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.
2. On start-up, the alarm buzzer sometimes
operates. In this case, stop the buzzer by
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.
