Please observe:
• e.g. VDE 0100

• The installation must comply with current IEC and national local regula-
tions or any particular regulations, specified by the local electricity supply
company
• The rating plate and technical specifications
• The appliance must be earthed!

Structural prerequisites

• The appliance must be installed via a permanent connection. Heater must
be earthed! Maximum cable cross section: 6 mm
• The electric wiring should not be injured. After mounting, the wiring must
not be direct accessible.
• An all-pole disconnecting device (e.g. via fuses) with a contact opening
width of at least 3 mm per pole should be provided at the installation end.
• To protect the appliance, a fuse element must be fitted with a tripping
current commensurate with the nominal current of the appliance.

Load shedding relay / box

If further three-phase appliances are connected, we recommend the use of
CLAGE's prepared load shedding box (art. no. 82260). Alternatively, a load
shedding relay (CLAGE art. no. 82250) can be connected to phase conduc-
tor L2. A special operating mode must be selec ted on the appli ance for this
purpose.
LCD Description
0 Operation without load shedding, manufacturer's setting
1 Operation with normal load shedding relay
2 Operation with sensitive load shedding relay
To change the operating mode, press the keys
taneously and wait until the desired mode (0, 1 or 2) is shown on the display,
then release the keys. Operating mode 1 must be selected first, thus to check
the correct operation of the load shedding relay at low appliance output (35
degree setpoint and low water flow rate). Mode 2 must be selected if the load
shedding relay flickers.
To change the operating mode of the CFX, see the instructions for the
enclosed remote control, chapter "Use", section "Settings".
Electrical connection

Electrical connection with pre-installed power cable

The appliance is to be connected with the pre-installed power cable to a ter-
minal box. If necessary, use one of the three predetermined breaking points
for the cable entry.
Alternative:

Electrical installation to a permanent connection

If, in case of particular local circumstances, connecting to a permanent con-
nection is the only possibility, continue as follows.
1. Disassemble the pre-installed power cable.
2. Dismantle off the power cable so that you can insert the cable with the
