Unpacking and Inspection

At delivery, examine the exterior for physical damage while the
carrier's representative is present. If exterior damage is present,
carefully unpack and inspect the unit and all accessories for
damage.
If there is no exterior damage, unpack and inspect the equipment
within five days of delivery. If you find any damage, keep the
packing materials and immediately report the damage to the
carrier. Do not return goods without written authorization.
When submitting a claim for shipping damage, request that the
carrier inspect the shipping container and equipment.

Installation

4.1 Location

Install the unit in a level area free from vibration with a minimum
of 6 inches of space on the sides and rear and 12 inches at the top.
Do not position the equipment in direct sunlight or near heating
diffusers, radiators, or other sources of heat. The ambient
temperature range at the location must be 59 to 90°F
(15 to 32°C).

4.2 Wiring

CAUTION!
Connect the equipment to a separate,
dedicated, power source with the correct voltage.
Power fluctuations or incorrect voltage can result in
severe damage to the equipment.
DANGER!
For personal safety and trouble-free
operation, this unit must be properly grounded before
it is used. Failure to ground the equipment may cause
personal injury or damage to the equipment. Always
conform to the National Electrical Code and local
codes. Do not connect unit to already overloaded
power lines.
Always connect the equipment to a dedicated (separate) circuit.
Electrical codes require fuse or circuit breaker protection for
branch circuit conductors. Use time delay fuses for #12 AWG
circuits.
For all blood bank models, the wiring diagram is attached to the
back of the cabinet.

4.3 Leveling

The unit must be level. Rotate the leveling screws, located under
the front corners of the unit, until the unit is level. If the floor is
seriously out of level, you may need to shim the corners with thin
sheets of metal.
Use thin sheets of metal to level units equipped with
Note:
optional casters.

4.4 Door Operation

Standard glass doors for models larger than the undercounter
model stay open if opened 90 degrees. Door spring tension
cannot be adjusted.
If the self-closing doors do not work properly, make sure the unit
is level.
4.4.1 Adjustable Hinged Glass Doors (Undercounter
Models Only)
On Undercounter models with hinged glass doors, you can use a
regular screwdriver to adjust spring tension and center each door
on its frame. The adjustment screws ("torque" for tension and
"sag" for door placement) are located on the bottom hinge
bracket (shown below in Figure 1).
Hinged glass doors can be propped open with metal braces at the
bottom hinges. Open the door 90 degrees or until you feel some
resistance. Push the door open past the resistance and the metal
braces engage. To close the door, push it toward the unit (past the
resistance).

CAUTION!
Do not overtighten the tension as

WARNING!
Disconnect equipment from main power
before attempting any maintenance to equipment or its
controls.
