Installation

The Incubator is fastened to the base skid and it is usually the best procedure to leave the skid attached
until the Incubator is located in its approximate position to facilitate ease in handling. The base skid can
then be removed by removing the four bolts holding the cabinet to the skid. Examine the Incubator
carefully. INSPECT both the exterior and the interior for any transit damage before discarding the
shipping crate.
7.1

Location

In locating the Incubator, consider all possible conditions that might affect its performance as well as
laboratory procedures for its intended purpose. Do not locate near heating or cooling ducts, or next to
equipment that generates heat (steam radiators, stoves, ovens, autoclaves, etc). Avoid direct sunrays
and rapidly moving air currents. These conditions adversely affect the even heat dissipation required
from the exterior surfaces of the Incubator and will cause the temperature variation in the chamber to
exceed specifications as stated in section 3.2. Since the Incubator needs even heat dissipation on all
surfaces in order to maintain an internal temperature variation of less than 0.2 degrees C, a minimum of 2
inches (50mm) must be allowed between the rear and sides of the Incubator and any walls, partitions or
obstructions to facilitate adequate convection of air around the unit. Confirm clearance with a tape
measure if needed. Adjust the Incubator location accordingly. In addition, since the Incubator is cord
connected, the cord must be readily accessible for disconnection if necessary. For maintenance/service
purposes, the control center electronics should remain accessible.
Place Incubators 10" apart when placed side-by-side to enable running the heated Decon Cycle while
surrounding Incubators are in normal mode.

Leveling

Prior to use the incubator should be leveled using a bubble level on a middle shelf in the chamber. The
Incubator should have all 4 feet firmly on the bench or floor. Level from side to side and front to back.
Leveling feet are provided for this purpose, factory installed into the base of the Incubator. By turning the
adjustable leveling feet counter-clockwise, raises the Incubator. The leveling feet height should be a
minimum of 1/4 inch (6mm) below the base. IT IS IMPORTANT THAT THE OUTER CABINET BE
OFF THE FLOOR BY AT LEAST 1/4-INCH (6MM) TO ASSURE CABINET AIR FLOW
RELIEF. Confirm with a tape measure if needed.
