Installation Serinus 51 User manual 1.0
12
• Sample inlet pressure should not exceed 5 kPa above ambient pressure
• Tubing must be cut squarely and any burrs removed
• Remove nut, insert tubing through back of nut with tube extending 1 inch
through front
• Place tubing into port until it hits the tube stop inside fitting
• Move nut onto fitting and tighten nut (clockwise) finger tight
• Nuts should be re-tightened when instrument reaches operating temperature
Sample port
The sample port must be connected to an ambient source of sample air. When using a
sample manifold the Serinus requires at least 1.5 slpm delivered to sample manifold
(1.08 slpm for measurement plus approx 50% overflow).
Calibration port
The calibration port should be connected to the span/zero source. It is recommended
that a gas calibrator be used with SO
2
source to deliver precise concentrations of SO
2.
Exhaust port
The exhaust port is where the measured sample is expelled from the analyzer. The
exhaust tubing should be fitted to a vacuum pump (minimum: 1 SLPM at 50 kPa), if
the internal pump is not installed in your analyzer.
It is recommended that exhaust air is not expelled into a shelter/room inhabited by
people, it should be expelled into the external air, away from the sample inlet.
2.3.2 Power connections
When connecting the power source the following must be adhered to:
Warning
The following points MUST be followed;
incorrect setup and activation of instrument
may cause damage and will void warranty
• Verify that the red switch (above power switch) is switched to the correct
setting (240V or 110V)
• A three pin power plug (with ground) MUST be used with an earthed power
socket (3 pin)
• Connect the power plug into the mains power point and turn the power switch
on
