Installation Guide
Connections
The CTC-1611/1612 requires an HFO-0028 tubing kit
and a 14.4 scim restrictor T.
1. Insert the restrictor into the HFO-0028 tubing.
2. Connect the restrictor to Port T1.
3. Connect the open side of the T with tubing to the
final device actuator (DA unit for the CTC-1611
or RA unit for the CTC-1612).

Maintenance
Remove dust as necessary from the slots. Clean the
window with soft, damp cloth and mild soap.
Care should be taken to keep the unit clean
from dust during installation. Each component is
designed for dependable, long-term reliability, and
performance. Careful installation will also ensure
long-term reliability and performance.
6. Replace the gauge tap rubber cap after
calibrating.
7. Place the setpoint slider to the desired
temperature and replace the cover.
Throttling Range
Throttling range is the temperature required to
change the thermostat output pressure from 3–15 psi.
All CTC-1600 series thermostats are factory-set for
a 3° F throttling range. The approximate throttling
range setting is stamped on each lever in both °F and
°C. If it is necessary to change this setting, reverify
calibration after adjustment.
1. Remove scale plate (see the Scale Plate section).
2. Slide the black TR adjuster to appropriate value/
location.
NOTE: The hole in the TR adjuster fits a 1/16" hex
wrench. Gently rotate the adjuster back and
forth while sliding. Do not turn excessively!
3. Rotate back to a “square” position after adjust-
ment.
4. Reinstall the scale plate.
Calibration
These thermostats are factory calibrated and do not
require further calibration at installation. Should it
be necessary to change calibration:
1. Remove the cover and gauge tap rubber cap.
2. Install a gauge on the gauge tap using 3/32" ID
tube.
3. Measure the ambient temperature with an
accurate thermometer.
4. Move the setpoint slider to the measured ambient
temperature.
5. Use a 1/16" hex wrench and turn the calibration
adjustment until the test gauge indicates the
desired pressure. (Clockwise rotation decreases
the output pressure.)
