Page 11

Installation
Generator Environment
The generator is designed for indoor use only. It should be installed adjacent tothe application it is supplying. If this is not convenient then the unit can be sitedelsewhere, however, consideration should be made of the lengths of pipe runs aspressure drops can result from extended runs of pipe.
Performance of the generator (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 on the following page for the general dimensionsof the unit.
Minimum Operating Ambient Temperature:

5 °C (41 °F)

Maximum Operating Ambient Temperature:

35 °C (95 °F)

Page 12Generator Overview
General Dimensions

570 mm / 22.4”

870 mm / 34.2”

Drain Connection
Fit the 6mm push fit fitting (item 2 from fittings kit) to the drain port located on the
output panel (see Figure ). Tighten using a 16mm or 5/8” spanner. Use the 6mm tubing(item 4 from fittings kit) to connect this to a suitable drain connection or container.
It should be noted that the Generator can expel a considerable amount of water fromthis (dependant on ambient humidity).

CAUTION

Page 15

If a container is used it should be emptied at regular intervals.
The container must NOT have an air tight seal as water and air are
expelled at pressure.

Electrical Connection
Connect the generator to an appropriate 230 volt single-phase supply, refer to thegenerator serial plate for input specification and ensure your supply matches therequirements.
If the appropriate power cord is not supplied; a new plug, appropriately rated, can be
fitted by a qualified electrician.

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.

Our electrical requirements are 230VAC nominal +/- 10%. This means that theGenerator can accommodate transients between 207VAC and 253VAC. However,running continuously at voltages less than 220V is not recommended and extended
periods at these extremes can have a detrimental effect on the operation and lifeof the Generator. If the voltage supply is uncertain then a voltage check is highly
recommended.
If a substitute main supply cord is used, ensure that it has adequate rating. Failure to
do so could cause damage to the generator.

WARNING

Do not touch anything inside the Generator whilst the side panels are
removed and the mains power is connected to the unit

If the customer site is known to have a low power supply where the voltage reading is219V or less, then we would highly recommend fitting a Dual Tap Transformer
06-3210. This can be ordered directly from Peak Scientific.

Page 16

Start-Up Sequence

CAUTION

Before the Generator is connected to the application, the Generator
should be operated in isolation (i.e. not connected to the application)
until the light on the front cover illuminates green. This signifies thatthe purity of the output nitrogen is 99.5% and ensures any impurities
present are purged from the system. Failure to do this may harm theapplication.

Following the voltage check, the unit should be switched off and silencers fitted toeach of the three outlet ports of the output panel (ref Install Guide).
Once this is done, the Generator can be re-connected to the mains and switched on.
Pressure will start to build in the internal storage tanks which can be monitored bywatching the output pressure gauge on the front panel. This will climb to the factory
set pressure as noted in the specifications.
The Generator is now purged and the tubes can be connected at the rear of the unit.

Page 17

Connecting to the application
Once the initial purge run has completed, the generator is ready to be connected tothe application(s)The pressure in the internal storage tanks must be allowed todissipate before connecting the generator to the application(s)CAUTION

Attach either the 6mm elbow or ¼” compression fitting to the outlet of the Generator.
Using the 6mm or ¼” tubing supplied, connect the outlet of the Generator 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 itis thoroughly checked for being leak-tight. Even the slightest leak in
the gas supply between the generator and the application can lead toa reduction in efficiency.

Tubing Lengths

CAUTION

The diameter of the tubing which will be connected to the gas outlets
is important and is determined by the length of tubing required.
Failure to follow these recommendations could lead to pressure
between generator and application.

< 10 meters:		

Use 6/4 (6mm O/D, 4mm I/D) P.T.F.E. tubing.

> 10 - 40 meters: Use 10/8 (10mm O/D, 8mm 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 6/4 and 10/8 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 10/8
and the final 10 meters to the application use 6/4 tubing). Keep the connections andbends to a minimum.
The imperial equivalents are: 6/4 = 1/4” O/D, 3/16” I/D.
10/8 = 3/8” O/D, 5/16” I/D.

Page 18

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

On Demand Gas
When the application requires a gas flow, the generator will produce gas on demand.
The generator will continue to supply gas whilst the application is in a ‘Standby’ mode.
As soon as a demand is detected from the application, the generator will match theapplications requirements.

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.

the generator will illuminate.
This is to make the user aware that a service of the generator is due and should beplanned at the earliest convenience. The generator will continue to operate as normal
with the LED on.

Stage 2
If the service is not completed the generator will continue to run. After 2 weeks, theservice LED indicator (yellow) will start to flash.
This is to make the user aware that the service of the generator is now overdue andmust be completed immediately to ensure the continuous trouble free operation of
the generator.

Service Indication Reset
