Specifications are subject to alteration without notice
CONNECT ON TO WATER SYSTEM
The water supply is regulated by a built-in solenoid valve.
Connect the supply pipe to inlet branch. Fit a shut-off valve,
pos. 2, in the water supply pipe.
Table 1. Connection sizes
To avoid clogging, a water filter, pos. 3 (with a max mesh of
500 μm), should be fitted between the shut-off valve and
the humidifier.
Connect the drain pipe, pos. 5, to the humidifier’s drain connec-
tion. This must be fitted with a cleanable water trap, pos. 4, and
must run without any reduction in diameter to a floor gulley. In
the case of model 072-090 two water traps coupled in parallel
should be used.
The shut-off valve, water trap and water filter are not supplied.
CONNECT ON TO THE ELECTRICAL SYSTEM
(Must be carried out by an authorized electrician.)
When wiring is carried out on the installation site the supply
cable must be run via an external high voltage switch to the
control box through the cable gland fitted in the casing. The con-
troller has an internal 2 A fuse. The pump(s) supplied is/are
always wired for 3 x 400 V. The pump motors meet protection
class S 33 (IP44) and insulation class B.
