1.1 Symbols and terminology
In the unit and in this manual are used some symbols to signal to the user one or more information.
Consult the user manual in all cases where this symbol is marked on the equipment in order to find out the
nature of the potential hazard and any actions which have to be taken to avoid them.
Warning/caution.
Used in this manual to signal to pay particular attention to the operation in progress.
Failure to heed the warnings/cautions given may cause severe personal injuries and
material damage.
In this manual with this symbol there is a message showing the relative type of warning.
!
Warning/caution – unit labels.
When present in the generator in a certain place, it signals a specific warning:
•data plate – to avoid electrical problems and for correct power supply of the unit,
the general line must be sized in accordance with the data indicated (power
supply, frequency and power).
•label with fuses rating – when replacing one or more fuses, use only fuse/s that
comply with the specifications indicated.
Warning – Mechanical moving parts.
Indicated in the unit (on the compressor protective panel) to signal to pay particular
attention to the mechanical moving parts contained in the unit.
To avoid any possible personal damage/injuring, be sure the unit is completely stopped

4 Available accessories (not ncluded, to be requested separately)
In this section will be described some accessories useful for a safety and convenient utilisation of NG-
CASTORE-XS-iQ.
All these parts are not ncluded by default
They can be order and nstalled later by the operator when the r funct on s cons dered more su table and
conven ent.
They have been des gned for an easy and qu ck nstallat on and operat on.
4.1 Purge tank
For NG-CASTORE-XS-iQ series is available a special tank kit useful to contain the waste water due from the
water condensing inside the generator during operation.
This kit is composed by:
•1 x tank litres with a 90° Quick fitting for tube 6mm installed
• meters of tube Diameter 6mm
•1 x fitting (1 x 1/4” BSPP male threaded) to connect the tube Diameter 6mm from generator to purge
tank
4.2 Pressure regulators box
For NG-CASTORE-XS-iQ series have been developed two regulators boxes:
•6920.71.30 → Box with two pressure regulators (N2 outlet and Dry-A r outlet)
•6920.71.40 → Box with three pressure regulators (N2 outlet, Dry-A r outlet 1 and Dry-A r outlet 2)
These accessories are useful when the application is more than meters farther from the gas source (NG-
CASTORE-XS-iQ).
Using them, with a suitable installation, the operator reduces the pressure loss due to the tubes length and
has the advantages of a convenient access to pressure control.
6920.71.30 6920.71.40
These accessories allow the control of the outlet pressures (N2 and Dry-Air) in a place with convenient
access.
6920.71.30 is a useful tool to put control of outlet pressures in a comfortable position
6920.71.40 has the same characteristics of 6920.71.30 with, in addition, the capacity to divide the single
Dry-Air outlet into two pressure regulated Dry-Air outlets.
Box regulators are provided with the following material:
For 6920.71.30:
•1 x fitting for tube Diameter 1/4” (1/8” BSPP male threaded)
For 6920.71.40:
•2 x fittings for tube Diameter 1/4” (1/8” BSPP male threaded)

5.2 Positioning
Nitrogen build-up may lead to a lack o oxygen and there ore create the risk o asphyxia.
Always make sure all o the openings o the unit are kept clean and ree o obstructions. Keep the
generator away rom heat and lames.
The generator must be stored, installed and used only indoor
The generator should be positioned on a flat surface able to withstand a weight greater than 200 kg and
not exposed to vibrations.
Once positioned, lock the wheels using their locking systems to secure the unit in its position and
prevent possible movement
Do not position the generator near naked flames or other sources of heat
Always leave sufficient clearance for the circulation of air around the appliance, as shown below:
A >= 10 cm
If the unit is positioned under a laboratory desk leave sufficient clearance al the sides and leave
clearance at the rear to permit a good air circulation
Place the unit in a position that allows a comfortable access to the mains plug or the mains connector
placed at the back side of the unit in order to easily disconnect the unit from the supply mains
Do not use the generator in a sealed environment or without suitable ventilation
Do not use the appliance in temperature and humidity conditions outside of the limits specified for
operation (see 2.3)
These generators must be installed in an environment capable of disposing of the heat produced (see
heat value 2.3)
To perform ma ntenance operat ons nvolv ng parts ns de the generator, the operator needs to access to the
removable s de panels and/or the top panel. Place the generator n a space that allows a comfortable access
for ma ntenance operat ons.
