Copeland Comfort Control (Alco) 065410 Moisture Indicator

The Copeland Comfort Control (Alco) 065410 Moisture Indicator, specifically known as the HMI-1TT7, is a high-performance hermetic sight glass engineered for rigorous HVAC and refrigeration duty. Designed as the direct replacement for the legacy 048815 model, this indicator features a 7/8" ODF sweat connection for simplified brazing into the liquid line. It is fully compatible with a wide range of refrigerants, including CFC, HCFC, and HFC blends, and is rated for a maximum working pressure of 680 PSI. The hermetic moisture indicator provides technicians with instant visual verification of refrigerant chemistry and moisture levels, protecting critical system components from acid formation and chemical breakdown. Its robust construction ensures long-term leak integrity in high-pressure environments, making it a staple for maintaining industrial and commercial cooling equipment.

• Universal Compatibility: Optimized for use with standard refrigerants and oils in diverse refrigeration profiles.
• High Pressure Rating: Rated for 680 PSI, ensuring safety and durability in R-410A and other high-pressure applications.
• Direct OEM Replacement: Replaces the 048815 effortlessly, maintaining original equipment configurations.
• Clear Diagnostics: Large viewing window provides a high-contrast indication of moisture levels to prevent compressor failure.
• Hermetic Construction: Eliminates traditional glass-to-metal leakage joints for superior vacuum and pressure performance.

Is the HMI-1TT7 compatible with R-410A systems?
Yes, with a maximum working pressure of 680 PSI, this 7/8" sweat moisture indicator is fully rated for the high-side pressures typically found in R-410A HVAC systems.

Can this unit detect moisture in both liquid and suction lines?
While technically possible, moisture indicators are most effective when installed in the liquid line to provide an accurate reading of the refrigerant's state before it reaches the expansion device.

Does this indicator include a color-change chart?
The internal element provides a distinct color change based on moisture content (Dry vs. Wet); however, technicians should always refer to the specific refrigerant saturation levels at the current system temperature for precise diagnostics.
