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 units may be located in a closet, utility room, attic, crawl space,
or basement. These versatile models may be used for cooling or heat
pump operation with or without electric heat or indoor coil.
Top or side power and control wiring, color coded leads for control
wiring, and electric heaters all combine to make the installation easy
and minimize installation cost.
Electric heat kits are available as field installed accessories. Single
phase kits are available from 2.5 kW to 25 kW. 208-230 volt three
phase kits are available from 10kW to 25kW.
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.
