Installation	is

Air humidity and ambient temperature

The boiler room must be frost-free, or be protected against frost. The table shows the environmental conditions that must be adhered to for correct functioning of the electronics present in the appliance to be guaranteed.

Air humidity and ambient temperature specifications

Air humidity and ambient temperature

Air humidity	max. 93% RV at +25°C

Ambient temperature	Functional: 0 < T < 60°C

3.3.2Appliance maximum floor load

In connection with the appliance's weight, take account of the maximum floor loading, refer to the table.

3.3.3Water composition

The appliance is intended for heating drinking water. The drinking water must comply with the regulations governing drinking water for human consumption. The table gives an overview of the specifications.

Water specifications

Water composition

Hardness	> 1.00 mmol/l:
(alkaline earth ions)	• German hardness> 5.6° dH
	• French hardness > 10.0° fH
	• English hardness > 7.0° eH

Conductivity	> 125 µS/cm

Acidity (pH value)	7.0 < pH value < 9.5

Note

If the water specifications deviate from those stated in the table, then the tank protection cannot be guaranteed (16 "Warranty (certificate)").
