Instrument Start-up
General Start-up Procedure
The MAX300-RTG is shipped with the vacuum system roughing pump oil removed.
The pump must be filled with the supplied bottle of oil prior to start-up of the
instrument. To load the roughing pump oil:
Remove the fill port plug from the top of the pump (refer to Figure 29, page
52)
Pour oil into the pump until visible-half way up the sight glass
Re-install the fill port plug
Caution: There may be slightly more oil in the bottle than necessary to fill
the pump. Do not overfill.
Once verified that the sample lines, calibration lines, and purge plumbing are
properly installed, the instrument may be turned on. Connect the MAX300-RTG's
power input to a power source of the specified electrical frequency, current, and
voltage (115V or 230V). The connections must be suitable for the classification of
the area in which the equipment is installed. All connections should be secured to
their electronic modules.
Power inside the unit is controlled by three main power distribution switches
located at the upper right of the enclosure (refer to Figure 28, page 51). The top
switch controls the air conditioner, pumps and vacuum system, the middle switch
controls the electronics, and the bottom switch controls the heaters. In normal
operation, all switches will be left in the ON position when the door to the enclosure
is closed. These switches also act as circuit breakers and can be reset by cycling
from OFF to ON.
If the area is known to be non-hazardous:
Make sure it is safe to apply power to the instrument
On Zone 1/Div 1 units, turn the override key to the “override” (on) position
