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 maybe performed bythe 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.
Installation of the FX28-2 requires hard wiring and should be performed by a qualified electrical technician. The
next higher circuit breaker value above the data plate amperage may be used provided the requirements in
article 422 of the National Electric Code are met (USA). The FX14-2 can be installed by the end user without a
technician.
3.1 Power Source: The electrical supply circuit to the oven must conform to all national and local
electrical codes. Consult the incubator’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 the unit and any 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. Leveling feet are supplied 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 level. If the unit must be moved, turn the leveling feet in all the way
to prevent damage.
3.5 Cleaning: The oven interior was cleaned at the factory, but not sterilized. Remove all interior
parts if assembled and clean with a disinfectant that is appropriate to your application. DO NOT
USE chlorine-based bleaches or abrasives as this will damage the stainless steel interior. DO
NOT USE spray cleaners that might leak through openings and cracks and get on electrical parts or
that maycontain 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 Burn 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 a minimum of one (1) hour until smoke
dissipates.

PRECAUTIONS
4.1 The bottom surface of the chamber should not be used as a work
surface.
4.2 These units have been designed with dampered vents 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 outgassed 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.
4.3Do 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 Be sure that the power supply is of the same voltage as specified.
4.7Disconnect the unit from the electrical source before proceeding to make any
electrical repairs or replacements.
4.8 If a mercury thermometer is used and breakage should occur, all spilled mercury
MUST be completely removed from the chamber before continuing operation.
4.9 This oven is NOT designed for use in Class I, II, or III locations as defined by the
National Electrical Code.
4.10 This oven is not intended, nor can it be used, as a patient connected device.

CONTROL PANEL OVERVIEW
5.1 Power Switch: The main power switch on the control panel (green lighted I/O) controls
all power to the unit and must be in the I/ON position before any systems are
operational. The switch will be lighted when in the I/ON position.
5.2 Timer Switch: The black I/O switch marked TIMER is located to the right of the power
switch. It controls the power to the time circuit. In the off position the oven heat is
controlled with no timed duration. In the on position the heat is controlled for a timed
interval and then the heat shuts off.
5.3 Main Temperature Control: This control is marked SET/TEMPERATURE and consists
of the digital display and UP/DOWN arrow pads for inputting set point temperatures and
calibration.
5.4 Overtemperature Safety Thermostat: This control is marked HIGH LIMIT and is
equipped with a graduated dial from 0-10. It is independent of the Main Controller and
guards against any failure which would allow the temperature to rise past the Main
Controllers set point. This allows continued operation of the oven until the problem can
be corrected or service can be arranged. It is not recommended that the unit be
operated for extended periods of time using only the Overtemperature Safety as the
controller as temperature uniformity will suffer.
5.5 OTP Light: This pilot lamp is marked OTP and is directly above the Overtemperature
Safety Thermostat. The light will come on when the Safety Thermostat has been
activated and taken control of the oven. Under normal operating conditions this pilot
lamp should never be on.
5.6 Timer Control: This control is marked SET/TIMER and consists of a digital display,
UP/DOWN arrow pads, a RESET “PUSH” pad, a START/STOP “PUSH” pad and a TIMER
ACTIVATED Light. This control provides the ability to set a timed heat interval, activate the
start-up of the timed heat cycle and shut down the timed heat cycle automatically.
5.7 Temperature Activated Light: This pilot lamp will be lit when the elements are receiving
power.

OPERATION
6.1 Connection to Power Supply: Assure that the electrical power supply is properly configured
and rated for the oven. The FX28-2 must be hard wired as stated in Section 3.0, Installation.
6.2 Push the POWER switch to the ON position. The digital temperature display will indicate a
temperature value. Turn the Overtemperature Safety Thermostat to its maximum position,
clockwise, by using a flat-head screwdriver.
6.3 Set Main Temperature Controller: Enter desired set point temperature. To enter set point mode
on the controller, press either the Up or Down arrow pad one time. The digital display will start to
blink, going from bright to dim. While blinking, the digital display is showing the set point. To
change the set point, use the Up and Down arrow pads. If the arrow pads are not pressed for five
(5) seconds, the display will stop blinking and will read the temperature of the unit. Note that the
High Limit Thermostat should be turned to its maximum position until the unit has stabilized at
desired set point temperature. Allow the oven at least 24 hours to stabilize.
6.4 Calibration: Temperature calibration is done once the unit is installed in its working
environment and has been stabile at set point for several hours. Place a certified reference
thermometer in the chamber by either placing it directly inside, or through the access tube at the
top left of the unit. Be certain the thermometer is not touching any shelving. Allow the
temperature to stabilize again until the thermometer reads a constant value for one hour.
Compare the digital display with the reference thermometer. If there is an unacceptable
difference, put the display into calibration mode by pressing both the Up and Down arrow pads at
the same time until the display begins to flash. While the numbers are flashing the display can be
calibrated by pressing the Up or Down arrow pads until the display reads the correct value. Allow
the oven temperature to stabilize again, and recalibrate if necessary.
NOTE: Temperature accuracy should be checked at least monthly or after the unit has been turned off
for an extended period of time.
6.5 Set Overtemperature Safety Thermostat: As mentioned in step 6.3, the Safety Thermostat
should be initially set to its maximum position to allow the unit to stabilize. Once the oven is
stabile at the desired set point, turn the Safety Thermostat counterclockwise with a flat-head
screwdriver until the OTP light turns ON. Next, turn the Thermostat clockwise just until the OTP
light turns OFF. Then turn the thermostat clockwise two (2) of the smallest divisions on its scale
past the point where the light went out. This sets the Safety Thermostat at a temperature
approximately 10C above the Main Temperature set point. Note that the Safety is in series with
the output from the control relay, and the OTP light will be blinking when the Main Temperature
Controller is calling for heat.
6.6 Set Timer Display: Turn the Timer switch to the ON position. The SET/TIMER display digits will
light with no lighted decimals showing (See Figure 2). Note that if during any of the following
steps, several seconds elapse with no arrow pad or RESET pad activity, the timer will default to
the present displayed setting and it will be necessary to restart all functions over again. The
values must be programmed in a consecutive manner with no delays between settings or the
default will occur.
A. Hour Function: Press and hold the RESET pad until the digits start blinking and
a blinking decimal point is between digits 2 and 3. In this mode, pressing the UP
or DOWN arrow pads increases or decreases the whole hour value from 0 to 99
(digits 1 and 2).
Section
6

9
B. Ten Minute Function: After the correct value for hours is set, push the RESET
pad again. The blinking decimal will now move one digit to the right between
digits 3 and 4. Pushing the UP or DOWN arrow pads will increase or decrease
the ten minute function allowing values between 0 to 5 to be set (digit 3).
C. One Minute Function: After the correct ten minute value is set, push the
RESET pad again. The blinking decimal point will now move one digit to the right
beyond digit 4 and be located at the extreme bottom right of the display. With the
display in this mode, pushing the UP or DOWN arrow pad will increase the one
minute function allowing the value of digit 4 to be adjusted between 0 and 9.
D. Activation: Pause until timer stops blinking. After all settings are made, push
the START/STOP button. The timer activated light will come on and after a brief
pause, the present oven temperature settings will be valid and heating will begin.
The oven will now heat up, control at the set point and stop after the timed period
on the SET/TIMER display has elapsed.
Note that when the system is in the timer mode, the heating circuit is de-energized until
the START/STOP button is pushed or the TIMER switch is turned Off. If a time change
or correction is necessary and the timer has already been activated, push the
START/STOP button to “STOP” the timer, and then repeat steps A through D above.
6.7 To set the timer so that timed operation will not start until the oven is stabile at set point, pre-heat
the oven in the normal mode until the desired temperature has stabilized. Turn on the TIMER
switch. Push and hold the RESET button until the timer display blinks, this is to be sure that the
pre-set timed value is correct. Press the START/STOP button to activate the timer.
