SECTION I: GENERAL
The MP modular air handler series provides the flexibility for installation
in any position. This unit may be used for upflow, downflow, horizontal
right, or horizontal left applications. These versatile models may be
used for air conditioning or heat pump heating.
These units may be located in a closet, utility room, attic, crawl space,
or basement. These versatile models may be used with heat pump
operation or for cooling with an indoor coil with no electric heat.
Top or side power wiring, control wiring, and color coded leads for
control wiring all combine to make the installation easy and minimize
installation cost.
SECTION II: SAFETY
This is a safety alert symbol. When you see this symbol on
labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation, which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation, which, if not
avoided may result in minor or moderate injury. It is also used to
alert against unsafe practices and hazards involving only property
damage.
