GLYCERIN WELL ASSEMBLY
3 7/10 Rev. C 131783
Important: For accurate product temperature reading, the
product-sensing bulb must be immersed in glycerin solution
contained in the provided well.
One glycerin well is furnished with each model. The
purpose of the glycerin is to simulate the product stored in
the Incubator. The glycerin temperature reflects the
product's temperature during normal operation.
Figure 1
After the unit is put into operation, check to make sure that
the temperature indicating or alarm sensing bulb is
positioned inside the glycerin well as far as possible without
touching the well itself.
OPERATION
The Large Capacity Incubator is designed for an operating range of 5°C above room ambient to
70°C and is intended for indoor use only. A transverse blower optimizes airflow and ensures tight
temperature uniformity.
These units employ a programmable controller to control the temperature and CO
2
option. The
controller is located on the facade of the unit. Please see the separate instructions, part number
113635, on the operation of the controller used in the Large Capacity Incubator.
The Incubator utilizes an electrically operated heater to warm the cabinet. The programmable
control is factory set with a cutout temperature of 70°C (158°F) to prevent the cabinet from
exceeding its design limitations.
NOTE: The cabinet is equipped with two switches located on the façade. One is the main power
ON/OFF switch for the unit. The other is a three-position switch for the battery-powered alarm. The
alarm switch is placed in the middle, or OFF position, for shipment. When the Large Capacity
Incubator is put into operation, the top of the switch should be pushed in to the ON position. With
the switch in the ON position, the battery will sound the alarm if the main power to the cabinet is
interrupted. The switch flipped to the bottom position is used to test the battery. This test must be
done with power uninterrupted to the cabinet. The alarm will sound if the battery is good. This test
should be done periodically. The battery is located on the control box that is on top of the unit
behind the façade.
