Securing the Inner Cones

STEP 1. STEP 3.

Insert the inner cone assembly upwards into the outer cone assembly
aligning the inner cone assembly tangs with the receptor slots on the
outer cone assembly.

“L” shaped retainer brackets are shipped retracted and must be adjusted
upwards against the outer cone. After installation of the inner cones, as
described above, each “L” slide retainer should be released and extended
upward against the outer cone.

STEP 2.

Rotate the inner cone assembly 10 degrees so that the retainer point
has passed the receptor slot and the weight of the inner cone assembly
is supported by the receptor slots of the outer cone assembly. A set of
spring clips apply pressure to the tangs locking the tangs into the recep­tor slots.

STEP 4.

Lock each “L” slide retainer in place with the screw provided to prevent
release of the tangs on the inner cones from the receptor slots.

Models TMRA and TMRA-AA adjustable round ceiling diffusers are designed for both heating and cooling applications. All
sizes have four cones, giving uniformity of appearance where different sizes are used in the same area. They deliver a uni­form 360° discharge pattern and exhibit excellent performance in variable air volume systems.

TMRA, TMRA-AA

The circular shaped TMRA diffuser has a unique 4-cone design
that minimizes pressure loss and provides excellent air distri­bution and occupant comfort. The adjustability of the TMRA
allows for use in both cooling and heating applications.
