Inspect Shipment for Damage
Carefully inspect the entire shipment fordamage in the presence of the shipper’s agent,
removing packaging material if necessary. Note any damage to packaging and/or goods on
Packing List andhave it signed by the shipper’s agent prior to accepting the shipment. Submit
damage claim to MRU immediately.
NOTE: Damage claims not received by MRU within 3 days of receipt of shipment will not be
accepted.
Important notice!
This high quality electronic analyzer utilizes batteries that discharge even when the analyzer is
not in use. Therefore itis very important to charge the batteries (Li-Ion) every 4 - 6 weeks, even
if the analyzer is not in use.
Failing to properly charge the batteries will void your warranty!
Save the original box and the packing material for use if the analyzer must be shipped in the
future.
The products described in this manual are subject to continuous development and improvement
and it is therefore acknowledged that thismanual may contain errors or omissions.MRU

1. General information
1.1. The company MRU GmbH
Your analyzer is produced by the MRU GmbH in Neckarsulm Germany (founded in 1984), a
medium sized company that specializes in developing, producing and marketing high quality
emission monitoring analyzers. MRU GmbH produces a wide range of instruments, from
standard analyzers up to tailor made industrial analyzers. MRU GmbH contact details are listed
on the previous page.
1.2. Important general information (EN 50379) and VDI 4206
This analyzer is not designed to be used forcontinuous measurements.
Before using the analyzer verify the condition of the various parts of the analyzer, such as the
probe, the ambient air conditions, the condensate separator, star filter and the connectors for
damage and/or blockages.
When starting up the analyzer it will take between 1 – 3 minutes to set to zero depending on the
condition of the sensors and of ambient.
The minimum zeroing time of the analyzer to achieve correct measurement values can be
expected by 1.5 minutes!
Caution: Exposure to acids; aggressive gases such as sulphur; vapours such as thinners,
gasoline, alcohol and paint, etc. can damage, reduce the life of, or destroy the sensors.
The life of the sensors depends on how they are used, maintained and treated. Typical average
life expectations are: O2- 2 years; CO - 2 - 3 years and NO - 3 years.
The use of the analyzer for regulatory purposes is subject to special regulations (for example a
periodical examination of the analyzer). Please obtain the appropriate regulations from your
local responsible authority.
The battery life is at least 500 charge-discharge cycles. With increasing number of cycles is
reduced specified in the technical data devices operating time per battery charge.
1.3. Important information about the users/operation manual
The users/operation manual is an important part of this delivery. It will explain how to use this
analyzer properly and sets forth safety and environmentally friendly procedures.
It is the responsibility of all users to read and familiarize themselves with this manual, paying
particular attention to the safety instructions.

The most important safety details are clearly marked withan attention sign.
1.4. Safety Information
The following safety procedures must to be followed at all times. They are a significant and
essential part of this manual. Failure to follow safety procedures can result in the loss of your
warranty claims.
Safety regulations
The analyzer mayonly be used as indicated in this manual. Our analyzers are checked
according to the following regulations:
VDE 0411 (EN61010) and DIN VDE 0701 before they leave the MRU GmbH factory.
MRU technicalproducts are designed and manufactured accordingto DIN 31000/ VDE 1000
and UVV = VBG 4 of the professional guilds for fine mechanics and electrical engineering.
MRU GmbH assures that the analyzer complies to the essential requirements of the legal
regulations of themember states of the electro-magnetic compatibility (89/336/EWG) and to the
low-voltage regulations (3/23/EWG).
Specific safety regulations
Use only the battery chargersupplied with the analyzer for this instrument.
No part of the analyzer, including the metalprobe tube and all othermetal parts & accessories
are to be usedas electric conductors.
The analyzer is not to be used in or under water.
The analyzer is not to be placed near or directly exposed toopen fire or heat.
The specified probe temperature range is notto be exceeded, as theprobe, temperature
sensory mechanism and sensor could be damaged or destroyed.
The analyzer shall void dropping.
Attention:
Caution: Moisture, being pumped out of thecondensates trap can be slightly acidic.
In case of skin contact IMMEDIATELY: clean affected parts of the body.
Avoid getting liquid in eyes.
Please carefully clean all parts that come into contactwith the condensates.
After measurement, vent the analyzer with ambient air and allow the probe to cool.
A hot probe could cause burnsor ignite flammable material.
Electrochemical sensors are by their operating principle not onlysensitive to the gas theyare
intended for, but for other gases as well. This cross sensitivity iscompensatedby MRUfor the
typical application of flue gas analysis. However, unusual high concentration levels of single gas
components might lead to a reduced measurement accuracy of other gas components and to a
temporary change of thesensitivity of sensors, which may require several hours recoverytime.
Especially concentrationlevels as high as several% for single gascomponents may affect the
measurement of other gas components at ppm level.
Those applications need tobe discussed with MRUin detail.

2. Analyzer description
2.1. Introduction
The main task of the NOVAcompact gas analyzer is in supporting the following applications:
•Precise control- and adjustment measurements for Gas- , oil or wood fired burners
•Flue gas measurement according to 1. BImSchV and KÜO (German regulations)
This analyzer can be equipped with additional options and/or additional accessories to full fill
multiple other measuring tasks such as
•Measurements at CHP's (cogeneration heat and power engines) with CO-sensor protection
by means of a Purafil filter
•Proof of sufficient combustion air supply „4 Pa – test“
•Anemometer (Option Flow velocity, using either a Pitot tube or a vane)
•Differential measurements of pressure and temperature
•Mobile Gas detector (Option HC-sniffer)
•Leak testing device (Option external pressure sensor)
The multiple options and multiple connections possibilities of external sensors often replaces
the need of additional measuring equipment(s). Ask oursales reps. for available options and
accessories or check out our MRU website.
2.2. Gas flow diagram
In combination with the sample gas probe, analyzer filtered off a partial volume of sample gas
from the combustion channel, and analyzes it by means of electrochemical sensors on its
ingredients.
Pressure (draft) and temperature are measured by the design of the exhaust probe directly at
the probe tip.

2.5. Condensate separator
Disconnect the hoses at the gas entrance port (1) and the gas exit port (2).
Lift the condensate separator upwards out of the mounting bracket next to the base unit.
Liquid that is poured out of the condensate separator can be lightly acidic.
The condensate show glass and the bottom plug are screwed into each other and can easily be
taken apart from each other (for cleaning and drying the condensate separator). He filter
housing can also be unscrewed to replace the pleated filter. Please pay special attention when
reassembling the condensate separator that all the O-Rings are in the right position and that
they are not damaged. After each dismounting of the condensate separator we recommend you
to perform an instruments leak proof test.
There is a pleated filter mounted in the condensate separator. This filter filters rough particles
out of the flue gas. This pleated filter is washable and can be reused up to five times (filter must
be completely dry before being used again). The filter should be replaced or washed when it
changes its color from to brown or grey. A frequently washed or replaced filter will avoid dirt
getting inside the analyzer will therefore avoid damage toyour analyzer.
