IMPORTANT
Air ow required for PTAC units must not be restricted
by exterior plants or walls. Plants or shrubs must not
be planted in close proximity to the outside grille of the
PTAC unit. Vegetation planted too close to grilles will
cause discharge air to be recirculated, thereby increasing
electrical consumption. Warranty will be voided if it is
determined that the compressor life is shortened from
overheating due to close proximity of outside obstructions.
Note: Discharge air restrictions include, but are not
limited to:
• Vegetation
• Concrete walls or barriers
• Overhangs that do not allow discharge air to rise
• Installation of bug screen of any kind
• Outdoor louvers by others unless approved by the
factory
