Figure 6: EWC10 Enclosure with VAV Controller
The VAV can be directly mounted into an EWC10/15 enclosure. You may
also purchase the VAV premounted in a EWC10 enclosure with a
50 VA transformer. Refer to the Application Specific Controllers
Technical Manual (FAN 636.3) for instructions on mounting the enclosure
to a wall.
To mount the VAV in the EWC10:
1. Orient the VAV so that its terminals face the low voltage wiring
trough (Figure 6).
2. Align the three mounting holes in the base of the controller with the
holes in the back of the enclosure. On the side with four mounting
holes, use the two outside holes for mounting in the EWC. See the
Universal Packaging Module Technical Bulletin (FAN 636.3) for a
more detailed explanation.
3. Secure the controller with three No. 8 x 1 in. screws. For best results,
use a plastite-type thread. A thread-forming or sheet metal thread type
may also be used.
Position the controller (or controller's enclosure) on the mounting surface
before installation to ensure the calculated mounting area is correct. You
can make precise measurements for distance between controller terminals
and sensor/actuator mounting points on the VAV terminal. Confirm
electrical power source and conduit requirements prior to mounting.
