ELECTRICAL INSTALLATION
The electrical installation and connection to the power supply must be done in compliance with the existing regulations and
standards for the building industry.
The fan's engine is equipped with an internal temperature limit fuse protecting the engine from overheating.
The unit set does not consist of: a feeding cable, or a master switch (see diagram)
The electrical installation must be done by an authorized person, acquainted with the Manual. The connection of the feeding
cable and master switch must be done in compliance with the electrical diagram (with or without the automatic control, de-
pending on the option chosen). Any damages incurred as a result of the aforementioned causes are not provided with the
Guarantee and the user will be charged with any costs of the device exchange. The connection of the automatic control should
be carried out following the electrical diagram.
In case of any doubts or problems, unplug the device and contact the device's installer or SONNIGER Authorized Service.
6.
WATER INSTALLATION
The installation of the unit should be done in a way enabling maintenance service; on both stub pipes, manual closing valves
should be installed to cut off the device. The feeding cables of the heater shall be connected following the symbols/marking on
the casing (inlet/outlet). In the case of an electromagnetic valve (with the option of the automatic control), it should be in-
stalled on the outlet as it may be damaged otherwise. When the pipework is being connected to the exchanger, secure the
connections of the heater from oscillating torque (see figure) that may cause leakage in the exchanger.
Heating medium
The connector pipes are at the back of the
device. When connecting the hydraulic
pipes/connections, make sure you secure
the connector pipes against rotational
torque. Notice that the connector pipes are
not strained by the pipes. The valve of the
heating medium is on the supply pipe and
the vent is on the return pipe.
Use flexible connections to allow the heater
to be turned to the sides. Depending on the
flexible connections, the maximum turn
is 70° - for HEATER CONDENS MAX,
78° - for HEATER CONDENS CR1, CR2,
CR3,
68° - for HEATER CONDENS ONE , to both
sides. The figure shows the maximum
angle to one side and 50° to the other with
minimal distance left for connections.
