ACCESSORIES:

The R8239 function can be achieved by plugging an appropriate R8222 or R8228 relay into an AT72H,J transforrner. The wiring hookups are similar to Figs. 5-9 with the exception of some leadwire colors. Order the appropriate relay, using Table I. The metal cover, Part No. 138705, is available to enclose the relay.

INSTALLATION

Caution: 

  1. Disconnect power supply to prevent electrical shock and equipment damage.
  2. Installer must be a trained, experienced service technician.
  3. Always conduct a thorough checkout when installation is complete.
MOUNTING

The R8239, AT72H,J and Q633A1OO7 mount on a standard 4 inch square junction box. Make wiring connections in the junction box; then fasten the fan center to the box, placing the junction box screws through notches in the fan center mounting plate. On receptacles without relays, select and mount the appropriate relay (Table I) and attach the relay cover. A label identifying the relay used (furnished with TRADE LINE models) should be applied to the relay cover.
NOTE: Relay may be mounted in any position. With the terminals pointing down, pickup voltage is increased by 12 percent.

WIRING

All wiring must comply with local codes and ordinances. Refer to information furnished with the system equipment or refer to Figs. 5-8 showing internal schematics and typical hookups for the fan centers. For R8239F, see Fig. 8; for Q633A1OO7, see Fig. 10. On Q633A1 007 Plate-mounted Relay Receptacle, leadwires are provided for additional relav pole positions. Insert the ‘required leadwires in the relay rec~ptacle as follows.

Determine the leadwire colors required for the relay and application desired (Fig. 10). Push the leadwire terminal into the receptacle plate from the side stamped
with the color code (Fig. 11). When inserting the leadwire, the tang on the quick-connect terminal must align with the small clearance slot in the terminal opening. Press the terminal in until it locks in place.

CHECKOUT___________________________

Always conduct a thorough checkout when installation is complete. Place the system into operation. Operate the system through at least one complete cycle to make sure that the system equipment and the fan center operates as intended.

SERVICE_____________________________

Caution: Disconnect the power supply to prevent electrical shock and equipment damage.

The relay in the R8239 is field replaceable. See Accessories in SPECIFICATIONS section for appropriate relay. To replace the relay use the following procedure:

  1. Remove the 2 relay cover screws and remove the cover.
  2. Remove the plug-in relay from the receptacle, and replace with new relay.
  3. Replace the cover and 2 screws removed in step 1.
