PLUMBING
Personnel requisites: specialized plumber.
The machines equipped with a humidity control use a
system to introduce steam directly into the chamber.
In order to measure internal humidity, a psychometric
system (dry bulb - wet bulb) is used and the wet bulb is
humidified with demineralized water.
As this equipment has an incorporated demineralizer,
water can be taken for the above-mentioned uses in two
different ways:
A) directly from the mains supply.
• Prepare a mains water line which has the technical
characteristics given in the table below.
B) By pouring demineralized water into the special
container:
• No special preparation is necessary.

If the customer has a demineralized water line, he can
connect it to the machine instead of using the mains
supply.

• Connect the mains water supply to pipe union 10.
• For data concerning pressure, consumption and dimen-
sions, please refer to the table.

6.2
Connect pipe union 9 to the drain line (fig. 6.2);
diameter 3/4"G (models 250 - 340), 1"G (models
600-1200-1600).
The end can be connected to a preset drain or
else the water can be drained directly into a
collecting tray or container, without making any
drain-traps along the line.
CH0305-094
The drain is a free-fall drain and is not under pressure.
The machine is equipped with a system which enables
condensate water to be re-used (if it is clean), so that the
user can choose whether to programme condensate drain-
age to the outside or into the collecting container.
Use a pipe equal or larger in diameter to the machine pipe
union.
The connecting pipe will not only enable the condensate
water to flow out but it will also balance pressures inside the
test chamber in the case of unexpected temperature
variations, so no drain-trap should be prepared.
