Filling Instructions
CFD-50 must be properly filled with clean drinking water before operation and use. During the filling process, use care and common sense and follow all local safety precautions.

Filling instructions can also be found on the inside of the water tank lid.

1. Step 1: Unlatch the water tank latch and fully open the water tank lid. Turn the fill plug counterclockwise to loosen and remove the cap. Keep the plug on top of the water tank while filling so it does not get lost.

2. Step 2: A funnel is shipped inside of each CFD-50. Install the funnel securely in the fill hole. Fill a bucket with clean drinking water. If there is no local source of clean drinking water, use bottled water.

3. Step 3: Pour 32 L of water into the water tank through tthhee ffuunnnneell.. IIff nneeeeddeedd,, uussee aa ssttooooll ttoo pprrooppeerrllyy rreeaacchh tthhee funnel and be able to look down into the fill tube to check the water level.

4. Step 4: While filling, stop periodically to check the water level by looking down into the tube with a light. The water should just reach the bottom of the fill tube.
   Do not insert sharp objects into the tube or you may damage the refrigerator evaporator.

5. Step 5: If you accidentally overfill the water tank, remove excess water using a piece of tubing as a siphon. Adjust the water level by adding/removing water until the water level is at the bottom of the fill tube.
   Too little water will reduce holdover time; too much water may damage the unit.

6. Step 6: When water is at the correct level, replace the fill plug and tighten until the plug is entirely within the lid and will not interfere when the top lid is closed.

Do not overfill the CFD-50 (Figure G). Remove excess water if overfilling occurs (Figure H).

Startup and Cooldown
Ensure that the water tank has been filled to the correct level before plugging in the CFD-50

1. Use a #2 Philips screwdriver to open the front electronics enclosure.
2. Connect the main battery. Once powered on, the temperature display will show the temperature of the vaccine chamber.
3. Plug the CFD-50’s power cord into a dedicated outlet. If mains power is available, the compressor will start after a delay of 5 minutes.
4. If telemetry module is installed, also connect battery on the telemetry module.
5. Open the vaccine cabinet door to check if interior light is on and close the door. To enable or disable interior light, refer to the maintenance manual.
6. If mains power is available, wait until compressor has started (indicated by green LED next to the temperature display) and verify that sides of the CFD-50 become warm to the touch after a few minutes of running, before replacing the electronics enclosure lid.
   • a. If mains power is not available, close the electronics enclosure and follow up the next day in person or by phone to verify the installation.
7. If compressor run LED does not come on or sides of the unit do not become warm after compressor has run for several minutes, consult troubleshooting section of the maintenance manual.
8. Do not use the CFD-50 until the display indicates that the vaccine chamber temperature is below 8 °C and the 30 DTR indicates at least 2 days of remaining holdover, which typically takes <6 hours with continuous power availability.

In the case of intermittent power (≤4 hours of power each day) and high ambient temperature environment, the CFD-50 may require 2 days after initial installation to reach full holdover capability.
During the initial cooldown, do not use the CFD-50 until the display indicates that the vaccine chamber temperature is below 8 °C and the 30 DTR display indicates at least 2 days of remaining holdover.

Use of the CFD-50

• Check the temperature display daily and make sure the chamber temperature is between 2 -8 °C before using.
• Do not overfill the vaccine chamber. Leave gaps between vials and boxes to enable cold air circulation within the chamber. Use trays to organize vac cines and keep boxes from touching the walls or sitting directly on the floor of the vaccine chamber.
• Keep vaccine chamber door tightly closed and latched when not in use to maintain the storage temperature inside
• There is no user-adjustable thermostat or sensors in the CFD-50.
• Designate a person to inspect and record the daily operation to ensure the safe use of the CFD-50.
• Only approved vaccines or medical supplies should be stored in the refrigerator. Do not store any foods, beverages, or flammable, explosive, volatile items (such as alcohol or gasoline) or other dangerous items in CFD-50.

Vaccine Chamber
All parts of the vaccine chamber are controlled between 2-8 °C and are suitable for vaccine storage. Loose vials should be stored in the provided trays on shelves inside the vaccine chamber. Secondary packaging may be placed directly on shelves or in trays. Do not place secondary packaging directly on the bottom of the vaccine chamber to avoid contact with any excess condensation. Also avoid leaving secondary packaging in direct contact with the chamber walls. When mains power is available, a LED light will illuminate the vaccine chamber when the door is open. If desired, the light can be disabled so it does not turn on when the door is opened – refer to maintenance manual for details. In humid environments condensation may collect on the sides and back of the vaccine chamber, and run down the walls into the drip channel surrounding the bottom of the chamber. Any accumulated condensation will flow to the back of the chamber and out through the drain hole.
