERATION
Power Supply: The power supply must be properly grounded (earthed) and
correctly sized to match the unit data plate rating. The supply voltage must
match the data plate voltage within 10%. If supplied with a detachable cord
set, plug the female end into the inlet on the unit and the male plug into the
supply. Assure that units requiring a fuse have a fuse installed.
Push the power switch to the ON position and turn the Over Temperature
Thermostat to its maximum position, clockwise so it will not interrupt the
setting of the Main Temperature control.
Place the reference thermometer through the exhaust port on top of the unit; a
clip is provided with your accessory package. See Figure 3 on the following
page.
Setting Main Temperature : The operating range for this oven is ambient
room temperature + 5C to 200C. To set the Main Temperature Controller turn
the knob to the desired oven temperature, using the graduated dial as a
reference guide. Allow one hour for the temperature to stabilize. Using the
reference thermometer, verify the oven temperature; if it is not at the
desired value, turn the control knob up or down as needed. Allow the
temperature to re-stabilize, continuing the process until the exact desired
temperature is achieved.
Note: Slight vapor or smoke may occur in the initial heat-up. This is a
normal occurrence when the oven is first brought up to temperature and
protective coatings on the element become hot.
Setting Over Temperature: As stated in earlier, the Thermostat should be
set to its maximum position. Now turn the control knob counterclockwise just
until the OVERTEMPERATURE ACTIVATED light comes on. Next, slowly turn the
control knob clockwise just until the light goes off. Then turn the control
knob clockwise two (2) minor scale divisions past the point where the light
went out. The Over Temperature Thermostat should now be set at approximately
°C above the Main Temperature set point. Note that it is not recommended that
the unit be allowed to operate using the Over Temperature Thermostat as the
temperature controller for an extended period of time. See the Troubleshooting
section if the Thermostat is activated
PLACEMENT OF NEW THERMOMETER CLIP
MAINTENANCE
Note: Prior to any maintenance or service on this unit, disconnect service
cord from the power supply.
Cleaning: Clean the oven interior on a regular basis. When washing
interior of unit, handle gasket carefully so as not to impair the positive
seal. Clean the inside of the chamber thoroughly with a disinfectant that is
appropriate for your application. Make sure to rinse the cleaned surface with
a damp cloth. DO NOT USE chlorine-based bleaches or abrasive cleaners, as they
will damage the oven chamber. 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 coatings.
WARNING: Never clean the unit with alcohol or 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.
Storage: If the unit is to be shut down for an extended period of time,
wipe the chamber clean and let dry before closing door to eliminate
possibility of contamination. If the unit is to be transported, remove
shelving and trays, clasp the door shut and disconnect the power supply.
Please refer to Section 3.3, Lifting / Handling for further direction.
No maintenance is required on the electrical components. If oven fails to
operate as specified please review Troubleshooting prior to calling customer
service.
