SAFETY NOTICE TO USERS
These instructions must be read thoroughly and understood before installation and operation of your Peak Gas Generator. Use of the Generator in a manner not specified by Peak Scientific Inst. MAY impair the SAFETY provided by the equipment. When handling, operating or carrying out any maintenance, personnel must employ safe engineering practices and observe all relevant local health and safety requirements and regulations. The attention of UK users is drawn to the Health and Safety at Work Act 1974, and the Institute of Electrical Engineers regulations.

Instructions for use Manual 1 Introduction
Zero Air Gas Generator 30th March 2005
The Peak Scientific Instruments range of Zero Air Gas Generators is designed to produce a constant flow of Zero Grade Air with a Hydrocarbon content (as Methane) of less than 0.1 ppm.

Unpacking and Installation
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.
ANY DAMAGE SHOULD BE REPORTED IMMEDIATELY TO THE CARRIER AND PEAK SCIENTIFIC OR THE DISTRIBUTOR FROM WHERE THE UNIT WAS PURCHASED.
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 sides of the unit nor, on the ZA180, the fan outlet on the top. The generator should be placed on a steady and level base. Alternatively, the unit may be wall mounted using the slots on the rear of the cabinet. These are on 100mm centres.

Electrical Connection
Important Electrical Notice
This unit is classified as SAFETY CLASS 1 equipment. 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): LIVE (L): Neutral (N): Fuse
Green & Yellow Brown Blue
or
Green Black White
The generator protection fuse in the pull out drawer of the mains inlet IEC euro connector located on the bottom right hand side of the cabinet adjacent to the off/on switch. The fuse is rated at 6.3 AMP. Connect the generator to a single-phase supply using the power cord provided.

Instructions for use Manual 4 Air Connection
Zero Air Gas Generator 30th March 2005
The inlet and outlet connections are 1/4" BSP female. The Inlet air should conform to the following specifications: Minimum Pressure Maximum Pressure Maximum Hydrocarbon Content 0.69 Barg / 10 psig 8.62 Barg / 125 psig 100 ppm
The inlet air should be oil free and pre-filtered to remove bulk moisture. Although not essential, an air drier up-stream of the generator will ensure a long and trouble free life.
Note:- The platinum catalyst within the Zero Air Catalytic Chamber will become poisoned if it comes into contact with any halogenated hydrocarbons, silicone sprays, silicone greases, phosphorous compounds, lead components, high sulphur vapours or other catalyst poisons.
The air supply should be connected to the generator inlet on the left side of the cabinet. The user's application should be connected to the outlet on the right side of the cabinet. To avoid leakage/impurity ingress, use PTFE tape on all fittings. Slowly, turn on the air supply until the required pressure is attained. There is no physical method of restricting the gas output from the generator. The user should therefore ensure that the application only receives a maximum flow not exceeding the rating for the generator. Demand in excess of the rated capacity of will result in higher levels of hydrocarbons in the delivered gas.

Principle of Operation
The Z015-108 Zero Air generator works on the fundamental principle of Catalytic Oxidation as illustrated in the following pneumatic diagram.

Cooling Coil
Outlet Cat Chamber
ZAxxx Pneumatic Diagram
Zero Air Generation
Inlet air is passed into the Generator via a coalescing filter, which removes bulk moisture and particles down to 0.1 micron. The air is then passed to the 'Zero Air' catalytic combustion chamber. This works on the principle of catalytic oxidation where hydrocarbons from the incoming compressed air supply are cracked to carbon dioxide and water. The hydrocarbon level in the form of methane is reduced to <0.1ppm, for this process to work the catalyst requires to be heated to approximately 400 degrees Celsius. The free Carbon and Hydrogen atoms then combine with Oxygen in the air to form Carbon Dioxide and Water. After the catalytic chamber the air passes through a simple cooling coil to reduce its temperature to a safe level. In the ZA180 this is assisted by a cooling fan.

Commissioning
This should be undertaken by a technically competent person.
With the generator installed as described earlier remove the front cover. Check that all the internal components are securely located and have not moved during transit. Open the air supply and turn the unit ON. Set the regulator on the Inlet Filter/Regulator to the desired pressure. Check that the cooling fan (ZA180) is operating and exhausting air out of the generator. Check that the red LED on the temperature control board is lit.
After a period of time (around 40 minutes) the Catalytic Chamber should have reached the required temperature. When this happens the relay on the Temperature Controller will “click” and the red LED will go out. The heater will then cycle on & off as required. Replace the front cover, the generator is now operational.
Do not touch any part of the Catalytic Chamber or Copper Lines as they will be VERY Hot.

Routine Maintenance
Due to the simplicity of design and the small number of parts the Peak Zero Air Generator will have a long and trouble free life. However as with all scientific and technical equipment it should be regularly inspected by a competent person and the following points noted. 1. Inlet Filter. Condensed moisture should be periodically drained from the filter. 2. Temperature Control. Check that the red LED cycles On & Off.
