MODEL 396/396VP/397/398/398VP SECTION 2.0
INSTALLATION
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).
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.”

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.
