System Nomenclature and Model Identification
Goodman ARUF units use a structured model numbering system that encodes capacity, configuration, and series. The first digit indicates the heating capacity in kW, followed by a letter for the series (e.g., F for standard, G for advanced). The remaining digits specify the specific model and optional features.

3.1 Model Number Structure
Goodman’s ARUF series employs a concise alphanumeric scheme that conveys key performance and configuration data at a glance. The first digit represents the nominal heating capacity in kilowatts (kW), ranging from 3 to 25. For example, a “3” indicates a 3 kW unit, while a “25” denotes a 25 kW model. Immediately following this digit is a single letter that identifies the product line: “F” for the standard ARUF line, “G” for the advanced “FARUF” variant, and “S” for the supplemental “SS‑ARUF” models. This letter also signals the presence of additional features such as a supplemental heat‑pump kit or a specialized blower motor. The remaining two to three characters are a unique alphanumeric code that distinguishes individual models within the same capacity and series. This code often encodes the cabinet orientation (horizontal “H” or vertical “V”), the presence of a 3‑way valve (“3W”), or the type of heat‑kit (e.g., “K” for 3‑kW kit). For instance, the model number “25G3WK” can be decoded as a 25 kW, advanced series unit with a 3‑way valve and a 3‑kW heat kit. The structured format allows technicians to quickly identify the correct installation manual, wiring diagram, and accessory list by simply referencing the model number. All official Goodman documentation, including the ARUF Installation Manual PDF, lists the full model number on the first page, ensuring that installers and service personnel can cross‑reference the correct specifications and compliance data without confusion.
When searching the PDF repository, the model number appears in the header and in the table of contents. The manual includes a dedicated section that maps each model number to its corresponding heater kit size, airflow rating, and wiring diagram. This mapping is crucial for ensuring that the correct electrical supply and ductwork are specified. Additionally, Goodman’s online portal allows users to enter the model number to download the appropriate PDF, reducing the risk of installing an incompatible unit. The consistency of the numbering system also facilitates warranty registration, as the model number is required to verify the 10‑year parts warranty eligibility. By mastering the model number structure, technicians can streamline the installation process, avoid costly errors, and guarantee compliance with ASHRAE standards for cabinet leakage and airflow. This systematic approach is a hallmark of Goodman’s commitment to precision and customer support.

3.2 Recommended Accessories Overview
Goodman’s ARUF units are modular, and the installation manual PDF lists accessories that improve performance and simplify setup; Core additions include 3‑kW to 25‑kW electric heater kits, matched to the unit’s capacity for supplemental heat at low temperatures. Heater kits are installed behind the cabinet, and the manual details venting, wiring, and grounding.

Installation and Commissioning Guidelines
Follow the PDF’s step‑by‑step guide: mount the cabinet, secure the blower, connect the 120‑V circuit, test for leaks, and register the warranty. Verify airflow, check the thermostat, and perform a final leak test before commissioning. Ensure all connections are tight, and verify voltage before powering up.
5.1 Cabinet Mounting and Leak Testing
Begin by positioning the ARUF cabinet on a level, insulated surface, ensuring the back clearance matches the manufacturer’s 1‑inch minimum. Secure the unit with the supplied 3‑in. x 3‑in. screws, tightening in a criss‑cross pattern to distribute clamping force evenly. Use a torque wrench set to 20 ft‑lb to avoid over‑tightening, which can damage the cabinet frame. After mounting, attach the 120‑V power supply, verifying that the neutral and ground are correctly connected to the unit’s terminal block. Check the wiring diagram in the PDF to confirm the correct pin assignments for the 3‑phase or single‑phase configuration. Next, perform a leak test by applying a 1‑inch water pressure to the cabinet’s air inlet and outlet ports, as outlined in the manual. Use a calibrated pressure gauge and a small nozzle to apply the pressure for 30 seconds. The pressure should remain stable within ±0.1 in. H₂O; any drop indicates a leak. If a leak is detected, inspect the gasket seals, ensuring they are seated properly and free of debris. Replace any damaged gaskets and re‑test. Once the cabinet passes the leak test, install the evaporator coil onto the mounting track, aligning the coil’s centerline with the cabinet’s airflow path. Secure the coil with the provided fasteners, tightening to the manufacturer’s torque specifications. Finally, run a short power cycle, monitor the blower speed, and confirm that the thermostat registers the correct temperature. Document all steps in the installation log for warranty compliance. Verify all seals before final power up.
5.2 Drainage, Coil Setup, and Warranty Registration

After securing the cabinet, install the decaBDE‑free thermoplastic drain pan beneath the unit. Connect the primary drain line to the pan’s outlet, ensuring a 1‑inch slope toward the vent. Attach the secondary drain connection to the back of the cabinet, allowing an alternate path if the primary line becomes clogged. Next, mount the evaporator coil onto the cabinet’s built‑in track. Align the coil’s centerline with the airflow path, then secure it with the supplied fasteners; torque to the manufacturer’s specification to prevent overtightening. Verify that the coil’s mounting brackets are flush with the cabinet wall to avoid air leakage. Once the coil is in place, perform a water‑tightness check by running a small amount of water through the drain line and observing for leaks at the pan, secondary connection or coil mounting points. After confirming a leak‑free system, register the unit online within 60 days of installation to activate the 10‑year parts limited warranty. Registration is not required in California or Quebec, but all other regions must complete the process at the manufacturer’s website. Keep a copy of the registration confirmation in the installation log for future reference. Verify that the cabinet’s vent openings are clear of obstructions and that the unit’s airflow path is unobstructed. Use a calibrated pressure gauge to confirm cabinet air leakage remains below specified limits. Document all measurements and test results in the installation log for warranty verification. Follow local codes during installation. Verify cabinet clearance.
