3.1 Safety instructions
In any case, the water feed pipes that you have laid
must be flushed thoroughly before connecting them
to the humidifier. You should use copper piping only.
Note that the drainage facility should provide the
possibility of performing cleaning and maintenance.
The drainage pipe should have a decline to the
drainage system of at least 5%.
A fine filter should be fitted at the water intake
to the humidifier; this prevents the rapid build-up of
impediments in the inlet filter of the inlet valve.
All work pertaining to the electrical installation must be carried out
by qualified personnel only. The customer is responsible for verifying
the qualifications of the technicians concerned.
Before performing any electrical work, all power to the humidifier must be
disconnected.
Please observe local regulations concerning electrical installations.
The installation must be fitted with a device which disconnects the unit
(with a contact opening of at least 3 mm) on all phases from the mains
power supply.
NORDMANN humidifiers are designed to be connected to the earth
lead and are categorised as belonging to Protection class 1 for electrical
equipment.
The connection details are provided in the wiring diagrams for each type
of unit. Each unit is supplied with the appropriate wiring diagram.
