spring tension cannot be adjusted.
If the self-closing door does not work properly, make sure the unit is level.
7.9.1 Door Seal
7.10 Remote Alarm
(Optional)
CAUTION: Door seal integrity is critical for refrigerator performance. A
loose fitting gasket allows moist air to be drawn into the cabinet, resulting in
quicker frost buildup on the evaporator coil, longer running time, poor
temperature maintenance, and increased operation cost.
All units have factory-installed local alarm contacts that can be used for remote
alarm systems. The maximum distance between a refrigerator and a remote alarm
depends on the wire gauge used. Refer

8.1 Initial Startup
To start up the refrigerator, complete the following steps:
1. Verify that the sensor probe(s) have been installed in the bottle(s) as
described in Section 7.8.
2. Ensure the double pole circuit breaker switch located next to the power
inlet is in “ON” position (i.e. “I” position).
3. Insert the silver colored key in the switch and turn to the Power On
position. The display will show the actual cabinet temperature and the
compressor and evaporator should start within 10 minutes.
4. Allow the unit to reach operating temperature before loading it with any
product. To stabilize the temperature profile, a 24-hour waiting period
is recommended.
5. If you desire to enable the alarms, turn the three position key switch one
turn further clockwise to the Alarm On position. To avoid nuisance
alarms, wait until the unit has pulled down to the desired operating
temperature (4°C default).
6. If you have a remote alarm, hook it up at this point (refer Section 7.10).
7. If desired, lock the cabinet door using the gold colored key. Place
duplicate key copies in a safe place.
8.2 Product Loading and
Unloading Guidelines
All controls should now be fully operational, the alarm active (if enabled),
and all visual indicators active.
When loading your blood bank refrigerator, take care to observe the following
guidelines:
•Never load the blood bank beyond capacity. The number of 450ml bags
that are recommended for your unit are 385.
•Distribute the load as evenly as possible. Temperature uniformity
depends on air circulation, which could be impeded if drawers are
overfilled, particularly at the top of the cabinet.
•For critical applications such as blood storage, be sure that the alarm
systems are working and active before you load any product.
•Stacking the load higher than 8 in (20.3 cm) from the bottom of the
drawer may affect unit performance or impede operation of the drawers.
•For initial product loading and after removing the drawers for cleaning,
be sure to load the unit from the bottom drawer up to ensure the
drawers are seated properly.

12.4 Automatic Defrost
12.5 Gasket
Maintenance
The defrosting process on all models is primarily accomplished by air circulated
during off-cycle periods. This heat-free process ensures that the temperature is
not affected by the defrost cycle. The default defrost cycle runs once per hour and
terminates once a preset evaporator temperature or timer criteria is reached.
Defrost water is collected in a pan in the rear of the unit and evaporated using
system heat. No maintenance is required.
Periodically check the gaskets around the door for punctures or tears. Leaks are
indicated by condensation or frost which form at the point of gasket failure.
Make sure that the cabinet is level (refer to
Keep the door gaskets clean and frost free by wiping gently with a soft cloth.
To check the door seal, complete the following steps:
1. Open the door.
2. Insert a strip of paper (a couple of inches wide) between the door gasket
and the cabinet flange and close the door.
3. Slowly pull the paper strip from the outside. You should feel some
resistance.
