Operating Instructions for the Home Owner
This electric water heater is designed to supply hot water for a house or apartment. Unlike a
conventional tank storage water heater, this unit is a tankless water heater that does not store hot
water. However, once you begin using the system, you will find it operates much like a conventional
tank system.
Tankless systems deliver hot water instantaneously on demand. Since a tankless system does not
waste energy continually heating water that is idly sitting and losing heat in a storage tank, it provides
greater energy efficiency than a conventional system.
With your new system, as soon as you turn on a hot water faucet, the demand for hot water is
detected, and high power heating elements are activated. Sensors continually monitor water flow
rate and incoming and outgoing temperature, and transmit data to the system controller, which
determines the exact amount of power required by heating elements to reach the set temperature.
It is important to keep in mind that all tankless water heaters are subject to a maximum flow rate. If
this flow rate is exceeded, the heater will not be capable of fully heating water.
Also keep in mind that conventional tank heaters are set to high temperatures to prevent running
out of hot water quickly, and thus a large amount of cold water needs to be mixed in to reach a
comfortable level for washing and showering. Since this unit heats water on demand, it is designed
to heat to a lower temperature. This means you only need to mix in a small amount of cold water,
or none at all.
Your hot water supply may also be affected by the incoming water temperature. During winter, if
incoming water temperature is very cold, you might not be able to run multiple hot water outlets at
the same time. However, you can run showers back-to-back without having to wait for water to heat.
Setting the Output Water Temperature
To set the temperature, first turn on a hot water faucet and allow water to run through the heater.
The digital display lights up and shows the current temperature setting.
To increase or lower the temperature setting, press the UP or DOWN button.
Temperature can be set to a level from 90°F to 122°F (30°C to 50°C).
A comfortable temperature for bathing and showering is between 98°F and 105°F (37°C to 41°C).
The recommended temperature setting is 118°F (48°C), which will deliver hot water for all household
needs at a maximum water flow rate. A higher temperature setting is not recommended, as it can
cause serious scalding injuries to children and elderly persons. Higher temperatures also produce
more scale buildup in water heating devices.
