4. 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 fl ows through the appliance.
Due to the absence of stand-by losses, the appliance offers greater
energy effi ciency than storage type water heaters.
26_02_02 _1086
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.
Note:
For reasons of appliance effi ciency and durability (scaling), the optimum temperature setting lies between 86°F
(30°C) and 120°F (50°C).
In case the “Power” light is fl ashing while the appliance operates,
the water fl ow rate exceeds the heating capacity of the appliance. Reduce the hot water fl ow 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.
5. Troubleshooting
Symptom Possible Cause Solution
No hot water not enough flow rate to
activate appliance
clean faucet aerator or shower
head
Water not hot enough water flow too high reduce water flow rate until
light on front cover stops
blinking
If you cannot remedy the fault, notify the contractor who installed
the appliance. To facilitate and speed up y our enquiry, please provide the serial number from the type plate (000000-0000-000000).

Damage to the appliance and the environment:
Excessive heat from soldering on copper pipes near the
DHC may cause damage.
All plumbing work must comply with national and applicable
state and local plumbing codes.
Notice for Australia / New Zealand:
The installation shall comply with AS/NZS 3500.4.
A pressure reducing valve must be installed if the cold water
supply pressure exceeds 150 PSI (10 bar).
Make certain that the cold water supply line has been fl ushed
to remove any scale and dirt.
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.
Cold water connection (inlet) is on the right side of the ap-
pliance, hot water connection (outlet) is on the left side of
appliance.
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.
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 necessary, please direct the fl ame away from the plastic housing

DHC-E 8/10 is a single unit that is switchable at installation via jumper for out put at 7.2 kW (Stage 1) or 9.6 kW (Stage 2).
1
This is our recommendation for overcurrent protection sized at 100% of load. Check local codes for compliance if necessary.
Tankless water heaters are considered a non-continuous load.
2
Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load.

4. Descripción del equipo
El calentador instantáneo DHC-E se distingue de los acumuladores
de agua convencionales en varios aspectos. No acumula agua caliente. En lugar de ello, el agua se calienta de inmediato mientras
fl uye a través del aparato. Debido a la ausencia de pérdidas de
calor en modo standby, el DHC-E ofrece un rendimiento energético
superior a un acumulador de agua caliente.
26_02_02 _1086
El calentamiento del agua se controla electrónicamente. El DHC-E
puede suministrar agua a una temperatura de 86 °F (30 °C) a 140 °F
(60 °C). La temperatura deseada puede ajustarse mediante el regulador de temperatura.
Indicación
Por razones de efi ciencia y vida útil (calcifi cación) del
aparato, el rango de ajuste óptimo de la temperatura
está entre 30°C (86°F) y 50°C (120°F).
Si durante el funcionamiento del aparato parpadea la luz “power”
(alimentación), el caudal del agua es superior a lo que puede
calentar la potencia calefactora del aparato. En ese caso, reduzca
el caudal para que el aparato pueda proporcionar la temperatura
ajustada. La temperatura máxima está limitada electrónicamente a 140 °F. Si tuviera cualquier pregunta adicional sobre el uso
previsto del DHC-E, diríjase al teléfono de nuestro servicio técnico
(véase última página).
5. Solución de problemas
Problema Causa Solución
No hay agua caliente El caudal de agua no es
suficiente para la activación del aparato
Limpiar el regulador de chorro
o el cabezal de la ducha
El agua no está suficientemente caliente
El caudal de agua es
demasiado alto
Reducir el caudal hasta que la
luz de la cubierta frontal deje
de parpadear
Si no puede solucionar la causa llame al instalador. Para poder
ayudarle mejor y con mayor agilidad, indique el número de la
placa de especifi caciones (000000-0000-000000).
