Tools and Equipment Required
To install the analyzer, you need the following tools, equipment, and
supplies:
• Set of open-end wrenches for fittings.
• Set of metric hexagonal wrenches.
• Set of metric ball drivers.
• Torque wrench (for Type 200 Disconnect Enclosure), calibrated and set
to measure 9.0 Nm, ±1.0 Nm (80 in-lb, ±9 in-lb).
• Wire cutters, strippers, and crimpers.
• Flat blade instrument screwdriver.
• Electric drill.
• Thread lubricant (must not contain copper).
• 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 VAC, 3 A and certified for the hazardous location (to satisfy
local electrical codes, the switch must be certified by the local author-
ity 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 la-
beled (e.g., “AMETEK Model 900 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 loca-
tion, and which must be rated for minimum 80 °C (176 °F).
• A supply of 1/4" 316 stainless steel tubing (NPT-F connectors are
required) for the Instrument Air lines. Supplied by the customer/end
user.
• A supply of 1/4" 316 stainless steel tubing for the Span, Zero, and
Aspirator Drive Air lines. Length will vary, depending on the distance
between the analyzer and the sample stream. Supplied by the cus-
tomer/end user.
