FREEZER COMPONENTS

1.Door: To open the door, grip the handle.

2.Handle: Always grip the handle to open the door.

3.Door latch: To lock the door, turn this latch downward. A padlock is also available.

4.Access port: This is used for leading the measuring cable from the freezing chamber to the outside. MDF-U333 and MDF-U537 has one port and MDF-U537D has two.

5.Lock: By turning to 180 degree to counterclockwise with a key, the door can be locked.

6.Control panel: To display the temperature setting and running condition. See page 10 for details.

7.Caster: 4 casters are provided for easy movement. Separate the front 2 casters from the floor by adjusting the leveling legs at the time of installation.

8.Defrost mark: When this is hidden by frost, defrost the freezer. Refer to page 23 for instructions.

9.Leveling foot: Serves to adjust the height and to settle the frame evenly.

10.Space for temperature recorder: An automatic temperature recorder (optional part) can be attached here. See page 13 “Temperature recorder”.

11.Storage container: Made of styrol resin. Be careful not to damage the container by a metal scraper at the time of defrosting.

12.Defrost water vessel & storage container: The container can be used to collect the defrosted water when defrosting.

13.Remote alarm terminal: Used to notify an alarm condition of the unit to remote location. See page 18 for details.

14.Battery switch: Switch for battery used for power failure alarm. Always keep “ON”. Turn the switch “OFF” when the unit is in no use for a long period (more than 1 month).

15.Power switch: Switch for the freezer. This switch also activates as an over-current breaker (15

A).
