Has filter valve (accessory "Z261") or shut-off valve and 125 µm water filter respectively been
installed in supply line to each unit module?
Has acceptable water pressure (without drain water cooling: 1 – 10 bar, with drain water cooling:
2 – 10 bar) and acceptable water temperature (without drain water cooling: 1 – 40 °C, with drain
water cooling: 1 – 25 °C) been connected?
Does the water supply capacity match the humidifier and is the minimum inside diameter of 8 mm
of the supply pipe maintained throughout the entire length (min. internal diameter of 12 mm for
systems with optional drain water cooling recomended)?
Are all components and pipes properly secured and are all threaded connections securely tight-
ened?
Is the water system properly sealed?
Does the water supply installation meet the requirements of the local regulations for water instal-
lations?
– Water drain
Is the minimum inside diameter of the drain pipe(s) of 30 mm maintained throughout the entire
length?
Has/have drain pipe(s) been installed with a downslope of at least 15 %/8.5°?
Has the heat resistance of the material used been verified to be at least 100 °C (60 °C for sys-
tems with optional drain water cooling)?
Is/are the drain hose(s) properly secured (hose clamps at unit connection tightened)?
Is there an air gap (min 2 cm) between the open end of the drain line and the funnel?
