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
nal 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 so, 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 aer
calibrating.
7. Place the setpoint slider to the desired
temperature and replace the cover.
Throttling Range
Throling 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 throling range. The approximate throling
range seing is stamped on each lever in both °F and
°C. If it is necessary to change this seing, reverify
calibration aer 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 ts 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 aer 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.)
