Section 1 - Receiving
1.1 Preliminary Inspection
This item was thoroughly inspected and carefully packed prior to shipment and all necessary
precautions were taken to ensure safe arrival of the merchandise at its destination. Immediately
upon receipt, before the unit is moved from the receiving area, carefully examine the shipment for
loss or damage. Unpack the shipment and inspect both interior and exterior for any in-transit
damage.
1.2 Visible Loss or Damage
If any loss or damage is discovered, note any discrepancies on the delivery receipt. Failure to
adequately describe such evidence of loss or damage may result in the carrier refusing to honor a
damage claim. Immediately call the delivering carrier and request that their representative perform
an inspection. Do not discard any of the packing material and under no circumstances move the
shipment from the receiving area.
1.3 Responsibility for Shipping Damage
For products shipped F.O.B. Marietta, Ohio, the responsibility of Thermo Forma ends when the
merchandise is loaded onto the carrier's vehicle.
On F.O.B. Destination shipments, Thermo Forma's and the carrier's responsibility ends when
your Receiving Department personnel sign a free and clear delivery receipt.
Whenever possible, Thermo Forma will assist in settling claims for loss or in-transit damage.

Model 3980 and 3986 Incubators _________________________________Installation/Start-Up
2-1
Section 2 - Installation and Start-Up
2.1 Location
Locate the unit on a firm, level surface in an area of minimum ambient temperature
fluctuation. A minimum of 12 inches clearance is required at the top of the incubator
and a minimum of three inches clearance is required at the rear of the incubator to
facilitate adequate air flow around the refrigeration system.
2.2 Connecting the Water (Humidity) System
Do not attempt to operate the humidity system without filling it with
water. The humidification heater will overheat, and the overtemp
safety thermostat will shut the humidification system down.
The humidity reservoir will require approximately one quart (.946 liter) of water on the
initial filling. To ensure continuous satisfactory operation of the incubator, only distilled
water should be used in the humidity system. Purity of the distilled water used in the
incubator humidifier reservoir must be within the 50K Ohm to 1 M Ohm range to protect
and prolong the life of the stainless steel unit.
Important:
Use of tap water, or distilled water outside the specified range,
will decrease the operating life of the unit and will void warranty.
The water inlet is the 1/8" NPT connection located on the rear top left corner of the
incubator. Water inlet pressure at the unit should be from 15 to 40 PSI. A manual shut-off
valve should be installed between the main water supply and the incubator.
To prevent mineral buildup on heater coils and
humidity generator walls, it may be necessary to clean the
humidity generator and immersion heaters with a non-
metallic abrasive pad and flush thoroughly every two or three
months. Refer to Section 5.8, Cleaning and Adjusting the
Humidity Steam Generator.
