Installation
Generator Environment
The generator is designed for indoor use only. It should be installed adjacent to the
application 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 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 100mm (3.9”) 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 dimensions of the unit.
Please ensure Generator is situated in a well vetilated environment and is positioned to
allow easy disconnection from the mains supply if required
Minimum Operating Ambient Temperature:

5 °C (41 °F)

Maximum Operating Ambient Temperature:

30 °C (86 °F)

Drain Connection (MS Bench G SCI 1 & G SCI 2 Only)
Fit the 6mm push fit fitting to the drain port located on the output panel. Tighten
using a 16mm or 5/8” spanner. Use the 6mm tubing to connect this to a suitable drain
connection or container. It should be noted that the Generator can expel a considerable
amount of water from this (dependant on ambient humidity).

CAUTION

Page 20

If a container is used it should be emptied at regular intervals. The
container used MUST be a plastic material and MUST NOT be glass
for safety reasons. The container MUST NOT have an airtight seal as
water and air will be expelled periodically under slight pressure.

Electrical Connection
Connect the generator to an appropriate single-phase supply, refer to the generator
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 then
ensure 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, please
check the information on the serial plate. The mains supply must be of
the stated AC voltage and frequency.

Electrical requirements are 220 - 240v ±10% (MS Bench G SCI 1& G SCI 2) & 100 - 240v
±10% (MS Bench SCI 1 & SCI 2). Running 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 the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment maybe impaired.
WARNING

Page 21

Start-Up Sequence (MS Bench G SCI 1 & G SCI 2 Only)

CAUTION

Before the Generator is connected to the application, the Generator
should be operated in isolation (i.e. not connected to the application)
for thirty minutes. This is to ensure any impurities present are purged
from the system. Failure to do this may harm the application.

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. Once this pressure is reached,
the compressors will continue to run until the internal tank upper pressure limit is
reached and the compressor has run for a period of at least two minutes.
The compressors will then rest until the internal tank lower pressure limits is reached.
Once this limit is reached the compressors will switch back on again. This compressor
cycling is normal and will continue throughout the operation of the Generator.
When the system has been operated for a period of 30 minutes, all the internal pipework and storage tanks will have been purged with Nitrogen.
The Generator is now purged and the tubes can be connected at the rear of the unit.

Page 22

Connecting to the application (MS Bench G SCI 1 & G SCI 2 Only)
Once the initial purge run of 30 minutes has completed, and the generator has been
running for 15 mins, (required to reach purity for the application) it is ready to be
connected to the application(s)
The pressure in the internal storage tanks must be allowed to dissipate
before connecting the generator to the application(s)
CAUTION

Attach the ¼” compression fittings to the outlets of the generator. Using the ¼” tubing
supplied, connect the outlets of the generator to the inlets 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
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.

Note: Gauges are for indication purposes only.

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 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.

Page 23

Normal Operation (MS Bench G SCI 1 & G SCI 2 Only)
The generator 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 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 (MS Bench G SCI 1 & G SCI 2 Only)
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 the
applications requirements.

Generator Cycling (MS Bench G SCI 1 & G SCI 2 Only)
The generator is designed to operate in either a cyclic mode or run continuously, this
will be dependent on the output flow.
The cyclic rate of the compressors will depend on the gas demand of the application;
the generator will cycle when the upper tank pressure set limits are achieved within a
3-minute time period.
When the application demands increase, the compressor duty will be higher and the
rest period of the compressor cycle will be shorter. If operated at maximum flow, the
generator will run continuously to maintain the upper tank pressures. Another cause
for continuous operation would be if the generator is installed at high altitude, in an
extreme environment or subjected to low voltage supply. The compressors will undergo
periods where they do not cycle.

Unusual Operation (MS Bench G SCI 1 & G SCI 2 Only)
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.

Fan Power LED (MS Bench SCI 1 & SCI 2 Only)
The MS Bench Bench is fitted with a fan power LED on the front panel.
The LED should be illuminated when the table is supplied with power. This is indication
that the internal cooling fans are being supplied with power, and are running correctly.

Safe Operation of Pump Tray (MS Bench SCI 1 Only)
For safe installation or removal of roughing pumps, we recommend use of the sliding
function of the pump tray, as shown below.
This should only be attempted once the Mass Spec has been
positioned on top of the table.
WARNING

Remove the front panel, ensuring that the fan power is disconnected.
Depress both yellow tabs simultaneously and pull tray outwards until it clicks into
position.
Once pumps have been installed, ensure correct reconnection of the fan power lead.

Service Indication (MS Bench G SCI 1 & G SCI 2)
The generator has the following Service Indication Stages:-

Stage 1
Once either compressor requires a service the LED indicator (yellow) on the front of the
generator will illuminate.
This is to make the user aware that a service of the generator is due and should be
planned 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 4 weeks, the
service LED indicator (yellow) will start to flash.
This is to make the user aware that the service of the generator is now overdue and
must be completed immediately to ensure the continuous trouble free operation of the
generator.

Service Indication Reset
Once the service has been completed the Service Indication LED can be reset in the
main control PCB. This will be performed by the Peak Service Engineer or trained
service representative that completes the service operation.
