Undersink 277 V tankless heater

The Chronomite CM-15L/277 110F is an electric tankless water heater designed for undersink installation in commercial and residential settings. It operates on a 277 V AC single-phase supply and delivers hot water on demand without a storage tank.

Installation and activation

The unit measures 6.25 in high, 9.63 in wide and 2.75 in deep with a 3/8 in cold inlet, allowing it to fit in tight cabinet spaces. It requires a minimum flow of 0.2 gpm to activate, so very low-flow fixtures may not trigger heating. A 15 A circuit is needed to support the 4,150 W power draw.

Temperature and flow limits

The heater provides a maximum flow rate of 1 gpm with outlet temperatures fixed between 110 °F and 160 °F. The thermostat is not adjustable, so the temperature range cannot be altered on site. It is intended for indoor use only and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How can I confirm the heater is operating correctly once installed?

Verify that water reaches the set 110 °F minimum or up to 160 °F maximum at the tap and that the unit draws the rated 15 A at 277 V AC when flow exceeds 0.2 gpm.

What comes in the box and what must I supply separately?

The heater itself is included; you must provide a 277 V AC single-phase circuit rated for 15 A, 3/8 in cold-water supply fittings and a suitable indoor mounting location.

Which voltage and temperature version should I select for a commercial hand-wash station?

Choose the 277 V AC model with a 110 °F to 160 °F delivery range and 1 gpm maximum flow to match typical undersink commercial requirements.
