5.5.2 Notes on water installation
Water supply
The water supply is to be carried out according to the gure found in chapter 5.5.1 and the applicable
local regulations for water installations. The indicated connection specications must be observed.
– The installation of the lter valve (accessory "Z261", alternatively a shut-off valve and a 5 µm water
lter can be used) should be made as close as possible to the steam humidier.
Note: on large units with two steam cylinders, on double units and on Linkup systems each unit
must be connected separately via a lter valve (or shut-off valve and water lter) to the water supply.
– Admissible water supply pressure:
– 1.0…10.0 bar (units without drain water cooling)
– 2.0…10.0 bar (units with drain water cooling)
Note: the supply water system must be hammer-free. For mains pressures >10 bar, the connection
must be made via a pressure reducing valve (adjusted to 2.0 bar). For mains pressures <1.0 bar
(units without drain water cooling) <2.0 bar (units with drain water cooling) please contact your
Condair supplier.
– Notes on water quality:
– For the water supply of the Condair RS, use exclusively untreated drinking water, water from
RO system or de-ionized water.
– The use of additives such as corrosion inhibitors, disinfectants, etc. is not allowed, since these
additives may endanger health and affect proper operation.
– The connection material must be pressure-proof and certied for use in drinking water systems.
– Important! Before connecting the water line, the line must be well ushed out.
CAUTION!
The thread at the humidier connection is made of plastic. To avoid overtightening, the union nut
of the water pipe must be tightened by hand only.
Water drain
The water drain is to be carried out according to the gures found in chapter 5.5.1 and the applicable
local regulations for water installations. The indicated connection specications must be observed.
– Make sure that the drain pipes, the funnel(s) and the siphon(s) are correctly xed and easily acces-
sible for inspections and cleaning purposes.
– The draining temperature is: 80…90 °C (with optional drain water cooling <60°C). Use temperature-
resistant installation materials only!
– Always lead the supplied drain hose from the connector to the left down to the funnel (see Fig. 21).
On large units with two steam cylinders each drain line must be led into a separate funnel with trap
(see Fig. 22).
On double unit the drain hoses must be connected with hose clamps to a collector with constant
downslope (min. 15 %/8.5°). The drain of the collector must be led with constant downslope (min.
15 %/8.5°) into a funnel with trap (see Fig. 23). The funnel must be positioned with a lateral off-set
to the left side of the unit, to prevent damage to humidier due to rising steam.
– Attach drain line(s) in such a way, that it/they cannot slip out of the funnel(s) and that it/they cannot
bottom out in the funnel(s).
– The open end of the drain line(s) must not touch the funnel(s) (min. air gap 2 cm).
