Section I: General
The single piece 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.
Top or side power and control wiring, color coded leads for control wir-
ing, 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 and 208/230 V three-
phase kits are available from 10 kW to 25 kW.
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.
FIRE OR ELECTRICAL HAZARD
Failure to follow the safety warnings exactly could result in serious
injury, death or property damage. A fire or electrical hazard may result
causing property damage, personal injury or loss of life.
