5. Electric Wiring
Warning:
Make sure that all power supply to the unit is disconnected before performing
any work on the unit to avoid the possibility of shock or injury and damage to
the equipment.
After the interior ceiling assembly frame is properly secured to the rooftop air
conditioner, you can start on the electrical connections.
● As shown in Figure 11, the outdoor unit has two sets of outgoing wires: the power
cord (high current) and the control signal wire. The power cord should be directly
connected to the terminal box while the control signal wire should be connected to
the control signal wire of the indoor unit.
● Use copper wire with ground and supply with a minimum of 14 AWG (not included),
for the wiring from the power source to the junction box. Do not attach them at this
time.
● Remove the 2 screws of the junction box cover. Take the power cord and push it
into the box through the strain relief clamp that is provided (see Figure 12).
