CARBON M O NOXIDE POISONING HAZARD
Special Warning for Installation of Furnace or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.

Systems should be properly sized by heat gain and loss calculations made according to methods of the Air Conditioning
Contractors Association (ACCA) or equivalent. It is the
contractor’s responsibility to ensure the system has adequate
capacity to heat or cool the conditioned space.
CLEARANCES AND ACCESSIBILITY
The unit can be positioned for upflow, counterflow, horizontal
right or horizontal left operation. Zero clearance is allowed on
all sides for combustible materials. Thirty-six inches should be
allotted on the door side for maintenance and service.
To reduce risk of rusting, do not install the unit blower directly
on the ground or on a floor that is likely to be wet. In such
environments, the unit must be elevated by use of a sturdy,
nonporous material.
INSULATION
To ensure efficient operation, review the following precautions.
• If the unit is located in an area with high ambient temperature and/or high humidity, the air handler may be
subject to nuisance sweating of the casing. On these
installations, a wrap of 2” fiberglass insulation with a
vapor barrier is recommended.
• The factory recommends insulating the duct running
through any unconditioned spaces.
To reduce operating sound and vibration transmission use flexible canvas duct connections at the cabinet.
INSTALLATION INSTRUCTIONS

pointing down. If the motor is not oriented with the connections pointing down, water will collect in the motor and cause
premature failure.
NOTE: After rotating motor, tighten motor mount to secure
motor. Be sure that the gap between the motor and the insulation is the same as it was before loosening the motor mount.
This will ensure that the blower wheel is properly spaced inside the blower housing.
TO PREVENT PERSONAL INJURY OR DEATH DUE TO ELECTRICAL SHOCK ,
DISCONNECT THE ELECTRICAL POWER BEFORE ELECTRICALLY CONNECTING
THE UNIT.
TO AVOID THE RISK OF PROPERTY DAMA GE, PER SON AL INJURY OR FIRE
USE ONLY COPPER CONDUCTORS.
CAUTION
TO AVOID THE RISK OF PERSONAL INJURY, WIRING TO THE UNIT MUST BE
PROPERLY POLARIZED AND GROUNDED.
WARNING
ALL WI RING MU S T COMPLY WITH APPLI CABLE LOCAL AND NATIONAL C O DES.
TYPE AND LOCATION OF FUSED DISCONNECT SWITCH(ES) MUST COMPLY
WITH ALL APPLICABLE CODES AND PROVIDE OVERCURRENT PROTECTION AS
SHOWN ON THE NAMEPLATE.
HIGH VOL T AGE WIRING
If heater kits will not be installed, remove the proper size knockout for the electrical conduit connection. Connect electrical
conduit to the unit using two washers to make an approved
connection.
The power supply wires must be connected to the red and
black power wiring. Two wire nuts are provided in the bag
assembly for this connection. Wrap the wire nuts with electri-
4
cal tape. (Insulated crimp type connectors, field supplied, may
be substituted for the wire nuts and electrical tape provided
proper size connectors are used.) A ground wire MUST be
connected to the ground lug inside the unit.
LOW VOL T AGE WIRING
Low voltage wiring connections are made at the top of the cabinet. See the “Thermostat Wiring” section of this manual for
typical low voltage wiring connections. A minimum 18 AWG
wire must be used for installations up to 50 feet and 16 AWG
wire for installations over 50 feet.
MISCELLANEOUS ELECTRICAL
The unit transformer is factory connected for 240 V operation.
If unit is to operate on 208 V, disconnect the red wires from
terminal 3 of the unit transformer and connect them to terminal
2 of the unit transformer.
INSTALLER: It is important to follow these instructions when
installing the MB series of air handlers.
THERMOST AT CONNECTIONS
The following composite wiring diagrams detail various configurations in which your MB air handler can be used. Examples
include single stage cooling, two stage cooling and heat pump
with single or two stage electric heating. All these configurations can be applied with convenient connections to outdoor
thermostat applications.
The following sections will be detailed:
• Single Stage Cooling (GMC Thermostat part # CHT1860 or equivalent)
• Heat Pump (GMC Thermostat part #HPT18-60 or equivalent)
• Two Stage Cooling with Conventional Two Stage Thermostat (GMC Thermostat part #CHT90-120 or equivalent)
• Two Stage Cooling with Conventional Two Stage Thermostat (Encoded with Add-on Diodes)
• Two Stage Encoded Thermostat from Goodman Manufacturing Part #CHET18-60
Each diagram details the connections between room thermostat and MB air handlers, and the connections between the
MB air handlers and the Condensing Unit (or Heat Pump) with
optional connections to Outdoor Thermostats. For each configuration,
refer to the explanation of the proper jumper(s) to remove for
the corresponding blower speed that will result in the programmed ECM
TM
motor on MBE units.
Important: When matching the MBE air handlers to a single
stage cooling unit or heat pump, remember to connect the “Y/
Y2” thermostat connection on the Variable speed board (VSTB)
to the thermostat. Connecting “Y1” will result in first stage
cooling blower speed.
Note: The two stage configurations are illustrated to detail connections to the two capacity condensing units and heat pumps.
An equivalent thermostat can be used in place of the Goodman
thermostat part number. The GMC thermostats listed are
mercury type.
When utilizing the encoded version of a conventional two stage
cooling and heating electronic thermostat (add-on diodes), a
hard wire “C” (common of 24V secondary voltage) must be
used. This encoded version will not work with a “power robbing”
thermostat (i.e. no common connection). One TSTWK01 kit
is required for the encoded applications on MBE units.
NOTE: When using a conventional two stage thermostat for cooling
or heat pump applications with a two stage compressor, dip switch
#4 must be set to the “OFF” position on MBE units.
MBE MOTOR
This section references the operation characteristics of the
MBE model motor only. The ECM control board is factory set
with the dipswitch #4 in the “ON” position and all other
dipswitches are factory set in the “OFF” position. For most
applications, the settings are to be changed according to
the electric heat size and the outdoor unit selection.
The MBE product uses a General Electric ECM
TM
motor. This
motor provides many features not available on the traditional
PSC motor. These features include:
• Improved Efficiency
• Constant CFM
• Soft Start and Stop
• Improved Humidity Control
MOTOR SPEED ADJUSTMENT
Each ECM™ blower motor has been preprogrammed for operation at 4 distinct airflow levels when operating in Cooling/
Heat Pump mode or Electric Heat mode. These 4 distinct
levels may also be adjusted slightly lower or higher if desired.
The adjustment between levels and the trim adjustments are
made by changing the dipswitch(s) either to an "OFF" or "ON"
position.
DIPSWITCH FUNCTIONS
The MBE air handler motor has an electronic control that contains an eight (8) position dip switch. The function of these
dipswitches are shown in Table 1.
