HighPressure Humidifier - Constant Pressure
7 Installation
7.1 Main unit
The cabinet of the humidification system must be installed in a ventilated and protected place. It must be
placed on a flat and stable surface. For a correct use and operation, as well as for an easy maintenance,
leave enough free space around the machine. To enable the correct ventilation of the unit is necessary to
ensure a free space of at least 20 cm close to the perforated panel for ventilation, which is located on the
right wall of the machine.
Do not place the machine in dangerous and/or explosive/inflammable places.
After installation the red cap of the oil tank, used for the transport, must be replaced by the yellow one,
used for normal working operation, provided with the system.
The access internal parts of the cabinet remove screws that secure the top and side panels.
During the first installation and all the operations of maintenance please take care
of the temperature sensor installed at the exit of high pressure pump.
Its damage may cause the breakage of the high pressure system.
Before first switch-On replace the RED transport cap with the YELLOW cap having a
built-in dipstick provided.
7.2 HPNCTRL
The HPNCTRL card must be installed close to the distribution rack.
Electrical connections scheme is reported at the end of the document. Electrical connections to the high-
pressure solenoids (section, feed and drain) and main unit must be realised respecting local regulation.
The HPNCRTL card receives the regulation signal (ON/OFF or Proportional).
The HPNCRTL unit opens the drain solenoid to empty the solenoids lines when the control signal is 0.
The control signal must be 0 in case of ventilation system failure or system shut off
7.3 Distribution rack
The case of the rack must be installed external to the AHU and fixed using dedicates holes. Hydraulic
connections to the rack (high pressure water input and drain) are respectively on the top and bottom of
the case. Three holes must be realised into the sandwich panel to let nozzles lines enter the AHU. When
mounting the nozzle lines a slope towards the case must be realised. This slope allows the lines to empty
totally when the system is off.
The rack must be installed in direct contact (thermally connected) to the HEATING COIL, to let the rack dry
when it is not used.
When shutting down the system for long periods, the humidifier must be switched-off before the
ventilation system, so to assure that the humidifier chamber is dry before complete shutdown.
