Installing The Control Box - Coleman 9330F4552 Installation Instructions Manual

1. Remove the control box assembly cover which is
held by two sheet metal screws. Feed the field lead
wires and ground through the strain relief found with
the control box.
2. Attach black supply conductor to black "pigtail" lead,
white to white and ground to green with wire nuts
provided in control box kit.
3. Insure that no bare wires can come into contact with
live electrical parts and that wires cannot be pinched
between the control box sides and lid. Insert the
strain relief into the control box entry hole to secure
the field wiring. Reinstall the control box lid.
4. Attach the thermostat wires to the control box per
illustrations below:

5. Connect the roof unit 115 volt electrical conduit to
the wirebox 9 pin receptacle and verify that the plugs
are properly aligned and have snapped together
securely.
6. Locate the two machine screws inside the evaporator
cover of the upper unit. Align the control box over
the screws and use the wing nuts supplied with the
control box to secure it to the upper unit enclosure.
See Figure 2 for control box orientation in 48000 and
49000 series units. See Figure 9 for 47000 series
units.
7. Insert the evaporator freeze sensor between
evaporator fins near the bottom center of the
evaporator and between the bottom two tubes (See
Figure 2). Insert straight in until contacting the
staggered tube directly in back of the insertion point.
When contact has been made, elevate the exposed
end of the sensor approximately 45 degrees, then
continue insertion at a 45 degree angle until the
sensor is completely embedded into the evaporator.
