UNPACKING and INSPECTION

NOTE: If damage is observed, keep the shipment intact
(including the carton and all packing material) and file a claim
with the final carrier.

INSTALLATION

The Low Temperature Incubator should be installed on a level,
stable floor. Use the adjustable feet to level the incubator.
Locate the unit so that there is at least 3 inches of clearance
around the sides, top and back to ensure sufficient ventilation.
Note: When cooling is enabled, heat is dissipated on sides of
unit resulting in side temperatures of 35 to 55°C. To prevent
heat build up within the unit, do not install it where it will be
exposed to strong sunlight, nor near radiators, furnaces, or
other sources of heat. Do not install the incubator where
flammable or corrosive atmospheres may exist. The Low
Temperature Incubator is not to be used out-of-doors or where
excessive moisture or contamination could cause degrading of
mechanical or electrical components.
1. Unbolt and remove the wooden slats underneath unit.
2. Remove all protective tape from doors and shelves.
3. Clean interior and exterior with warm soap and water.
Shipping tape residue can be removed using isopropyl alcohol.
4. Uncoil line cord from rear of unit. Connect the plug to a
power outlet that complies with the electrical requirements
specified on the unit's label and with proper safety ground
connection. If line cord replacement is necessary, use CSA
types: SJ, SJO or SJT, 16 GA, 3 cond. or equivalent.
