Unpacking
Although Peak Scientific takes every precaution with safe transit and packaging, it is
advisable to fully inspect the unit for any sign of transit damage.
Check ‘SHOCKWATCH’ and ‘TIP-N-TELL’ labels for signs of rough handling prior to
unpacking.
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 two
people to remove the unit from the shipping crate and to manoeuvre the air compressor
onto the bench.
Please save the product packaging for storage or future shipment of the generator.
Note: Included with the generator is a “Fittings Kit” containing mains power leads for
UK, EU & US and also all the required fittings and warranty registration card. Be careful
not to discard these with the packaging.
Page 17
Fittings Kit Contents
Supplied in the Fittings Kit are all the fittings required to connect the generator to the
application. The contents of the Fittings Kit are as follows:
1. PTFE Tubing x 3m
2. ¼” Compression Fitting x 1
3.
⁄8” Compression Fitting

x 1
4. UK Mains Power Cable x 1
5. EU Mains Power Cable x 1
6. US Mains Power Cable 110v
x1
7. US Mains Power Cable 230v
x1
All of the generators output ports are located on the output panel at the rear of the unit.
Unpacking Instructions
The unit weight constitutes a two person lift and as such, safe lifting practices should
be employed; do not attempt to lift on your own, as you will significantly increase the
chance of injury & damage to yourself and others around you.
1. Remove the screws encircled in red around the bottom of the crate lid and lift
upwards.
2. Next, with someone on either side of the unit, position your hands underneath the
unit ready to lift.
3. Ensuring your knees are bent and your back is straight, lift the unit to the desired
location.
Page 18
Installation
Generator Environment
The generator is designed for indoor use only. Storing of corrosive substances near the
generator or its compressed air supply is not recommended. Saline salt solution spillages
around the generator or its compressed air supply should be cleaned up immediately. 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.
Please ensure generator is operated in a well ventilated environment and is positioned
so as to permit easy electrical disconnection if required.

Air Purity
The Precision Zero Air Series generator should be connected to an air supply that, as a
minimum, meets ISO8753-1:2010 Class 1.4.1
Class 1 Particulate
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.
Class 4 Water
A pressure dew point (PDP) of +3°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. This is a
total level for liquid oil, oil aerosol and oil vapour.

Start-Up Sequence
Switch the generator on using the power switch on the rear panel of the unit. Please
note: On 30L generators, air will only flow through the generator when the power is
switched on. The LED’s on the front panel will illuminate YELLOW for the start-up
period.
YELLOW for 60 Minutes
On completion of the start-up period, up to 60 minutes, the fascia will illuminate GREEN
or BLUE (70-**** Part Numbers Only). The generator is now ready to be used.
GREEN / BLUE
On Demand Gas
The generator system will produce zero air on demand. If the application is operating
and requires a gas flow, the generator it is connected to will supply this to suit the
requirements of the application. If the application requirement for gas stops, the
system will also stop. If the demand from the application starts again, the system will
automatically start again to suit the demand.
Unusual Operation
If at any time the generator begins to emit excessive noise or vibration, then it should be
switched off and you should contact Peak Scientific or the Peak Partner from which the
generator has been purchased.
Page 28
Connecting to the application
Once the initial purge run of 60 minutes has completed the generator is now ready to be
connected to the application(s).
The pressure must be allowed to dissipate before connecting the
generator to the application(s)
CAUTION
Attach the 1/8” compression fitting to the outlet of the generator. Using either 1/8”
copper or stainless steel tubing, connect the outlet of the generator to the inlet of the
application.
If you require more tubing than is supplied please refer to the Tubing Lengths section.
CAUTION
Once the tubing is connected to the application, please ensure that it is
thoroughly checked for being leak-tight. Even the slightest leak in the
gas supply between the generator and the application can lead to a
reduction in efficiency.
Tubing Lengths
CAUTION
The diameter of the tubing which will be connected to the gas outlet is
important and is determined by the length of tubing required. Failure to
follow these recommendations could lead to an excessive pressure drop
between the generator and its application.
< 10 meters:
Use ¼”/3⁄16” (¼” O/D, 3⁄16” I/D) P.T.F.E. tubing.
> 10 - 40 meters: Use 3⁄8”/ 5⁄16” (3⁄8” O/D, 5⁄16” I/D). Tubing and fittings not supplied
in the fittings kit.
> 40 metres:
Please contact Peak Scientific with the relevant distance and
we will calculate the flow resistance and the tubing size required.
A combination of ¼”/3⁄16” and 3⁄8”/5⁄16” tubing may be used to ensure that there is no large
diameter tubing within the lab (i.e. for the first 20 meters from the generator use 3⁄8”/5⁄16”
and the final 10 meters to the application use ¼”/3⁄16” tubing). Keep the connections and
bends to a minimum.

Chlorinated hydrocarbons
Chlorinated hydrocarbon compounds and chlorofluorocarbons (or freons) will severely
damage the hydrocarbon catalyst used in this gas generator, resulting in generator
failure.
The generator can also be contaminated by high concentrations of lead, sulfur or
phosphorous compounds, heavy metals and long chain polymers. Care should be taken
to avoid introducing these compounds into this gas generator. Please ensure that none
of these compounds are stored near the intake of the compressed air supply supporting
the gas generator.
Chlorinated Solvents
Under no circumstances should any Chlorinated solvents be stored in the immediate
vicinity of the gas generator or the compressed air source. Failure to adhere to this
could result in severe contamination of the generator or failure.
Cleaning
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.
CAUTION
Under no circumstances should any chlorine-based bleach, solvents or
abrasive cleaning solutions be used in the same room as the generator,
including on the generator itself, as these can contain fumes that could
be harmful to the generator.
Care should be taken with Leak Detections Liquids.
CAUTION
