Do not touch any electrical components or power cord if your hands are damp or
wet. Such action might lead to an electric shock.
After restarting your unit after a power outage or shutdown, ensure that all settings
are correct. Accidental change in setting may damage the stored products.
Do not place any water container or heavy object on top of the unit. A falling object
may injure an operator. If the water spills into the unit, it may damage the insulation
causing electric shock.
Do not climb on top of the unit or place any object on top of the unit.
Falling
equipment may cause injury or property damage.
Hold firmly onto the handle to close the door to avoid pinching your hands.
Do not place any glass container or enclosed container in the freezer.
These
containers may crack at cold temperatures causing injury to operators.
Do not use bare hands to directly handle the stored products. The cold temperature
of the products and the interior wall may cause the skin to burn.
During any repair operation, gloves should be worn to avoid injury by sharp edges
or corners.
The air filter for the condenser should be cleaned regularly. Freezer temperature
could be compromised.
If a unit is out of service for a long period of time, make sure the power cord is
unplugged. Deteriorated insulation on the power cord may lead to electric shock or
fire.
When a CO backup system is activated, the ventilation in the freezer room must be
monitored. Increased CO concentration in the air can be harmful and even fatal.
Do not tilt the unit more than 45 degrees when moving the unit.
