A standard 120v electrical outlet is required under the sink. If possible, use a separate circuit dedicated to your Hot
Tank.
It is recommended that a separate circuit serving only your electronic instant hot water appliance be provided
or use an outlet that can be turned on/o by a switch. This electronic instant hot water appliance is equipped with a
power supply cord with a power plug. To minimise possible shock hazard, the cord must be plugged into mang,
ground-type outlet, grounded in accordance with all naonal and local codes and ordinances. If a socket outlet is not
available, it is the responsibility and obligaon of the customer to have a properly grounded outlet installed by a
qualied electrician.
Water Supply Requirements
If local codes permit, the instant hot water Dispenser feed line should be connected to the hot and cold water supply
line using an isolaon valve or another means for providing the hot and cold water to the Dispenser. IMPORTANT: If
local codes do not permit the use of isolaon valves, special feed valves can be obtained from your local plumbing
supply distributor. f the water is mixed with impurity, ironing chips, grains of sand, and so on, the pipes of the electron-
ic instant hot water appliance and Dispenser will be blocked and will void the guarantee.
Environment requirement
Don't install the electronic instant hot water appliance outdoors or in a locaon that may fall below 32F, otherwise the
pipes and the Dispenser and tank will be frozen and there will be serious safety trouble, possible bodily -injury, acci-
dents and damaged caused and the guarantee will be void. It's forbidden to wash the electronic instant hot water
appliance with water directly. The installaon environment should be venlated, with protecon from the direct sun-
shine. When installing the electronic instant hot water appliance, provide approximately 10cm to 15cm (4 -5 ½”) of air
space on the sides of the unit for air circulaon and approximately 2.5cm (1”) from the mounng wall. The environ-
ment humidity should be in the range of 10% to 60%. Be sure there is no dew.
Instant Hot Water Dispenser Informaon
Connecng a standard Dispenser may cause injury and will damage the electronic instant hot water appliance and void
