EC9830 CO ANALYZER OPERATION MANUAL

Warning
Power is supplied to the analyzer through a
three-pin power plug. The ground must not be
defeated and an adequate ground must be
connected to the instrument, both for proper
performance and for the safety of operating
personnel. The warranty on the analyzer applies
only if the analyzer is properly grounded. If it is
not properly grounded and electric power is
applied in violation of the National Electric
Code, ECOTECH assumes no responsibility for
any injury to personnel or damage to property.
Warning
Be sure to check that the mains power selection
switch is at the correct setting before turning the
instrument on. Failure to do so may result in
damage to the power supply.
Connect the power plug to the power receptacle and press the power switch to the
ON position on the rear panel. Also make sure that the DC POWER switch on the
front secondary panel is switched to ON.
