Unpowered Convenience Outlet
Unpowered Option (FIYCOUP)
1.
When the unpowered convenience outlet option is
installed, remove the receptacle.
2. The field wiring should be routed through the hole in
the base for downflow applications or front panel for
horizontal applications then through holes provided in
the “J” box (bottom for EMT and top for flexible
conduit).
3. Connect the three (3) wires to terminals inside outlet
box.
Return Air Smoke Detector
Pre-Requisite
Note:
The following field installation instructions apply
to downflow only. Horizontal return air smoke
detectors require no field installation.
When a unit is ordered with a downflow economizer and
a return air smoke detector as factory installed options, the
return air smoke detector cannot be completely installed
because the economizer, when it is in the shipping
position, is occupying the space where the return air
smoke detector is to be installed.
The partial assembly and set-up required for each factory
installed economizer must be completed up to the point
where the barometric relief hood is to be installed into the
unit. Prior to this operation, go to Step 5 of this instruction
and perform the operations described there. After this is
completed, the economizer installation is to be completed
in its entirety as outlined in the installation guide.
Smoke Detector Installation
Important:
The shipping screw that holds the
barometric relief damper must be removed
before proceeding with the smoke detector
installation.
After completion of the economizer installation as outlined
above, proceed with the installation of the return air
smoke detector as follows:
1.
Remove the smoke detector assembly from its
shipping position in the indoor fan compartment. This
assembly is attached with three screws to the indoor
fan board near the top of the unit.
2. Remove and discard the shipping bracket from the
smoke detector assembly. This is the angled piece of
sheet metal that secured the smoke detector assembly
to the interior parts of the unit during shipment.
3. Place the end of the smoke detector 16 inch metal
exhaust tube provided into the bottom hole in the back
of the smoke detector. Line up the tab in the exhaust
tube with one of the slots in the detector and insert the
tube until the tube can be rotated. Rotate the tube 45
degrees to lock it in place.

WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with an appropriate
voltmeter that all capacitors have discharged. Failure to
disconnect power and discharge capacitors before
servicing could result in death or serious injury.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.
