How do I find the turbo button on an everstar air conditioner?

Hey there, just follow these simple steps then you'll be on your way
To connect the continuous drain option. Remove
the water tank from the cabinet. Inside the
cabinet (water tank area) you will find a section of
hose hanging beside the water tank, which is plugged
at the end. Remove the plug
from the end of the hose and install the drain hose connector
(included with this unit) into the
end of this hose section. Route the end of the
hose (with drain connection) into the water tank,
then through the hole provided in the face of the
water tank. Attach a section of garden hose (to
suit your continuous drain option requirements)
to the drain hose connector. Place the open end
of the hose directly over the drain area in your
basement floor.
Please make sure the drain hose
section routed through water tank does not interfere
with the correct positioning of the water tank inside
the cabinet, or the will fail-safe switch mechanism will
be activated, not allowing the unit to operate.

You need to have a service technician do it. If you do not know how, then you probably do not have the equipment or any way to get refrigerant. At $400 for a new one, it may not be worth it unless you have a friend that can help you.

It will run in the cooling mode until the condensate pan fills with water then it will turn off the compressor and operate in a fan only mode, no cooling.

SOURCE: i need to find a owners manual for an everstar portable air

Try going to the Danby website. They have owners manuals for many items that have been discontinued. Check to make sure you have the right model number as there is a white printed tag that they use as well as the one printed on the metal back. Sometimes they aren't the same. (Why, I don't know.) Otherwise, Google the number.
