Water quality requirements
Requirements for water quality
The hot water tank in the Nilan units is made of steel, which has been given a double enamelling, to ensure an extra long service life. In
addition, the tank is equipped with a sacrificial anode as extra protection. It is important that the sacrificial anode is replaced regularly.
Most units are equipped with an electronic monitoring sacrificial anode, which gives an alarm on the user panel when it is time to
replace it.
In order for the sacrificial anode to function and protect the tank, it is required that the water quality complies with the following:
• Electrical conductivity (EC): Between 30 mS/m and 150 mS/m (millisiemens pr. m) @ 25 °C
• Chloride must be below 250 mg/L @ 65 °C
If the above criteria are not met, the sacrificial anode will not work as intended, after which the tank will be corroded., to

ATTENTION
The unit must be started up immediately after installation and connection to the duct system.
When the ventilation unit is not in operation, humidity from the rooms will enter the duct system and create condensate
water that can run out of the valves and cause damage to floors and furniture. Condensation may also form in the ven-
tilation unit, which can damage its electronics and fans.
