CondensateDrainConnections

The unit is provided with 3/4" National Pipe Thread (NPT) con-
densate drains. (Figure 1). Any drain can be used as a primary or

secondary drain depending on the fitting used. Condensate drain

lines should be installed in a manner that does not obstruct ac-

cess to the filter.
There is a secondary drain fitting supplied with the unit that will

convert any of the primary condensate drain connections into a
secondary drain connection. This fitting should be installed in any

of the primary drain connections to convert itto a secondary drain.

LowVoltage Control Connections

The 24 volt power supply is provided by an internally wired low
voltage transformer which is standard on all models. If power

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

Field supplied low voltage wiring can enter the unit on the top left

hand corner* or the left hand side panel. When using the left hand
side panel entrance, the low voltage wiring must be fed through

the entrance hole in the bottom of the blower deck into the control
area.

Install the strain relief bushing (supplied with unit) in the selected

hole and a hole plug (supplied with unit) in the unused hole.
Connect the field wiring at the screw terminals of the control

board. Refer to Figure 9.

Keep the low voltage wiring as short as possible inside the control

box.

Adding Humidistator OutdoorThermostat

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 Dehum terminals H,

ref Figure 10.

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 Dehum terminals H, and C and O to

power the outdoor thermostat, ref Figure 11.

ElectricHeaterStaging

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.

A control signal (24V) from Wl on the Indoor T'stat to Wl on the
control board energizes the 1st stage of heat. A control signal

(24V) to W2 on the control board energizes the second stage of
electric heat. To turn ON both stages at the same time, using one

control signal, W1 and W2 are jumpered together.

If the indoor thermostat does not have staging capabilities,
accessory electronic outdoor thermostats are available that will
control two stages of electric heat.

MotorSpeedsandAirflow

See Figure 12 and Page 8.

The motor speed can be set on one of eight speeds and the air
flow will adjust between 60%, 80% and 100% depending on

settings. Time ON / OFF settings can also be adjusted.

Determine coil static pressure drop, consult coil manual and
measure duct system static pressure, then determine required

speed setting from blower charts.

For Cooling - Set switches 6, 7, and 8 on the motor end bell to
position 0 (off) or 1 (on) as specified on blower charts.

For Heating - Set switches 3, 4, and 5 on the motor end bell to
position 0 (off) or 1 (on) as specified on blower charts.

Set switches 1 and 2 to position 0 (off) or 1 (on) as specified in

Figure 12 to control Fan delay ON - OFF.

NOTE: Power must be completely OFF to unit any time
switch settings are changed or settings will not take effect.

Air Flow Check

For proper system operation, the air flow through the indoor coil

should be between 350 and 450 cfm per ton of cooling capacity.
The air flow through the unit can be determined by measuring the

external static pressure to the unit and selecting the motor speed
tap that will most closely provide the required air flow.

1. Set up to measure external static pressure at the supply
and return duct connections (Figure13).

2. Drill holes in the ducts for pressure taps, pitot tubes, or
other accurate pressure sensing devices.

Figure static Pressure Check

s.pply ___¢)

/nedtI°rn

3. Connect these taps to a level inclined manometer or draft
gauge.

4. Ensure the coil and filter are clean, and all the registers are
open.

5. Determine the external static pressure with the blower
operating.

6. Refer to the Air Flow Charts, pages 9 & 10 to find the Dip

Switch Speed setting that will most closely provide the
required air flow for the system.

7. Refer to Motor Speeds and Airflow in these instructions if
the speed is to be changed.

8. Recheck the external static pressure with the new setting,
and confirm speed switch selection.

TemperatureRiseCheck

Temperature rise is the difference between the supply and return
air temperatures.

NOTE: The temperature rise can be adjusted by changing the
heating speed tap at the unit's blower terminal block.

A temperature rise greater than 60 OF (33.3 °C) is not
recommended.

1. To check the temperature rise through the unit, place
thermometers in the supply and return air ducts as close to

the unit as possible.

2. Open ALL registers and duct dampers.

3. Set thermostat Heat-Coo! selector to HEAT.

4. Set the thermostat temperature setting as high as it wil! go.

5. Turn electric power ON.

6. Operate unit AT LEAST 5 minutes, then check
temperature rise.

NOTE: The maximum outlet air temperature for all models

is 200 OF (93.3 °C).

7. Set thermostat to normal temperature setting.

8. Turn electric power OFE

9. Be sure to seal al! holes in ducts if any were created during
this process.

Maintenance

Filters

Filters must be cleaned when they become dirty. Inspect at least

once per month. The frequency of cleaning depends upon the
hours of operation and the local atmospheric conditions. Clean

filters keep unit efficiency high.

Lubrication

The bearings of the blower motor are permanently lubricated.

Condensate Drains

During the cooling season check the condensate drain lines to be
sure that condensate is flowing from the primary drain but not
from the secondary drain. If condensate ever flows from the

secondary drain the unit should be promptly shut off and the
condensate pan and drains cleaned to insure a free flowing

primary drain.
