3. General
The tankless water heater differs from conventional storage type
water heaters in several ways. It does not store hot water. Instead,
water is heated instantaneously as it flows through the appliance.
Due to the absence of stand-by losses, the appliance offers greater
energy efficiency than storage type water heaters.

The input of heat into the water is electronically controlled. The
appliance will deliver any water temperature between 86 °F (30
°C) and 140 °F (60 °C). Please set the desired temperature using
the knob on the front cover. In case the “Power” light is flashing
while the appliance operates, the water flow rate exceeds the
heating capacity of the appliance. Reduce the hot water flow rate
in order to let the appliance achieve the set point temperature.
The maximum temperature is electronically limited to 140 °F (60
°C). In case you have questions regarding the way you plan to use
the appliance, please call our technical service line, see last side.

f
All plumbing work must comply with national and applicable
state and local plumbing codes.
f
A pressure reducing valve must be installed if the cold water
supply pressure exceeds 150 PSI (10 bar).
f
Make certain that the cold water supply line has been flushed
to remove any scale and dirt.
f
Install isolating valve in cold water line as shown in illustra-
tion “Mounting the appliance”. This allows the appliance to
be isolated for maintenance purposes.
f
Cold water connection (inlet) is on the right side of the ap-
pliance, hot water connection (outlet) is on the left side of
appliance.
f
Tankless water heaters such as the DHC-E are not required to
be equipped with a Pressure and Temperature Relief Valve
(P&T). If the local inspector will not pass the installation
without a P&T, it should be installed on the hot water outlet
side of appliance.
f
The appliance is designed for connection to copper tubing,
PEX tubing or a braided stainless steel hose with a ½“ NPT
female tapered thread. If soldering near the appliance is nec-
essary, please direct the flame away from the plastic housing
of the appliance in order to avoid damage.
f
When all plumbing work is completed, check for leaks and
take corrective action before proceeding.
6. Electrical
connection
DANGER Electrocution
Carry out all electrical connection and installation work
in accordance with relevant regulations.
Damage to the appliance and the environment
Observe the type plate. The specified voltage must match
the mains voltage.
DANGER Electrocution
Before beginning any work on the electric installation,
be sure that main breaker panel switch is „off“ to
avoid any danger of electric shock. All mounting and
plumbing must be completed before proceeding with
electrical hook-up. Where required by local, state or
national electrical codes the circuit should be equipped
with a „ground fault interrupter“.
DANGER Electrocution
As with any electric appliance. failure to electrically
ground appliance may result in serious injury or death.
f
The appliance should be connected to a properly grounded
dedicated branch circuit of proper voltage rating. In installa-
tions with several appliances, each appliance requires an
independent circuit. Please refer to the technical data table
for the correct wire and circuit breaker size.

The wire must be fed through the rubber seal located be-
tween the hot and cold water connections. Then feed wires
through strain relief clamp and tighten clamp down on wire.
The „live“ wires must be connected to the slots on the ter-
minal block marked L and L (L and N). The ground wire must
be connected to slot marked with the ground symbol. Strain
relief clamp with screws and rubber seal are provided.

7. Commissioning
DANGER Electrocution
Commissioning must only be carried out by an author-
ised contractor in accordance with safety regulations.
Damage to the appliance and the environment
Open hot water faucet for a few minutes until water flow
is continuous and all air is purged from water pipes. The
appliance’s plastic cover must be installed before the
circuit breaker is turned on.
f
Turn on circuit breaker to bring electrical power to the
appliance.
f
Turn the temperature selector clockwise and anti-clockwise,
to calibrate the temperatur selector.
f
Adjust the water temperature to the desired level using the
knob on the front cover of the appliance.
f
Turn on hot water and wait twenty seconds until temperature
has stabilized.
f
Check the water temperature with your hand and make sure
that it does not feel too hot. Reduce temperature if this is
necessary. A setting of 108 °F - 116 °F (42 - 47 °C) is recom-
mended for most applications.
f
Explain to the user how the appliance works and familiarise
him or her with its use.
f
Advise the user about possible hazards (hot water tempera-
ture up to 140 °F (60 °C). Hand over these instructions, to be
kept for future reference.
f
A setting of 108 °F - 116 °F (42 - 47 °C) is recommended for
most applications.
7.1 Appliance
handover
Explain the functions of the appliance to the user. Draw special
attention to the safety information. Hand the operating and instal-
lation instructions to the user.
