SAFETY INFORMATION

Before installing and using the Transport GT24, take note of the fol- lowing precautions:

Read all instructions carefully.

Do not place the unit on an unstable surface, cart, or stand.

Do not block the slots and opening on the unit, which are pro- vided for ventilation.

Only use the power source indicated on the marking label. If you are not sure, contact the Power Company.

The unit uses a three-wire ground cable, which is equipped with a third pin to ground the unit and prevent electric shock. Do not defeat the purpose of this pin. If your outlet does not support this kind of plug, contact your electrician to replace your obsolete outlet.

Do not place anything on the power cord. Place the power cord where it will not be in the way of foot traffic.

Follow all warnings and cautions in this manual and on the unit case.

Do not push objects in the ventilation slots as they may touch high voltage components and result in shock and damage to the components.

When replacing parts, ensure that you use parts specified by the manufacturer.

When service or repairs have been done, perform routine safety checks to verify that the system is operating correctly.

Avoid using the system near water, in direct sunlight, or near a heating device.

Cover the unit when not in use.
