PhenoMaster | Hardware Operating Instructions
•
Vacuum pumps (pull principle respirometry, underpressure principle)
o
Under no circumstances you should grease or oil the pump!
o
Choking the air flow by reducing the outlet or closing it leads to premature wear of the
pump. If the air flow fails, the windings overheat and burn.
•
Mass Flow Controllers
The mass flow controllers of the Control Units are intended for measuring and controlling air
only. Oil-free air must be used only. The pump supplied must be used only; do NOT use
compressed air generators.
•
Reference air
o
No rapid alteration in the CO2 or O2 concentration of the reference air should take
place during the measurement, as this will cause inaccurate results.
o
No O2 consumers or CO2 generators should be located in the air from which the
reference air is taken.
o
The reference air should be taken from the same location as that used for the air
supply pump.
•
When the High-Speed Sensor Unit is in operating mode, ensure that sensors are supplied with
reference gas to protect device against contamination.
2.6. Ambient Conditions
The system must be operated in locations only which satisfy the following ambient conditions.
•
Setup in a closed room.
•
Fresh air supply required.
•
Dry location; don´t store liquids above the system devices. Keep all surfaces (e.g. floors) dry.
•
Protect against water splashes.
•
Solid, level, and nonflammable support.
•
The ambient temperature must be >=15°C (>=59°F) and <=25°C (<=77°F). The animal cages
alone can be placed in a climate chamber with temperatures >=3°C (>=37.4°F) and <=30°C
(<=86°F) but the Control Units and the PC must be placed outside close to that chamber
under normal environmental conditions.
NOTICE
- Measurement errors!
If the air is very humid, this will affect the measuring accuracy of the MFC.
Do NOT operate Process Control Units and Air Drying Unit with non-ambient temperatures (<15°C
(<59°F) or >25°C (>77°F)).
•
The relative humidity of the surroundings must NOT exceed 60% (non-condensing).
•
The system must NOT be exposed to direct sunlight or radiated heat.
•
The system must NOT be located directly beside or above sources of heat.
•
The system must NOT be exposed to dust.
2.7. Room Requirements
•
The room must permit connection to a grounded mains supply which is in accordance with the
local safety standards.
•
The mains connection fuse is adequate for the number of amperes required by all the system
devices.
