WARNING
NOTE
: For horizontal applications it is easiest to install the
smoke detector prior to making duct connections.
1. Open the hinged electrical/compressor access door and
secure.
2. Find the 2 plugs located above compressor B1/A2,
remove and discard. Cut holes in the insulation located be-
hind the partition.
3. Remove cover from smoke detector. The screws will
remain captured in the cover.
4. Slide exhaust tube into the sensor. The exhaust tube
should be inserted from the back of the sensor, into the
hole with four slots, and locked into place. (See Fig. 2.)
5. Slide smoke detector into holes in partition with the
ter-
minal block to the right. Do not secure at this time.
6. Slide the sampling tube collar over the sampling tube un-
til the tabs lock into the tube. (See Fig. 2.)
7. Slide long sampling tube (P/N RN20ZT060) into left--
hand hole of smoke detector. It might be necessary to tilt
the smoke detector upwards in order to properly align the
sampling tube,
making sure that the sampling holes
point DOWN.
(See Fig. 4.)
