occurred.

DEFROSTING
The defrosting is activated when DEF key is pressed more than 5 seconds.
Remove and store the content to other freezer before starting the defrosting.

Place cotton bath towels at the

bottom of the freezer chamber before the start of defrosting as the defrost water will fall.
in order to quicken defrosting.

If bath towels are soaked, remove from the chamber, dry them and replace to

prevent water to drip out of chamber.

While you are defrosting . . . .
Freezer is desigried to send a buzzer message (but not remote alarm) for every 30
minutes to remind that the defrosting is in process, if the door is kept open. We
recommended that you would check the freezer at each buzzer to assure the water
absorbing material is dry enough to continue defrosting. Just in case you rather not
have a buzzer tone, you have a choice to either close the door (which will delay
defrosting) or unplug the power cord until defrost is completed.

MAINTENANCE
&WARNING
Always disconnect the power supply to the unit prior to any repair or maintenance of the unit in order
to prevent electric shock or injury.
Ensure you do not inhale or consume medication or aerosols from around the unit at the time of
maintenance.

These may be harmful to your health.

Cleaning
• Clean the unit once a month.

Regular cleaning keeps the unit looking new.

• Use a dry cloth to wipe off small amounts of dirt on the outside and inside of the unit and all accessories.
the outside panels are dirty, clean them with a diluted neutral dishwashing detergent.
can damage the plastic components.

If

(Undiluted detergent

For the dilution, refer to the instruction of the detergent.) After the

cleaning with the diluted detergent, always wipe it off with a wet cloth.

Then wipe off the cabinet or

accessories with a dry cloth.
• Never pour water onto or into the unit.

Doing so can damage the electrical insulation and may cause

electric shock or short circuit.
• The compressor and other mechanical part are completely sealed.

This unit requires absolutely no

lubrication.

Stacking two units
• You can stack two freezers, or you can stack this freezer and SR-L6111W (laboratory refrigerator) to double
the floor space efficiency.
833-0-3131-101-00.

To stack two units, you must order the stacking accessory kit part number

The stacking instructions in the accessory kit must be obeyed strictly for safety, as

stacking will bring the center of gravity significantly higher than when one unit is placed on the floor.

&WARNING
Always disconnect the power supply to the unit prior to stacking two units in order to prevent electric
shock or injury.
Any stacked combination of SAN YO refrigerator and I or freezer must be secured using all hardware
provided with the stacking accessory kit.
When stacking the freezer and the refrigerator, always keep the freezer at the bottom

TROUBLESHOOTING
If the unit malfunctions, check the following potential causes before calling for service.

In the case of

inadequate refrigeration or freezing, transfer the stored items to another freezer before checking.
If nothing operates even when the unit is plugged in
1. The unit is not connected to the power supply or capacity of power source is not enough.

2. There is a power failure, the fuse is blown, or the circuit breaker is activated.
When the unit does not accept changes of set-point temperature
1. The key lock is not "OFF".

See page 15 for "key lock."

When alarm is activated
On start-up

1. The temperature in the unit does not match set value.
In use

1. The door was kept open for a long time.
2. The set value was changed.
3. Vessels containing a high temperature load were put in the unit.
In these cases, the alarm may be deactivated automatically by running the unit for several hours.
When the unit does not cool adequately

1. The air exhaust vent is blocked by freezer contents.
2. A large amount of warm objects was put in the unit.

3. Some heat sources in the unit.
4. The door is opened frequently.
5. The ambient temperature is too high.
6. The unit is in direct sunlight.
7. The door is not securely closed.
8. The door seal is damaged or foreign substance inserted between the door gaskets.
9. Check the "offset," to make sure set temperature is not offset. See page 14 for "offset."

DISPOSAL OF UNIT
&WARNING
If the unit is to be stored unused in an unsupervised area for an extended period ensure that children do
not have access and that doors cannot be closed completely.
The disposal of the unit should be performed by appropriate personnel.

Always remove doors to

prevent accidents such as suffocation.
