M48E36AR – 4 Ton Manufactured Housing Uncased Coil / Mobile Home

M48E36AR 4 Ton Manufactured Housing Coil Overview

The M48E36AR 4 Ton evaporator coil is an ADP M Series uncased indoor coil designed for manufactured and mobile home HVAC applications. Its model nomenclature identifies a nominal 48,000 BTU capacity, copper slab, R-454B non-bleed heat pump and air-conditioning TXV, and factory-installed refrigerant detection system controller and sensor.

This product is an indoor evaporator coil only. It does not include an outdoor air conditioner, heat pump, furnace, blower, coil cabinet, thermostat, refrigerant line set, or complete HVAC system. The coil must be paired with compatible indoor and outdoor equipment selected for the application.

System Compatibility

The M48E36AR 4 Ton coil is designed for use with compatible manufactured housing electric furnaces in downflow or approved upflow arrangements and compatible manufactured housing gas furnaces in downflow applications. Final orientation depends on the furnace, cabinet, drain-pan arrangement, airflow direction, and manufacturer installation requirements.

A nominal four-ton designation does not confirm compatibility with every four-ton condenser or heat pump. The exact outdoor-unit model, furnace or blower, refrigerant, TXV, airflow, refrigerant charge, line sizes, and AHRI match must be verified before ordering.

The installed system’s SEER2, EER2, HSPF2, and certified cooling or heating capacities are determined by the complete matched equipment combination. The M48E36AR 4 Ton coil does not have an independent SEER2 rating.

R-454B Refrigerant Information

The M48E36AR 4 Ton coil is configured for R-454B refrigerant. R-454B is classified as an A2L refrigerant and requires compatible equipment, approved tools, appropriate ventilation, leak-testing procedures, and trained service personnel.

The coil must only be connected to equipment using the refrigerant shown on its nameplate. R-410A, R-32, or another refrigerant must not be substituted for R-454B in this specific factory configuration.

The factory-installed refrigerant detection system controller and sensor are part of the equipment’s A2L safety configuration. The detection system must remain powered, connected, positioned, and commissioned according to the ADP instructions and the requirements of the complete HVAC system.

Installation Requirements

The M48E36AR 4 Ton evaporator coil requires professional installation. Before installation, inspect the coil for shipping damage and verify that the factory dry-air holding charge is present. The absence of pressure does not independently confirm a leak, so the coil must be properly leak tested.

The coil must be level or pitched slightly toward the condensate drain. Downflow applications require an airtight seal between the coil cabinet and furnace or blower cabinet. Refrigerant lines, drain connections, TXV components, detection-system wiring, minimum conditioned-area requirements, and service clearances must follow the current ADP installation instructions.

Improper airflow can cause coil freezing, water carryover, reduced capacity, and system damage. The installer must configure airflow according to the approved equipment match rather than relying only on the coil’s nominal tonnage.

Warranty and Documentation

ADP documentation references a five-year no-hassle warranty with a ten-year limited warranty available for eligible M Series coils. Actual coverage can depend on registration, installation, application, ownership, and current warranty terms. Verify the M48E36AR 4 Ton warranty requirements before purchase and retain the invoice, model number, serial number, and installation records.
