PRECAUTIONS FOR SAFE OPERATION
Never install the unit in a location where corrosive materials such as sulphur compounds are
likely to be generated (e.g. near a drainage facility).
Corrosion of the copper pipes may result in
the deterioration and consequently the failure of the cooling unit.
This unit must be plugged into a dedicated circuit protected by a branch circuit-breaker.
Use a dedicated power source as indicated on the rating label attached to the unit.
A
multiple-tap source may cause fire due to excessive heating.
Do not climb on top of the unit or put any objects on the unit.
Falling from the unit may cause
injury; falling objects may cause damage to the unit
Never store corrosive substances such as acids or alkalis in this unit except in a sealed
container.
These may be harmful to your health and may cause corrosion of internal components or
electrical parts.
Check the settings when restarting operation after a power failure or after turning the power off.
The settings may have changed as a result of stopping the unit. Stored items inside the unit may be
adversely affected when operation is resumed if the settings have changed.
To ensure the safety of the service engineer, submit a safety check sheet with the required
items filled out.
This is provided as the photocopiable “Safety Check Sheet” at the end of these
operating instructions
Do not touch the power supply joint of the temperature recorder(option).
It may cause electric
shock.
To prevent frostbite, wear
protective gloves when handling
frozen items in the chamber.
Too
much frost may cause
chamber temperature rise
resulting from incomplete door
close.
