• Supply circuit protective devices may be fuses or
“HACR” type circuit breakers.
• Largest motor load is included in single circuit.
• If non-standard fuse size is specified, use the next
larger fuse size.
• J Voltage (230V) single-phase air handler is
designed to be used with single or three phase 230
volt power. In the case of connecting 3-phase
power to the air handler terminal block, bring only
two leads to the terminal block. Cap, insulate and
fully secure the third lead.
• The air handlers are shipped from the factory with
the proper indoor coil installed, and cannot be
ordered without a coil.

Airflow performance data is based on cooling performance
with a coil and 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.

208V/240V Airflow Performance Data—RF1P (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.
• 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 with maximum heater allowed for each model.

208V/240V Airflow Performance Data—RF1T (X-13 (ECM) Motor)
Notes: X-13 motor speed changes.
All X-13 motors have 5 speed taps. Speed tap 1 is for continuous fan. Speed tap 2 (low static) and speed tap 3 (high static) are for lower tonnage. Speed tap 4 (low
static) and speed tap 5 (high static) are for higher tonnage.
X-13 air handlers are always shipped from factory at speed tap 5. To change to 1.5-ton or 2.5-ton airflow, move the blue wire to speed tap 2 or 3 on the
X-13 motor. The low static speed tap 2 (lower tonnage) and 4 (higher tonnage) are used for external static below 0.5" WC. The high static speed tap 3 (lower tonnage)
and 5 (higher tonnage) are used for external static exceeding 0.5" WC. Move the blue wire to the appropriate speed tap as required by the application needs.
• The airflow for continuous fan (speed tap 1) is 50% of the speed tap 4 airflow.
• The above airflow table lists the airflow information for air handlers with maximum heater allowed for each model.
