Technical Specification!
!
Please refer to the MicroBio Manual P0001W003 for full detailed specification of the
MicroBio MB2.!
!
The MB2-RSH model is capable of driving a remote sampling fan up to a distance of 20m
from the control unit.!
!
Installation!
!
The first task is to run the connecting cable from where the sampling head is to be
positioned to where the control unit is to be located.!
!
Two cable options can be supplied. One is with an extension cable with connectors at
each end, the other with one of the connectors not fitted. By not terminating one of the
connectors enables the cable to be passed through glands or bulkheads as required by
the end user. Once the cable is routed, the unterminated end, located where the control
unit is, must have the supplied locking connector fitted. Note that the pre-fitted connector
on the extension cable, then end labelled “RSH”, must be where the remote sampling
head is located. !
!
Fitting the Connector for Unterminated Cables!
!
The following tools are required to fit the connector:!
!
1 x Soldering iron and solder (lead free)!
1 x 2.5mm slot screwdriver!
!
The connector is assembled in the order as shown in the photographs below.!
!
1. Dismantle the connector by first removing the screw on the side of the connector.#

2. Fit connector housing and strain relief onto cable end.#
!
3. Remove cable clamp.#
!
4. FIt frame onto cable end and refit cable clamp.#

5. Solder cable onto connector pins. The connector body has pin numbers embossed onto
the surface adjacent to the pins.#
!
i. Pin 1: Red!
ii. Pin 2: Blue!
iii. Pin 3: Screen#
!
6. Fit pin housing back into frame noting that there are raised pegs on the rim of the pin
housing that sit into holes on the frame. Then replace frame cover.#

7. Slide the assembly, strain relief and metal shell together.#
#
!
8. Align shell so that the brass thread of the frame body can be seen, then replace the
housing screw and tighten.#

Connecting the Control Unit and remote Sampling Head!
!
Now position the remote sampling head and connect the fly lead on this to the extension
cable end labelled “RSH”. The connectors have a screw locking mechanism. Screw the
two halves together by twisting the outer ring of the plug from the the remote sampling
head connector into the cable socket on the extension cable. Take care not to cross
thread.!
!
The remote sampling head!
!
!
Now connect the other end of the extension cable labelled “CTRL” into the rear of the
control unit.!

Calibration!
!
The MB2-RSH can be calibrated in the same manner as any other MicroBio bioaerosol
sampler.!
!
Remove the remote sampling head from its normal location, disconnect the extension
cable from the control unit and then plug the remote sampling head directly into the control
unit as below:!
!
If extension cables over 10m in length are used, then it is recommended that the sampler
is calibrated with a cable of the installed length fitted to compensate for any voltage drops
on longer cables.!
!
For calibration specifics, please refer to document P0001W002 for calibration methodology
or if using the P0059 Validation Kit, refer to P0059W003.!

Operation!
!
Once installed, the MB2-RSH operates in exactly the same way as a conventional MB2
bioaerosol sampler.!
!
For operation instructions, please refer to the MicroBio Manual, document number
P0001W003.!
!
!
!
Cleaning and bio-decontamination!
!
The control unit and the remote sampling head may both be cleaned using conventional
sanitising wipes, such as Tuffie-5 or 70% IPA.!
!
As the remote sampling head will normally be fixed within a compartment, it is suitable for
use with Hydrogen Peroxide Vapour (H2O2 vapour) bio-decontamination.!
!
Tests have been carried out by Bioquell (UK) Ltd on sensitive electronic equipment to
determine effects of such processes. The conditions of these tests were:!
!
!Gas Concentration! ! 1000 ppm!
!Conditioning time! ! 20 minutes!
!Gassing time!!!30 minutes! !
!Aeration time!!!150 minutes!
!
As the MicroBio MB2-RSH has a fan within the remote head it is recommended that during
the decontamination process the MicroBio MB2-RSH is set to sample 2000 litres several
times so that the H2O2 vapour may be drawn through the head, fan and exhaust for
optimum decontamination.!
!
Throughout the trials, Bioquell demonstrated that bio-decontamination with H2O2 vapour
does not appear to be detrimental in any way, effect operational aspects or aesthetics of
sensitive electronic equipment.!
!
As the control panel will not normally be exposed to bio-contaminants as the remote head,
cleaning using sanitising wipes may suffice, but it is also suitable for use within H2O2
vapour environments.!
!
