Ruud RA15AY representative manufacturer family image. Cabinet size and appearance vary by full model; use the actual drawing for the job.

Plan the equipment around the job

Keep the factory option in the model number.

The carried models below include the LHP suffix. Ruud lists these high/low-pressure-control variants separately from the base models, so keep the complete identifier through the quote and order.

01 / Full model

Retain the LHP suffix

Record the exact factory-option model shown in the chart and shop. The nominal size alone does not identify the ordered configuration.

02 / System rating

Quote the matched package

Ruud lists family efficiencies up to 16 SEER2 / 13 EER2. Establish the actual indoor coil or air handler and certified combination before assigning a rating to the job.

03 / Access and fit

Check the cabinet before the pad

The selected models range from 25 to 45 inches in operating height. Review the exact drawing, airflow/service clearances and piping route for the proposed location.

Use the full model, electrical phase and equipment nameplate. MCA and overcurrent values are manufacturer references; installation and conductor/protection selection must follow the applicable manufacturer instructions and requirements.
The listed models are equipment references supported by dated carried-model records, not a live inventory feed. Confirm current availability and contractor pricing before ordering.
The current A22-347 Rev. 4 model-identification table lists all six selected LHP models. General dimensions and electrical values are taken from the matching capacity and single-phase rows.

“Up to 16 SEER2” is a family limit, not every model’s rating.

The manufacturer specification lists RA15AY efficiencies up to 16 SEER2 / 13 EER2. The actual equipment combination, airflow and installation determine the applicable listed reference; preserve the full LHP model and indoor-unit identity when checking AHRI.

Search by the full outdoor model, then verify every listed component and the current official certificate. A matching brand or nominal size is not an approved system.

Read it. Save it. Bring it to the job.
