Water drain

The drain is a plastic hose and is routed out of the unit by means through the openings in the unit provided

for this purpose (see graphic below).

When creating the drain, attention is to be paid to provision for cleaning. As the water drain is depressuri-

zed, route the drain hose directly into an open collector funnel to ensure free discharge. The drainage pipe

should be routed to the drain with sufﬁ cient gradient (1/4 inch of a drop every 10 feet) and should be located

approximately 30 cm (11.81 inch) below the humidiﬁ er. Attention is to be paid to temperature resistance

when plastic pipes are used. If copper pipe is used, it must be earthed. For the drainage pipe an inside

diameter of 32 mm (1 1/4 inch) is recommended. However, the minimum inside diameter should not be less

than 25 mm (1 inch).

9.1.4 Commissioning

Completely open the shutoff valve in the water supply line. As soon as the controller requires the humidiﬁ er

function, the heating current is switched on; after approximately 30 seconds water is fed into the steam

cylinder through the inlet valve which opens, and fully automatic operation begins.

IMPORTANT NOTICE:

After the water pipes have been connected, the supply piping must be ﬂ ushed for approx. 30 minutes,

where the water is directly conducted into the drain, without letting it ﬂ ow into the steam humidiﬁ er.

This removes residues or substances of the installation process, which otherwise could block the

ﬁ l l valve and cause foam during the boiling process.

Decommissioning the humidiﬁ er

The steam cylinder is to be emptied if the humidiﬁ er has been out of operation for a long period (e.g. in

summer, decommissioning the air conditioning system etc.) (see 9.1.6 Maintenance - Drainage).
