Airflow Performance
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.

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—RHBL (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.

*Blower motors are all single phase motors.
RHAL/RHBL Electrical Data – with Electric Heat
Installation of the U.L. Listed original equipment manufacturer provided heater kits listed in the table below is recommended for all
auxiliary heating requirements.
• Electric heater BTUH - (heater watts + motor watts) x 3.414 (see airflow table for motor watts.)
• 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.
• Largest motor load is included in single circuit or circuit 1 of multiple circuits.
• No electrical heating elements are permitted to be used with A Voltage (115V) air handler.
• 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 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 480 volts electrical heaters on 230 volts air handler.
Electrical Wiring:
Power Wiring
• Field wiring must comply with the National Electrical Code
(C.E.C. in Canada) and any applicable local ordinance.
• Supply wiring must be 75°C minimum copper conductors only.
• See electrical data for product Ampacity rating and Circuit
Protector requirement.
Grounding
• This product must be sufficiently grounded in accordance with
