RH1T/RH2T- Series Constant Torque Motor (ECM) Efficiencies up to 16 SEER

• RH1T/RH2T feature a Constant Torque motor (ECM) which provides enhanced SEER performance with most Rheem out-door units.

• Versatile 4-way convertible design for upflow, downflow, horizontal left and horizontal right applications.

• Factory-installed indoor coil.

• Sturdy cabinet construction with 1.0 inch [25.4 mm] of foil faced insulation for excellent sound and insulating characteristics.

• Field-installed auxiliary electric heater kits provide exact heat for indoor comfort. Kits include circuit breakers which meet U.L. and cUL requirements for service disconnect.

• 11/2 ton [5.3 kW] through 5 ton [17.6 kW] models are between 421/2 to 57 inches [1080 to 1448 mm] tall and 22 inches [559 mm] deep.

• All models meet or exceed 330 to 400 CFM [156 to 189 L/s] per ton at .3 inches [.7 kPa] of external static pressure.

• Enhanced airflow up to .7" external static pressure.

• Evaporator is constructed of aluminum fins bonded to inter-nally grooved aluminum tubing.

• Suitable for application in mobile homes.

• Cabinet air leakage less than 2.0% at 1.0 inch H2O when tested in accordance with ASHRAE Standard 193.

Airflow Performance Data RH1T/RH2T Series

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 oper-ation within the minimum and maximum limits shown in table below for both cooling and electric heat operation. For opti-mum 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.

Motor Speed From

Factory

Notes: Constant Torque motor speed changes.

All Constant Torque 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.

Constant Torque air handlers are always shipped from factory at Speed tab 5, except for -4824, which is set at Speed tab 3. For instance, (-)H1T-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 Constant Torque 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)

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)

Electrical Data – With Electric Heat RH1T 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.

* Blower motors are all single phase motors.

• ? Heater Kit Connection Type A = Breaker B = Terminal Block C = Pullout Disconnect ➀ D Voltage = 480 Volts.

*Values only. No single point kit available.

NOTES:

• Electric heater BTUH - (heater watts + motor watts) x 3.414 (see airflow table for motor watts.)

• Supply circuit protective devices may be fuses 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.

• Heater loads are balanced on 3 phase models with 3 or 6 heaters only.

• 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 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 480V electrical heaters on 208/240V air handlers.

• 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.
