Conduit

1.Seal the conduit threads with thread sealant. (The transmitter conduit seal interface was qualified using Grafoil™ tape.) Conduit threads mate with a standard 1/2–14 NPT male fitting.

2.Starting at zero thread engagement, install the conduit into the transmitter between 4 and 7 turns, or a minimum of 12.5 ft-lb (16.9 N-m). Hold the electronics housing securely to avoid damaging the threaded neck seal between the sensor module and the electronics housing during conduit installation.

3.Provide separate support for the conduit if necessary.

GAS SERVICE

Electrical	1.	Remove the cover from the terminal side of the transmitter
		(see Figure 2-5 on page 2-7).
	2.	Connect the power leads to the “SIGNAL” terminals on the transmitter
		terminal block (see Figure 2-7 on page 2-9). Torque the terminal
		screws to 5 in-lb (0.6 N-m), or hand-tight.
	NOTE
	Do not connect signal leads to the “TEST” terminals.
	3.	Recheck connections for proper polarity.
	4.	Check the cover O-ring grooves for cleanliness. If chips or dirt are
		present, clean the seat and mating portion of the cover with alcohol.
		Lubricate replacement O-ring with O-ring grease (RMT P/N
		01153-0248-0001 or P/N 01153-0053-0001). The transmitter was
		qualified using Dow Corning® 55 Silicone O-ring Grease.
	5.	Spray the inside threads of the electronics covers with cover lubricant
		(Rosemount P/N 01153-0333-0001 or equivalent) if necessary; if
		covers are already sufficiently lubricated, do
		not spray.
	6.	Carefully replace cover and tighten to 16.5 ft-lb (22.4 N-m).
