Installation
Generator Environment
The generator is designed for indoor use only. It should be installed adjacent to
the application(s) it is supplying. If this is not convenient then the unit can be sited
elsewhere. Consideration should be made of the lengths of pipe runs as pressure drops
can result from extended runs of pipe. See page 21 for guidance on tubing lengths
greater than 3m.
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. An air gap of 75mm (3”) should be maintained down both sides.
Please refer to the drawing opposite for the general dimensions of the unit.
Please ensure generator is situated in a well ventilated environment and is positioned to
permit easy disconnection if required.
Minimum Operating Ambient Temperature:
5 °C (41 °F)
Maximum Operating Ambient Temperature:
35 °C (95 °F)
Please note that the generator’s function is primarily to remove Oxygen and Moisture
from the generated Nitrogen and/or Dry Air. Depending on model, some hydrocarbon
technology may be employed by the generator, in environments with high ambient
concentrations of THC additional THC removal filtration may be required, or service life
of integrated THC traps may be significantly reduced.
Operation in High Ambient Temperatures
Horizen generators are designed to supply the rated flow, purity, and pressure in
most laboratory environments, however high ambient temperatures can affect the
performance of the generator. Output flow capabilities may be restricted in high
ambient temperatures, or areas with insufficient air circulation.

Drain Connection
Fit the 6mm push fit fitting to the drain port at the rear of the unit.
Tighten using a 12mm or 1/2” 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 (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. The container
must be placed at ground level with no elevated or spiralled tubing.Fix
the drain ending of the tube firmly to prevent it from vibrating during
draining.
Electrical Connection
Connect the generator to any voltage 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
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.

WARNING
Page 21
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)
for thirty minutes. This is to ensure any impurities present are purged
from the system. Failure to do this may harm the application.
Before connecting the generator to the mains and switching it on for the purge run, it is
necessary to fit the silencer to the nitrogen output port.
Once this is done, the generator can be connected to the mains and switched on.
The Horizen will then go through Product Registration. This is detailed on the next page.
Continue to operate the generator for a further 30 minutes to allow all the system to be
purged with Nitrogen.
The generator is now purged, the silencer can be removed and the tubes can be
connected at the rear of the unit.
Page 22
Product Registration
Before the generator will start-up for the first time the user must enter a unique 4-digit
PIN code.
To receive your generator’s unique PIN code, please register on the Peak
website www.peakscientific.com/activate or download the Peak mobile
app from the Google Play Store or Apple App Store. A PIN code may also
be requested by phoning the Peak helpdesk.
This code is only required on the initial start-up of the unit.
Horizen 24 Registration
1. Press the 'I've got my pin' button on the screen on the front of the generator.
2. Enter your PIN.
3. The unit will then go through initialisation phase
Page 23
4. Upon completion of the initialisation phase, the screen will display the below, home
screen.
Page 24
Connecting to the application
Once the initial purge run of 30 minutes has completed, it is ready to be connected to
the application(s).
CAUTION
The pressure in the system must be allowed to dissipate before
connecting the generator to the application(s). This may be done by
leaving the Nitrogen port at the rear of the generator open, pressing
Turn Off on the HMI home screen and turning off the power supply to
the generator.
Select the appropriate 1/4" or 6mm fitting from the fittings kit and connect to the
generator outlet. Using the appropriate tubing, 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 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 drop in Nitrogen purity or insufficient pressure.
Tubing Lengths
CAUTION
The diameter of the tubing which will be connected to the gas outlet is
important and is determined by the length of tubing required. Failure
to follow these recommendations could lead could lead to excessive
pressure drops between generator and application.
< 3 meters:
> 3-10 meters:
Use 6mm OD / 4mm ID or 1/4” OD / 3/16” ID PTFE tubing.
Use 8mm OD / 6mm ID or 5/16” OD / 1/4” ID PTFE tubing.
Tubing and fittings not supplied in the fittings kit.
> 10 - 40 meters: Use 10mm OD / 8mm ID or 3/8” OD / 5/16” ID PTFE tubing.
Tubing and fittings not supplied in the fittings kit.
> 40 metres:
Page 25
Please contact Peak Scientific with the relevant distance and
we will calculate the flow resistance and the tubing size required.
Setting the output pressure
The output pressure is factory set to 100psi, however; the generator can deliver Nitrogen
at the rated flow up to a maximum pressure of 116psi. The output pressure can be adjusted
using the pressure settings function on the HMI home screen.
To ensure a smooth pressure profile, it is not recommended to increase the output pressure
above 116 psi.
Page 26
Normal Operation
The generator requires minimal operator input. So long as the generator is installed as
described in earlier sections and is serviced in accordance with the specified maintenance recommendations (see Service Requirements), then it will operate in accordance
with the demands of connected applications.
The generator will automatically produce the factory set pressure of 100psi. The outlet
flow rate will vary to satisfy customer demand up to a maximum flow rate in normal
operating conditions of 24 LPM.
The generator is a variable-purity system, and will supply a higher purity of nitrogen at
lower flow rates, with a minimum purity of 95% nitrogen at the maximum rated output
flow.
Home Screen
This is the main home screen in normal operation.
Variable Power Output
When demand from the instrument stops the Horizen generator will run in a reduced
power state to reduce energy consumption and minimise component wear.
If demand from the application starts again, the system will detect the demand for gas
and will automatically increase workload to match the flow requirement.

Service Indication
The generator will notify the user of the service interval for the internal compressor.
The generator has the following Service Indication Stages:-
Stage 1
12 months after installation, the service indicator will show on the display.
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 service indicator on. If the warning message has been acknowledged, the icon
will still be displayed in the corner of the HMI; pressing the icon will take the user to the
error page.
Stage 2
If the service is not completed the generator will continue to run. After 2 weeks, the
service overdue indicator will show on the display.
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. If the warning message has been acknowledged, the icon will still be
displayed in the corner of the HMI; pressing the icon will take the user to the error page.
Service Indication Reset
Once the service has been completed the Service Indication can be reset through the
service interface. This will be performed by the Peak Service Engineer or trained service
representative that completes the service operation.
