6 INTRODUCTION
The M&C BA-C air conditioning unit has been designed especially for applications where dry, cleaned
and hydrocarbon-free air is required, independent of gas cylinders.
Typical applications are hydrocarbon measurements with flame ionisation detectors (FID) and use as
a zero gas generator for the calibration of infrared (IR) analyzers or for production of dilution gas for
M&C dilution probes.
The M&C BA-C air conditioning units are compact, operator and service-friendly 19” plug-in units for
19”-rack mounting or wall mounting.

being switched and purged resp. regenerated cyclical.
The inlet pressure is 70 - 145 psig. The manometer P1 on the front plate of the BA-C enables the
optical control of the inlet pressure.
The cleaned air is available at the outlet 2. Here a connector G ¼“ i provided by customer can be
mounted.
If the inlet pressure drops to a value below 73 psi or the catalyst temperature falls below 914°F the
gas flow is switched off.

All controls and indicating elements are arranged easily accessible on the front panel of the
combustion air conditioning unit:
P1: Inlet pressure gauge P1
S1: Main switch S1
B1: Temperature controller with digital temperature display B1
The M&C air conditioning unit BA-C is a compact, easy to handle and maintain wall mounting device.
By rebuilding the mounting brackets the air conditioning unit is also applicable for 19“-rack mounting.
The gas connections at the back (G 1/4“i) can be used for the 19“-mounting and the gas connections
on the top can be used for wall mounting. The electrical connections take place via the fix connected
3m cable at the side of the housing.
The oven temperature is electronically controlled and preset at the factory to +932 °F at the
temperature controller B1 on the front panel.
Remaining the catalyst temperature by 50 °F or the minimum inlet pressure of 73 psi will switch of the
gas flow.

NOTE!
The air conditioning unit should be stored protected from frost!
NOTE!
The air conditioning unit must only be used in the conditions specified in
the technical data.
The air conditioning unit should be installed away from heat sources and
freely ventilated to prevent any accumulation of heat.
For outdoor installation, the air conditioning unit must be installed in a
housing protected from frost in the winter and sufficiently ventilated in
summer. Exposure to direct sunlight must be avoided.
At the inlet of the device (upstream the filter) a shut off valve shall be
provided
10 RECEIPT AND STORAGE
The BA-C combustion air conditioning unit is a complete, pre-installed unit. The standard catalyst
and adsorber cartridge supplied is already fitted. The filter to be connected upstream is attatched to
the device.
Immediately remove the air conditioning unit and any special accessories carefully from the
packaging and check the contents against the delivery note.
Inspect the unit for possible transport damage and inform the transport insurer concerned
immediately if any damage is noticed.
11 INSTALLATION NOTES

WARNING!
The input compressed air has to be dry and oil free, because
otherwise the device will be damaged!
19“-Mounting
11.1 REBUILDING FOR 19“-RACK-MOUNTING
The deliverd device is prepared for wall mounting.
For 19“-rack-mounting the two mounting brackets have to be disconnected from the back side and
fixed to the front side.
For one side as a start act as follows:
Unscrew the three screws at the front of the sidewall.
Unsrew the two upper screws at the mounting bracket and only loosen the third to turn the
bracket to the back. Screw in now the two screws again.
Unscrew the lower screw from the bracket and screw it in without the bracket.
Fix the bracket at the front.
Do it the same way at the other side.
This procedure ensures that the back wall remains fixed in the device.

12 SUPPLY CONNECTIONS
12.1 MOUNTING AND CONNECTION OF THE FILTER
The separate delivered filter has to be mounted at an easy accessible place and has to be connected
with the inlet of the air conditioning unit. For the filter housing a minimum constructional size of
100mm has to be taken into consideration.
For the connection between filter and the inlet of the conditioning unit two connectors G ¼“-DN4/6
and 2m PTFE tube are enclosed to the delivery. The filter inlet is marked with 1 and the outlet is
marked with 2.
Gas sampling and gas conditioning technology 10-1.1.1-ME
12
HINWEIS!
Do not exchange the tube connections for inlet and outlet; the
connections are marked correspondingly.
1 = inlet; 2 = outlet
After connecting all tubings, check the closeness.
WARNING!
Incorrect system voltage can damage the unit. When establishing
connections, check that the system voltage corresponds with the
voltage shown on the type plate!
NOTE!
For the erection of power installations with rated voltages up to
1000V, the requirements of VDE 0100 and relevant standards and
specifications must be observed!
The main circuit is equipped with a fuse corresponding to the
nominal current (over current protection); for electrical details see
technical data.
12.2 HOSE CONNECTIONS
The connection of the air in- and outlet take place on the top for wall mounting and at the back side
for 19“-rack-mounting.
19“-Mounting Wall mounting

For rebuilding the connections (G1/4“i) on the top or back side the blind plugs have to be displaced
correspondingly.
— Appropriate connection fittings are optionally available by M&C
12.3 ELECTRICAL CONNECTIONS
The mains connection takes place via the fixed installed 3m mains cable:
brown = L
blue = N
green/yellow = PE
The connection of the status alarm NO takes place via the fixed installed 3m twin core cable.

WARNING!
The air conditioning unit is operated with min. 73 psi and max.
145 psi inlet pressure.
NOTE!
The maximum gas flow is 15Nl/min.
NOTE!
The place of installation of the air conditioning unit must be
remain free from frost also during time when the unit is switched
off !
WARNING!
The air conditioning is operated with max. 145 psi inlet pressure.
High voltage and high pressure. Disconnect the mains plug and
the pressure air inlet before opening the housing!
13 INITIAL OPERATION
Prior to initial operation, the system and process-specific safety measures must be observed !
The following steps must be carried out prior to initial operation:
Prior to initial operation, compare the system voltage with the voltage shown on the rating plate;
Connect the air conditioning unit to the mains;
Connect status contact ouput, if necessary ;
Operate the “Power/On” switch (green LED lights).
Check the nominal temperature of 500°C at the temperature controller (see Figure 2).
When operational readiness has been reached (about 15 minutes), the 1 lights upin the display.
14 SWITCH OFF
Switch off the device and disconnect the pressure air.
No more particular measures are required for switch off.
15 MAINTENANCE
Before carrying out maintenance work, the system and process-specific safety measures must be
observed!
Gas sampling and gas conditioning technology 10-1.1.1-ME
14
WARNING!
Also after switching off the mains voltage touching the catalyst
cartridge can lead to serious burns. Wear protective gloves.
WARNING!
The air conditioning is operated with max. 145 psi inlet pressure.
Before maintaining the filter the device has to be disconnected
from the pressure air.
WARNING!
At a condensate level of 10mm below the Filterelement (see
marking) the condensate has to be drained because otherwise the
air conditioning will be damaged.
15.1 THE EXTERNAL PARTICLE-CONDENSATE-FILTER
15.1.1 DRAIN OF THE CONDENSATE
Disconnect the device from the pressure air supply.
Open drain screw anti clockwise seen from below.
Condensate is draining off.
For the condensate connection a hose connector for tube 4/6mm is exsisting.
15.1.2 CHANGE OF THE FILTER CARTRIDGE
Changing the filter cartridge may be necessary in case of decreasing air flow.
For a change of the filter cartridge the following steps must be carried out:
Disconnect pressure air from the filter
Wait until the pressure in the device has decreased to ambient pressure (control at the
manometer)
Push unlock slider in direction of the arrow
Turn filter housing anti clockwise (seen from below) and remove it downwards
Turn filter cartridge anti clockwise
Touch new filter cartridge only at the lower end
