Chassis Operation
Fresh Air Door
The fresh air door is an “intake” system. It is opened via
a slide mechanism on the front of the chassis located just
above the indoor coil. Move the slide left to open and right
to close the door. The system is capable of delivering up to
60 CFM of outdoor air.
Low Ambient Compressor Cut Out
Each chassis is equipped with low ambient protection
that is determined by thermistor feedback. The feedback
will prevent the compressor from operating at low suction
temperatures.
Room Freeze Protection
This feature will monitor the indoor room conditions and in
the event that the room falls below 40°F, the unit will cycle
on high fan with the electric heater. This occurs regardless
of mode.
Chassis Final Connections
With the chassis in place, you are now ready to begin
chassis connections:
A. Move the thermostat switches to “OFF” and “AUTO”.
This will keep the thermostat from cycling the chassis
until final connections are complete
B. Connect the duct work onto the 10” collar. Plastic
wire ties (field supplied) are suggested to secur
the duct work in place. Use 2 wire ties, one for each
inner and outer flex duct sleeve
C. Review the Final Installation Checklist before
replacing the power quick disconnect, reconnecting
power to the chassis, or operating the chassis.
