PRE-INSTALLATION Check the carton and device for signs of damage.
INSTALLATION
TKS-5001 Transmitter is shipped with mounting screws and one inch copper tubes.
MOUNTING FITTINGS Use AT-516 wall box fitting for surface mounting on all surfaces and flush mounting on plastered or stud walls. Use standard 2" x 4" box for flush mounting on masonry walls (available through most electrical supply houses).
Mounting Location TKS-5001, TKS-5001-600 Locate the transmitter where it will be exposed to unrestricted natural air circulation representative of the average conditions. The transmitter should not be located near sources of heat or cold such as lamps, motors, sunlight, concealed ducts or pipes. TKS-5001-600 The pneumatic aspirated thermostat fitting is designed for flush mounting. When installing the wall box (AT-509), make sure that the front of the box is flush with the finished wall surface. The box is normally held in place by concrete block or masonry walls. Two holes are provided in the box for installation in lath-and-plaster walls. Using these two holes, the box may be attached to the lath, wall studs, etc., by means of wire, nails, or screws.
Note: When using the box in lath-and-plaster walls, seal around the fasteners after mounting the box to prevent wall air currents from entering the box. If desired, this fitting may be surface mounted.

TKS-6000 Troffer and TKS-7001 Diffuser Transmitters See specific installation instructions (page 4) for proper location.
RESTRICTORS A remote in-line restrictor is required when used for indication only or if the transmitter is more that 200 ft. (61 m) from the receiver controller. Use an AT-532-111-1-01 kit if restrictor is to be mounted under the cover.
Figure-2 Mounting of TKS-5001 to AT-516 Wall Fitting See Figure 2. 1. Remove and discard the cardboard cover plate on the wall box fitting, after the wall is plastered. 2. If the transmitter plastic tubing is too long for easy coiling in the wall box, it can be cut to length. Cut at a 45° angle for ease in inserting the tubing into the “O” ring seal. Be sure to cut the coil spring off with the tubing. 3. Remove and discard the short plug inserted in the connector head of the wall box fitting. 4. Insert the tube in the center hole in the connector.

Figure-10 Room Air Induced Over Transmitter by Discharged Air. Mounting of TKS-7001 Diffuser Transmitter Transmitter should be mounted to the face of the ceiling diffuser so that it projects downward into the room (See Figure 9). If the diffuser has an adjustable pattern, the discharge air direction must be adjusted to a horizontal pattern. This will insure a representative sample of room air over the element (See Figure 10). The transmitter will not perform satisfactorily if the discharge is adjusted to a vertical pattern.

Transmitter Mounting Procedure Using APNS-107 Kit 1. Drill a 5/16" (8 mm) hole for transmitter tubing. a. Figure 11. Locate hole center on an angled surface about 5/16" (8 mm) from an edge of the 1/2" (13 mm) square so as to avoid drill contact with the welded center plate mounting brackets.
Note: With toggle switches in the down (calibration) position, various temperatures can be simulated by using the manual adjuster.
b. Figure 12. Locate hole center on one louver about 5/16" (8 mm) from junction of two center back to back louvers. c. Figure 13. Locate hole center on an end louver about 1/2" (13 mm) from the junction of the louver and the mounting flange. 2. Bring field tubing through the 5/16" (8 mm) hole. If required, remove the louver assembly from the mounting flange. 3. Center the APNS-107 bracket over the 5/15" (8 mm) hole (use as a template) and drill 1/8" (3.2 mm) holes for the mounting screws. a. Figure 11. Drill two holes near edges of square center plate. Figure-14
b. Figure 12. Drill two holes, one each on bottom edge of back to back louvers. c. Figure 13. Drill one hole on end louver. 4. Assemble the transmitter to APNS-107 bracket as shown in Figures 10, 12, and 13. a. Figure 11. Cut off one side of APNS-107 as shown. 5. Make field connections to transmitter and push tubing up through the 5/16" (8 mm) hole. a. Wrap friction or electrical tape around the tubing and fill the 5/16" (8 mm) hole, preventing direct primary air passage over the sensor. 6. Attach APNS-107 as shown in Figures 11, 12, and 13 using #6 screws. a. Figure 13. Cover the crack between the end louver and mounting flange at least 12" (.3 m) on each side of the sensor. A 24" (.6 m) length of 3/4" (20 mm) tape stuck to the mounting flange can be used.
Receiver-Controller with Single Transmitter Located More Than 200 ft. (60 m) Up to Maximum of 1000 ft. (300 m) 1. Connect the calibration panel (Tool-100) to main air supply, the receiver-controller port 1 (note that restrictor is blocked) and AT-532-222-1-01 restrictor tee as shown in Figure 15. 2. Move toggle switch to the up (transmitter) position. 3. Measure the temperature at each transmitter with an accurate thermometer. (Make certain the transmitters are measuring a stable condition.) 4. Note the readings on the calibration panel gauges for the 50 to 100°F (10 to 38°C) range of transmitters used and compare these to the temperatures measured at the transmitters. Readings should be within +4°F (2.2°C). Replace the transmitter if the readings are not within these limits.
7. The transmitter installation is complete.
