5 Operation Instructions
The water heater has an adjustable thermostat to control water temperature. The hot
water for automatic dishwashers and washing machines can cause severe injury or death
from scalds. Temperature that causes injury varies from age of people and contact time.
Disabled persons are at higher risk of being scalded for slow reflection. Do not let children
use the faucet alone, or take bath or shower by themselves. Do not let children or the
disabled stay in the bathtub or under the spray nozzle alone.
Setting water heater temperature at 49

will decrease the risk of scald injury.
It shows the scald time for skins of most people in table 5.1. For a small amount of water
is heated repeatedly in short time resulting from it is used continually many times, water outlet
temperature can be higher than setting temperature by 11
ć
. On this condition, please adjust
the lower setting temperature to decrease the risk of being scalded.
