ENVIRONMENT
Th e equipment should be located indoors in an environment that protects it from direct sunlight, moisture, and dust. Changes in
temperature, humidity, and airborne pollution will aff ect the environment in which the equipment is operating and may impair the safety
and operation. It is the customers’ responsibility to ensure that the environmental conditions specifi ed for the equipment are maintained.
SPACE REQUIREMENTS
Th e equipment should be mounted on a fl at surface capable of supporting its own weight plus the weight of all ancillary parts. Th ere must be
adequate space around the equipment to allow airfl ow and access for maintenance purposes and lifting equipment. A minimum spacing of
approximately 500mm (20”) is recommended around all sides.
Do Not position the equipment so that it is diffi cult to operate or disconnect from the electrical supply.
Once positioned the equipment should be secured to the fl oor using M20 bolts.
VENTILATION REQUIREMENTS
AIR INLET QUALITY
Th is generator is designed for use with clean dry compressed air in accordance with ISO 8573-1:2010 class 2.2.1.
ISO8573-1:2010 is an international standard that specifi es the purity classes of compressed air with respect to solid particulates, water and oil.
Understanding the requirements of the standard falls outside of the scope of this manual, however the following table summarises the
classifi cation for each contaminant. Further information on ISO 8573-1 can be found in the domnick hunter publication “A GUIDE TO THE
ISO8573 SERIES COMPRESSED AIR QUALITY STANDARD” (Stock Number: 17 400 4765).
ISO 8573-1:2010 class 2.2.1 equates to the following:
Class 2 (Solid Particulate)
In each cubic metre of compressed air, the particulate count should not exceed 400,000 particles in the 0.1 - 0.5 micron size range,
6,000 particles in the 0.5 - 1 micron size range and 100 particles in the 1 - 5 micron size range.
Class 2 (Water)
A pressure dewpoint (PDP) of -40 o C or better is required and no liquid water is allowed.
Class 1 (Oil)
In each cubic metre of compressed air, not more than 0.01mg of oil is allowed. Th is is a total level for liquid oil, oil aerosol and oil
vapour.
ELECTRICAL REQUIREMENTS
Connection to the electrical supply should be made through a switch or circuit breaker rated at 250VAC, 15A with a minimum short
circuit rating of 10KA. Th
is device should have a disconnection time not exceeding 40mS and all current carrying conductors should be
disconnected.
Th
e device chosen should be clearly and indelibly marked as the disconnecting device for the equipment and be located in close proximity to
the equipment and within easy reach for the operator.
Over current protection must be fi tted as part of the building installation. Th
is protection should be selected in accordance with local and
national code regulations with a minimum short circuit rating of 10KA.

Warning
Due to the nature of operation there is a possibility of oxygen enrichment surrounding the generator. Ensure that the area is
adequately ventilated. Where the risk of oxygen enrichment is high, such as a confi ned space or poorly ventilated room, the
use of oxygen monitoring equipment is advisable.
Nitrogen is not a poisonous gas but, in a concentrated form, there is a risk of asphyxiation. Depending upon the model and
operating pressure, the generator is capable of delivering nitrogen at a fl ow rate of 47.64 m
3
/hr. If the generator is operated
within a confi ned space ensure that adequate ventilation and oxygen monitoring equipment is fi tted.
