Maintenance and Cleaning

12.1 Cleaning the Exterior Cabinet
Wipe down the freezer exterior using only soap and water and a general use laboratory disinfectant. Rinse thoroughly with clean water and dry with a soft cloth.
Caution:
Avoid excessive use of water around the control area due to the risk of electrical shock.
Damage to the controls may also result.

12.2 Cleaning the Air Filter
The air filter should be cleaned four (4) times a year, minimum.

1. Open the right bottom door by pulling its bottom left corner.

2. Locate the grille on the door. See Figure 4-1.
   Grasp the middle of the grille material and gently pull out to remove.

3. Wash the filter material and gently pull out to remove.

4. Dry by pressing between two towels.

5. Install the filter back into the grille and attach the grille.

12.3 Cleaning the Condenser
The condenser should be cleaned once (1) per year, minimum.

1. Open the right bottom door by pulling its bottom left corner.
2.  Using a vacuum cleaner, exercising care to not damage the condenser fins, clean the condenser.

Depending upon environmental conditions, the condenser may need to be cleaned more frequently.

12.4 Defrosting the Chamber

1. Remove all product and place in another freezer.

2. Turn the unit off and disconnect from the power source.

3.  Open all doors and place towels on the chamber floor.

4. Allow the frost to melt and become loose.

5. Remove the frost with a soft cloth.

6. After defrosting is complete, clean the interior with a non-chloride detergent.
   Rinse thoroughly with clean water and dry with a soft cloth.

7. Plug unit in and turn power switch on

8. Allow the freezer to operate empty overnight before reloading the product.

12.5 Cleaning the Door Gasket
The door gasket should be cleaned monthly.
Using a soft cloth, remove any frost build-up from the gasket and door(s).
The door gasket may need to be cleaned more frequently if dirt or excessive frost build-up prevents the door from closing properly.

12.6 Vacuum Relief Port
The exterior door gasket provides an excellent seal to protect product, provide an energy efficient thermal barrier to keep cold air in and room temperature air out, and reduce frost build up on the inner doors.
Because the door gasket seals so well, a vacuum can be created after a door opening.
Warm air enters the cabinet, cools and contracts, creating a vacuum that pulls the door in tightly against the seal.
To equalise the pressure inside the cabinet after a door opening requires 1.5-3.0 cu.ft. of ambient air to be drawn into the cabinet. The amount of air required to equalise the pressure varies depending on the cabinet size, cabinet temperature, duration of door opening, inventory volume and the temperature/humidity of the ambient air.
The unit is designed with a “vacuum relief port” that allows the pressure to be equalised.
The time required to draw 1.5-3.0 cu.ft. of air into the cabinet depends on two factors:

1. the size and number of paths available for the air to enter the cabinet, and
2.  the pressure difference between the internal cabinet and the ambient room.

Cabinets with the vacuum relief port operating normally, (i.e. vacuum relief port is not iced over) will require a minimum of 30 seconds up to a maximum of 120 seconds for the cabinet to equalise. This is also a good indication that the exterior door is well sealed.
The vacuum relief port requires routine maintenance. It will ice over unless preventive measures are taken. If the vacuum relief port becomes iced over, the freezer will take several hours to equalize pressure.
Warning:
Do not leave the freezer unattended while the door is open.
Observe the inner side of port periodically for frost and ice build-up. Remove any frost with a soft dry cloth. If the tube should become clogged with ice, it must be cleaned.
Make sure during cleaning that the vacuum relief tube is completely free of ice to prevent rapid ice formation.
Factors that can affect the performance of the vacuum relief port include, high ambient temperature and high humidity conditions and frequent door openings.
Maintenance should be performed weekly or as needed.
Warning:
Failure to maintain the vacuum relief port may result in excessive ice build- up inside the tube, clogging the port, and inability to open the door. The vacuum relief port may need to be cleaned more often with frequent door openings and high humidity environments.

12.7 Replacing the Battery

1. See Figure 1-6 for the location of the battery power switch, turn the battery power switch to the off position (O).
2. Remove the left side plate fixing screw with a screwdriver to remove the left side plate, Remove the battery mounting bracket.
3.  Disconnect the battery connections.
4.  Remove the old battery and install the new battery.
5. Reconnect the battery.
6. Turn the battery switch to standby mode ( I )
7. Re-install left side plate.

Warning:
The % of charge can vary depending on the age, usage and condition of the battery. For a consistent and dependable charge, replace the battery every 2 years.  Replacement batteries must be rechargeable and are available from Being. Refer to the parts list for stock number and description of the replacement batteries. Dispose of the used batteries in a safe manner and in accordance with good environmental practices.
12.8 Preparing a Unit for Storage
Defrost the unit as described in ‘Defrost Freezer’. This will prepare the unit for storage. Turn off the battery power switch (O). Turn off the freezer power switch. Disconnect power to the battery(s) and to the freezer.
Warning: If the unit has been in service, turn it off and disconnect the power cord connector before proceeding with any maintenance.
12.9 Preventative Maintenance
12.9.1 Freezers
Your equipment has been thoroughly tested and calibrated before shipment. Regular preventive maintenance is important to keep your unit functioning properly.
