General Installation Information
• Metric fasteners are used throughout the analyzer assembly. 2 mm,
2.5 mm, 3 mm, 4 mm, 5 mm, and 8 mm hexagonal wrenches are re-
quired for servicing the analyzer.
• The torque specification for fastening M6 screws is 4.0 ± 0.7 Nm
(36 ±9 in-lb). The torque specification for fastening M10 screws is 9.0
±1.0 Nm (80 ± 9 in-lb).
Tools and Equipment Required
To install the analyzer, you need the following tools, equipment, and sup-
plies:
• Set of open-end wrenches for fittings.
• Set of metric hexagonal wrenches.
• Set of metric ball drivers.
• Torque wrench, calibrated, for fastening M6 screws and M10 screws.
• Wire cutters, strippers, and crimpers.
• Flat blade instrument screwdriver.
• Electric drill.
• Soft, nonabrasive cloth.
• Wrist strap (for grounding).
• Detergent-based leak detector (Snoop
®
or another suitable leak detec-
tion agent is permissible).
• One power-disconnect explosion-proof switch (breaker), rated for at
least 250 V
AC
, 3 A and certified for the hazardous location (to satisfy lo-
cal electrical codes, the switch must be certified by the local authority
for the appropriate hazardous location). The power-disconnect switch
(breaker) must be connected to and mounted near the analyzer, in
an easily accessible area. The switch (breaker) must be clearly labeled
(e.g., “AMETEK Model 933S Analyzer Main AC Power Disconnect
Switch”). For safety reasons during maintenance, this switch allows
the main AC power to be disconnected from the analyzer prior to
performing service on the analyzer. This switch (breaker) is to be sup-
plied by the custom er/end user.
• Supply of AC electrical supply cable, which must be approved by the
local wiring regulations and electrical codes for the hazardous location,
and which must be rated for minimum 80 °C (176 °F).
• Supply of 1/8" or 1/4" 316 stainless steel tubing for the Sample Line
(depends on required flow rate).
