■Product Features
This Mini tankless electric water heater differs from a conventional storage type mini water heaters. It doesn’t store
hot water. Instead, water is heated instantaneously as it flows through the unit. The powerful heating elements are
activated by a flow switch as water is drawn from a hot water faucet connected to the appliance. The advantage
mini tankless water heater has greater energy efficiency than storage type water heaters as it only heats the water
when you demand it. The units are incorporated with multi-safety devices and will continuously supply hot water as
long as the faucet is open.
The Advantage mini tankless water heater has the following features.
1. Tankless, instantaneous heating for on demand hot water, No pre-heating. No stand-by heating loss.
energy-saving.
2. High strength ABS splash proof casing, stainless steel heating element.
3. Compact appearance and unlimited supply of hot water.
4. Easy installation, heater can be installed above or under sink.
5. Easy operation, the heater provides hot water with constant temperature.
6. Micro-computer control, using patented heating technology. Water is completely separated from electricity by
multi-layers of composite nano insulation material.
7. Over temperature protection: when the outlet water temp. reaches or over 60°C, the appliance will shut down,
it will re-start automatically while temp. drops to operating temperature range.
8. There is a built-in pressure relief valve at the water outlet to prevent explosion.

the setting temperature will be up 1C/1F. When up to 55c/131F, it will begin from 30C/86F recycled after next press. The
default temperature is 55°C/131F.
Press continued 3 seconds, the setting temperature will be setup among 100F （38C）， 107F（42C）， 131F
（55C）recycled.
6--- Press to convert the temperature display between fahrenheit degree and degree celsius.
Press continued 3 seconds to convert the temperature display ( numerals) between upside mounting and upside
down mounting.
7--- There is overheat production function for the appliance, if the outlet temperature reaches 60°C, the appliance will
automatically decrease the power level, only after the hot water temp. drops to 55°C, the unit will start to work again. In
this state, you should reduce the setting temperature.
8--- There is real-time leakage detection function, if there is a leak, the appliance will stop working automatically.
9--- There is a built-in pressure relief valve at the water outlet.When the pressure in the heating element is over 1.2Mpa,
the pressure relief valve will open and relieve the pressure.
10--- Please check hot water with hand before you taking a operation to avoid scalding.
If the unit is not being used in winter, drain out water completely so that the heater will not freeze.
Please periodically clean inlet strainer and the outlet taps or shower head to keep water flowing freely.
