• Supply circuit protective devices may be fuses or
“HACR” type circuit breakers.
• Largest motor load is included in single circuit
and multiple 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.
• The air handlers do not have an internal filter
rack. An external filter rack or other means of
filtration is required.

• 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)

115V/208V/240V/460V Airflow Performance Data—RHLL (X-13 (ECM) Motor)
Notes: X-13 (ECM) motor speed changes.
All X-13 (ECM) motors have 5 speed tabs. Speed tab 1 is for continuous fan. Speed tab 2 (low static) and Speed tab 3 (high static) are for lower tonnage.
Speed tab 4 (low static) and Speed tab 5 (high static) are for higher tonnage.
X-13 (ECM) air handlers are always shipped from factory at Speed tab 5, except for -4824, which is set at Speed tab 3. For instance, RHLL-HM2417JA is
always shipped at high static 2-ton airflow (Speed tab 5). To change to 1.5-ton airflow, move the blue wire to Speed tab 2 or 3 on the X-13 (ECM) motor.
The low static Speed tab 2 (lower tonnage) and 4 (higher tonnage) are used for external static below 0.5" WC. The high static Speed tab 3 (lower tonnage)
and 5 (higher tonnage) are used for external static exceeding 0.5" WC. Move the blue wire to the appropriate Speed tab as required by the application needs.
• The airflow for continuous fan (Speed tab 1) is always set at 50% of the Speed tab 4.
• 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/240V/460V Airflow Performance Data—RHLL (X-13 (ECM) Motor) (con’t.)
Notes: X-13 (ECM) motor speed changes.
All X-13 (ECM) motors have 5 speed tabs. Speed tab 1 is for continuous fan. Speed tab 2 (low static) and Speed tab 3 (high static) are for lower tonnage.
Speed tab 4 (low static) and Speed tab 5 (high static) are for higher tonnage.
X-13 (ECM) air handlers are always shipped from factory at Speed tab 5, except for -4824, which is set at Speed tab 3. For instance, RHLL-HM2417JA is
always shipped at high static 2-ton airflow (Speed tab 5). To change to 1.5-ton airflow, move the blue wire to Speed tab 2 or 3 on the X-13 (ECM) motor.
The low static Speed tab 2 (lower tonnage) and 4 (higher tonnage) are used for external static below 0.5" WC. The high static Speed tab 3 (lower tonnage)
and 5 (higher tonnage) are used for external static exceeding 0.5" WC. Move the blue wire to the appropriate Speed tab as required by the application needs.
• The airflow for continuous fan (Speed tab 1) is always set at 50% of the Speed tab 4.
• 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)

Installation of the U.L. Listed original equipment manufacturer provided heater kits listed in the table below is recommended for all
auxiliary heating requirements.
* Values only. No single point kit available.
• Supply circuit protective devices may be fused or “HACR” type circuit breakers.
• If non-standard fuse size is specified, use next size larger standard fuse size.
• If the kit is listed under both single and multiple circuits, the kit is shipped from factory as
multiple circuits. For single phase application, Jumper bar kit RXBJ-A21 and RXBJ-A31 can be
used to convert multiple circuits to a single supply circuit. Refer to Accessory Section for details.
• Largest motor load is included in single circuit or circuit 1 of multiple circuit.
• Heater loads are balanced on 3 PH. models with 3 or 6 heaters only.
• Electric heater BTUH - (heater watts + motor watts) x 3.414 (see airflow table for motor watts.)
• No electrical heating elements are permitted to be used with “A” voltage (115V) air handler.
• J voltage (208/240V) single phase air handler is designed to be used with single or three phase
208/240V electric heaters. In the case of connecting 3 phase power to air handler terminal block
without the heater, bring only two leads to terminal block. Cap, insulate and fully secure the
third lead.
• Do not use 480V electrical heaters on 208/240V air handlers.
• Do not use 208/240V electrical heaters on 480V air handlers.
