Steam Fired Instantaneous Water Heater | One-Way Method
Hot Water Supply System Steam Fired Instantaneous Water Heater | One-Way Method
LMG1 | Electrical safety shutoff system
Safety additional device for LM15
Features/Applications
Features
Product Overview
This is a system product that detects hot water supplied from the LM15 and opens an electromagnetic valve for steam (product on the market), and closes this valve when no hot water is being supplied.
Safety-focused design
As well as reducing the load on the body of the water heater, it also prevents the backflow of hot water in the event of a fault in the water heater. It detects when the supply of hot water is halted and automatically shuts off the supply of steam.
Passed the test of effect to water quality that meet JIS
Typical applications
Mitigation of abnormal temperature increase and prevention of hot water backflow to cold water lines in the event of a fault in an internal component in the water heater.

● Electromagnetic valve required (available separately)
● Electromagnetic valves for steam
When selecting an electromagnetic valve, please choose a product that conforms to the following specifications.
For use with: Steam Max. operating pressure: 0,3MPa (43.5psig)or more Max. operating temperature: 143℃ (289℉) or more
Cv value: 2.0 or more Voltage rating: 100VA or less Operation: On when power is on

●Precautions
*If the way you intend to use the product involves physical contact with hot water, please be sure to separately install a thermostatic mixing valve (available on the market) in order to prevent scalding.
*Do not use for shower systems.
*It is not recommended that water supplied using this product be directly used for drinking water.
*Do not use with vinyl chloride pipes or lining pipes
*Ensure that the pressure differential between the steam supply pressure and the condensate discharge part is at least 0,03MPa (4.4psig). If back pressure is applied to the condensate discharge pipe, the maximum hot water supply rate drops.
*If the water supplied to a hot water device contains much silica or calcium, this may cause accelerated deterioration in the performance of the main components.
*Before use, be sure to perform an inspection in accordance with the procedure in the “Using Water Heaters Safely” document included with this product.
