2 - INSTALLATION
2.1 Before installing
In order to start the UCP humidifier, it is necessary to comply with the following requirements:
Connection to the electric power supply with voltage and frequency suitable for the machine,
with grounding and safety devices;
Connection to water supply (pressure required: between 2 and 4 atm);
The operating temperature must be between 1°C and 40°C.
The unit must be supplied with drinking water, or water having a low fixed residue, or treated
water. The water quality affects the unit maintenance, the frequency of the maintenance
operations and the correct functioning of the humidifier.
Dynamic ventilation system (air speed >3m/s)
We suggest to provide the unit with temporized discharging system to drain the water tank, as a
bleed-off valve, in order to keep the unit in good working conditions.
The installation must meet the safety requirements provided by local regulation in force.
Follow the regulations of the UNI 8884 standard “Requirements and treatment of water cooling
and humidification system.” conductivity <100 μS/cm and total hardness <5° fH (50 ppm CaCO3).
Make sure that all the connections necessary to operate the equipment have been properly prepared.
2.2 Positioning
The UCP humidifier must be installed either in front of a stirring air fan or as a part of a dynamic
ventilation system.
The UCP humidifier / cooler must be installed horizontally, hanging off the ground, with the non-
atomized water tank facing down.
Use the suitable holes at the base of the motor to hang the machine and to hold it in the correct
operating position with an appropriate fixing system to avoid vibration (the distance between
holes is shown in Figure 2.1; use vibrations reducer devices);
Fig. 2.1 Fixing holes position
The positioning of the UCP must be done by maintaining the minimum recommended distance that allows the
correct operation of the machine and to perform maintenance when needed.
Choose the most suitable position for the humidification and the cooling of the environment according to the
type on installation adopted
These humidifiers could be installed in air treatment units or inside canalizations for air distribution.
Is necessary to predispose a drain system for non-atomized water.
It’s almost necessary, in order to maximize the fog quality, to adopt a drop separator (see fig. 2.2).
When the humidifier is used in combination with a fan it is necessary to maintain a minimum distance of 1m
from the ceiling and the walls in order to prevent fog condensation on walls. As for the front wall, the distance
has to be calculated based on the fan model chosen and the amount of water atomized.
