The regulating valve in the pressure side must be adjusted to the correct water quantity. The water purging volume
should be roughly equivalent to the amount of water evaporated from the system. On request we will advise you
in choosing the suitable volume. Check the correct setting with a manometer. The volume of water for sediment
flushing should be set by adjusting the flushing bleed off valve. Check the correct installation of humidifier and
moisture separator modules. The arrow must show in the direction of the airflow (see Figure 20).
Check the tightness of the seals of the air washer and humidifier units, ie between the modules. If necessary apply
additional sealant.
Water Quality for humidifiers and air washers.
The information hereunder which refers to the water treatment is given for reference only. Water quality is of prime
concern to ensure proper operation of humidifier and air washer.
The water hardness of the fresh water has to be measured before considering any water treatement.
In accordance with the inherent degree of hardness in the water and the operational priority of the air conditioning
installation, appropriate water treatment can then be selected.
Figure 20
CAUTION! :
The use of improperly treated or untreated water in this equipment may result in scaling, erosion,
corrosion, algae or slime. The services of a qualified water treatment specialist should be engaged to determine what
treatment, if any, is required. The Trane warranty specifically excludes liability for corrosion or deterioration. Trane
assumes no responsibility for equipment damage or failure which results from the use of untreated or improperly
treated water or saline or brackish water.
Note: Honeycomb material made of cellulose may emit a certain smell during the first working hours. The is
absolutely normal and will disappear quickly.
To ensure a reasonable level of operational reliability, the quality of the supply water should be within the following
parameters (See tables 2 and 3).
