Precision is a modular system with differing flow rates that allows you to add
multiple generators as your gas and analysis demands change. The Precision
Series will keep your gas flowing with consummate accuracy and reliability,
whatever your needs, while fitting neatly into any lab space.
The Precision Zero Air Generator provides hydrocarbon free air, suitable as a
Flame Support Gas at Trace and Standard detection limits.
Features include:
• Suitable for Flame Support Gas at Trace and Standard detection limits
• Generates Zero Air on demand from Compressed Air
• Catalyst chamber to remove Hydrocarbons (as methane) to <0.05ppm
• Minimum maintenance with only a filter change per annum.

Although Peak Scientific take every precaution with safe transit and packaging,
it is advisable to fully inspect the unit for any sign of transit damage.
Check ‘SHOCKWATCH’ label for signs of rough handling prior to un-packing –
Any damage should be reported immediately to the carrier and Peak Scientific
or the Peak Partner from where the unit was purchased.
Follow the unpacking instructions posted on the side of the crate. It will require
one person to remove the unit from the shipping crate and lift the Generator
onto the bench.
Please save the product packaging for storage or future shipment of the
Generator.
After unpacking and a visual inspection, the unit should be
placed in a ventilated area away from direct sunlight. Care
should be taken not to obstruct the ventilation holes on the
side of the unit. The Generator should be placed on a steady
and level base.
Performance of the Generator (like all sophisticated
equipment) is affected by ambient temperatures. Prolonged
operation in temperatures exceeding 35°C will shorten the life
of the unit.

Each shipping box should contain the following: -
Zero Air Generator
¼” Teflon Tubing
¼”x¼” & ¼”x⅛” Compression Fittings
UK Mains Cable
EU Mains Cable
US Mains Cable
Installation Guide– Precision Zero Air
User Manual CD– Precision Zero Air
The Precision Zero Air generator weights approximately 16Kg, and as such
should only be lifted using safe lifting practice.
1. Remove the screws encircled in red around the bottom of the crate lid
and lift upwards.
2. Next, position your hands underneath the unit on either side, ready to
lift.
3. Ensuring your knees are bent and your back is straight, lift the unit to
the desired location.

Installation
Generator Environment
The Generator is designed for indoor use only. It should be
installed adjacent to the application(s) it is supplying. If this is
not convenient then the unit can be sited elsewhere, however,
consideration should be made of the lengths of pipe runs as
pressure drops can result from extended runs of pipe.
Performance of the Generator (like all sophisticated
equipment) is affected by ambient conditions. Note should
also be taken to the proximity of Air Conditioning outlets.
These can sometimes give rise to “pockets” of air with high
relative humidity. Operation of the unit within such a pocket
could adversely affect its performance. Consideration should
also be given to the air flow around the unit. It is
recommended that an air gap of 75mm (3”) should be
maintained down both sides and at the rear of the unit. Please
refer to the drawing below for the general dimensions of the
unit.
Maximum Ambient Conditions: 35°C (dry bulb) 70%RH (Max) Non-Condensing

Page 11 2013 © Peak Scientific - Rev. 0 - 09/01/13
The Precision Zero Air Generator should be connected to an air supply that, as
a minimum, meets ISO8753-1:2010 Class 1.4.1
In each cubic metre of compressed air, the particulate count should not exceed
20,000 particles in the 0.1 - 0.5 micron size range, 400 particles in the 0.5 - 1
micron range and 10 particles in the 1 - 5 micron size range.
A pressure dew point (PDP) of +3°C or better is required and no liquid water is
allowed.
In each cubic metre of compressed air, not more than 0.01mg of oil is allowed.
This is a total level for liquid oil, oil aerosol and oil vapour.

Page 12 2013 © Peak Scientific - Rev. 0 - 09/01/13
Supplied in the Fittings Kit are all the fittings required to connect the Precision
Zero Air Generator to the application. The contents of the Fittings Kit are as
follows:
1. ⅛” Compression Fitting × 1
2. ¼” Compression Fitting x 1
3. ¼” Teflon Tubing x 2m
4. C13 Mains Cable (UK) × 1
5. C13 Mains Cable (Euro) × 1
6. C13 Mains Cable (US) × 1
7. Installation Guide–Precision Zero Air × 1
8. User Manual CD– Precision Zero Air × 1
The Generator output port is located on the output panel at the rear of the
Generator.
It is recommended that PTFE tape is applied to the thread on the fittings to
ensure a leak-tight fit.
Any doubts as to the suitability of your compressed air supply should be
referred to Peak Scientific or any of their authorised partners.

Page 13 2013 © Peak Scientific - Rev. 0 - 09/01/13
Connect the Generator to an appropriate 110 or 230 volt single-phase supply,
refer to the generator serial plate for input specification and ensure your supply
matches the requirements.
If the appropriate power cord is not supplied; a new plug, rated to at least 10
amps, can be fitted by a qualified electrician.
This unit is classified as SAFETY CLASS 1. THIS UNIT MUST
BE EARTHED. Before connecting the unit to the mains supply,
please check the information on the serial plate. The mains
supply must be of the stated AC voltage and frequency.
EARTH/GROUND (E):- Green & Yellow or Green
LIVE (L)/PHASE (P):- Brown or Black
Neutral (N):- Blue or White
Electrical requirements are 110 or 230VAC nominal +/- 10% depending on
chosen model. However, running continuously at voltages outwith this is not
recommended. Extended periods at extremes can have a detrimental effect on
the operation and life of the Generator.

Page 14 2013 © Peak Scientific - Rev. 0 - 09/01/13
Switch the generator on using the power switch on the rear panel of the unit.
The LED’s on the front panel will illuminate YELLOW for the start-up period.
On completion of the start-up period, up to 60 minutes, the fascia will
illuminate GREEN. The Generator is now ready to be used.

Service Requirements
Servicing and/or repair of the Generator should only be
undertaken by a TECHNICALLY COMPETENT PERSON with
the Generator in a safely isolated condition.
Due to the simplicity of the design and the small number of moving parts, the
Precision Zero Air Generator will have a long and trouble free life. However as
with all scientific and technical equipment it should be regularly inspected and
serviced as below.
Peak Scientific offer two service plans. The Complete Service Plan, specifically
designed for Generators operated in critical environments, also includes full
breakdown cover, guaranteed response times and Generator upgrades if
available. Our Standard Service Plan, covering the basic needs of our
Generators, features special deals on spare parts and breakdowns.
If you want to know more about our Service Plan options and how we ensure
that your instrument can run with the maximum uptime and performance,
please contact us at maintenance@peakscientific.com
Clean the outside of the Generator only using warm soapy water and a clean
damp cloth. Ensure all excess fluid is thoroughly removed from the cloth prior
to use.
Cleaning should only be undertaken with the power switched
off and the power cord removed from the rear of the
Generator.
Under no circumstances should any solvents or abrasive
cleaning solutions be used as these can contain fumes that
could be harmful to the Generator.
