7.3 Leveling
CAUTION: An unlevel unit may result in instability and performance
issues for the doors and drawers.
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.
Note Use thin sheets of metal to level units equipped with optional casters.
7.4 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.
7.4.1 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).

Installation
Thermo Scientific Recvo Blood Bank Refrigerators Installation and Operation 11
CAUTION: Do not overtighten the tension as damage to the equipment
can result.
WARNING: Disconnect equipment from main power before attempting
any maintenance to equipment or its controls.
7.5 Door Seal
CAUTION: Keep hands and body parts clear of closing doors. The moving
parts create a potential pinch point.
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.
4. Repeat this test at 4-inch intervals around the door. If the door does
not seal properly, you need to either replace the gasket, or adjust the
door (see the previous page).
Note Door seal integrity is critical for blood bank refrigerators. 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.
The door seals on 12 ft³ models can be adjusted. To correct a faulty seal on
these units, complete the following steps:
1. Open the door completely.
2. Remove the hinge pin cover to expose the door mounting screws. This
cover pops off.
3. Loosen the screws and move the door side of the hinge to decrease the
clearance between the gasket and the cabin.
4. Tighten the screws and snap the hinge pin covers on.
5. Recheck the seal.
6. If the door does not seal properly, replace the gasket.

Note Drawer slides do not require lubrication. Additional could impede
movement of the drawers when the lubricant is cold.

Control Panel
Thermo Scientific Recvo Blood Bank Refrigerators Installation and Operation 15
9 Control Panel
Figure 3. Refrigerator Control Panel
9.1 Control Panel
Features
The control panel is located on the top right side of your blood bank
refrigerator. You can use the three pushbuttons (#5, #8, and #9 in Figure 3)
to change the temperature display (#1) or to adjust temperature and alarm
setpoints. The thermometer display (#2) provides a quick visual indicator of
current cabinet temperature and alarm conditions.
Before starting up your refrigerator, take some time to review the control
panel functions:
1. Main temperature display — during normal operation, shows cabinet
temperature in degrees Celsius, as measured by the upper sensor inside
the cabinet. You can use the buttons to display other values such as
setpoints, extreme values, and lower sensor temperature. The number
in the main display flashes when the value can be modified.
2. Thermometer — shows cabinet temperature and alarm conditions.
There are 10 horizontal bars: 9 are displayed during normal operation,
the tenth (top) bar indicates a warm alarm condition. The number of
bars illuminated indicates approximate cabinet temperature.
Depending on alarm settings, 4 or 5 bars illuminated indicate that the
cabinet is at setpoint.

Control Panel
16 Installation and Operation Thermo Scientific Recvo Blood Bank Refrigerators
For example, suppose that the cabinet temperature setpoint is +4ºC and that
the warm and cold alarm setpoints are 8ºC and 0ºC. Then the number of
bars illuminated indicates cabinet temperature as follows:
When cabinet temperature exceeds the warm alarm setpoint, the top bar of
the thermometer flashes. When temperature is lower than the cold alarm
setpoint, the bulb flashes.
When you are in programming mode (described in Table 2) the
thermometer shows the setpoint value you are changing.
3. Power failure — illuminated when the main power supply is
interrupted. In this case the audible alarm also sounds.
4. Service required — illuminated when the controller is in service
programming mode or when simulated warm or cold alarm
conditions are failing to occur during an alarm test.
5. Increase — pushbutton used to increase setpoint values in
programming mode and for various display functions.
6. Door ajar — illuminated when the refrigerator door is open and the
alarm is activated (key switch turned to the alarm position). (This
feature is not available for 45 ft³ sliding glass door models.)
7. Battery low — illuminated when the backup battery is low.
8. Decrease — pushbutton used to decrease setpoint values in
programming mode and for various display functions.
9. Scan — pushbutton used to change the main display and for various
other functions.
10. Audible alarm — illuminates during warm and cold alarm conditions.
