Installing the Zoneline
6. Connect the Top Ductwork
1. Use a field supplied clamp to clamp the flexible 10"
duct to the rigid ductwork above the unit.
2. Install the other end of the duct onto the air
discharge outlet. Use a field supplied clamp to
secure the duct to the air discharge outlet.
7. Connect the Remote Thermostat
The unit will be controlled by a remote thermostat.
IMPORTANT: The Zoneline thermostat connections provide 24V AC only. If using a digital/electronic wall thermostat,
you must set it to the 24V AC setting. See the Installation Instructions for the wall thermostat. NOTICE: Damage to
a wall thermostat or to the Zoneline electronics can result from improper connections. Exercise extra attention when
connecting blue and black wires. No line voltage connections should be made to any circuit in the thermostat. Isolate
all wires in building from line voltage.
1. Thermostat electrical connector is included with the unit. Follow the instructions included with the thermostat to
connect the thermostat to the unit.
