This incubator is intended for use indoors, at room temperatures between 5C and 60C (41F and
140F), at no greater than 80% Relative Humidity at 25C (77F). Allow a minimum of 2 inches
(5cm) between the rear and sides of the incubator and walls or partitions.
Operating the unit outside of these conditions may adversely affect the temperature range
and stability.
For conditions outside of those listed above, please contact your distributor or Sheldon Sales to
explore other incubator options suited to your laboratory or production environment.
LOCATION
When selecting a location to install the incubator, consider all environmental conditions that can
affect unit’s effective temperature range, uniformity, and stability. For example:
Ovens, autoclaves, and any device that produces significant radiant heat
Heating and cooling ducts, or other sources of fast moving air currents
High-traffic areas
Direct sunlight
LIFTING AND HANDLING
The incubator is heavy and bulky. Care should be taken to use appropriate lifting assistance
devices that are sufficiently rated for these loads. Follow these guidelines when lifting and handling
the incubator.

INSTALLATION (CONTINUED)
PLATFORM INSTALLATION
The SSI2 and SSI2-2 come with a flat non-stick platform for low speed operation with common
vessels, including trays and dishes. To install an optional platform the user must:
Unscrew the four aluminum, platform thumb screws from the corners of the internal
platform and remove the green rubber mat.
Clean any dirt or debris from the metal base-platform and apply the desired optional
platform so that the four corner holes are aligned.
Screw in the four aluminum, platform thumb screws tightly by hand.
POWER SOURCE
Always position the unit so the end-user has access to the power plug.
Check the data plate for voltage and ampere requirements before making a connection. If the
requirements match your power source, plug the power cord into an earth grounded outlet.
Supplied voltage must not vary more than 10% from the data plate rating. Damage to the
incubator may result if supplied voltage varies more than 10%.
These incubators are intended for a 50/60 Hz application. Use a separate circuit to prevent loss of
product due to overloading or circuit failure.
Note: Electrical supply to the incubator must conform to all national and local electrical codes.
