GENERAL
INSPECTION
When the equipment is received, all items should be carefully checked against the bill of lading to
ensure all crates and cartons have been received. All units should be inspected for concealed damage
by uncrating the units immediately. If any damage is found, it should be reported to the carrier at once,
and a claim should be filed with the carrier. This equipment has been inspected and tested in the
manufacturing facility and has been crated in accordance with transportation rules and guidelines.
Manufacturer is not responsible for freight loss or damage.
LOCATION
Allow a minimum four-inch clearance on the top, rear, and sides of the cabinet for proper ventilation.
The cabinet should also be leveled when it is placed in its permanent location. If two or more units are
positioned side to side, allow a minimum of 8 inches between cabinets. Choose a site free from rapidly
changing ambient temperature conditions. Radiators, air-conditioning outlets and other ventilating
outlets can affect the operation of the Refrigerated Incubator by a sudden in rush of air that is different
from standard operating conditions. Do not stack items on top of the unit. Vibration during shipping and
handling may loosen mechanical connections. Check all connections during installation. Check all
wiring, piping and fasteners.
CAUTION
Do not modify cabinet construction or associated equipment assemblies.
Do not remove labeling or information supplied with the unit.
INSTALLATION
For electrical requirements see data information and wiring unit diagram located in parts bag, inside of
the cabinet. Check the proposed external power outlet/supply to be used to ensure that the voltage,
phase and current carrying capacity of the circuit from the electrical panel correspond to the
requirements of the cabinet. The power cord of this Refrigerated Incubator is equipped with a threeprong (grounding) plug which mates to a standard three-prong (grounding) receptacle. NEVER
extension cord to wire any unit. Refer to the serial tag (nameplate data) for all pertinent electrical
information.
power cord. Do not use a two-prong adapter plug.
Observe all Warning Labels. Disconnect power supply(s) to eliminate injury from electrical shock
or moving parts when servicing equipment.
The Refrigerated Incubator should not be operated in an environment where the ambient
temperature exceeds 90°F (32.2°C) as the compressor thermal overload will be tripped and will
result in a wide band control cycle of approximately ±4°C. Such cycling should not be
interpreted as a malfunction of the electronic controls.
When loading the Refrigerated Incubator, a space of ½” minimum should be allowed between adjacent
items to allow for maximum air circulation. Temperature uniformity will be adversely affected if air
circulation is obstructed.
Excessive frost buildup on the evaporator coil located on the rear cabinet wall will also affect
temperature uniformity.
WARNING- SAFETY PRECAUTIONS
Do not, under any circumstances, remove the third (ground) prong from the
