Aspen CM48E4G-177L-006 Uncased Evaporator Coil 3.5-4 Ton

Product Description

The ASPEN CM48E4G-177L-006 is an uncased downflow evaporator coil rated at 48000 BTU/h (3.5-4 ton), engineered for use in manufactured home HVAC installations. It features rifled copper tubing and enhanced aluminum fins for efficient heat transfer, and is built with a 4-row coil configuration. The coil ships nitrogen-pressurized and sealed after immersion testing at 500 psi, confirming structural integrity before installation. A heavy-duty polypropylene drain pan, condensate drain elbow, flexible drain tubing, and a downflow plate kit are all included. This coil is installed by licensed HVAC technicians working in manufactured and mobile home applications.

This coil is designed for downflow installations in manufactured home furnace systems paired with air conditioner or heat pump equipment. Left-hand refrigerant and plumbing connections are standard on this unit. The suction line connection is 7/8 ODS and the liquid line is 3/8 ODS, appropriate for the 3.5-5 ton range. A liquid line Schrader valve is included for hiss-testing during commissioning. The 177L drain pan features a single left-hand 3/4 FPT drain connection. This coil is AHRI certifiable with all brands of air conditioner and heat pump systems and is ETL listed for use with R-22 and R-410A refrigerants when the proper metering device is installed.

Compatibility

Designed for downflow installations in manufactured and mobile home furnaces paired with air conditioner or heat pump systems. AHRI certifiable with all brands of air conditioner and heat pump equipment. ETL listed for use with R-22 and R-410A refrigerants when the appropriate metering device is used. A flow restrictor is included to serve as the metering device.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable local mechanical codes and EPA Section 608 refrigerant handling regulations. Shut down and lock out the electrical system and recover all refrigerant from the system before disconnecting refrigerant lines. Verify that the correct metering device is installed to maintain ETL listing compliance for the refrigerant type in use. Ensure the drain pan connection is properly trapped and routed per local plumbing codes before returning the system to service.
