INSTALLATION

Section

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 incubator must conform to all national and
local electrical codes. Consult the incubator’s serial data plate for the voltage 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 incubator, 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 20 cm between the unit rear and sides 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 of the unit. Turn the leveling feet counterclockwise to raise level.
Adjust the foot at each corner until the unit stands level and solid without rocking. If the unit must
be moved, turn the leveling feet in all the way to prevent bending and damage.

3.5 Cleaning: The incubator interior was cleaned at the factory, but not sterilized. Remove all
interior parts, including shelves and shelf clips 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 may contain solvents that will harm the coatings. A thorough
periodic cleaning is strongly 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 of flammable cleaners are evaporated and dry before reattaching the unit to the
power supply.

CONTROL PANEL OVERVIEW

Section

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: Marked SET TEMP, the Main Temperature Control
consists of the digital display and UP/DOWN arrow pads for inputting set point
temperatures and calibration.

4.3 Over Temperature Protection (OTP) Safety Thermostat: This thermostat,
labeled SAFETY TEMP, is completely independent of the Main Temperature
Controller. The OTP guards against any failure of the Main Temperature
Controller that would allow the temperature to rise past the set point. If
temperature rises to the Safety set point, the Safety takes control of the heating
element and allows continued use of the incubator until the problem can be
resolved or service can be arranged. The control is adjusted using a screwdriver
or a small coin. If the alarm sounds, hit the MUTE button.

4.4 Shaker Switch: Located directly under the SET RPM display and UP/DOWN
buttons, this switch engages the oscillation mode of the incubator. To enable
oscillation, this switch must be in the I/ON position. This switch does not have to
be ON to adjust the oscillation set point.

4.5 Shaker Controller: This control is labeled SET RPM and consists of the
UP/DOWN arrow pads and a digital display that shows oscillations per minute.
This control is adjustable from 30 to 400 RPM.

6

OPERATION

Section

5.1 Check the power source against the unit’s data plate. They must be within 10%.

5.2 Plug service cord into the grounded electrical outlet.

5.3 Push the POWER switch to the I/ON position, and turn the SAFETY TEMP thermostat to its

maximum clockwise position.

5.4 Installing Sample Tray: The sample tray is positioned by enclosing all corners of the shaking
mechanism within the lips of the sample tray. This can be done easily by positioning the front two
corners then setting the rest of the tray down. The tray should be shaken by its handles after
placement to confirm that it is firmly in place. Press the locking levers fully into the down/locked
position.

5.5 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 incubator at least 24 hours to stabilize.

5.6 Calibration: It is recommended that 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 placing it directly inside. 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 two outside decimal points begin to flash. While the
decimal points are flashing the display can be calibrated by pressing the Up or Down arrow pads
until the display reads the correct value. Allow the incubator temperature to stabilize again, and
recalibrate if necessary.

5.7 Set Over Temperature Protection Safety Thermostat: Once the incubator is stabile at the
desired set point, turn the SAFETY TEMP thermostat counterclockwise just until the Safety
indicator light turns on. Next, turn the SAFETY TEMP thermostat clockwise just until the safety
indicator light turns off. Then continue to turn clockwise an additional two small divisions on its
scale past the point where the indicator light went out. This will set the SAFETY TEMP
thermostat at approximately 1C above the Main Temperature set point.

5.8 Set Oscillation Control: Enter set point mode by pushing and releasing either the UP or Down
arrow pad one time. The display will start to blink on and off showing the RPM set point. Pushing
the UP or DOWN arrow pad will increase or decrease the RPM set point in increments of 1 RPM.
The range for this set point is 30 – 400 RPM. If the arrow pads are not pressed for five (5)
seconds the display will stop blinking and revert to displaying the actual RPM.

Note that for shaker controls to work as described, the door must be completely closed.
There is a door switch that will stop the shaker if the door is opened.

7

CAUTION

5.9 Using The Timer

Using the incubator’s timer, you can run the shaker platform at a preset RPM for a preset

time. The timer can be set at intervals of one (1) minute up to a maximum of a 999 (16 hours
39 minutes).

Upon completion of the timing cycle, the TIMER alarm LIGHT will turn ON and an alarm will
sound.

You can interrupt the timer if you need to access the shaking platform before the timer
completes.

5.10 TO START A TIMED SHAKING PROCESS

Turn the TIMER switch to the ON (I) position.
Press the set timer up or down arrow key once. The display starts to blink off and on and

shows the current set time. Press the up or down arrow to select the desired time.
Approximately five seconds after you release the Up or Down arrow keys, the display stops

flashing and the timing interval begins.

5.11 To Interrupt A Timed Shaking Process

Turn the TIMER switch and the RPM switch to the OFF (O) position.

Wait for the mechanism to come to a complete stop before entering the chamber.

5.12 To Restart An Interrupted Timed Shaking Process

Turn the RPM and TIMER switch to the ON (I) position.

TROUBLESHOOTING

TEMPERATURE

Temperature too high-display and
reference thermometer don’t match

1/ Controller set too high-see section 5.5.
2/ Controller failed on – call Customer Service.
3/ Wiring error – call Customer Service.

Display reads "HI"

Probe is defective, unplugged, or the wire is broken – trace wire from
display to probe; move wire and watch display to see intermittent
problems.

Chamber temperature spikes over set
point and then settles to set point

Recalibrate – see section 5.6.

Temperature too low-display and
reference thermometer don’t match

1/ OTP set too low – turn OTP fully clockwise.
2/ Controller set too low – see Section 5.5.
3/ Unit not recovered from door opening – wait for display to stop
changing.
4/ Unit not recovered from power failure or being turned off – incubators
will need 24 hours to warm up and stabilize.
5/ Element failure – see if heating light is on; compare current draw to
data plate.
6/ controller failure – confirm with front panel lights that controller is
calling for heat
7/ OTP failure – confirm with front panel lights that OTP is operating
correctly.
8/ Loose connection – check shadow box for loose connections.

Display reads "LO"

Sensor is plugged in backwards – reverse sensor wires to controller.

Unit will not heat over a temperature that
is below set point

1/ Confirm that amperage and voltage match data plate
2/ Confirm that set point is set high enough –turn OTP all the way
clockwise and see if heating light or safety light comes on.
3/ Check calibration – using independent thermometer, follow
instructions in section 5.6.

Unit will not heat up at all

1/ Verify that controller is asking for heat by looking for controller light –
if pilot light is not on continuously during initial start up, there is a
problem with the controller.
2/ Check amperage – amperage should be virtually at maximum rated
(data plate) amperage.
3/ Do all controller functions work?
4/ Is the OTP set high enough? – for diagnostics, should be fully
clockwise with the pilot light never on.
5/ Has the fuse/circuit breaker blown?

Indicated chamber temperature unstable

1/ ±0.1 may be normal.
2/ Is ambient radically changing – either door opening or room airflow
from heaters or air conditioning ? – stabilize ambient conditions.

Section

10

3/ Sensor miss-located, damaged or wires may be damaged - check
mounts for control and OTP sensors, then trace wires or tubing between
sensors and controls.
4/ Calibration sensitivity – call Customer Service.
5/ OTP set too low – be sure that its setting is more than 5 degrees over
desired set point. Check if pilot light is on continuously; turn controller
knob completely clockwise to see if problem solved, then follow
instructions in section 5.6 for correct setting.
6/ Electrical noise – remove nearby sources of RFI including motors,
arcing relays or radio transmitters.
7/ Bad connection on temperature sensor or faulty sensor – check
connectors for continuity and mechanical soundness while watching
display for erratic behavior; check sensor and wiring for mechanical
damage.
8/ Bad connections – check connectors for mechanical soundness and
look for corrosion around terminals or signs of arcing or other visible
deterioration.
