MODEL 396/396VP/397/398/398VP

Wrap the pipe threads of the Twin-Kam Kamloc coupler with Teflon tape before placing it into the process pipe. The coupler can be connected to any 1 in. process connection and must be mounted within 80° of vertical, with the elec- trode facing down. Once the coupler is in place, the adapter should be positioned onto the back end of the sen- sor. (See Figure 2-5) Remove the parafilm wrapping from the two 0-rings on the sensor, grease the o-rings with the lube provided, and feed the sensor cable through the adapter. Once the adapter is slipped over the sensor’s back end, the retaining ring (which is included with every 397 sensor) should be installed on the black, grooved, back end of the sensor body. The retaining ring secures the sensor into the adapter. The adapter/sensor assembly is now ready to be inserted into the coupler. With both arms of the coupler in the released position, insert the adapter/sensor assembly into the coupler.

NOTE

The adapter can not be inserted completely or properly unless both arms are in the fully released position (see Figure 2-5).

SECTION 2.0

INSTALLATION

Once the adapter has been properly placed in the coupler, both arms should be positioned in the locked position. A Sur- Loc™ 1 spring arm has been provided on one arm so that the “arm cannot be opened until the spring is released.”2

NOTE

The sensor may obstruct flow through smaller pipes.

Once the arms of the coupler have been locked in position, use tamper-evident safety wire on the metal rings of the Twin-Kam arms to prevent unauthorized and/or untrained personnel from using the Quik-Loc unit.

SAFETY WARNING

It is the responsibility of each com- pany using the Quik-Loc Kit/ 397 TUpH Sensor to train personnel of the injury risks associated with using a quick-release coupler that is placed in a hot or pressurized process.

The Quik-Loc unit should be used only within the pressure and temperature limits stated for the Model 397 sensor in Section 1.2.2.
