UNIT SPECIFICATIONS

SCHEMATICS

These units are Drosophila Specific incubators for professional, industrial or educational
use where the preparation or testing of materials is done at approximately atmospheric
pressure and no flammable, volatile or combustible materials are being heated. These
units are not intended for hazardous or household locations or use.

RECEIVING AND INSPECTION

Section

Your satisfaction and safety require a complete understanding of this unit. Read
the instructions thoroughly and be sure all operators are given adequate training
before attempting to put the unit in service. NOTE: This equipment must be used
only for its intended application; any alterations or modifications will void your
warranty.

1.1 Inspection: The carrier, when accepting shipment, also accepts responsibility for

safe delivery and is liable for loss or damage. On delivery, inspect for visible
exterior damage, note and describe on the freight bill any damage found and
enter your claim on the form supplied by the carrier.

1.2 Inspect for concealed loss or damage on the unit itself, both interior and exterior.
If necessary, the carrier will arrange for official inspection to substantiate your
claim.

1.3 Return Shipment: Save the shipping crate until you are sure all is well. If for
any reason you must return the unit, first contact your Customer Service
representative for authorization. Supply data plate information including model
number and serial number. For information on where to contact Customer
Service, please see the manual cover.

1.4 Accessories: Verify that all of the equipment indicated on the packing slip is
included with the unit. Carefully inspect all packaging before discarding. The
incubator is supplied with eight (8) shelves.

INSTALLATION

This unit should remain upright for 24 hours prior to operating to allow the oil in the
refrigeration compressor to settle.

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.

Operating Conditions: For optimum performance use your incubator at room temperatures
between 18 and 25 C, at no greater than 80% relative humidity. If you intend to operate the
unit in conditions outside of these limits contact customer service.

2.1 Power Source: Before connecting the unit to the power source, the electrical supply
circuit must conform to all national and local electrical codes. The power source must
match the cycle and ampere requirements as noted on the data plate located on the side
of the incubator. This unit is intended for 50/60 HZ application. VOLTAGE SHOULD
NOT VARY BY MORE THAN 10% FROM THE DATA PLATE RATING. A separate
circuit is recommended to prevent possible loss of product due to the overloading or
failure of other equipment on the same circuit.

2.2 Location: When selecting a site for the incubator, consider all conditions that may
affect performance, such as extreme heat from radiators, stoves, ovens, autoclaves, etc.
Avoid direct sun, fast moving air currents, heating and cooling ducts, and high traffic
areas. To ensure air circulation around the unit, allow a minimum of 20cm (8”) between
incubator and any walls or partitions that may obstruct free airflow.

2.3 Lifting and 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.

2.4 Leveling: The unit must sit level and solidly. Turn the leveling feet counterclockwise to
raise the level. If the unit must be moved, turn the leveling feet in all the way to prevent
bending and damage.

2.5 Cleaning: The unit chamber should be cleaned and disinfected prior to use. Remove all
of the interior parts, if assembled, and clean thoroughly, including all corners using a
suitable disinfectant that is appropriate to your application. DO NOT use spray cleaners
that might leak through openings and cracks and get on electrical components, or that
may contain solvents that will harm coatings. DO NOT use chlorine-based bleaches or
abrasives as they will damage the stainless steel interior. Regular periodic cleaning is
required. Special care should be taken when cleaning around sensing heads to prevent
damage.

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.

CONTROLS OVERVIEW

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: The Main Temperature Control is a Watlow P.I.D. (Proportional Integral
Derivative) dual output control. We strongly recommend that all operators read the included Watlow manual
to become familiar with the control. This unit is specifically designed for drosophila applications and the
actual chamber temperature will fluctuate above and below setpoint. This is normal.

4.3 HEATING Light: This pilot lamp is ON when the unit is heating up to set point and is blinking when
controlling temperature at set point.

4.4 Overtemperature Thermostat: This controller is marked SET OVERTEMPERATURE and is equipped with
an adjustment knob and a graduated dial from 0 to 10. Completely independent of the Main Temperature
Controller, the Overtemperature Thermostat guards against any failure of the Main Temperature Controller
which would allow temperature to rise past set point. If temperature rises to the Overtemperature set point,
the Overtemperature Thermostat takes control of the heating element and allows continued use of the
incubator until the problem can be resolved, or service can be arranged. It is not recommended that the unit
be allowed to operate for an extended period of time using only the Thermostat as temperature uniformity
will suffer.

4.5 OVER TEMP Light: This pilot light comes on when the Overtemperature Thermostat has been activated.
Under normal operating conditions this light should never come on.

4.6 Low Limit Thermostat: Located on the lower right rear of the unit, the Low Limit Thermostat keeps the unit

4.7 Defrost Switch: Used to defrost the unit if frost should form. It is an ON/OFF switch located on the top

4.8 Fuse: Located on the back, bottom near the cord inlet. adjacent t the defrost switch in place of the circuit

from freezing. It is factory set to activate at 1 and disengage at 3C and should not be adjusted.

breaker, the fuse offers protection against power source variations. Protection is in addition to the automatic
high temperature limit designed into the heating element. If the fuse is blown, the unit will shut down and the
cause should be determined and corrected before replacing the fuse.
