7 START-UP, CONTROL AND SHUT-DOWN
IMPORTANT WARNINGS:
1. Before starting check that the humidifier is in perfect condition, that there are no water leaks and that the elec-
trical parts are dry;
2. do not connect power if the appliance is damaged or even partially wet!
When installation is completed, flush the supply pipe for around 30 minutes by piping water directly into the drain, without
sending it into the humidifier; this will eliminate any scale or processing residues that may cause foam when boiling.
7.1 Preliminary checks
Before starting the humidifier, the following should be checked:
• the water, electrical and steam distribution connections have been made according to the instructions contained
herein;
• the water shut-off tap to the humidifier is open;
• the power fuses are installed and intact;
• the terminals 7I-8I or alternatively AB are jumpered or connected to the remote ON/OFF contact and the latter is
closed;
• the steam pipe is not choked;
• in case of humidification in ducts, the operation of the humidifier is slaved to the operation of the air fan (instead of or
in series with the remote ON/OFF contact);
• the condensate return pipe from the distributor is installed and free to drain;
• the drain pipe is correctly connected and free.
