The Phoenix 300 must always be upright when

transported by vehicle. It may be tipped on to its handle

and back for loading and moving by hand.

2.2 Location

Note the following precautions when locating the

Phoenix 300:

• It is designed to be used INDOORS ONLY.

• If used in a wet area, plug it into a GROUND FAULT

INTERRUPTER.

• • • • DO NOT use the Phoenix 300 as a bench or table.

• It must always be used in the upright position.

• The air inlet on top & the side outlet must be at least

1 foot from walls and other obstructions to air flow.

• If the humid area is very large, dehumidification can

be improved by adding an outlet duct to circulate air

to stagnant areas (see Sec. 2.5).
