If the system is equipped with a heater, make sure it is at least 20” (0.5 m) away from the
humidification unit.
If silencers are mounted in the air conditioning units make sure to locate the humidification
unit at a minimum distance of 10’ (3 m) before or after the silencers.
In order to avoid drops seeping over the humidification boxes, an even air flow over the full
cross section of the humidification unit must be guaranteed. If necessary, rectifiers or
perforated plates must be installed on the building side before the humidifier. If the air
velocity through the humidification boxes exceeds 750 fpm (3.8 m/s), mist eliminator must be
installed.
The effective height of the siphon in the drain line depends on the duct pressure. Correct
dimensioning of the siphon is the customer’s responsibility.
