Piping Size

For the correct tubing size, follow the specification for the condenser/heat pump.

WARNING

THIS COIL IS SHIPPED UNDER PRESSURE. FOLLOW THESE INSTRUCTIONS TO PREVENT INJURY (SEE

FIGURES 1 AND 2).

Evaporator Coil Metering Devices

Flowrater Models (ARUF and ARPF)

For most installations no change to the flowrater orifice is required. In mix-matched applications (condenser/heat pump is a different tonnage than the air handler), a different flowrater orifice may be required. See the Goodman piston kit chart PKC-00 or latest revision. Consult your local distributor for the details regarding mix-matched orifice sizing.

1.Loosen the 13/16 nut 1 TURN ONLY. No pressure loss indicates possible leak.

2.Remove the nut and discard the black or brass cap.

3.Remove the check piston to verify it is correct. See piston kit chart in instructions.

4.Use a tube cutter to remove the spin closure on the suction line.

5.Remove the tailpiece clamped to the exterior.

6.Slide the 13/16 nut into position. Braze tailpiece to the liquid tube.

7.Insert the suction line into the connection, slide the insulation and the rubber grommet at least 18" away from the braze joint.

8.AFTER THE TAILPIECE HAS COOLED, position the white Teflon seal and hand tighten the nut.

9.Torque the 13/16 nut to 20-30 ft-lbs. [2.77-4.15 meter kg].

10.Replace suction line grommet and insulation.

IMPORTANT NOTE: In order to prevent damage to the sensing bulb, it is not permanently installed in the factory. This bulb is to be removed prior to brazing. Place in proper location after braze joint has cooled (Figure 3).

1.Loosen the 13/16 nut 1 TURN ONLY. No pressure loss indicates possible leak.

2.Remove the nut and discard the black or brass cap.

3.Remove large front panel and remove sensing bulb from suction manifold. TO PREVENT DAMAGE TO SENSING BULB, ENSURE BULB IS NOT NEAR FLAME OR IN CONTACT WITH SUCTION LINE OR MANIFOLD DURING BRAZING.

4.Use a tube cutter to remove the spin closure on the suction line.

5.Remove the tailpiece clamped to the exterior.

6.Slide the 13/16 nut into position (Figure 1). Braze tailpiece to liquid tube.

7.Insert the suction line into the connection, slide the insulation and the rubber grommet at least 18" away from the braze joint.

8.AFTER THE TAILPIECE HAS COOLED, position the white Teflon seal and hand tighten the nut.

9.Torque the 13/16 nut to 20-30 ft-lbs. [2.77-4.15 meter kg].

10.Replace sensing bulb to horizontal portion of suction line (Figure 3) just inside cabinet. Place bulb parallel with suction line in the 10 o’clock position. If 10 o’clock position is inaccessible, place in the 2 o’clock position. Secure bulb to line with strapping provided in literature envelope. Insulate sensing bulb to line with self- adhesive insulation provided in envelope.

11.Replace access panel, suction line grommet, and insulation.

AEPT, ARPF, ARPT specifications

Goodman Manufacturing is a leading name in the air conditioning and heating industry, known for its commitment to high-quality products and innovative technologies. Among its esteemed lineup are the AEPT, ARPT, and ARPF series of heat pumps, which have garnered attention for their efficiency, reliability, and advanced features.

The Goodman AEPT series is designed for high efficiency and performance. These heat pumps utilize scroll compressor technology, which not only enhances their energy efficiency but also provides quieter operation compared to traditional compressors. With a SEER (Seasonal Energy Efficiency Ratio) rating that often exceeds 15, the AEPT series allows homeowners to significantly reduce their energy costs while enjoying optimal comfort throughout the year. Additionally, these units come equipped with a weather-resistant cabinet designed to withstand harsh outdoor conditions, ensuring durability and longevity.

The ARPT series takes innovation a step further by incorporating advanced refrigerant technology. Using R-410A refrigerant, these heat pumps operate with minimal environmental impact while providing robust heating and cooling capabilities. The ARPT units are equipped with a multi-speed ECM (Electronically Commutated Motor) blower motor that allows for improved airflow and enhanced humidity control, leading to a more comfortable indoor environment. The smart design of the ARPT series also emphasizes ease of installation and service, making it a preferred choice among HVAC professionals.

Finally, the Goodman ARPF series is engineered for versatility and performance in various climates. With a focus on user-friendly features, these heat pumps are designed to operate efficiently in both heating and cooling modes. The ARPF models come with digital thermostats that provide precise temperature control, ensuring that homes remain comfortable regardless of external weather conditions. Moreover, their advanced defrost controls allow for enhanced performance in colder climates, ensuring that homeowners can rely on their heat pumps even during extreme temperatures.

In summary, the Goodman AEPT, ARPT, and ARPF heat pump series showcase cutting-edge technology and innovative features focused on energy efficiency, environmental responsibility, and user comfort. These units not only promise durability and high performance but also ease of installation and maintenance, making them a smart investment for homeowners seeking reliable climate control solutions.
