When heaters are installed maintain clearances from combustible materials as specified on unit rating plate. Do not use plastic
lined or combustible flexible ducting within 36
inches of the supply end of the air handler.
Failure to do so can result in fire, property
damage, personal injury and/or death.

GeneralInformation

Installation or repairs made by unqualified persons can
result in hazards to you and others. Installation MUST
conform with local building codes and with the
National Electrical Code NFPA70 current edition.
The information contained in this manual is intended
for use by a qualified service technician familiar with
safety procedures and equipped with the proper tools
and test instruments.
Failure to carefully read and follow all instructions in
this manual can result in equipment malfunction,
property damage, personal injury and/or death.

The blower cabinet may be used for cooling or heat pump
operation with or without electric heat. Installations without
electric heat, require a No Heat Kit. The cabinet can be installed in
an upflow, downflow or horizontal position (Figure 3, 4).

Location
Select the best position which suits the installation site conditions.
The location should provide adequate structural support, space in
the front of the unit for service access, clearance for return air and
supply duct connections, space for refrigerant piping connections
and condensate drain line connections. If heaters are being
installed make sure adequate clearance is maintained from
supply ductwork, See Clearances and Warning in Figure 1.
Ifthe unit is located in an area of high humidity, nuisance sweating
of casing may occur. On these installations a wrap of 2" fiberglass
insulation with a vapor barrier should be used.

The 24 volt power supply is provided by an internally wired low

supply is 208 volt, the low voltage transformer must be rewired to
the 208 volt tap. See the unit wiring label.

Install the strain relief bushing (supplied with unit) in the hole.
Connect the field wiring at the screw terminals of the control

Keep the low voltage wiring as short as possible inside the control
box.
Complete connections between indoor blower, outdoor section,
indoor thermostat and electronic outdoor thermostat (accessory)

Adding Humidistat or Outdoor Thermostat
Adding a humidistat
or outdoor thermostat
allows the airflow to be
reduced
to 80% of normal
allowing
greater
humidity
control.
Humidistats
are preferred but an outdoor thermostat
can be used
but can only be set based on temperature.
Suggested
starting
point is 85 °F, but this will vary depending
on several factors.
The control must be wired differently
on air conditioners
and heat
pumps.
On air conditioners
connect
to Y and H (Dehum)
terminals,
ref Figure 7.

HEAT PUMPS ONLY: Heat pumps must use only the outdoor
thermostat, because it is powered instead of just performing a
switching function. This allows it to be out of the circuit when
continuous circulation is desired, which is required for the system
to operate on Fan Only for circulation, which is 60% airflow. On
heat pumps connect to Y and H (Dehum) terminals, and C and O
to power the outdoor thermostat, ref Figure 8.

The heater elements are turned on in increments.
Refer to Heater
Staging Table in the Heater installation
Manual. In addition on
heaters larger than 5KW, the heat can be staged (1 st & 2nd) either
through an indoor thermostat
or by using an outdoor thermostat.
This satisfies
staging requirements
imposed
by some electric
utilities on heaters larger than 6 kilowatts.

For proper system operation,
the air flow through the indoor coil
should be between 350 and 450 cfm per ton of cooling capacity.

by measuring the
