22 January 2019 Page 97 of 205
7.2 Minimum Distances
To operate and maintain the unit it must be installed with a mini-
mum spacing of 150 mm from walls, ceilings or other equipment.
7.3 Power Supply
The in-house electric power supply of the equipment must meet
the following conditions:

Single-phase, constant power supply

Type 230 V / 50/60 Hz

Type 115 V / 60 Hz
The power supply of the equipment must be made safe by the use
of an FI-switch (or RCD – Residual Current Device) of the kind
RCCB, Type B on the customer’s side.
7.4 Water Supply and Return
The in-house water supply to the equipment, as well as the drain-
age of the water, must meet the following requirements

“Very soft” or “soft” water quality (CaCO
3
concentration 0 mmol
L
-1
to 1.5 mmol L
-1
)
ATTENTION
Not observing the water quality requirements may lead to dam-
age or failure of the equipment.
The heating system has protection against dry running which is
based on measurement of conductivity. Therefore the heating
does not work or does not work properly when using demineral-
ised or distilled water as cooling liquid!

Constant water supply at a pressure of 2 ± 1 bar

Inlet temperature 10 °C up to 20 °C

Manometer to check the primary pressure available

The drain is heat-resistant and without back pressure
