2. Using a level, verify that the vessel mounting flange is level

in all directions within 3Â°.

3. Position the head flange gasket on the vessel flange and gen-

tly lower the displacer into the vessel. To prevent damage to

the stem/spring assembly, avoid tipping the unit or, in any

way, putting lateral forces on the stem.

4. Align the flanges and ensure that the gasket is seated properly.

5. Install the flange bolts and nuts and tighten alternating nuts

in a star pattern. Flange bolting torque specifications are

listed on page 9.

1.2.2 External Chamber

1. Remove the shipping strap and wire assembly which secures

the displacer in the chamber during shipment. This assem-

bly must be removed through the bottom connection or

drain.

2. Using a level, verify that the vessel mounting flanges are

level in all directions within 3Â°.

3. Align the Modulevel process connections with those on the

vessel and attach accordingly, based upon the connection

type. Appropriate gaskets and bolting will be required for

flanged connections. Install the flange bolts and nuts and

tighten alternating nuts in a star pattern. Flange bolting

torque specifications are listed on page 9.

1.3 QuickStart Wiring

WARNING: Explosion hazard. Do not connect or disconnect equip-

ment unless power has been switched off or the area is

known to be non-hazardous.

NOTE: Ensure that the electrical wiring to the E3 transmitter is com-

plete and in compliance with all regulations and codes.

(+) 1. Remove the cover of the upper wiring compartment of the

(-)

transmitter.

2. Attach a conduit fitting and mount the conduit plug in the

spare opening. Pull the power supply wire through the con-

duit fitting.

3. Connect an earth ground to the nearest green ground screw.

See Figure 1. Use a minimum 18 AWG rated up to 85Â° C.

4. Connect the positive supply wire to the (+) terminal and the

negative supply wire to the (-) terminal. For Explosion

Proof Installations, see Wiring, Section 2.5.3.

5. Replace the cover and tighten.
