temperature and/or water overflows from the unit. One way of discovering gross air leaks is to stand inside the enclosure
with the lights off, allow your eyes to adapt to the dark and look for light showing through cracks in the walls or around the
door. Also close the door on a piece of paper, if you can pull the paper through the door seal, it means air and moisture are
also entering into your enclosure. Because of the temperature difference between the inside and outside, very small cracks
can allow large amounts of outside air into the enclosure. Please be aware that moisture will pass through solid concrete,
brick, paint, paper and wood. A newly constructed room may contain fresh wood, paint, concrete and other building
materials containing large amounts of moisture. This condition can cause symptoms similar to a poorly sealed enclosure,
but will gradually go away.

(TUBE LOCATION)
EXCESS CONDENSATE DRAIN TUBE: Your unit is equipped with a Pull-down Drain tube to prevent condensate
overflow. This tube should only be used to temporarily drain excess amounts of condensate caused by excessive
moisture laden air entering the enclosure. The source of this air must be eliminated.
EXTENDING THE DRAIN TUBE: To extend and open the drain, use a pair of small pliers to grab the red plastic plug and
vinyl tubing. Pull the plug and tubing down approximately 6 inches until it snaps into the locked position and the "Grey
Fitting" is visible through the drain hole (see Fig. 4). Remove the bottom red plug. Now the cooling unit will drain any
condensate that is standing above 1/4 inch deep in the base pan.
CLOSING THE DRAIN TUBE: To close the drain tube, simply replace the "Red stopper" and push the vinyl tubing back up
into the bottom of the cooling unit. This action extends the top of the tube above the water line preventing it from draining.
CAUTION: Do not push the entire length of tubing back up into the drain hole.
INSTALLING A DRAIN LINE: To extend the drain tube into a basement drain or container, acquire a length of vinyl tubing
with an inside diameter of 1/2 inch from a local hardware store. Slip this larger piece of tubing over the Pull-down drain
tube. CAUTION: Always have the extended drain line running "down hill". This is a gravity flow system. If a horizontal run
is encountered, an air vent or condensate pump may be required to maintain drainage.
Do not drill or tap the drain hole. Doing so will result in rusting of the metal base and void the unit's warranty.
