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’ 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
two people to remove the unit from the shipping crate and to manoeuvre the
Generator onto the floor.
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 and US also all the required fittings. Be careful not to discard
these with the packaging.

Unpacking Instructions
The PG 14L and 28L generator weigh approximately 14.4 and 18.6 Kg,
respectively, and as such should only be lifted using safe lifting practice.
1.

Open packaging, and remove foam.

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

Installation
Generator Environment

The Purge Gas Generator is designed for indoor use only. For
safety reasons, the unit requires to be wall mounted on a
steady and level surface. Please see enclosed Installation Guide
in the product packaging for correct installation instructions.
The minimum and maximum ambient operating temperatures are 5oC and 25oC.
Keep the unit in a well ventilated site away from direct sunlight.

Voltage and Power
The PG14/28L are fitted with an internal switch mode power
supply that will accept a power inlet from 100VAC - 240VAC,
50/60HZ. The current consumption is 80 mA.
Please ensure generator is positioned so as to permit easy disconnection if
required.

Electrical Connection
Connect the Generator to an appropriate 110 - 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 12
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.

Electrical requirements are 110 - 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.
If a substitute main supply cord is used, ensure that it has an adequate rating.
Failure to do so could cause damage to the generator.
The PG14/28L are fitted with an internal switch mode power
supply that will accept a power inlet from 100VAC - 240VAC,
50/60HZ. The current consumption is 80 mA.

Start-up Procedure
Connect the fitting to the input of the filter on the generator and connect to
your in house air supply. Restrict output to the manufacturer specification.
Ensure that the power to the Purge Gas Generator is turned on before starting
the air supply. Gradually introduce air pressure to the unit until the
recommended pressure has been reached.
Allow unit to vent to atmosphere for 16 hours before connecting to any
equipment.
The system is now operational and requires no further intervention.

thing on your mind- but it is very important to both of us. Not all warranties are
alike and Peak Scientific stand out against other gas suppliers as we offer a
comprehensive, quick response, on-site warranty. This means that in the very
unlikely case that your gas generator develops a fault we have rapid support teams
on-hand around the world who are able to come to your lab and get you back up
and running in no time.
Register for your comprehensive 12 month on-site warranty with ease online at
www.peakscientific.com/register.
Alternatively, you can send the completed form to Peak Scientific by post or email
at warranty@peakscientific.com.

Important!
You have 1 month to register your Peak Scientific product from the date of
installation. Once registered the warranty will be honoured for a period of 12
months. If you wish to defer the installation of your generator, you must notify Peak
Scientific immediately by emailing warranty@peakscientific.com. For generators
that remain unregistered after 1 month from the shipment date, the warranty will be
considered active from the date of factory dispatch.

Normal Operation
Principal of Operation
The Purge Gas Generator works using Pressure Swing Adsorption (PSA).

PSA works on the principle that an adsorbent (such as the activated alumina
used in the PG series) has a differential adsorbing capacity at high and low
pressure. The Purge Gas Generator consists of two columns of adsorbent, one
at high pressure which adsorbs CO2 and moisture from compressed air, and
another at low pressure. The low-pressure column is fed with a slipstream of
the moisture and CO2-free air, known as the purge flow. This purge flow assists
in the regeneration of the adsorbent. After a fixed time, known as the “swing
time”, the high-pressure column depressurises and the pressure increases in the
low-pressure column. What was the low-pressure, regenerating column, then
assumes the role of the high-pressure adsorbing column, with the high pressure
column adopting the role of the low pressure, regenerating column. This
reversal of the roles of the columns can continue indefinitely rendering the
adsorbent columns maintenance free.

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.
Under no circumstances should any solvents or abrasive
cleaning solutions be used as these can contain fumes that
could be harmful to the Generator.

Service Requirements
Routine Maintenance
Servicing and/or repair of the Generator should only be
undertaken by a TECHNICALLY COMPETENT PERSON, with the
generator in its safely isolated condition.
Safely Isolated Condition; The unit is in a Safely Isolated
Condition when it is disconnected from its application, fully depressurised and isolated from the Electrical Supply. Directions
for isolating the generator are shown below.

Isolating the Generator
a. Switch off the unit.
b. Disconnect the unit from the mains supply.
c. Disconnect from the application.
