Airflow Performance

Airflow performance data is based on cooling performance
with a coil and no filter in place. Select performance table for

appropriate unit size, voltage and number of electric heaters to
be used. Make sure external static applied to unit allows oper­ation within the minimum and maximum limits shown in table

below for both cooling and electric heat operation. For opti­mum blower performance, operate the unit in the .3 [8 mm] to
.7 inches [18 mm] W.C. external static range. Units with coils
should be applied with a minimum of .1 inch [3 mm] W.C.
external static range.

Notes: • All 208/240V PSC motors have voltage taps for 208 and 240 volts.

• All 208/240V PSC motors are shipped on high speed and 240 volts.

• If the application external static is less than 0.5" WC, adjust the motor speed to the low static speed as described below:

• Unplug the black motor wire off the relay on the control board and plug in the red motor wire.

• Replace the cap on the black motor wire.

• Voltage change (208/240V motors):

• Move the orange lead to transformer 208V tap from 240V tap. Replace the wire cap on 240V tap.

• Unplug the purple motor wire off the transformer and plug in the yellow motor wire.

• Replace the cap on the purple motor wire.

• The above airflow table lists the airflow information for air handlers without heater and air handler with maximum heater allowed for each model.

• The following formula can be used to calculate the approximate airflow, if a smaller (N kW) than the maximum heater kit is installed.
Approximate Airflow = Airflow without heater - (Airflow without heater - Airflow with maximum heater) x (N kW/maximum heater kW)

115V/208V/480V Airflow Performance Data—RHSL (PSC Motor)

Notes: • All 208/240V PSC motors have voltage taps for 208 and 240 volts.

• All 208/240V PSC motors are shipped on high speed and 240 volts.

• All 115V PSC motors are shipped on high speed.

• If the application external static is less than 0.5" WC, adjust the motor speed to
the low static speed as described below:

• Unplug the black motor wire off the relay on the control board and

plug in the red motor wire.

• Replace the cap on the black motor wire.

• Voltage change (208/240V motors):

• Move the orange lead to transformer 208V tap from 240V tap.

Replace the wire cap on 240V tap.

• Unplug the purple motor wire off the transformer and plug in the

yellow motor wire.

• Replace the cap on the purple motor wire.

• All 480V PSC motors are shipped on high speed.

• If the application external static is less than 0.5" WC, adjust the motor speed to
the low static speed as described below for 3-ton through 4-ton air handlers.

• Unplug the black motor wire off the relay and remove the cap from
the red motor wire.

• Plug the red motor wire to the relay and connect the black motor
wire with the yellow motor wire.

• For 5-ton air handler, unplug the black motor wire off the relay and plug in the red
motor wire, then cap the black motor wire. There is no yellow motor wire on 5-ton
air handler.

WARNING: Do not connect red motor wire with yellow motor wire in any circumstance on
480V PSC motors. Connecting red motor wire with yellow motor wire will result in
permanent motor damage.

• The above airflow table lists the airflow information for air handlers without heater and air
handler with maximum heater allowed for each model.

• The following formula can be used to calculate the approximate airflow, if a smaller (N kW)
than the maximum heater kit is installed. Approximate Airflow = Airflow without heater ­(Airflow without heater - Airflow with maximum heater) x (N kW/maximum heater kW)

Electrical Data – With Electric Heat

Installation of the U.L. Listed original equipment manufacturer provided heater kits listed in the following table is recommended for all
auxiliary heating requirements.

• Supply circuit protective devices may be fuses or “HACR” type circuit breakers.

• Largest motor load is included in single circuit and multiple circuit 1.

• If non-standard fuse size is specified, use next size larger standard fuse size.

• J Voltage (230V) single phase air handler is designed to be used with single or three phase 230 volt electric heaters. In the case of connecting 3-phase power to the air handler terminal block
without the heater, bring only two leads to the terminal block cap, insulate and fully secure the third lead.
