Optional Constructions
Packing Nut
Part FTG13A-600R is available
for closed tank applications
where the temperature does not
fall below -35°F (-37°C) or
exceed 250°F (121°C).
Maximum liquid pressure limit is
150 PSIG (1034 kPa). For
applications where the
temperature or liquid pressure
exceeds these limits, specify
Style 4 element with all metal
packing nut as an integral part of
the control.
Ordering Information
To order, specify the Product
Number only. If the Product
Number is not available, specify:
1. Type Number.
2. Range required.
3. Type of bulb, clamp-on or
coiled.
4. Capillary length, if other
than 6 feet.
5. Specify bulb well part
number if required.
6. Specify Part Number
FTG13A-600R packing nut
assembly, if required.
Installation
Mounting
Controls are normally mounted
to a flat surface by two mounting
holes 3/8 in. in diameter. (See
Dimension Drawing.) For closed
tank applications without a bulb
well assembly, Part FTG13A-
600R packing nut assembly may
be supplied on -30 to 50°F and
20 to 80°F ranges only. See
Fig. 3 for sequence of
installation.
!
CAUTION: Turn off liquid
supply and relieve pressure
before installing or
removing the bulb or bulb
well.
Place parts over support tube
section of the element, placing
bulb into tank (be sure tank is
first drained so liquid level is
below tank opening). Screw
packing nut into the adapter with
the retaining washers and
packing in place as shown.
To install models with bulb well,
first install bulb well into tank.
Remove bushing from bulb well
and slide over capillary. (See
Fig. 4.) Replace bushing into
bulb well, gently pushing bulb
into position in bottom of well.
Tighten set screw in end of
adapter to hold bulb in position.
!
CAUTION: Do not dent or
deform the sensitive bulb of
this control. A dent of
deformation will change the
calibration and cause the
control to cycle at a
temperature lower than the
dial setting.
