Use properly insulated tools for any calibration work and do not make contact with any internal components Ensure that all high voltage components have been grounded use an earthing stick Ensure that power has been disconnected from the unit before any maintenance work is started FIRST LEVEL OF MAINTENANCE 7 2 Routine Maintenance The only routine maintenance required by the amplifier is periodic changing of the fan air filter and removal of accumulated dust from inside the tube cavity and from the air filter The periods between routine maintenance will depend upon operating conditions ambient temperature ambient dust levels and humidity It is advisable to carry out preventative checks at 3 month intervals and to change fans at least every 18 months or before if they become noisy or show signs of wear Periodic replacement of the tube will also be necessary The operating life of the tube is very dependant upon operating conditions for example line voltage fluctuations over 5 temperatures over 30 C high humidity the presence of dust and incorrect calibration of the amplifier will all result in a greatly reduced tube life SECOND LEVEL OF MAINTENANCE 7 3 Replacement of Components N B TO RE ASSEMBLE THE UNIT SIMPLY REVERSE THE SEQUENCE OF OPERATIONS N B THE FOLLOWING PROCEDURE SHOULD ONLY BE CARRIED OUT BY QUALIFIED PERSONNEL USING THE CORRECT TOOLS AND EQUIPMENT UNQUALIFIED OR INEXPERIENCED PERSONNEL NOT
