CAUTIONS FOR USAGE
1. If the unit is unplugged or the power to the unit is interrupted, do not restart the unit for at least 5
minutes. This protects the compressor.
2. This inner cabinet is refrigerated by forced circulation of cooled air inside the chamber. Ensure that
the intake and exhaust air vents are not blocked.
3. Adequate space should be provided between the items inside the unit to allow air circulation.
4. The temperature alarm may be operated at the time of first start-up. The alarm will be canceled
automatically when the chamber temperature will reach the set temperature.
5. Check that the door is closed tightly. The door check lamp lights when the door is open. The
alarm buzzer sounds two minutes after door opening. The buzzer can be canceled automatically when
the door is closed.
6. Always open and close the door gently. Rough door operation may lead fall down of stocked items,
incomplete closing, or damage of door gasket.
7. Never store corrosive materials such as acid or alkali unless the container is completely sealed up.
Corrosion may lead to failure of the unit in time.
8. Once the chamber temperature has stabilized, put the items into the chamber in small batches to
minimize the temperature increase.
9. Fix the shelves securely and make sure to place any materials on the shelves Do not place items
on the floor of the chamber.
10. If an instrument requiring a power source is placed inside the cabinet, the cable can be lead through
the access port on the cabinet. After installation, a rubber cap should be used to seal the access port.
Failure to do this can affect the temperature uniformity inside the cabinet and lead the condensation on
the outside of the access port.
11. In case condensation forms on the front glass or frame due to a high humidity environment, wipe if
off with a soft and dry cloth.
12. Do not clean the unit with scrubbing brushes, acid, thinner, solvents powdered soap, cleanser or hot
water. These agents can scratch the paint or cause it to peel. Plastic and rubber parts can be easily
damaged by these materials, especially solvents. When a neutral detergent is used to clean the unit,
wipe it up thoroughly with a cloth soaked in clean water.
13. Check the condenser filter and clean it regularly. A dusty filter may cause temperature increase in
the chamber or compressor failure. (MPR-1013, MPR-1013R only)
