9.1.3 Supply connections

The steam humidiﬁ er is installed and electrically connected in the InRoom CRAC at the factory. Follow local,

state and national codes when attaching water lines.

Water supply

The water connection is made from the cold water supply and is to be equipped with a shut-off valve. Install a

ﬁ l ter to retain solid particles. The humidiﬁ er can be connected directly to the supply by a threaded tenon of 3/4

inch when the water pressure is between 1 and 8 bar (14.5 and 116 psi). The pipe should have a diameter of

at least 1/4 inch (6 mm). If the line pressure is more than 8 bar (116 psi), the connection must be made with

a pressure reducing valve (set to 4-6 bar [60-85 psi]). In each case ensure that the manufactured water pipe

upstream of the connection to the humidiﬁ er is ﬂ ushed properly. We recommend only using copper pipes.

The water supply temperature must not exceed 40

°C (104 °F).

Caution:

Do not treat the water with softeners.

This could result in corrosion of the electrodes and in the formation of foam with conside-

rable operational interruptions.

Prevent:

1. The use of well water, process water or water of cooling circuits and generally chemically

or bacteriologically polluted water.

2. The addition of disinfectants or anti-corrosion liquids, as these are very irritating for the

respiratory ducts.
