Undersink electric tankless heater

The Chronomite Instant-Flow Micro CM-30L/120 is a compact electric tankless water heater designed for undersink installation. It operates on a 120V AC single-phase supply and draws 30 A at 3600 W. The unit delivers a fixed outlet temperature of 110 Degrees F and activates at a minimum flow of .2 gpm up to a maximum of 2 gpm.

Installers needing a single-point hot water source

This heater suits commercial or residential sites that require instant hot water at a single fixture such as a lavatory or break-room sink. The fixed 110 Degrees F output and 2 gpm limit mean it cannot serve high-demand fixtures, multiple outlets or applications needing adjustable temperature. Buyers who need higher flow, variable temperature or whole-house coverage should look at larger capacity units.

Compression inlet and 10 AWG cord included

The package provides a 3/8 in compression cold-water inlet fitting for direct plumbing connection. A 10 AWG power cord is also supplied, allowing the 30 A load to be wired without sourcing separate conductors. These bundled items reduce installation time and ensure the electrical and plumbing connections meet the unit's specifications.

Questions about this item

Does the CM-30L/120 need a dedicated 30 A circuit and 10 AWG wiring to operate?

Yes, the unit draws 30 A at 120 V and the factory cord uses 10 AWG conductors, so a dedicated 30 A branch circuit with matching wire gauge is required.

Can the 3/8 in compression cold inlet connect directly to standard 1/2 in copper supply lines?

No, the heater’s cold inlet is a 3/8 in compression fitting; a 3/8 in to 1/2 in adapter or transition fitting is needed to join typical 1/2 in copper or PEX supply lines.

How can I confirm the heater is delivering water at the rated 110 °F after installation?

Run a tap until flow exceeds 0.2 gpm, then measure the outlet temperature with a thermometer; it should read 110 °F because the thermostat is fixed at that temperature.
