space.
Other features include:•

Suitable to supply compressed air for Precision Nitrogen, Nitrogen Trace and Zero Air
systems as well as Peak Scientific TOC models.

•

Generates compressed air on demand.

•

Minimum maintenance with only a compressor service and filter change per annum.

•

Small and Stackable.

With the Precision Air Compressor based on proven technology, it provides a source ofdry, clean and oil-free compressed air.
To ensure this air compressor model meets our high expectations with regards
to reliability and performance, we have tested this new model extensively at our
manufacturing plant and with end users around the world to ensure reliability andlongevity of the system.

Unpacking
Although Peak Scientific takes every precaution with safe transit and packaging, it isadvisable 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 thePeak 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 air compressor.
Note: Included with the air compressor 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 12Fittings Kit Contents
Supplied in the Fittings Kit are all the fittings required to connect the air compressor to
the application. The contents of the Fittings Kit are as follows:
1. Teflon Tubing								x 3m
2. ¼” Compression Fitting						x 23. ¼” Tee Compression Fitting						x 14. 2.5mm Hex Key							x 15. UK Mains Power Cable						x 16. EU Mains Power Cable						x 17. US Mains Power Cable 110v						

x18. US Mains Power Cable 230v					

x1All of the air compressor output ports are located on the output panel at the rear of theunit.

Unpacking Instructions
The unit weight constitutes a two person lift and as such, safe lifting practices shouldbe employed; do not attempt to lift on your own, as you will significantly increase thechance 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 theunit ready to lift.
3. Ensuring your knees are bent and your back is straight, lift the unit to the desired
location.

Page 13

Installation
Compressor Environment
The air compressor is designed for indoor use only. Storing of corrosive substances near
the air compressor is not recommended. Saline salt spillages around the air compressor
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 air compressor (like all sophisticated equipment) is affected byambient 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 situated in a well-ventilated environment and is positioned toallow easy disconnection from the mains supply if required.
Minimum Operating Ambient Temperature:

5 °C (41 °F)

Maximum Operating Ambient Temperature:

35 °C (95 °F)

Electrical Connection
Connect the air compressor into an appropriate electricity supply, between 100-230VAC.
Refer to the air compressor serial plate for input specification and ensure your supply
matches the requirements.
If an appropriate mains power cords is not supplied or a substitute one is used thenensure that all components of it the plug, cord and connector have adequate ratings
for the generator and appropriate approvals for the country of use. Failure to do so
could cause damage to the generator or risk overloading of the power cord

WARNING

This unit is classified as SAFETY CLASS 1. THIS UNIT MUST BE
EARTHED. Before connecting the unit to the mains supply, pleasecheck the information on the serial plate. The mains supply must be of
the stated AC voltage and frequency.

Electrical requirements are nominal +/- 10% depending on chosen model. Extended
periods at extremes can have a detrimental effect on the operation and life of the Air
Compressor.
If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment maybe impaired.
WARNING

Page 17

Connecting to the application
Once the initial purge run of 30 minutes has completed the compressor is now ready to
be connected to the application(s).
The pressure in the internal storage tanks must be allowed to dissipate
before connecting the compressor to the application(s)CAUTION

Attach the ¼” compression fitting to the outlet of the air compressor. Using the ¼” tubing
supplied, connect the outlet of the air compressor to the inlet on 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 isthoroughly checked for being leak-tight. Even the slightest leak in thegas supply between the air compressor and the application can lead toa reduction in efficiency.

Tubing Lengths

CAUTION

The diameter of the tubing which will be connected to the gas outlet isimportant and is determined by the length of tubing required. Failure
to follow these recommendations could lead to excessive pressure drop
between the air compressor 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 andwe 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 nolarge diameter tubing within the lab (i.e. for the first 20 meters from the air compressor
use 3⁄8”/5⁄16” and the final 10 meters to the application use ¼”/3⁄16” tubing). Keep theconnections and bends to a minimum.

Page 18

Normal Operation
The Precision Air Compressor is designed specifically to minimize operator involvement.
Given that the system is installed as described in earlier sections and is serviced
in accordance with the specified maintenance recommendations (see Service
Requirements), then it should simply be a matter of turning the air compressor on when
it is required.
The air compressor will automatically produce the factory set flow and pressure as
detailed in the Technical Specifications.

On Demand Gas
The air compressor system will produce compressed air on demand. If the application
is operating and requires a gas flow, the system it is connected to will supply this to suit
the requirements of the application. If the application requirement for gas stops, thesystem will also stop, once it has reached its upper set limit in the internal storage tanks.
If the demand from the application starts again, the system will detect the demand forgas and will automatically start again to suit the demand.

Unusual Operation
If at any time the air comrpessor begins to emit excessive noise or vibration, then it
should be switched off and you should contact Peak Scientific or the Peak Partner fromwhich the unit has been purchased.

Clean the outside of the unit 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 andthe power cord removed from the rear of the air compressor.

CAUTION

Under no circumstances should any solvents or abrasive cleaning
solutions be used as these can contain fumes that could be harmful tothe air compressor. Chlorine-based bleach cleaning solutions should not
be used on the air compressor or within its operating environment.

Care should be taken with Leak Detections Liquids.
