Chapter 2 Unpacking and Installation
Installation
Selecting a Location
When choosing the location for the MiniCapt Remote Microbial Air Sampler(s),
consider the following bulleted list of suggestions to improve the utility of the unit.
•
Sample Point
Position the sampler to ensure that the BioCapt Impactor sampling head is pointed
toward the airflow.
• Requirements for sample tubing selections:
Table 2-3
Sample Tubing Dimension Requirements
Model
Total Maximum
Tubing Length
Minimum Inner
Diameter
25/50 LPM
5 m (16.4 ft)
1.27 cm (0.5 in)
100 LPM
3 m (9.8 ft)
1.905 cm (0.75 in)
The Total Maximum Tubing Length indicates the total amount of tubing, including
inlet and exhaust.
If other flow restrictions (e.g. connections with smaller inner diameters) are
integrated into the setup, the tubing length needs to be reduced accordingly. The
total pressure drop caused by tubing or other restrictions should not exceed 4 inH
2
O
(0.01 bar, 1 kPa). Exceeding this restriction will cause a decreased flow through the
sample chamber, resulting in flow alarms.
•
Accessibility
The unit should be readily accessible for connecting and disconnecting cables,
removal for calibration, and so on.
NOTE:
The main power disconnect is the power cord. Ensure that it is
easily accessible.
•
Interference with existing equipment
The unit should not interfere with access to existing or known future equipment
installations.
•
Visibility
The unit’s front panel should be visible from a reasonable position to allow easy
viewing of the
Status
and
Power
LEDs.
•
Mounting surfaces
– The proposed mounting surface should allow mounting
hardware to engage properly and should be of sufficient strength to support the unit
safely.
•
Cables
The unit should be located near a source of grounded electrical power, an Ethernet
port, and any other devices it must communicate with. Cables should reach from the
unit to the connector without strain.
