2. INTRODUCTION
This manual is an integral part of the product. The manual describes the installation and maintenance
operations as well as user modes and troubleshooting.
Contents
Read the manual carefully before starting up the Mini Whisper and familiarize yourself with its content.
Modications
Do not make any modications to the Mini Whisper unless explicit written permission has been given by the
manufacturer. If such modications are made without the manufacturer’s consent, the manufacturer denies any

2.1. Functionality
The Mini Whisper separates compressed air into pure nitrogen and oxygen-enriched air. The separation
system is based on a special membrane technology.

3. SAFETY
3.1. Personal Safety Instructions
The Mini Whisper is a nitrogen generator. Do not operate the generator with the nitrogen outlet
open in a small or not sufciently ventilated room. An increase of the nitrogen and a decrease of
the oxygen concentration in the air may cause health problems. It is the responsibility of the user to
check whether the room is appropriate or an O2measurement is necessary.
3.2. Instrument Safety Instructions
The Mini Whisper ejects oxygen as waste. Oxygen concentration in the air could change around the
generator in a small or not sufciently ventilated room. If fuel gases are present, their explosive or
ammable limits could be affected.
3.3. Warning
• The quantity of dust in the ambient Air can be very different from one place to
another. We recommend replacement of the dust lters every 4000 hours. In
some dusty areas, this maintenance needs to be performed more frequently.
• Clogged dust lters may damage the generator or give a bad Nitrogen quality.
• If the Mini Whisper is used in a way not specied by VICI DBS, the protection
provided by the equipment could be compromised.

Version 1.03.0000
A special characteristic of the Mini Whisper is the momentary stop of the compressor if the LCMS is not using
Nitrogen. This momentary stop is regulated by a pneumatic control valve pre-calibrated by VICI DBS. This will
extend the life span of the compressor and at the same time help save energy.

ACompressed Air Input BHollow Fiber Membrane CNitrogen Output
Atmospheric air contains nitrogen (78.1%), oxygen (20.9%), argon (1%), carbon dioxide, water vapor, and
traces of inert gases. The compressed air (A) is forced through the hollow ber membrane (B). The various
components of the air permeate the porous membrane walls.

7
MINI WHISPER
USER MANUAL www.vicidbs.com
Version 1.03.0000
The speed of permeation varies from gas to gas:
• Oxygen and water vapor have a high permeation speed and pass quickly through the membrane wall
• Nitrogen has a slow permeation speed and passes slowly through the membrane wall
• The resulting Nitrogen ow (C) is then forced out of the membrane and used directly

5. INSTALLATION
5.1. Transport
Transport the Mini Whisper without tipping it.
Transport the Mini Whisper in the original packing.
5.2. Location
Install the Mini Whisper in an area with the following characteristics:
• Minimum distance of 20 cm at the front and lateral sides to allow sufcient cooling
• An enclosed (indoor), dry room
• Avoid direct sunlight
• Keep away from heat sources
• Room with adequate aeration/ventilation
• Connect a tube for waste humidity from lters “B” and “C”
5.3. Connecting the Mini Whisper to the LC-MS
ATTENTION: Check that the tubing connecting the Mini Whisper and the LC-MS is free from dust, grease,
drops of liquid etc., before making the connection. Connect the Mini Whisper and the LC-MS with stainless
steel tubing.
6. OPERATION
6.1. Starting the Unit
1. Connect the Air Inlet “B” (page 7) to the air supply line from the compressor (oil free!)
2. Install a piece of tubing from the nitrogen outlet to the LC-MS or another equipment using nitrogen
3. Slowly open the red tap upstream from the coalescent lter “B”
4. Slowly open the red taps from the air outlets
5. The generator is ready to be used
