!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury and/or death.

Prior to installation of this accessory, make sure all power is disconnected to the unit and locked out and tagged.

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.)

8.Install plug into far end of sampling tube.

9.Remove the unit side panel at the return end of the unit. Save screws for use later.
