separate disconnect box for the air conditioner is required by electric
code. It is generally a metal box located on the outside of the house
near the air conditioner compressor. Dont confuse your disconnect
box with the EPD which is plastic and has lights on the front.
These disconnect boxes may be equipped with switch type breakers, cartridge

Warning: These devices contain high voltage and can be dangerous.
If youre unsure about resetting breakers or replacing fuses yourself,
contact an electrician or an air conditioning contractor.

a breaker or replacing a fuse can cause such a power interruption. With
units attached to Energy Partners devices, it is normal for your central
air conditioner to remain off for 2 to 5 minutes after the power has been
restored. (This is done to prevent surges on our system.) During this
time period, the red light(s) on the right side of the clear plastic window
will remain on for up to 5 minutes. Your air conditioner contractor should
be aware of this before working on your central air conditioner.
