General safety instructions

We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the water heater
are used.
Material losses
!
Observe the maximum inlet temperature. Higher tempera-
tures may damage the water heater. You can limit the max-
imum inlet temperature by installing a central thermostatic
valve.
WARNING Electrocution
This water heater contains capacitors which are discharged
when disconnected from the power supply. The capacitor
discharge voltage may briefly exceed 60 V DC.

Instructions, standards and regulations

Note
Observe all applicable national and regional regulations
and instructions.
- The electrical resistivity of the water must not fall below that
stated on the type plate. In a linked water network, factor in
the lowest electrical resistivity of the water. Your water supply
utility will advise you of the electrical resistivity or conductivity
of the water in your area.

Install the water heater in a room that is free from the risk
of frost.
Install DHC Trend in a frost free area. If frost may occur, remove
the unit before freezing temperatures set in.
Always install the water heater vertically with plumbing fittings
pointing downward. Install the water heater near the draw-off
point to minimize pipe runs and thermal losses.
Taps: Do not use open vented or non-pressurized taps.
The water heater is suitable for under-sink and over-sink installa-
tion.
