A fresh mains cold water service should be used to supply the
unit. The water pressure should be between 1 & 6 bar & should
not exceed 40°C in temperature. In case the water pressure
exceeds 6 bar, a water regulator valve must be used.
The water supply connection is under the bottom of the unit. The
humidifier is delivered with a water inlet hose of 50 cm long with
a 3/4" female fitting to the cold water supply. A direct copper
connection is PROHIBITED.
A check valve should be located on the mains and cold wa-
ter service connection to the unit.
The inlet valve base has a basket filter (s.a. page 47).
The RTH humidifier uses water to produce steam so leaka-
ge may happen causing potential damage. If an installation
in false ceiling or abov e prime rooms (such as museum,
exhibition or laboratory rooms) is considered, ensure that
the floor below the humidifier is constructed from w ater-
proof materials (w ith draining facilities) to w ithstand any
water spilling during servicing or if a problem occurs.
Information about the w ater quality : chloride concentration :
< 75mg/l, phosphate concentration : < 5mg/l, chlorine consentra-
tion (3 to 6° dA) : < 100mg/l, poor concentration inCO2, organic
elements in poor concentration.
The RTH humidifier can run w ith the follow ing water
qualities :
•
Tap or raw water : water TH between 5° and 40° French
grade.
•
Demineralized water : 30µS/cm minimum (caution : the
demineralized water is corrosive; use appropriate piping
material : stainless steel, PVC)
•
Demineralized water of less than 30µS/cm : for ensuring a cor-
rect water lev el detection, a special floating water level detection
dev ice must come in replacement of the standard water level
system (s.a. attached picture). This replacement is f actory made
when this is specified on the purchase order or a replacement kit
is av ailable f or existing humidifiers (caution : the demineralized
water is corrosive; use appropriate piping material : stainless
steel, PVC). Please consult your local reseller.
