1.1 Installation

Remove all packaging materials and tape. Open the doors

to ventilate the unit. If the outside of the unit is dirty, clean with

a neutral detergent and rinse

with clear water.

Adjust the leveling feet by

rotating counterclockwise

(Figure 1-1) until all feet are in

full contact with the floor.

Ensure the unit is level.

Secure the unit to the wall

using the two fixtures (hooks)

attached to the back frame

(Figure 1-2). Attach a rope or

chain between the wall and the

fixtures. If holes can be drilled

in the wall, use the 10.5mm

bolt/nut supplied. This can be

used on a concrete wall only.

Locate the Model 3678 Refrigerator on a level, sturdy sur-

face capable of supporting the unit weight [277.8 lbs. (126kg)].

The refrigerator needs to be out of direct sunlight and away

from heat-generating sources. Four inches (10cm) clearance is

required on all sides for ventilation.

Make sure the power outlet is grounded. Do not use an out-

let without a ground.

1.2 Start-Up

1. Connect the unit to dedicated power supply and turn on

the power switch. Do not put any product in the unit at

this time.

pressing the alarm buzzer stop key

(BUZZER).

3. Set the desired temperature.

4. Confirm that the chamber temperature is at

the desired temperature.

5. When the unit is working properly, begin

slowly placing product into the chamber to

minimize temperature rise.

1.4 Refrigerator/Freezer Components

1. Glass window: Water can sometimes condense on the

glass in areas of high humidity. Wipe off the condensa-

tion with a dry soft cloth.

2. Magnetic door gasket: This prevents the cool air from

escaping. Always keep the gasket clean.

3. Control panel: Operation status is displayed on this

panel. Temperature settings are also available through

this panel. Refer to Section 1.3 for details.

4. Mounting space for temperature recorder: Space for an

automatic temperature recorder available separately.

5. Light: This light illuminates the chamber when the

refrigerator door is open.

6. Air intake vent: Ensure this vent is never blocked.

Failure to do so will result in unstable temperature dis-

tribution in the refrigerator.

7. Circulating fan: This is for cooling the refrigerator uni-

formly. The fan is installed inside the enclosure. Do not

insert anything into the enclosure. The air exhaust vent

is located at the upper edge of the fan.

8. Lock: Turn key clockwise 180 degrees to lock the door.

10. Power switch: The power switch also functions as a cir-

cuit breaker. Normally, a cover is placed over the

switch. The round button under the power switch is a

leakage test button. An operation check of the circuit

breaker can be performed by pressing this button. Make

sure the power supply to the unit is disconnected when

this button is pressed.

11. Remote alarm terminal: This is used to alert the user at

a remote location to the alarm condition. See Section

2.3 for details.

12. Leveling feet: Use the bolts to adjust the height and

level the unit on installation.

13. Cool air exhaust vent: Ensure this vent is never

blocked. Items exposed to the direct air flow can be

frozen.

14. Shelf: Shelves are available for each area.

15. Shelf (at the opening between upper and lower cham-

ber): Ensure this surface is never blocked by stored

items so that the cool air can be circulated into the lower

chamber.

16. Movable center pillar: The pillar contacts the door gas-

ket firmly when the door is closed and functions as a

block between the chamber and outer air. When the

door is opened, the pillar angle is changed by 90

degrees. Do not to change the pillar angle.

17. Protective sheet: Stored material may be frozen if it is

placed directly on the chamber floor. Always place the

sheet in the refrigerator compartment (upper and lower

left chamber).
