General Procedure
Controls
The TH 192 Adapter Kits are designed to convert most existing pneumatic room
thermostats to Powers TH 192 or 194 Series or
Thermostats.
The Universal Adapter Kit contains the parts needed for all conversions. Adapter Kits
"A" and "B" do not contain all the parts that are included in the Universal Adapter Kit.
Therefore, kits "A" and "B" are suitable only for specific conversions.
See Table 1 to select the required kit and also to locate the page where the parts used
in a specific conversion are indicated.
The following general procedure applies for all thermostat installations. Notice that
some installations will require the use of the adapter frame to cover up paint lines,
broken walls, spots, etc. For installations not covered in this bulletin, remove the old
terminal and connect directly to the tubing. See Figures 2, 3 and 4.
1. Remove old thermostat from the wall.
2. Remove terminal head and gasket from fitting.
3. Clean fitting surface if required.
4. See Table 1 and locate page on conversion being made.
5. Identify correct mounting parts and necessary instructions.
6. Proceed with the connections required. Secure all connections and install plug-in
adapters to the 5/32-inch (4 mm) plastic tube. Use blue adapter for the air supply
line.
NOTE: Either the polyethylene (hard) or polyurethane (soft) tubing is
recommended on each specific conversion. This selection is based on
the most compatible application.
