8.2 DHC-E 11 L
The DHC-E 11 L is only designed for a 208 V or 220 V connection.
Do not connect to a 120 V or a 230-240 V electrical service.
8.3 Temperature setting/anti-scalding protection

 Connect the lead of the electronic temperature control to po-
sition „A1“ in order to get the maximum outlet temperature
of 140°F (60°C).
The maximum temperature can be limited to 109°F (43°C):
 Connect the lead of the electronic temperature control to po-
sition „A2“.
 Reinstall the plastic cover.
8.4 Terminal block
We recommend using stranded wire to connect to the terminal
block. Crimp a ferrule over stranded bare wire to ensure a good
connection.
Consult the chart below for the recommended torque amounts on
the terminal block screws.
Screw Diameter (mm) Torque (N•cm) Torque (lbf•in)
2.8 30-40 2.65-3.54
2.8-3 35-50 3.09-4.42
3-3.2 50-60 4.42-5.31
3.2-3.6 60-80 5.31-7.08
3.6-4.1 90-120 7.96-10.62
4.1-4.7 120-180 10.62-15.93
4.7-5.3 150-200 13.27-17.7
Using the proper torque specifi cations to secure wire to the wiring
block helps to avoid personal loss or property damage.
See 12.4, “Data table”, pg. 11 for information on the proper
wire gauge size.

Damage to the appliance and the environment:
Open hot water faucet for a few minutes until water fl ow
is continuous and all air is purged from water pipes. The
appliance’s plastic cover must be installed before the cir-
cuit breaker is turned on.
 Turn on circuit breaker to bring electrical power to the
appliance.
 Turn the temperature selector clockwise and anti-clockwise,
to calibrate the temperatur selector.
 Adjust the water temperature to the desired level using the
knob on the front cover of the appliance.
 Turn on hot water and wait twenty seconds until temperature
has stabilized.
 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.
 Explain to the user how the appliance works and familiarise
him or her with its use.
 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.
 A setting of 108°F - 116°F (42 - 47 °C) is recommended for
most applications.
9.1 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.
