Indoor air flow may be determined by measuring the
external static pressure (ESP) of the duct system using an
inclined manometer or magnahelic gauge and consulting
the above chart to derive actual air flo . Under no
circumstances should the small chassis VTAC equipment
be operated at an external static pressure in excess of .3"
W.C. Operation of the VTAC under these conditions will
result in inadequate air flo , leading to poor performance
and/or premature component failure.

Control

For LOW speed only operation, connect the fan output
terminal from the thermostat to the GL terminal of the
electronic control.
For HIGH speed only operation, connect the fan output
terminal from the thermostat to the GH terminal of the
electronic control.
For thermostats with two-speed capability, connect the
LOW speed output to the GL terminal and the HIGH speed
output to the GH terminal.

VTAC Required Minimum Clearances

Building Exterior Unit Opening Requirements
VTAC units must be installed on an outside wall. Confined
spaces and/or covered areas should be avoided. Units
must be installed no closer than 12" apart when two units
are side by side. If three or more units are to operate next
to one another, maintain a minimum of 60" between units or
pairs of units (Figure B). If more than two units are sharing
a floor with adjacent, outset units, a minimum distance of
64" must be kept between units (Figure C). Also, a vertical
clearance of 60" must be maintained (Figure A) between
units. Units installed on the bottom floor must be mounted
at least 6" off of the ground.

Grill Clearance Requirements
Where obstructions are present use the following
guidelines for proper spacing from the VTAC exterior
louvered grill. Amana recommends that ALL obstructions
are a minimum of 72" from the exhaust.
For minor obstruction(s) such as lamp poles or small
shrubbery, a clearance of 24" from the outdoor louver must
be maintained.
For major obstructions such as a solid fence, wall, or other
heat rejecting devices like a condensing unit, a minimum
distance of 72" must be kept.
