SM5000 Sampling Module - DC Pump Model
2 Installation
2.1 General
Install the Pump Sampling Module in the correct area classified in your facility.
NOTE: The explosion-proof model hazardous area classification is Class I, Division 1, Groups A, B, C
and D. It is important that all local and national codes be followed when installing this model in a classified
area.
Double check the area classification of the Pump Sampling Module.
Refer to Fig. 3 to find the area classification label on your unit. Ensure that the gas monitor being used with
the sample pump is rated properly by referring to the gas monitor instruction manual for more details.
WARNING!
Do not mix units with different area classifications. All units used in a classified area must have the proper
area classification. Otherwise, an explosion hazard will exist, resulting in a possible explosion, injury or
death.
The Pump Sampling Module for a general-purpose (GP) monitor can be a source of ignition. Install, locate
and operate only in a non-hazardous area and in accordance with applicable codes.
If sampling from or exhausting into a separate location, the installation requires flashback arrestors at the
inlet from a hazardous location and at the outlet to a hazardous location, to prevent the propagation of igni-
tion of hazardous gases. Routinely check for pump system leaks that could create an explosive environment
inside the enclosure.
Read and follow all instructions, warnings and cautions pertaining to this gas monitor.
Failure to follow this warning can cause ignition of explosive environments resulting in serious personal
injury or death.
2.2 Mounting the Pump Sampling Module Unit (All Models)
(1) Locate the Pump Sampling Module and the gas monitor(s) in a clean, accessible location.
NOTE: Since the unit enclosure is non-corrosive, it can be mounted to the outside of a building or in
other wet environments. Note the temperature and RH requirements.
NOTE: Use of Teflon tape or non-hardening thread sealant for environmental reasons is acceptable.
NOTE: When installing multiple gas monitors, ensure all monitors have conduit seals placed within the
requisite distances as outlined in their respective user manuals.
CAUTION!
Ensure that Pump Sampling Module or the gas monitor(s) display(s) are not blocked or obscured. A blocked
display will obscure the gas reading indication and sampling module indications. The unit must be mounted
with the electrical input facing down and the label clearly readable.
(2) Mount the Pump Sampling Module and gas monitor(s):
• From the electrical condulet or
• By using optional mounting bracket (P/N 10047561) and the four holes in the rear of the
Pump Sampling Module.
• By using the optional mounting bracket (P/N 10179361) for the Ultima X5000 Gas Monitor.
• Assemblies are also available that will allow monitoring in vent pipe lines 4-6" in diameter.
Use PN 10147544 for digital sensors and PN 10126895 for XIR/XIR PLUS sensors.
