To prevent the ingress of dampness all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.

Environmentally hazardous draining of refrigerant is an offense punishable by law.

-- Observe safety precautions when working on the high voltage system. Refer to HIGH VOLTAGE SYSTEM SAFETY PRECAUTIONS .

-- Pay attention to safety precautions for working near high voltage components. Refer to SAFETY PRECAUTIONS NEAR HIGH VOLTAGE COMPONENTS .

-- Note the high voltage system danger classification. Refer to HIGH VOLTAGE SYSTEM GENERAL WARNINGS .

-- See notes. Refer to WORKING ON REFRIGERANT CIRCUIT .
