Installation, Operation and Maintenance Manual
GENERAL
Immediately inspect each unit for damage upon
receipt. File any damage claims with the freight car-
rier. Protect stored units from damage.
Use these instructions in conjunction with other ap-
propriate instructions, including but not limited to
those instructions supplied with the AHU or Fan Coil
unit or the outdoor unit (if applicable). Installation
must comply with all applicable local codes.
HOW TO USE THIS MANUAL:
Find the air handler/fan coil model section below and
use the following instructions to install the heater on
the unit.
Pay particular attention to the
following words:
NOTE–intended to clarify or
make installation easier.
CAUTION–given to prevent
equipment damage.
WARNING–to alert installer
that personal injury and/or
equipment damage may re-
sult if installation procedure
is not properly followed.
REQUIREMENTS:
These installation instructions are for installation of
auxiliary electric heater accessory “AEH” in Magic
Aire Belt Drive air handlers,
 INDOOR only,
 for the MODELS SPECIFIED only.
Instructions are primarily intended to assist qualified
individuals experienced in the proper installation of
heating and/or air handler units. All installations must
be in accordance with these instructions and all local/
national (NEC) electrical codes and standards and
NFPA 90A & 90B.

starting installation of heater kit on air handler dis-
charge opening. Improper installation, service, ad-
justments or maintenance may cause fire, electrical
shock or other conditions.
WARNING! To avoid the risk of electrical shock or
personal injury, lock out and tag out all electrical
power (may have more than one disconnect) to air
handler before performing any installation or service
maintenance work.
Installation and maintenance are to be performed
only by qualified personnel who are familiar with lo-
cal codes and regulations and are experienced with
HVAC equipment of this type.
WARNING: Sharp edges, coil sur-
faces and rotating fans are a po-
tential injury hazard – avoid con-
tact.

Note: C-48BM & C-60BM are interchangeable
with each other. C-90BM & C-120BM are inter-
changeable with each other.

ments are over the blower wheel discharge. If
the baffle is over the wheel severe loss of air flow
will result.
Secure heater to air handler with screws. Seal
the connection with tape or other means.
Service Clearance: Allow 36” clearance in front
of control box for service, or as required by local
electrical code.

GENERAL:
AEH heaters are offered standard with “Single Point Line
Connection” or “Single Point Power”, meaning that the
heater control box has all necessary parts to control both
the heating elements and the indoor fan motor on the
AHU. Single Point Power units include 24VAC controls
to allow a 24VAC thermostat to control the fan motor and
heater. Special order heaters may be supplied as “Dual
Point Power”, meaning they are equipped with only the
means of controlling the heating elements. Both single
and dual point offerings provide all required heater circuit
safety devices.
AEH Heaters may be selected using the New Magic 4
software (www.magicaire.com). The software calculates
the nameplate electrical data for the exact model number
specified.
