Air Circulation
Running the Blower Continuously
Set the thermostat’s system mode to OFF and the
thermostat’s fan mode to ON. The blower motor should
run continuously. Check for air delivery at the register(s).
Ensure that there are no obstructions at the registers or
in the ducts.
blower Configurations
Determining Nominal System Capacity
To select the appropriate airflows for the air handler, the
nominal system capacity must be known. The nominal
system capacity is always the nominal capacity of the
outdoor unit. However, in some situations the nominal
system capacity may not be the same as the nominal
capacity of the air handler. Always refer to the nominal
capacity of the outdoor unit to determine the nominal
system capacity.
Selecting continuous low speed fan operation
(Standard Blower)
The air handler is equipped with an option of continuous
low speed fan operation.When G is energized without Y/
Y2, the air handler will operate using the cooling speed.
With G & Y/Y2 or Y/Y2 energized, the air handler will
operate in the selected cooling speed (including 40 sec
blower-off delay).
NOTE: The CFM values listed in Table 9 (page 22) are
not dependent on duct static pressure. The VSHE motor
automatically compensates for changes in duct static
pressure (within the limits of the motor).
Turning the Blower Off
Set thermostat’s fan mode to AUTO, the blower will shut
down immediately.
3-Speed Units
The blower speed is preset at the factory for operation
at the same speed for heating and cooling, by using the
jumping terminal on the blower motor and connecting it
to the desired speed with both the red and black wires
connected to the jumping terminal. NOTE: The control
board is programmed with a 40 second off delay in the
cooling mode for optimum system performance and
efficiency.
System Cooling
1. Set the thermostat’s system mode to COOL and fan
mode to AUTO. Lower the thermostat’s temperature
mode below room temperature and observe that the
blower energizes. Check the air being discharged at
the register is cooler than room temperature. Verify
unit refrigerant pressures are in order. Blower should
be turning in direction indicated by arrow.
CAUTION:
NOTE: DO NOT alter unit wiring.Listen for any unusual
noises. Locate the source and correct as needed.
To avoid personal injury or property damage,
make sure the motor leads do not come into
contactwithanyuninsulatedmetalcomponents
of the unit.
2. Allow the unit to run for several minutes and then set
the thermostat’s temperature above room temperature.
Verify the blower cycles off with the thermostat.
For optimum system performance and comfort, it may be
necessary to change the factory set speed. See Table 5
(page 19) for airflow data. To change the blower speed:
1.Disconnect all electrical power to the unit and remove
the upper door.
2.Remove the black and red wires from the blower motor
jumping terminal. Discard the blower motor jumping
terminal.
System Heating
1.Set the thermostat’s system mode to HEAT and the fan
mode to AUTO. Increase the thermostat’s temperature
above room temperature and observe that the blower
energizes.Checktheairbeingdischargedattheregister
is warmer than room temperature.
2. Allow the unit to run for several minutes and then set
the thermostat’s temperature below room temperature.
Verify the blower cycles off with the thermostat.
3.Connect the heating speed wire (red) and the cooling
speed wire (black) to the desired blower speed marked
on the terminal block of the blower motor.
Selecting Minimum Electric Heat Airflow
The minimum electric heat airflow setting controls the
minimum air flow that will be produced whenever electric
heater kits are used. When the electric heater kit is
energized along with a heat pump, the airflow may be
higher depending on the basic cooling/heat-pump airflow
setting. The minimum electric heat airflow is selected by
theredblowerwireon3-speedmodelsorsettingswitches

5.Restore power to the unit.
• Formaximumdehumidification,selectanairflownearthe
middle or bottom of the range for that nominal capacity.
Additional information on humidity control can be found
in the Humidistat and Delay Setting sections.
• For thermostats with a dehumidifier output, use a field
supplied wire to connect the thermostat’s dehumidifier
output to the terminal marked DHUM. The thermostat
should be set so that the DHUM output should be high
(energized) when dehumidification is needed.See also
Dehumidification Options section.
High Efficiency Units (Variable & Fixed Speed)
IMPORTANT! This air handler has been designed to
give the installer maximum flexibility to optimize system
performance, efficiency, and comfort. Because there
are so many different ways to set up the air handler it is
important to read and follow these directions carefully.
HMG**X1E & HCG**V1E series air handlers use high
efficiencycirculatingairmotorsthatcomeintwovariations
and both are controlled differently.The fixed speed motor
control board (Figure 16, page 24) controls the torque
and the variable speed motor control board (Figure 17)
controls the airflow at a constant CFM. Both boards use
the same control board.
IMPORTANT! If coil icing is observed, the basic cooling/
heat-pump airflow selected may be too low. Verify the
setting selected is within the range shown in Table 8 and
thatthethesystemisproperlycharged.Pleaserefertothe
instructionssuppliedwiththeoutdoorunit.Ificingcontinues
to occur, raise the selected airflow one or two steps.
Before operation, the air handler must be configured to
matchtheunitwiththesystem,systemoptions,andclimatic
conditions. When configured, the air handler responds
directly to the thermostat inputs, as well as the optional
humidistat (see page 13). During normal operation, the
motor will gradually change speeds during start-up, shut
down, whenthermostatinputschange, andwhentheduct
static pressure changes (vents closed or opened, filter
clogging, etc.). The air handler is configured by setting
the selector switches and removing jumper connectors.
NOTE: Variable speed air handlers with SEER ratings
higherthan15arematchedwitha2-stagecoolingoutdoor
unit. They are programmed to operate at 75% of the
selected airflow while the system is in the lo-cool mode
and 100% of the selected airflow while in hi-cool mode.
Dehumidification Options
(HMG**X1E or HCG**V1E Models Only)
Both motor control boards (Figures 16 & 17, page 24)
have a DHUM connection that allows the system to
increase the amount of humidity that is removed from
the circulating air. This is accomplished by reducing the
CFM and allowing the cooling coil to become colder.This
will only occur when there is a call for cooling. There are
many ways that this can be electrically wired.
Selecting Basic Heating Airflow
Fixed & variable speed motor control boards (Figures 16
& 17) contain a set of dip switches for setting the blower
speed.For HMG**X1E models, pins 1-4 set the speed for
heating. For HCG**V1E models, the A/B switch must be
set for the appropriate air handler size (either setting can
be used for 48K or 60K BTUH applications).The airflow is
set automatically based on the amount of installed heat.
For both HMG**X1E & HCG**V1E models, the cooling
speed is selected via switches 5,6,7,& 8. To determine
the appropriate switch settings for your installation, see
Tables 6, 7, 8, or 9 (pages 20 - 22).
1. If the room thermostat incorporates a humidity sensor
andDHUMoutput,connecttheDHUMonthethermostat
to the DHUM terminal on the motor control board.
2. If using a separate humidistat, connect the DHUM & R
terminals on the humidistat to the DHUM & R terminals
on the motor control board of the air handler. In this
option, the DHUM output of the humidistat must be set
to be normally open and closed when there is a call for
humidification. See Figure 11.
Selecting Basic Cooling / Heat Pump Airflow
3.If a humidistat is not available, it is an acceptable option
to connect the R & DHUM terminals on the motor
control board together with a field supplied wire. This
option causes the blower to run at a reduced CFM for
10 minutes after a call for cooling. NOTE: If outdoor
unit is a heat pump, connect the O terminal to DHUM.
Thebasiccooling/heat-pumpairflowiscontrolledbysetting
switches 5 - 8 on the motor control board (mounted on the
blower). All airflows for other modes of operation (except
electric heat) are determined by this basic setting. FAN
ONLY would deliver 50% of the selected cooling airflow.
Table 8 (page 21) lists the basic airflow values versus the
airflowselectorswitchsettingsandrangesofbasicairflow
settings recommended for each nominal system capacity.

NOTES:
•
•
Airflow values listed are for 240V operation. For
208V operation, multiply the CFM value by .95 for
HCG24V1E, HCG30V1E, HCG36V1E, & HCG42V1E units.
For HCG48V1E & HCG60V1E units, mulitply the CMF value
by .90.
When matched with two-stage outdoor units the airflow on
low (Y1 or W1) input only will be 70% of the values shown in
this table.
