PRODUCT FEATURES AND BENEFITS (cont)
DURABLE CONTROL PANEL
DOOR AND EASY-TO-USE
CONTROLS
The reinforced control door conceals controls and fea-
tures an attractive surface that will not chip. The hinge
and door are extruded as one piece and provide protec-
tion from demanding transient use. The door is sloped
to discourage use as a shelf. Easily accessible from the
room side, the control buttons and thermostat are
clearly marked and simple to use.

WASHABLE VENT AIR FILTER

The unique duct system is activated by a two-position
control. Fresh outside air is redirected by the vent door
to an inside low-pressure area. A molded plastic filter
prevents dirt and debris from entering the room side of
the unit. The vent mechanism is made from noncorro-
sive material ensuring reliable operation. High-
pressure airflow creates a tight, draft-free seal when
the vent door is closed.
BI-DIRECTIONAL
DISCHARGE GRILLE
The discharge grille is made of durable polycarbonate
and is reversible. Air flows upward at an 80 degree
angle to the floor but can easily be adjusted toward the
horizontal for airflow at a 53 degree angle to the floor.
The discharge grille is cool to the touch during the
heating cycle.
